The predicament of a man who, desiring to convert to the Gospel, is obliged to repudiate one or more wives with whom he has shared years of conjugal life, is understandable. However polygamy is not in accord with the moral law." [Conjugal] communion is radically contradicted by polygamy; this, in fact, directly negates the plan of God which was Revealed from the beginning, because it is contrary to the equal perSonal dignity of men and women who in matrimony give themselves with a love that is total and therefore unique and exclusive." 179 The Christian who has previously lived in polygamy has a grave duty in justice to honor the obligations contracted in regard to his former wives and his children.

Our moral life has its source in faith in God who Reveals his love to us. St. Paul speaks of the "obedience of faith" 9 as our first obligation. He shows that "ignorance of God" is the principle and explanation of all moral deviations. 10 Our duty toward God is to believe in him and to bear witness to him.

The one and true God first Reveals his glory to Israel. 6 The revelation of the vocation and Truth of man is linked to the revelation of God. Man's vocation is to make God manifest by acting in conformity with his creation "in the image and likeness of God":

The commandments of the Decalogue, although accessible to reaSon alone, have been Revealed. To

The "ten words" are pronounced by God in the midst of a theophany (“The LORD spoke with you face to face at the mountain, out of the midst of the fire." 21 ). They belong to God's revelation of himself and his glory. the gift of the Commandments is the gift of God himself and his holy will. In making his will known, God Reveals himself to his people.

The word "Decalogue" means literally "ten words." 11 God Revealed these "ten words" to his people

Ministries should be exercised in a spirit of fraternal service and dedication to the Church, in the name of the Lord. 81 At the same time the conscience of each perSon should avoid confining itself to individualistic considerations in its moral judgments of the person's own acts. As far as possible conscience should take account of the good of all, as expressed in the moral law, natural and Revealed, and consequently in the law of the Church and in the authoritative teaching of the Magisterium on moral questions. Personal conscience and reason should not be set in opposition to the moral law or the Magisterium of the Church.

This vocation to eternal life is supernatural. It depends entirely on God's gratuitous initiative, for he alone can Reveal and give himself. It surpasses the power of human intellect and will, as that of every other creature. 47

The Law of the Gospel fulfills the commandments of the Law. the Lord's Sermon on the Mount, far from abolishing or devaluing the moral prescriptions of the Old Law, releases their hidden potential and has new demands arise from them: it Reveals their entire divine and human Truth. It does not add new external precepts, but proceeds to reform the heart, the root of human acts, where man chooses between the pure and the impure, 22 where faith, hope, and charity are formed and with them the other virtues. the Gospel thus brings the Law to its fullness through imitation of the perfection of the heavenly Father, through forgiveness of enemies and prayer for persecutors, in emulation of the divine generosity. 23

The first commandment requires us to nourish and protect our faith with prudence and vigilance, and to reject everything that is opposed to it. There are various ways of sinning against faith: Voluntary doubt about the faith disregards or refuses to hold as true what God has Revealed and the Church proposes for belief. Involuntary doubt refers to hesitation in believing, difficulty in overcoming objections connected with the faith, or also anxiety aroused by its obscurity. If deliberately cultivated doubt can lead to spiritual blindness.

Incredulity is the neglect of Revealed Truth or the willful refusal to assent to it. "Heresy is the obstinate post-baptismal denial of some truth which must be believed with divine and catholic faith, or it is likewise an obstinate doubt concerning the same; apostasy is the total repudiation of the Christian faith; schism is the refusal of submission to the Roman Pontiff or of communion with the members of the Church subject to him." 11

In the account of Abel's murder by his brother Cain, 57 Scripture Reveals the presence of anger and envy in man, consequences of original sin, from the beginning of human history. Man has become the enemy of his fellow man. God declares the wickedness of this fratricide: "What have you done? the voice of your brother's blood is crying to me from the ground. and now you are cursed from the ground, which has opened its mouth to receive your brother's blood from your hand." 58

Every institution is inspired, at least implicitly, by a vision of man and his destiny, from which it derives the point of reference for its judgment, its hierarchy of values, its line of conduct. Most societies have formed their institutions in the recognition of a certain preeminence of man over things. Only the divinely Revealed religion has clearly recognized man's origin and destiny in God, the Creator and Redeemer. the Church invites political authorities to measure their judgments and decisions against this inspired Truth about God and man:

Scripture also Reveals in the Lord's day a memorial of Israel's liberation from bondage in Egypt: "You shall remember that you were a servant in the land of Egypt, and the LORD your God brought you out thence with mighty hand and outstretched arm; therefore the LORD your God commanded you to keep the sabbath day." 94

Among all the words of Revelation, there is one which is unique: the Revealed name of God. God confides his name to those who believe in him; he reveals himself to them in his perSonal mystery. the gift of a name belongs to the order of trust and intimacy. "The Lord's name is holy." For this reason man must not abuse it. He must keep it in mind in silent, loving adoration. He will not introduce it into his own speech except to bless, praise, and glorify it. 74

The divine injunction included the prohibition of every representation of God by the hand of man. Deuteronomy explains: "Since you saw no form on the day that the Lord spoke to you at Horeb out of the midst of the fire, beware lest you act corruptly by making a graven image for yourselves, in the form of any figure...." 66 It is the absolutely transcendent God who Revealed himself to Israel. "He is the all," but at the same time "he is greater than all his works." 67 He is "the author of beauty." 68

Agnosticism assumes a number of forms. In certain cases the agnostic refrains from denying God; instead he postulates the existence of a transcendent being which is incapable of Revealing itself, and about which nothing can be said. In other cases, the agnostic makes no judgment about God's existence, declaring it impossible to prove, or even to affirm or deny.

Since it rejects or denies the existence of God, atheism is a sin against the virtue of religion. 61 The imputability of this offense can be significantly diminished in virtue of the intentions and the circumstances. "Believers can have more than a little to do with the rise of atheism. To the extent that they are careless about their instruction in the faith, or present its teaching falsely, or even fail in their religious, moral, or social life, they must be said to conceal rather than to Reveal the true nature of God and of religion." 62

God can Reveal the future to his prophets or to other saints. Still, a sound Christian attitude consists in putting oneself confidently into the hands of Providence for whatever concerns the future, and giving up all unhealthy curiosity about it. Improvidence, however, can constitute a lack of responsibility.

The first commandment forbids honoring Gods other than the one Lord who has Revealed himself to his people. It proscribes superstition and irreligion. Superstition in some sense represents a perverse excess of religion; irreligion is the vice contrary by defect to the virtue of religion.

When God Reveals Himself and calls him, man cannot fully respond to the divine love by his own powers. He must hope that God will give him the capacity to love Him in return and to act in conformity with the commandments of charity. Hope is the confident expectation of divine blessing and the beatific vision of God; it is also the fear of offending God's love and of incurring punishment.

The New Law or the Law of the Gospel is the perfection here on earth of the divine law, natural and Revealed. It is the work of Christ and is expressed particularly in the Sermon on the Mount. It is also the work of the Holy Spirit and through him it becomes the interior law of charity: "I will establish a New Covenant with the house of Israel. . . . I will put my laws into their hands, and write them on their hearts, and I will be their God, and they shall be my people." 19

The Old Law is the first stage of Revealed Law. Its moral prescriptions are summed up in the Ten Commandments. the precepts of the Decalogue lay the foundations for the vocation of man fashioned in the image of God; they prohibit what is contrary to the love of God and neighbor and prescribe what is essential to it. the Decalogue is a light offered to the conscience of every man to make God's call and ways known to him and to protect him against evil:

God, our Creator and Redeemer, chose Israel for himself to be his people and Revealed his Law to them, thus preparing for the coming of Christ. the Law of Moses expresses many Truths naturally accessible to reaSon. These are stated and authenticated within the covenant of salvation.

A sacramental celebration is woven from signs and symbols. In keeping with the divine pedagogy of salvation, their meaning is rooted in the work of creation and in human culture, specified by the events of the Old Covenant and fully Revealed in the perSon and work of Christ.

The book of Revelation of St. John, read in the Church's liturgy, first Reveals to us, "A throne stood in heaven, with one seated on the throne": "the Lord God." 1 It then shows the Lamb, "standing, as though it had been slain": Christ crucified and risen, the one high priest of the true sanctuary, the same one "who offers and is offered, who gives and is given." 2 Finally it presents "the river of the water of life . . . flowing from the throne of God and of the Lamb," one of most beautiful symbols of the Holy Spirit. 3

The catechesis of the liturgy entails first of all an understanding of the sacramental economy (Chapter One). In this light, the innovation of its celebration is Revealed. This chapter will therefore treat of the celebration of the sacraments of the Church. It will consider that which, through the diversity of liturgical traditions, is common to the celebration of the seven sacraments. What is proper to each will be treated later. This fundamental catechesis on the sacramental celebrations responds to the first questions posed by the faithful regarding this subject: - Who celebrates the liturgy? - How is the liturgy celebrated? - When is the liturgy celebrated? - Where is the liturgy celebrated?

For this reaSon the Church, especially during Advent and Lent and above all at the Easter Vigil, re-reads and re-lives the great events of salvation history in the "today" of her liturgy. But this also demands that catechesis help the faithful to open themselves to this spiritual understanding of the economy of salvation as the Church's liturgy Reveals it and enables us to live it.

It is on this harmony of the two Testaments that the Paschal catechesis of the Lord is built, 15 and then, that of the Apostles and the Fathers of the Church. This catechesis unveils what lay hidden under the letter of the Old Testament: the mystery of Christ. It is called "typological" because it Reveals the newness of Christ on the basis of the "figures" (types) which announce him in the deeds, words, and symbols of the first covenant. By this re-reading in the Spirit of Truth, starting from Christ, the figures are unveiled. 16 Thus the flood and Noah's ark prefigured salvation by Baptism, 17 as did the cloud and the crossing of the Red Sea. Water from the rock was the figure of the spiritual gifts of Christ, and manna in the desert prefigured the Eucharist, "the true bread from heaven." 18

In the Church's liturgy the divine blessing is fully Revealed and communicated. the Father is acknowledged and adored as the source and the end of all the blessings of creation and salvation. In his Word who became incarnate, died, and rose for us, he fills us with his blessings. Through his Word, he pours into our hearts the Gift that contains all gifts, the Holy Spirit.

The Last Judgment will come when Christ returns in glory. Only the Father knows the day and the hour; only he determines the moment of its coming. Then through his Son Jesus Christ he will pronounce the final word on all history. We shall know the ultimate meaning of the whole work of creation and of the entire economy of salvation and understand the marvellous ways by which his Providence led everything towards its final end. the Last Judgment will Reveal that God's justice triumphs over all the injustices committed by his creatures and that God's love is stronger than death. 626

In the presence of Christ, who is Truth itself, the truth of each man's relationship with God will be laid bare. 624 The Last Judgment will Reveal even to its furthest consequences the good each perSon has done or failed to do during his earthly life:

God Revealed the resurrection of the dead to his people progressively. Hope in the bodily resurrection of the dead established itself as a consequence intrinsic to faith in God as creator of the whole man, soul and body. the creator of heaven and earth is also the one who faithfully maintains his covenant with Abraham and his posterity. It was in this double perspective that faith in the resurrection came to be expressed. In their trials, the Maccabean martyrs confessed:

"The Roman Pontiff, head of the college of bishops, enjoys this infallibility in virtue of his office, when, as supreme pastor and teacher of all the faithful - who confirms his brethren in the faith he proclaims by a definitive act a doctrine pertaining to faith or morals.... the infallibility promised to the Church is also present in the body of bishops when, together with Peter's successor, they exercise the supreme Magisterium," above all in an Ecumenical Council. 418 When the Church through its supreme Magisterium proposes a doctrine "for belief as being divinely Revealed," 419 and as the teaching of Christ, the definitions "must be adhered to with the obedience of faith." 420 This infallibility extends as far as the deposit of divine Revelation itself. 421

All the signs in the liturgical celebrations are related to Christ: as are sacred images of the holy Mother of God and of the saints as well. They truly signify Christ, who is glorified in them. They make manifest the "cloud of witnesses" 29 who continue to participate in the salvation of the world and to whom we are united, above all in sacramental celebrations. Through their icons, it is man "in the image of God," finally transfigured "into his likeness," 30 who is Revealed to our faith. So too are the angels, who also are recapitulated in Christ:

The hymns and litanies of the Liturgy of the Hours integrate the prayer of the psalms into the age of the Church, expressing the symbolism of the time of day, the liturgical seaSon, or the feast being celebrated. Moreover, the reading from the Word of God at each Hour (with the subsequent responses or troparia) and readings from the Fathers and spiritual masters at certain Hours, Reveal more deeply the meaning of the mystery being celebrated, assist in understanding the psalms, and prepare for silent prayer. the lectio divina, where the Word of God is so read and meditated that it becomes prayer, is thus rooted in the liturgical celebration.

The precepts of natural law are not perceived by everyone clearly and immediately. In the present situation sinful man needs Grace and revelation so moral and religious Truths may be known "by everyone with facility, with firm certainty and with no admixture of error." 12 The natural law provides Revealed law and grace with a foundation prepared by God and in accordance with the work of the Spirit.

There are different expressions of the moral law, all of them interrelated: eternal law - the source, in God, of all law; natural law; Revealed law, comprising the Old Law and the New Law, or Law of the Gospel; finally, civil and ecclesiastical laws.

Faith is the theological virtue by which we believe in God and believe all that he has said and Revealed to us, and that Holy Church proposes for our belief, because he is Truth itself. By faith "man freely commits his entire self to God." 78 For this reaSon the believer seeks to know and do God's will. "The righteous shall live by faith." Living faith "work(s) through charity." 79

The Beatitudes Reveal the goal of human existence, the ultimate end of human acts: God calls us to his own beatitude. This vocation is addressed to each individual perSonally, but also to the Church as a whole, the new people made up of those who have accepted the promise and live from it in faith.

Catechesis has to Reveal in all clarity the joy and the demands of the way of Christ. 22 Catechesis for the "newness of life" 23 in him should be: -a catechesis of the Holy Spirit, the interior Master of life according to Christ, a gentle guest and friend who inspires, guides, corrects, and strengthens this life; -a catechesis of Grace, for it is by grace that we are saved and again it is by grace that our works can bear fruit for eternal life; -a catechesis of the beatitudes, for the way of Christ is summed up in the beatitudes, the only path that leads to the eternal beatitude for which the human heart longs; -a catechesis of sin and forgiveness, for unless man acknowledges that he is a sinner he cannot know the Truth about himself, which is a condition for acting justly; and without the offer of forgiveness he would not be able to bear this truth; -a catechesis of the human virtues which causes one to grasp the beauty and attraction of right dispositions towards goodness; -a catechesis of the Christian virtues of faith, hope, and charity, generously inspired by the example of the saints; -a catechesis of the twofold commandment of charity set forth in the Decalogue; -an ecclesial catechesis, for it is through the manifold exchanges of "spiritual goods" in the "communion of saints" that Christian life can grow, develop, and be communicated.

The Christian meaning of death is Revealed in the light of the Paschal mystery of the death and resurrection of Christ in whom resides our only hope. the Christian who dies in Christ Jesus is "away from the body and at home with the Lord." 183

The process of conversion and repentance was described by Jesus in the parable of the prodigal Son, the center of which is the merciful Father: 37 The fascination of illusory freedom, the abandonment of the father's house; the extreme misery in which the son finds himself after squandering his fortune; his deep humiliation at finding himself obliged to feed swine, and still worse, at wanting to feed on the husks the pigs ate; his reflection on all he has lost; his repentance and decision to declare himself guilty before his father; the journey back; the father's generous welcome; the father's joy - all these are characteristic of the process of conversion. the beautiful robe, the ring, and the festive banquet are symbols of that new life - pure worthy, and joyful - of anyone who returns to God and to the bosom of his family, which is the Church. Only the heart of Christ Who knows the depths of his Father's love could Reveal to us the abyss of his mercy in so simple and beautiful a way.

The proclamation of the Word of God enlightens the candidates and the assembly with the Revealed Truth and elicits the response of faith, which is inseparable from Baptism. Indeed Baptism is "the sacrament of faith" in a particular way, since it is the sacramental entry into the life of faith.

Our Lord voluntarily submitted himself to the baptism of St. John, intended for sinners, in order to "fulfill all righteousness." 19 Jesus' gesture is a manifestation of his self-emptying. 20 The Spirit who had hovered over the waters of the first creation descended then on the Christ as a prelude of the new creation, and the Father Revealed Jesus as his "beloved Son." 21

From the beginning, Jesus associated his disciples with his own life, Revealed the mystery of the Kingdom to them, and gave them a share in his mission, joy, and sufferings. 215 Jesus spoke of a still more intimate communion between him and those who would follow him: "Abide in me, and I in you.... I am the vine, you are the branches." 216 and he proclaimed a mysterious and real communion between his own body and ours: "He who eats my flesh and drinks my blood abides in me, and I in him." 217

Before we make our own this first exclamation of the Lord's Prayer, we must humbly cleanse our hearts of certain false images drawn "from this world." Humility makes us recognize that "no one knows the Son except the Father, and no one knows the Father except the Son and anyone to whom the Son chooses to Reveal him," that is, "to little children." 30 The purification of our hearts has to do with paternal or maternal images, stemming from our personal and cultural history, and influencing our relationship with God. God our Father transcends the categories of the created world. To impose our own ideas in this area "upon him" would be to fabricate idols to adore or pull down. To pray to the Father is to enter into his mystery as he is and as the Son has revealed him to us.

In the Eucharist, the Lord's Prayer also Reveals the eschatological character of its petitions. It is the proper prayer of "the end-time," the time of salvation that began with the outpouring of the Holy Spirit and will be fulfilled with the Lord's return. the petitions addressed to our Father, as distinct from the prayers of the old covenant, rely on the mystery of salvation already accomplished, once for all, in Christ crucified and risen.

In the Eucharistic liturgy the Lord's Prayer appears as the prayer of the whole Church and there Reveals its full meaning and efficacy. Placed between the anaphora (the Eucharistic prayer) and the communion, the Lord's Prayer sums up on the one hand all the petitions and intercessions expressed in the movement of the epiclesis and, on the other, knocks at the door of the Banquet of the kingdom which sacramental communion anticipates.

The traditional expression "the Lord's Prayer" - oratio Dominica - means that the prayer to our Father is taught and given to us by the Lord Jesus. the prayer that comes to us from Jesus is truly unique: it is "of the Lord." On the one hand, in the words of this prayer the only Son gives us the words the Father gave him: 13 he is the master of our prayer. On the other, as Word incarnate, he knows in his human heart the needs of his human brothers and sisters and Reveals them to us: he is the model of our prayer.

Finally, in this prayer Jesus Reveals and gives to us the "knowledge," inseparably one, of the Father and of the Son, 51 which is the very mystery of the life of prayer.

The most common yet most hidden temptation is our lack of faith. It expresses itself less by declared incredulity than by our actual preferences. When we begin to pray, a thousand labors or cares thought to be urgent vie for priority; once again, it is the moment of Truth for the heart: what is its real love? Sometimes we turn to the Lord as a last resort, but do we really believe he is? Sometimes we enlist the Lord as an ally, but our heart remains presumptuous. In each case, our lack of faith Reveals that we do not yet share in the disposition of a humble heart: "Apart from me, you can do nothing." 20

The habitual difficulty in prayer is distraction. It can affect words and their meaning in vocal prayer; it can concern, more profoundly, him to whom we are praying, in vocal prayer (liturgical or perSonal), meditation, and contemplative prayer. To set about hunting down distractions would be to fall into their trap, when all that is necessary is to turn back to our heart: for a distraction Reveals to us what we are attached to, and this humble awareness before the Lord should awaken our preferential love for him and lead us resolutely to offer him our heart to be purified. Therein lies the battle, the choice of which master to serve. 16

The choice of the time and duration of the prayer arises from a determined will, Revealing the secrets of the heart. One does not undertake contemplative prayer only when one has the time: one makes time for the Lord, with the firm determination not to give up, no matter what trials and dryness one may encounter. One cannot always meditate, but one can always enter into inner prayer, independently of the conditions of health, work, or emotional state. the heart is the place of this quest and encounter, in poverty ant in faith.

Prayer in the events of each day and each moment is one of the secrets of the kingdom Revealed to "little children," to the servants of Christ, to the poor of the Beatitudes. It is right and good to pray so that the coming of the kingdom of justice and peace may influence the march of history, but it is just as important to bring the help of prayer into humble, everyday situations; all forms of prayer can be the leaven to which the Lord compares the kingdom. 14

We can invoke God as "Father" because he is Revealed to us by his Son become man and because his Spirit makes him known to us. the personal relation of the Son to the Father is something that man cannot conceive of nor the angelic powers even dimly see: and yet, the Spirit of the Son grants a participation in that very relation to us who believe that Jesus is the Christ and that we are born of God. 32

When we pray to the Father, we are in communion with him and with his Son, Jesus Christ. 33 Then we know and recognize him with an ever new sense of wonder. the first phrase of the Our Father is a blessing of adoration before it is a supplication. For it is the glory of God that we should recognize him as "Father," the true God. We give him thanks for having Revealed his name to us, for the gift of believing in it, and for the indwelling of his Presence in us.

The Holy Spirit makes us discern between trials, which are necessary for the growth of the inner man, 152 and temptation, which leads to sin and death. 153 We must also discern between being tempted and consenting to temptation. Finally, discernment unmasks the lie of temptation, whose object appears to be good, a "delight to the eyes" and desirable, 154 when in reality its fruit is death. God does not want to impose the good, but wants free beings.... There is a certain usefulness to temptation. No one but God knows what our soul has received from him, not even we ourselves. But temptation Reveals it in order to teach us to know ourselves, and in this way we discover our evil inclinations and are obliged to give thanks for the goods that temptation has revealed to us. 155

Finally, in Jesus the name of the Holy God is Revealed and given to us, in the flesh, as Savior, revealed by what he is, by his word, and by his sacrifice. 75 This is the heart of his priestly prayer: "Holy Father . . . for their sake I consecrate myself, that they also may be consecrated in Truth." 76 Because he "sanctifies" his own name, Jesus reveals to us the name of the Father. 77 At the end of Christ's Passover, the Father gives him the name that is above all names: "Jesus Christ is Lord, to the glory of God the Father." 78

In the promise to Abraham and the oath that accompanied it, 71 God commits himself but without disclosing his name. He begins to Reveal it to Moses and makes it known clearly before the eyes of the whole people when he saves them from the Egyptians: "he has triumphed gloriously." 72 From the covenant of Sinai onwards, this people is "his own" and it is to be a "holy (or "consecrated": the same word is used for both in Hebrew) nation," 73 because the name of God dwells in it.

The holiness of God is the inaccessible center of his eternal mystery. What is Revealed of it in creation and history, Scripture calls "glory," the radiance of his majesty. 68 In making man in his image and likeness, God "crowned him with glory and honor," but by sinning, man fell "short of the glory of God." 69 From that time on, God was to manifest his holiness by revealing and giving his name, in order to restore man to the image of his Creator. 70

In the decisive moments of his economy God Reveals his name, but he does so by accomplishing his work. This work, then, is realized for us and in us only if his name is hallowed by us and in us.

The Lord's Prayer brings us into communion with the Father and with his Son, Jesus Christ. At the same time it Reveals us to ourselves (cf GS 22 # 1).

We can invoke God as "Father" because the Son of God made man has Revealed him to us. Jn this Son, through Baptism, we are incorporated and adopted as sons of God.

The baptized cannot pray to "our" Father without bringing before him all those for whom he gave his beloved Son. God's love has no bounds, neither should our prayer. 52 Praying "our" Father opens to us the dimensions of his love Revealed in Christ: praying with and for all who do not yet know him, so that Christ may "gather into one the children of God." 53 God's care for all men and for the whole of creation has inspired all the great practitioners of prayer; it should extend our prayer to the full breadth of love whenever we dare to say "our" Father.

Second, a humble and trusting heart that enables us "to turn and become like children": 41 for it is to "little children" that the Father is Revealed. 42

Thus the Lord's Prayer Reveals us to ourselves at the same time that it reveals the Father to us. 36

Prayer cannot be reduced to the spontaneous outpouring of interior impulse: in order to pray, one must have the will to pray. Nor is it enough to know what the Scriptures Reveal about prayer: one must also learn how to pray. Through a living transmission (Sacred Tradition) within "the believing and praying Church," 1 The Holy Spirit teaches the children of God how to pray.

Thanksgiving characterizes the prayer of the Church which, in celebrating the Eucharist, Reveals and becomes more fully what she is. Indeed, in the work of salvation, Christ sets creation free from sin and death to consecrate it anew and make it return to the Father, for his glory. the thanksgiving of the members of the Body participates in that of their Head.

Christian petition is centered on the desire and search for the Kingdom to come, in keeping with the teaching of Christ. 107 There is a hierarchy in these petitions: we pray first for the Kingdom, then for what is necessary to welcome it and cooperate with its coming. This collaboration with the mission of Christ and the Holy Spirit, which is now that of the Church, is the object of the prayer of the apostolic community. 108 It is the prayer of Paul, the apostle par excellence, which Reveals to us how the divine solicitude for all the churches ought to inspire Christian prayer. 109 By prayer every baptized perSon works for the coming of the Kingdom.

God renews his promise to Jacob, the ancestor of the twelve tribes of Israel. 17 Before confronting his elder brother Esau, Jacob wrestles all night with a mysterious figure who refuses to Reveal his name, but he blesses him before leaving him at dawn. From this account, the spiritual tradition of the Church has retained the symbol of prayer as a battle of faith and as the triumph of perseverance. 18

Prayer is lived in the first place beginning with the realities of creation. the first nine chapters of Genesis describe this relationship with God as an offering of the first-born of Abel's flock, as the invocation of the divine name at the time of Enosh, and as "walking with God. 5 Noah's offering is pleasing to God, who blesses him and through him all creation, because his heart was upright and undivided; Noah, like Enoch before him, "walks with God." 6 This kind of prayer is lived by many righteous people in all religions. In his indefectible covenant with every living creature, 7 God has always called people to prayer. But it is above all beginning with our Father Abraham that prayer is Revealed in the Old Testament.

God calls man first. Man may forget his Creator or hide far from his face; he may run after idols or accuse the deity of having abandoned him; yet the living and true God tirelessly calls each perSon to that mysterious encounter known as prayer. In prayer, the faithful God's initiative of love always comes first; our own first step is always a response. As God gradually Reveals himself and reveals man to himself, prayer appears as a reciprocal call, a covenant drama. Through words and actions, this drama engages the heart. It unfolds throughout the whole history of salvation.

"If you knew the gift of God!" 7 The wonder of prayer is Revealed beside the well where we come seeking water: there, Christ comes to meet every human being. It is he who first seeks us and asks us for a drink. Jesus thirsts; his asking arises from the depths of God's desire for us. Whether we realize it or not, prayer is the encounter of God's thirst with ours. God thirsts that we may thirst for him. 8

"Blessed are the poor in spirit." 337 The Beatitudes Reveal an order of happiness and Grace, of beauty and peace. Jesus celebrates the joy of the poor, to whom the Kingdom already belongs: 338

The practice of goodness is accompanied by spontaneous spiritual joy and moral beauty. Likewise, Truth carries with it the joy and splendor of spiritual beauty. Truth is beautiful in itself. Truth in words, the rational expression of the knowledge of created and uncreated reality, is necessary to man, who is endowed with intellect. But truth can also find other complementary forms of human expression, above all when it is a matter of evoking what is beyond words: the depths of the human heart, the exaltations of the soul, the mystery of God. Even before Revealing himself to man in words of truth, God reveals himself to him through the universal language of creation, the work of his Word, of his wisdom: the order and harmony of the cosmos - which both the child and the scientist discover - "from the greatness and beauty of created things comes a corresponding perception of their Creator," "for the author of beauty created them." 289

Charity and respect for the Truth should dictate the response to every request for information or communication. the good and safety of others, respect for privacy, and the common good are sufficient reaSons for being silent about what ought not be known or for making use of a discreet language. the duty to avoid scandal often commands strict discretion. No one is bound to Reveal the truth to someone who does not have the right to know it. 282

The right to the communication of the Truth is not unconditional. Everyone must conform his life to the Gospel precept of fraternal love. This requires us in concrete situations to judge whether or not it is appropriate to Reveal the truth to someone who asks for it.

The duty of Christians to take part in the life of the Church impels them to act as witnesses of the Gospel and of the obligations that flow from it. This witness is a transmission of the faith in words and deeds. Witness is an act of justice that establishes the Truth or makes it known. 268 All Christians by the example of their lives and the witness of their word, wherever they live, have an obligation to manifest the new man which they have put on in Baptism and to Reveal the power of the Holy Spirit by whom they were strengthened at Confirmation.

Here again the initiative is God's. From the midst of the burning bush he calls Moses. 20 This event will remain one of the primordial images of prayer in the spiritual tradition of Jews and Christians alike. When "the God of Abraham, of Isaac, and of Jacob" calls Moses to be his servant, it is because he is the living God who wants men to live. God Reveals himself in order to save them, though he does not do this alone or despite them: he caLls Moses to be his messenger, an associate in his compassion, his work of salvation. There is something of a divine plea in this mission, and only after long debate does Moses attune his own will to that of the Savior God. But in the dialogue in which God confides in him, Moses also learns how to pray: he balks, makes excuses, above all questions: and it is in response to his question that the Lord confides his ineffable name, which will be revealed through his mighty deeds.

David is par excellence the king "after God's own heart," the shepherd who prays for his people and prays in their name. His submission to the will of God, his praise, and his repentance, will be a model for the prayer of the people. His prayer, the prayer of God's Anointed, is a faithful adherence to the divine promise and expresses a loving and joyful trust in God, the only King and Lord. 28 In the Psalms David, inspired by the Holy Spirit, is the first prophet of Jewish and Christian prayer. the prayer of Christ, the true Messiah and Son of David, will Reveal and fulfill the meaning of this prayer.

In the first place these are prayers that the faithful hear and read in the Scriptures, but also that they make their own - especially those of the Psalms, in view of their fulfillment in Christ. 96 The Holy Spirit, who thus keeps the memory of Christ alive in his Church at prayer, also leads her toward the fullness of Truth and inspires new formulations expressing the unfathomable mystery of Christ at work in his Church's life, sacraments, and mission. These formulations are developed in the great liturgical and spiritual traditions. the forms of prayer Revealed in the apostolic and canonical Scriptures remain normative for Christian prayer.

The Gospel Reveals to us how Mary prays and intercedes in faith. At Cana, 89 The mother of Jesus asks her Son for the needs of a wedding feast; this is the sign of another feast - that of the wedding of the Lamb where he gives his body and blood at the request of the Church, his Bride. It is at the hour of the New Covenant, at the foot of the cross, 90 that Mary is heard as the Woman, the new Eve, the true "Mother of all the living."

Mary's prayer is Revealed to us at the dawning of the fullness of time. Before the incarnation of the Son of God, and before the outpouring of the Holy Spirit, her prayer cooperates in a unique way with the Father's plan of loving kindness: at the Annunciation, for Christ's conception; at Pentecost, for the formation of the Church, his Body. 88 In the faith of his humble handmaid, the Gift of God found the acceptance he had awaited from the beginning of time. She whom the Almighty made "full of Grace" responds by offering her whole being: "Behold I am the handmaid of the Lord; let it be [done] to me according to your word." "Fiat": this is Christian prayer: to be wholly God's, because he is wholly ours.

When Jesus openly entrusts to his disciples the mystery of prayer to the Father, he Reveals to them what their prayer and ours must be, once he has returned to the Father in his glorified humanity. What is new is to "ask in his name." 78 Faith in the Son introduces the disciples into the knowledge of the Father, because Jesus is "the way, and the Truth, and the life." 79 Faith bears its fruit in love: it means keeping the word and the commandments of Jesus, it means abiding with him in the Father who, in him, so loves us that he abides with us. In this new covenant the certitude that our petitions will be heard is founded on the prayer of Jesus. 80

When Jesus prays he is already teaching us how to pray. His prayer to his Father is the theological path (the path of faith, hope, and charity) of our prayer to God. But the Gospel also gives us Jesus' explicit teaching on prayer. Like a wise teacher he takes hold of us where we are and leads us progressively toward the Father. Addressing the crowds following him, Jesus builds on what they already know of prayer from the Old Covenant and opens to them the newness of the coming Kingdom. Then he Reveals this newness to them in parables. Finally, he will speak openly of the Father and the Holy Spirit to his disciples who will be the teachers of prayer in his Church.

The second prayer, before the raising of Lazarus, is recorded by St. John. 50 Thanksgiving precedes the event: "Father, I thank you for having heard me," which implies that the Father always hears his petitions. Jesus immediately adds: "I know that you always hear me," which implies that Jesus, on his part, constantly made such petitions. Jesus' prayer, characterized by thanksgiving, Reveals to us how to ask: before the gift is given, Jesus commits himself to the One who in giving gives himself. the Giver is more precious than the gift; he is the "treasure"; in him abides his Son's heart; the gift is given "as well." 51

The evangelists have preserved two more explicit prayers offered by Christ during his public ministry. Each begins with thanksgiving. In the first, Jesus confesses the Father, acknowledges, and blesses him because he has hidden the mysteries of the Kingdom from those who think themselves learned and has Revealed them to infants, the poor of the Beatitudes. 48 His exclamation, "Yes, Father!" expresses the depth of his heart, his adherence to the Father's "good pleasure," echoing his mother's Fiat at the time of his conception and prefiguring what he will say to the Father in his agony. the whole prayer of Jesus is contained in this loving adherence of his human heart to the mystery of the will of the Father. 49

The Son of God who became Son of the Virgin learned to pray in his human heart. He learns to pray from his mother, who kept all the great things the Almighty had done and treasured them in her heart. 41 He learns to pray in the words and rhythms of the prayer of his people, in the synagogue at Nazareth and the Temple at Jerusalem. But his prayer springs from an otherwise secret source, as he intimates at the age of twelve: "I must be in my Father's house." 42 Here the newness of prayer in the fullness of time begins to be Revealed: his filial prayer, which the Father awaits from his children, is finally going to be lived out by the only Son in his humanity, with and for men.

The drama of prayer is fully Revealed to us in the Word who became flesh and dwells among us. To seek to understand his prayer through what his witnesses proclaim to us in the Gospel is to approach the holy Lord Jesus as Moses approached the burning bush: first to contemplate him in prayer, then to hear how he teaches us to pray, in order to know how he hears our prayer.

After Elijah had learned mercy during his retreat at the Wadi Cherith, he teaches the widow of Zarephath to believe in the Word of God and confirms her faith by his urgent prayer: God brings the widow's child back to life. 33 The sacrifice on Mount Carmel is a decisive test for the faith of the People of God. In response to Elijah's plea, "Answer me, O LORD, answer me," the Lord's fire consumes the holocaust, at the time of the evening oblation. the Eastern liturgies repeat Elijah's plea in the Eucharistic epiclesis. Finally, taking the desert road that leads to the place where the living and true God Reveals himself to his people, Elijah, like Moses before him, hides "in a cleft of he rock" until the mysterious presence of God has passed by. 34 But only on the mountain of the Transfiguration will Moses and Elijah behold the unveiled face of him whom they sought; "the light of the knowledge of the glory of God [shines] in the face of Christ," crucified and risen. 35

The Church's social teaching comprises a body of doctrine, which is articulated as the Church interprets events in the course of history, with the assistance of the Holy Spirit, in the light of the whole of what has been Revealed by Jesus Christ. 201 This teaching can be more easily accepted by men of good will, the more the faithful let themselves be guided by it.

Before his Passover, Jesus announced the sending of "another Paraclete" (Advocate), the Holy Spirit. At work since creation, having previously "spoken through the prophets", the Spirit will now be with and in the disciples, to teach them and guide them "into all the Truth". 68 The Holy Spirit is thus Revealed as another divine perSon with Jesus and the Father.

Out of respect for the holiness of God, the people of Israel do not pronounce his name. In the reading of Sacred Scripture, the Revealed name (YHWH) is replaced by the divine title "LORD" (in Hebrew Adonai, in Greek Kyrios). It is under this title that the divinity of Jesus will be acclaimed: "Jesus is LORD."

By Revealing his name God at the same time reveals his faithfulness which is from everlasting to everlasting, valid for the past ("I am the God of your Father"), as for the future ("I will be with you"). 12 God, who reveals his name as "I AM", reveals himself as the God who is always there, present to his people in order to save them.

In Revealing his mysterious name, YHWH ("I AM HE WHO IS", "I AM WHO AM" or "I AM WHO I AM"), God says who he is and by what name he is to be called. This divine name is mysterious just as God is mystery. It is at once a name revealed and something like the refusal of a name, and hence it better expresses God as what he is - infinitely above everything that we can understand or say: he is the "hidden God", his name is ineffable, and he is the God who makes himself close to men. 11

God Revealed himself progressively and under different names to his people, but the revelation that proved to be the fundamental one for both the Old and the New Covenants was the revelation of the divine name to Moses in the theophany of the burning bush, on the threshold of the Exodus and of the covenant on Sinai.

God Revealed himself to his people Israel by making his name known to them. A name expresses a perSon's essence and identity and the meaning of this person's life. God has a name; he is not an anonymous force. To disclose one's name is to make oneself known to others; in a way it is to hand oneself over by becoming accessible, capable of being known more intimately and addressed personally.

To Israel, his chosen, God Revealed himself as the only One: "Hear, O Israel: the LORD our God is one LORD; and you shall love the LORD your God with all your heart, and with all your soul, and with all your might." 4 Through the prophets, God calls Israel and all nations to turn to him, the one and only God: "Turn to me and be saved, all the ends of the earth! For I am God, and there is no other.. . To me every knee shall bow, every tongue shall swear. 'Only in the LORD, it shall be said of me, are righteousness and strength.'" 5

"I believe in God": this first affirmation of the Apostles' Creed is also the most fundamental. the whole Creed speaks of God, and when it also speaks of man and of the world it does so in relation to God. the other articles of the Creed all depend on the first, just as the remaining Commandments make the first explicit. the other articles help us to know God better as he Revealed himself progressively to men. "The faithful first profess their belief in God." 2

Faith is a perSonal act - the free response of the human person to the initiative of God who Reveals himself. But faith is not an isolated act. No one can believe alone, just as no one can live alone. You have not given yourself faith as you have not given yourself life. the believer has received faith from others and should hand it on to others. Our love for Jesus and for our neighbour impels us to speak to others about our faith. Each believer is thus a link in the great chain of believers. I cannot believe without being carried by the faith of others, and by my faith I help support others in the faith.

The divine name, "I Am" or "He Is", expresses God's faithfulness: despite the faithlessness of men's sin and the punishment it deserves, he keeps "steadfast love for thousands". 21 By going so far as to give up his own Son for us, God Reveals that he is "rich in mercy". 22 By giving his life to free us from sin, Jesus reveals that he himself bears the divine name: "When you have lifted up the Son of man, then you will realize that "I AM"." 23

God, "HE WHO IS", Revealed himself to Israel as the one "abounding in steadfast love and faithfulness". 27 These two terms express summarily the riches of the divine name. In all his works God displays, not only his kindness, goodness, Grace and steadfast love, but also his trustworthiness, constancy, faithfulness and Truth. "I give thanks to your name for your steadfast love and your faithfulness." 28 He is the Truth, for "God is light and in him there is no darkness"; "God is love", as the apostle John teaches. 29

Jesus Revealed that God is Father in an unheard-of sense: he is Father not only in being Creator; he is eternally Father by his relationship to his only Son who, reciprocally, is Son only in relation to his Father: "No one knows the Son except the Father, and no one knows the Father except the Son and any one to whom the Son chooses to reveal him." 64

The Trinity is a mystery of faith in the strict sense, one of the "mysteries that are hidden in God, which can never be known unless they are Revealed by God". 58 To be sure, God has left traces of his Trinitarian being in his work of creation and in his Revelation throughout the Old Testament. But his inmost Being as Holy Trinity is a mystery that is inaccessible to reaSon alone or even to Israel's faith before the Incarnation of God's Son and the sending of the Holy Spirit.

The Fathers of the Church distinguish between theology (theologia) and economy (oikonomia). "Theology" refers to the mystery of God's inmost life within the Blessed Trinity and "economy" to all the works by which God Reveals himself and communicates his life. Through the oikonomia the theologia is revealed to us; but conversely, the theologia illuminates the whole oikonomia. God's works reveal who he is in himself; the mystery of his inmost being enlightens our understanding of all his works. So it is, analogously, among human perSons. A person discloses himself in his actions, and the better we know a person, the better we understand his actions.

This paragraph expounds briefly (I) how the mystery of the Blessed Trinity was Revealed, (II) how the Church has articulated the doctrine of the faith regarding this mystery, and (III) how, by the divine missions of the Son and the Holy Spirit, God the Father fulfils the "plan of his loving goodness" of creation, redemption and sanctification.

The mystery of the Most Holy Trinity is the central mystery of Christian faith and life. It is the mystery of God in himself. It is therefore the source of all the other mysteries of faith, the light that enlightens them. It is the most fundamental and essential teaching in the "hierarchy of the Truths of faith". 56 The whole history of salvation is identical with the history of the way and the means by which the one true God, Father, Son and Holy Spirit, Reveals himself to men "and reconciles and unites with himself those who turn away from sin". 57

But St. John goes even further when he affirms that "God is love": 44 God's very being is love. By sending his only Son and the Spirit of Love in the fullness of time, God has Revealed his innermost secret: 45 God himself is an eternal exchange of love, Father, Son and Holy Spirit, and he has destined us to share in that exchange.

In the course of its history, Israel was able to discover that God had only one reaSon to Reveal himself to them, a single motive for choosing them from among all peoples as his special possession: his sheer gratuitous love. 38 and thanks to the prophets Israel understood that it was again out of love that God never stopped saving them and pardoning their unfaithfulness and sins. 39

God is also Truthful when he Reveals himself - the teaching that comes from God is "true instruction". 35 When he sends his Son into the world it will be "to bear witness to the truth": 36 "We know that the Son of God has come and has given us understanding, to know him who is true." 37

Faith and science: "Though faith is above reaSon, there can never be any real discrepancy between faith and reason. Since the same God who Reveals mysteries and infuses faith has bestowed the light of reason on the human mind, God cannot deny himself, nor can Truth ever contradict truth." 37 "Consequently, methodical research in all branches of knowledge, provided it is carried out in a truly scientific manner and does not override moral laws, can never conflict with the faith, because the things of the world and the things of faith derive from the same God. the humble and persevering investigator of the secrets of nature is being led, as it were, by the hand of God in spite of himself, for it is God, the conserver of all things, who made them what they are." 38

"Faith seeks understanding": 33 it is intrinsic to faith that a believer desires to know better the One in whom he has put his faith, and to understand better what He has Revealed; a more penetrating knowledge will in turn call forth a greater faith, increasingly set afire by love. the Grace of faith opens "the eyes of your hearts" 34 to a lively understanding of the contents of Revelation: that is, of the totality of God's plan and the mysteries of faith, of their connection with each other and with Christ, the centre of the revealed mystery. "The same Holy Spirit constantly perfects faith by his gifts, so that Revelation may be more and more profoundly understood." 35 In the words of St. Augustine, "I believe, in order to understand; and I understand, the better to believe." 36

Faith is certain. It is more certain than all human knowledge because it is founded on the very word of God who cannot lie. To be sure, Revealed Truths can seem obscure to human reaSon and experience, but "the certainty that the divine light gives is greater than that which the light of natural reason gives." 31 "Ten thousand difficulties do not make one doubt." 32

"Yet this Magisterium is not superior to the Word of God, but is its servant. It teaches only what has been handed on to it. At the divine command and with the help of the Holy Spirit, it listens to this devotedly, guards it with dedication and expounds it faithfully. All that it proposes for belief as being divinely Revealed is drawn from this single deposit of faith." 48

As a result the Church, to whom the transmission and interpretation of Revelation is entrusted, "does not derive her certainty about all Revealed Truths from the holy Scriptures alone. Both Scripture and Tradition must be accepted and honoured with equal sentiments of devotion and reverence." 44

God, who "dwells in unapproachable light", wants to communicate his own divine life to the men he freely created, in order to adopt them as his Sons in his only-begotten Son. 3 By Revealing himself God wishes to make them capable of responding to him, and of knowing him and of loving him far beyond their own natural capacity.

"It pleased God, in his goodness and wisdom, to Reveal himself and to make known the mystery of his will. His will was that men should have access to the Father, through Christ, the Word made flesh, in the Holy Spirit, and thus become sharers in the divine nature." 2

By natural reaSon man can know God with certainty, on the basis of his works. But there is another order of knowledge, which man cannot possibly arrive at by his own powers: the order of divine Revelation. 1 Through an utterly free decision, God has Revealed himself and given himself to man. This he does by revealing the mystery, his plan of loving goodness, formed from all eternity in Christ, for the benefit of all men. God has fully revealed this plan by sending us his beloved Son, our Lord Jesus Christ, and the Holy Spirit.

Man's faculties make him capable of coming to a knowledge of the existence of a perSonal God. But for man to be able to enter into real intimacy with him, God willed both to Reveal himself to man, and to give him the Grace of being able to welcome this revelation in faith.(so) the proofs of God's existence, however, can predispose one to faith and help one to see that faith is not opposed to reason.

All the faithful share in understanding and handing on Revealed Truth. They have received the anointing of the Holy Spirit, who instructs them 53 and guides them into all truth. 54

Thanks to the assistance of the Holy Spirit, the understanding of both the realities and the words of the heritage of faith is able to grow in the life of the Church: - "through the contemplation and study of believers who ponder these things in their hearts"; 57 it is in particular "theological research [which] deepens knowledge of Revealed Truth". 58 - "from the intimate sense of spiritual realities which [believers] experience", 59 The sacred Scriptures "grow with the one who reads them." 60 - "from the preaching of those who have received, along with their right of succession in the episcopate, the sure charism of truth". 61

What moves us to believe is not the fact that Revealed Truths appear as true and intelligible in the light of our natural reaSon: we believe "because of the authority of God himself who reveals them, who can neither deceive nor be deceived". 28 So "that the submission of our faith might nevertheless be in accordance with reason, God willed that external proofs of his Revelation should be joined to the internal helps of the Holy Spirit." 29 Thus the miracles of Christ and the saints, prophecies, the Church's growth and holiness, and her fruitfulness and stability "are the most certain signs of divine Revelation, adapted to the intelligence of all"; they are "motives of credibility" (motiva credibilitatis), which show that the assent of faith is "by no means a blind impulse of the mind". 30

Believing is possible only by Grace and the interior helps of the Holy Spirit. But it is no less true that believing is an authentically human act. Trusting in God and cleaving to the Truths he has Revealed is contrary neither to human freedom nor to human reaSon. Even in human relations it is not contrary to our dignity to believe what other persons tell us about themselves and their intentions, or to trust their promises (for example, when a man and a woman marry) to share a communion of life with one another. If this is so, still less is it contrary to our dignity to "yield by faith the full submission of... intellect and will to God who reveals", 26 and to share in an interior communion with him.

One cannot believe in Jesus Christ without sharing in his Spirit. It is the Holy Spirit who Reveals to men who Jesus is. For "no one can say "Jesus is Lord", except by the Holy Spirit", 22 who "searches everything, even the depths of God. . No one comprehends the thoughts of God, except the Spirit of God." 23 Only God knows God completely: we believe in the Holy Spirit because he is God.

For a Christian, believing in God cannot be separated from believing in the One he sent, his "beloved Son", in whom the Father is "well pleased"; God tells us to listen to him. 18 The Lord himself said to his disciples: "Believe in God, believe also in me." 19 We can believe in Jesus Christ because he is himself God, the Word made flesh: "No one has ever seen God; the only Son, who is in the bosom of the Father, he has made him known." 20 Because he "has seen the Father", Jesus Christ is the only one who knows him and can Reveal him. 21

Faith is first of all a perSonal adherence of man to God. At the same time, and inseparably, it is a free assent to the whole Truth that God has Revealed. As personal adherence to God and assent to his truth, Christian faith differs from our faith in any human person. It is right and just to entrust oneself wholly to God and to believe absolutely what he says. It would be futile and false to place such faith in a creature. 17

By faith, man completely submits his intellect and his will to God. 2 With his whole being man gives his assent to God the Revealer. Sacred Scripture calls this human response to God, the author of revelation, "the obedience of faith". 3

In Sacred Scripture, God speaks to man in a human way. To interpret Scripture correctly, the reader must be attentive to what the human authors truly wanted to affirm, and to what God wanted to Reveal to us by their words. 75

God is the author of Sacred Scripture. "The divinely Revealed realities, which are contained and presented in the text of Sacred Scripture, have been written down under the inspiration of the Holy Spirit." 69

In order to Reveal himself to men, in the condescension of his goodness God speaks to them in human words: "Indeed the words of God, expressed in the words of men, are in every way like human language, just as the Word of the eternal Father, when he took on himself the flesh of human weakness, became like men." 63

We begin our profession of faith by saying: "I believe" or "We believe". Before expounding the Church's faith, as confessed in the Creed, celebrated in the liturgy and lived in observance of God's commandments and in prayer, we must first ask what "to believe" means. Faith is man's response to God, who Reveals himself and gives himself to man, at the same time bringing man a superabundant light as he searches for the ultimate meaning of his life. Thus we shall consider first that search (Chapter One), then the divine Revelation by which God comes to meet man (Chapter Two), and finally the response of faith (Chapter Three).

The Greek word mysterion was translated into Latin by two terms: mystenum and sacramentum. In later usage the term sacramentum emphasizes the visible sign of the hidden reality of salvation which was indicated by the term mystenum. In this sense, Christ himself is the mystery of salvation: "For there is no other mystery of God, except Christ." 196 The saving work of his holy and sanctifying humanity is the sacrament of salvation, which is Revealed and active in the Church's sacraments (which the Eastern Churches also call "the holy mysteries"). the seven sacraments are the signs and instruments by which the Holy Spirit spreads the Grace of Christ the head throughout the Church which is his Body. the Church, then, both contains and communicates the invisible grace she signifies. It is in this analogical sense, that the Church is called a "sacrament."

The Paschal mystery has two aspects: by his death, Christ liberates us from sin; by his Resurrection, he opens for us the way to a new life. This new life is above all justification that reinstates us in God's Grace, "so that as Christ was raised from the dead by the glory of the Father, we too might walk in newness of life." Justification consists in both victory over the death caused by sin and a new participation in grace. 526 It brings about filial adoption so that men become Christ's brethren, as Jesus himself called his disciples after his Resurrection: "Go and tell my brethren." 527 We are brethren not by nature, but by the gift of grace, because that adoptive filiation gains us a real share in the life of the only Son, which was fully Revealed in his Resurrection.

Christ's Resurrection is an object of faith in that it is a transcendent intervention of God himself in creation and history. In it the three divine perSons act together as one, and manifest their own proper characteristics. the Father's power "raised up" Christ his Son and by doing so perfectly introduced his Son's humanity, including his body, into the Trinity. Jesus is conclusively Revealed as "Son of God in power according to the Spirit of holiness by his Resurrection from the dead". 514 St. Paul insists on the manifestation of God's power 515 through the working of the Spirit who gave life to Jesus' dead humanity and called it to the glorious state of Lordship.

O truly blessed Night, sings the Exsultet of the Easter Vigil, which alone deserved to know the time and the hour when Christ rose from the realm of the dead! 512 But no one was an eyewitness to Christ's Resurrection and no evangelist describes it. No one can say how it came about physically. Still less was its innermost essence, his passing over to another life, perceptible to the senses. Although the Resurrection was an historical event that could be verified by the sign of the empty tomb and by the reality of the apostles' encounters with the risen Christ, still it remains at the very heart of the mystery of faith as something that transcends and surpasses history. This is why the risen Christ does not Reveal himself to the world, but to his disciples, "to those who came up with him from Galilee to Jerusalem, who are now his witnesses to the people." 513

Given all these testimonies, Christ's Resurrection cannot be interpreted as something outside the physical order, and it is impossible not to acknowledge it as an historical fact. It is clear from the facts that the disciples' faith was drastically put to the test by their master's Passion and death on the cross, which he had foretold. 502 The shock provoked by the Passion was so great that at least some of the disciples did not at once believe in the news of the Resurrection. Far from showing us a community seized by a mystical exaltation, the Gospels present us with disciples demoralized ("looking sad" 503 ) and frightened. For they had not believed the holy women returning from the tomb and had regarded their words as an "idle tale". 504 When Jesus Reveals himself to the Eleven on Easter evening, "he upbraided them for their unbelief and hardness of heart, because they had not believed those who saw him after he had risen." 505

"By the Grace of God" Jesus tasted death "for every one". 459 In his plan of salvation, God ordained that his Son should not only "die for our sins" 460 but should also "taste death", experience the condition of death, the separation of his soul from his body, between the time he expired on the cross and the time he was raised from the dead. the state of the dead Christ is the mystery of the tomb and the descent into hell. It is the mystery of Holy Saturday, when Christ, lying in the tomb, 461 Reveals God's great sabbath rest 462 after the fulfilment 463 of man's salvation, which brings peace to the whole universe. 464

After agreeing to baptize him along with the sinners, John the Baptist looked at Jesus and pointed him out as the "Lamb of God, who takes away the sin of the world". 422 By doing so, he Reveals that Jesus is at the same time the suffering Servant who silently allows himself to be led to the slaughter and who bears the sin of the multitudes, and also the Paschal Lamb, the symbol of Israel's redemption at the first Passover. 423 Christ's whole life expresses his mission: "to serve, and to give his life as a ransom for many." 424

Jesus gave scandal above all when he identified his merciful conduct toward sinners with God's own attitude toward them. 367 He went so far as to hint that by sharing the table of sinners he was admitting them to the messianic banquet. 368 But it was most especially by forgiving sins that Jesus placed the religious authorities of Israel on the horns of a dilemma. Were they not entitled to demand in consternation, "Who can forgive sins but God alone?" 369 By forgiving sins Jesus either is blaspheming as a man who made himself God's equal, or is speaking the Truth and his perSon really does make present and Reveal God's name. 370

Going even further, Jesus perfects the dietary law, so important in Jewish daily life, by Revealing its pedagogical meaning through a divine interpretation: "Whatever goes into a man from outside cannot defile him. . . (Thus he declared all foods clean.). . . What comes out of a man is what defiles a man. For from within, out of the heart of man, come evil thoughts. . ." 346 In presenting with divine authority the definitive interpretation of the Law, Jesus found himself confronted by certain teachers of the Law who did not accept his interpretation of the Law, guaranteed though it was by the divine signs that accompanied it. 347 This was the case especially with the sabbath laws, for he recalls, often with rabbinical arguments, that the sabbath rest is not violated by serving God and neighbour, 348 which his own healings did.

For a moment Jesus discloses his divine glory, confirming Peter's confession. He also Reveals that he will have to go by the way of the cross at Jerusalem in order to "enter into his glory". 295 Moses and Elijah had seen God's glory on the Mountain; the Law and the Prophets had announced the Messiah's sufferings. 296 Christ's Passion is the will of the Father: the Son acts as God's servant; 297 The cloud indicates the presence of the Holy Spirit. "The whole Trinity appeared: the Father in the voice; the Son in the man; the Spirit in the shining cloud." 298

Through his Grace, the Holy Spirit is the first to awaken faith in us and to communicate to us the new life, which is to "know the Father and the one whom he has sent, Jesus Christ." 4 But the Spirit is the last of the perSons of the Holy Trinity to be Revealed. St. Gregory of Nazianzus, the Theologian, explains this progression in terms of the pedagogy of divine "condescension":

It is in the Church that Christ fulfills and Reveals his own mystery as the purpose of God's plan: "to unite all things in him." 189 St. Paul calls the nuptial union of Christ and the Church "a great mystery." Because she is united to Christ as to her bridegroom, she becomes a mystery in her turn. 190 Contemplating this mystery in her, Paul exclaims: "Christ in you, the hope of glory." 191

On that day, the Holy Trinity is fully Revealed. Since that day, the Kingdom announced by Christ has been open to those who believe in him: in the humility of the flesh and in faith, they already share in the communion of the Holy Trinity. By his coming, which never ceases, the Holy Spirit causes the world to enter into the "last days," the time of the Church, the Kingdom already inherited though not yet consummated.

Jesus does not Reveal the Holy Spirit fully, until he himself has been glorified through his Death and Resurrection. Nevertheless, little by little he alludes to him even in his teaching of the multitudes, as when he reveals that his own flesh will be food for the life of the world. 110 He also alludes to the Spirit in speaking to Nicodemus, 111 to the Samaritan woman, 112 and to those who take part in the feast of Tabernacles. 113 To his disciples he speaks openly of the Spirit in connection with prayer 114 and with the witness they will have to bear. 115

The Messiah's characteristics are Revealed above all in the "Servant Songs." 82 These songs proclaim the meaning of Jesus' Passion and show how he will pour out the Holy Spirit to give life to the many: not as an outsider, but by embracing our "form as slave." 83 Taking our death upon himself, he can communicate to us his own Spirit of life.

Theophanies (manifestations of God) light up the way of the promise, from the patriarchs to Moses and from Joshua to the visions that inaugurated the missions of the great prophets. Christian tradition has always recognized that God's Word allowed himself to be seen and heard in these theophanies, in which the cloud of the Holy Spirit both Revealed him and concealed him in its shadow.

From the beginning until "the fullness of time," 60 The joint mission of the Father's Word and Spirit remains hidden, but it is at work. God's Spirit prepares for the time of the Messiah. Neither is fully Revealed but both are already promised, to be watched for and welcomed at their manifestation. So, for this reaSon, when the Church reads the Old Testament, she searches there for what the Spirit, "who has spoken through the prophets," wants to tell us about Christ. 61

Cloud and light. These two images occur together in the manifestations of the Holy Spirit. In the theophanies of the Old Testament, the cloud, now obscure, now luminous, Reveals the living and saving God, while veiling the transcendence of his glory - with Moses on Mount Sinai, 43 at the tent of meeting, 44 and during the wandering in the desert, 45 and with Solomon at the dedication of the Temple. 46 In the Holy Spirit, Christ fulfills these figures. the Spirit comes upon the Virgin Mary and "overshadows" her, so that she might conceive and give birth to Jesus. 47 On the mountain of Transfiguration, the Spirit in the "cloud came and overshadowed" Jesus, Moses and Elijah, Peter, James and John, and "a voice came out of the cloud, saying, 'This is my Son, my Chosen; listen to him!'" 48 Finally, the cloud took Jesus out of the sight of the disciples on the day of his ascension and will reveal him as Son of man in glory on the day of his final coming. 49

The One whom the Father has sent into our hearts, the Spirit of his Son, is truly God. 10 Consubstantial with the Father and the Son, the Spirit is inseparable from them, in both the inner life of the Trinity and his gift of love for the world. In adoring the Holy Trinity, life-giving, consubstantial, and indivisible, the Church's faith also professes the distinction of persons. When the Father sends his Word, he always sends his Breath. In their joint mission, the Son and the Holy Spirit are distinct but inseparable. To be sure, it is Christ who is seen, the visible image of the invisible God, but it is the Spirit who Reveals him.

"No one comprehends the thoughts of God except the Spirit of God." 7 Now God's Spirit, who Reveals God, makes known to us Christ, his Word, his living Utterance, but the Spirit does not speak of himself. the Spirit who "has spoken through the prophets" makes us hear the Father's Word, but we do not hear the Spirit himself. We know him only in the movement by which he reveals the Word to us and disposes us to welcome him in faith. the Spirit of Truth who "unveils" Christ to us "will not speak on his own." 8 Such properly divine self-effacement explains why "the world cannot receive (him), because it neither sees him nor knows him," while those who believe in Christ know the Spirit because he dwells with them. 9

The Holy Spirit is at work with the Father and the Son from the beginning to the completion of the plan for our salvation. But in these "end times," ushered in by the Son's redeeming Incarnation, the Spirit is Revealed and given, recognized and welcomed as a person. Now can this divine plan, accomplished in Christ, the firstborn and head of the new creation, be embodied in mankind by the outpouring of the Spirit: as the Church, the communion of saints, the forgiveness of sins, the resurrection of the body, and the life everlasting.

The kingdom belongs to the poor and lowly, which means those who have accepted it with humble hearts. Jesus is sent to "preach good news to the poor"; 253 he declares them blessed, for "theirs is the kingdom of heaven." 254 To them - the "little ones" the Father is pleased to Reveal what remains hidden from the wise and the learned. 255 Jesus shares the life of the poor, from the cradle to the cross; he experiences hunger, thirst and privation. 256 Jesus identifies himself with the poor of every kind and makes active love toward them the condition for entering his kingdom. 257

Jesus' temptation Reveals the way in which the Son of God is Messiah, contrary to the way Satan proposes to him and the way men wish to attribute to him. 244 This is why Christ vanquished the Tempter for us: "For we have not a high priest who is unable to sympathize with our weaknesses, but one who in every respect has been tested as we are, yet without sinning." 245 By the solemn forty days of Lent the Church unites herself each year to the mystery of Jesus in the desert.

The evangelists indicate the salvific meaning of this mysterious event: Jesus is the new Adam who remained faithful just where the first Adam had given in to temptation. Jesus fulfils Israel's vocation perfectly: in contrast to those who had once provoked God during forty years in the desert, Christ Reveals himself as God's Servant, totally obedient to the divine will. In this, Jesus is the devil's conqueror: he "binds the strong man" to take back his plunder. 243 Jesus' victory over the tempter in the desert anticipates victory at the Passion, the supreme act of obedience of his filial love for the Father.

"In the beginning was the Word. . . and the Word was God. . . all things were made through him, and without him was not anything made that was made." 129 The New Testament Reveals that God created everything by the eternal Word, his beloved Son. In him "all things were created, in heaven and on earth.. . all things were created through him and for him. He is before all things, and in him all things hold together." 130 The Church's faith likewise confesses the creative action of the Holy Spirit, the "giver of life", "the Creator Spirit" (Veni, Creator Spiritus), the "source of every good". 131

Thus the revelation of creation is inseparable from the revelation and forging of the covenant of the one God with his People. Creation is Revealed as the first step towards this covenant, the first and universal witness to God's all-powerful love. 126 and so, the Truth of creation is also expressed with growing vigour in the message of the prophets, the prayer of the psalms and the liturgy, and in the wisdom sayings of the Chosen People. 127

The Truth about creation is so important for all of human life that God in his tenderness wanted to Reveal to his People everything that is salutary to know on the subject. Beyond the natural knowledge that every man can have of the Creator, 124 God progressively revealed to Israel the mystery of creation. He who chose the patriarchs, who brought Israel out of Egypt, and who by choosing Israel created and formed it, this same God reveals himself as the One to whom belong all the peoples of the earth, and the whole earth itself; he is the One who alone "made heaven and earth". 125

Creation is the foundation of "all God's saving plans," the "beginning of the history of salvation" 117 that culminates in Christ. Conversely, the mystery of Christ casts conclusive light on the mystery of creation and Reveals the end for which "in the beginning God created the heavens and the earth": from the beginning, God envisaged the glory of the new creation in Christ. 118

Faith in God the Father Almighty can be put to the test by the experience of evil and suffering. God can sometimes seem to be absent and incapable of stopping evil. But in the most mysterious way God the Father has Revealed his almighty power in the voluntary humiliation and Resurrection of his Son, by which he conquered evil. Christ crucified is thus "the power of God and the wisdom of God. For the foolishness of God is wiser than men, and the weakness of God is stronger than men." 111 It is in Christ's Resurrection and exaltation that the Father has shown forth "the immeasurable greatness of his power in us who believe". 112

God is the Father Almighty, whose fatherhood and power shed light on one another: God Reveals his fatherly omnipotence by the way he takes care of our needs; by the filial adoption that he gives us ("I will be a father to you, and you shall be my Sons and daughters, says the Lord Almighty"): 109 finally by his infinite mercy, for he displays his power at its height by freely forgiving sins.

From the beginning, the Revealed Truth of the Holy Trinity has been at the very root of the Church's living faith, principally by means of Baptism. It finds its expression in the rule of baptismal faith, formulated in the preaching, catechesis and prayer of the Church. Such formulations are already found in the apostolic writings, such as this salutation taken up in the Eucharistic liturgy: "The Grace of the Lord Jesus Christ and the love of God and the fellowship of the Holy Spirit be with you all." 81

The Old Testament suggests and the New Covenant Reveals the creative action of the Son and the Spirit, 132 inseparably one with that of the Father. This creative co-operation is clearly affirmed in the Church's rule of faith: "There exists but one God. . . he is the Father, God, the Creator, the author, the giver of order. He made all things by himself, that is, by his Word and by his Wisdom", "by the Son and the Spirit" who, so to speak, are "his hands". 133 Creation is the common work of the Holy Trinity.

God himself created the visible world in all its richness, diversity and order. Scripture presents the work of the Creator symbolically as a succession of six days of divine "work", concluded by the "rest" of the seventh day. 204 On the subject of creation, the sacred text teaches the Truths Revealed by God for our salvation, 205 permitting us to "recognize the inner nature, the value and the ordering of the whole of creation to the praise of God." 206

During the greater part of his life Jesus shared the condition of the vast majority of human beings: a daily life spent without evident greatness, a life of manual labour. His religious life was that of a Jew obedient to the law of God, 221 a life in the community. From this whole period it is Revealed to us that Jesus was "obedient" to his parents and that he "increased in wisdom and in stature, and in favour with God and man." 222

The Gospels were written by men who were among the first to have the faith 174 and wanted to share it with others. Having known in faith who Jesus is, they could see and make others see the traces of his mystery in all his earthly life. From the swaddling clothes of his birth to the vinegar of his Passion and the shroud of his Resurrection, everything in Jesus' life was a sign of his mystery. 175 His deeds, miracles and words all Revealed that "in him the whole fullness of deity dwells bodily." 176 His humanity appeared as "sacrament", that is, the sign and instrument, of his divinity and of the salvation he brings: what was visible in his earthly life leads to the invisible mystery of his divine Sonship and redemptive mission

By its union to the divine wisdom in the perSon of the Word incarnate, Christ enjoyed in his human knowledge the fullness of understanding of the eternal plans he had come to Reveal. 108 What he admitted to not knowing in this area, he elsewhere declared himself not sent to reveal. 109

The Word became flesh for us in order to save us by reconciling us with God, who "loved us and sent his Son to be the expiation for our sins": "the Father has sent his Son as the Saviour of the world", and "he was Revealed to take away sins": 70

In the Greek translation of the Old Testament, the ineffable Hebrew name YHWH, by which God Revealed himself to Moses, 59 is rendered as Kyrios, "Lord". From then on, "Lord" becomes the more usual name by which to indicate the divinity of Israel's God. the New Testament uses this full sense of the title "Lord" both for the Father and - what is new - for Jesus, who is thereby recognized as God Himself. 60

Such is not the case for Simon Peter when he confesses Jesus as "the Christ, the Son of the living God", for Jesus responds solemnly: "Flesh and blood has not Revealed this to you, but my Father who is in heaven." 46 Similarly Paul will write, regarding his conversion on the road to Damascus, "When he who had set me apart before I was born, and had called me through his Grace, was pleased to reveal his Son to me, in order that I might preach him among the Gentiles..." 47 "and in the synagogues immediately [Paul] proclaimed Jesus, saying, 'He is the Son of God.'" 48 From the beginning this acknowledgment of Christ's divine sonship will be the centre of the apostolic faith, first professed by Peter as the Church's foundation. 49

Jesus accepted Peter's profession of faith, which acknowledged him to be the Messiah, by announcing the imminent Passion of the Son of Man. 40 He unveiled the authentic content of his messianic kingship both in the transcendent identity of the Son of Man "who came down from heaven", and in his redemptive mission as the suffering Servant: "The Son of Man came not to be served but to serve, and to give his life as a ransom for many." 41 Hence the true meaning of his kingship is Revealed only when he is raised high on the cross. 42 Only after his Resurrection will Peter be able to proclaim Jesus' messianic kingship to the People of God: "Let all the house of Israel therefore know assuredly that God has made him both Lord and Christ, this Jesus whom you crucified." 43

Jesus' messianic consecration Reveals his divine mission, "for the name 'Christ' implies 'he who anointed', 'he who was anointed' and 'the very anointing with which he was anointed'. the one who anointed is the Father, the one who was anointed is the Son, and he was anointed with the Spirit who is the anointing.'" 35 His eternal messianic consecration was revealed during the time of his earthly life at the moment of his baptism by John, when "God anointed Jesus of Nazareth with the Holy Spirit and with power", "that he might be revealed to Israel" 36 as its Messiah. His works and words will manifest him as "the Holy One of God". 37

"At the heart of catechesis we find, in essence, a PerSon, the Person of Jesus of Nazareth, the only Son from the Father. . .who suffered and died for us and who now, after rising, is living with us forever." 13 To catechize is "to Reveal in the Person of Christ the whole of God's eternal design reaching fulfilment in that Person. It is to seek to understand the meaning of Christ's actions and words and of the signs worked by him." 14 Catechesis aims at putting "people . . . in communion . . . with Jesus Christ: only he can lead us to the love of the Father in the Spirit and make us share in the life of the Holy Trinity." 15

With the progress of Revelation, the reality of sin is also illuminated. Although to some extent the People of God in the Old Testament had tried to understand the pathos of the human condition in the light of the history of the fall narrated in Genesis, they could not grasp this story's ultimate meaning, which is Revealed only in the light of the death and Resurrection of Jesus Christ. 261 We must know Christ as the source of Grace in order to know Adam as the source of sin. the Spirit-Paraclete, sent by the risen Christ, came to "convict the world concerning sin", 262 by revealing him who is its Redeemer.

The eternal origin of the Holy Spirit is Revealed in his mission in time. the Spirit is sent to the apostles and to the Church both by the Father in the name of the Son, and by the Son in person, once he had returned to the Father. 69 The sending of the person of the Spirit after Jesus' glorification 70 reveals in its fullness the mystery of the Holy Trinity.
