So that this call should resound Throughout the world, Christ sent forth the apostles he had chosen, commissioning them to proclaim the gospel: "Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you; and lo, I am with you always, to the close of the age." 4 Strengthened by this mission, the apostles "went forth and preached everywhere, while the Lord worked with them and confirmed the message by the signs that attended it." 5

"At the Last Supper, on the night he was betrayed, our Savior instituted the Eucharistic sacrifice of his Body and Blood. This he did in order to perpetuate the sacrifice of the cross Throughout the ages until he should come again, and so to entrust to his beloved Spouse, the Church, a memorial of his death and resurrection: a sacrament of love, a sign of unity, a bond of charity, a Paschal banquet 'in which Christ is consumed, the mind is filled with grace, and a pledge of future glory is given to us.'" 133

The liturgy of the Eucharist unfolds according to a fundamental structure which has been preserved Throughout the centuries down to our own day. It displays two great parts that form a fundamental unity: - the gathering, the liturgy of the Word, with readings, homily and general intercessions; - the liturgy of the Eucharist, with the presentation of the bread and wine, the consecratory thanksgiving, and communion. The liturgy of the Word and liturgy of the Eucharist together form "one single act of worship"; 170 The Eucharistic table set for us is the table both of the Word of God and of the Body of the Lord. 171

Sacred Scripture begins with the creation of man and woman in the image and likeness of God and concludes with a vision of "the wedding-feast of the Lamb." 85 Scripture speaks Throughout of marriage and its "mystery," its institution and the meaning God has given it, its origin and its end, its various realizations throughout the History of Salvation, the difficulties arising from sin and its renewal "in the Lord" in the New Covenant of Christ and the Church. 86

Human interdependence is increasing and gradually spreading Throughout the world. the unity of the human family, embracing people who enjoy equal natural dignity, implies a universal common good. This good calls for an organization of the community of nations able to "provide for the different needs of men; this will involve the sphere of social life to which belong questions of food, hygiene, education, . . . and certain situations arising here and there, as for example . . . alleviating the miseries of refugees dispersed throughout the world, and assisting migrants and their families." 29

The virtue of solidarity goes beyond material goods. In spreading the spiritual goods of the Faith, the Church has promoted, and often opened new paths for, the development of temporal goods as well. and so Throughout the centuries has the Lord's saying been verified: "Seek first his kingdom and his righteousness, and all these things shall be yours as well": 47

The natural law is immutable and permanent Throughout the variations of History; 10 it subsists under the flux of ideas and customs and supports their progress. the rules that express it remain substantially valid. Even when it is rejected in its very principles, it cannot be destroyed or removed from the heart of man. It always rises again in the life of individuals and societies:

Through the grace of the sacrament of marriage, parents receive the responsibility and privilege of evangelizing their children. Parents should initiate their children at an early age into the mysteries of the Faith of which they are the "first heralds" for their children. They should associate them from their tenderest years with the life of the Church. 34 A wholesome family life can foster interior dispositions that are a genuine preparation for a living faith and remain a support for it Throughout one's life.

In the New Covenant, Prayer is the living relationship of the children of God with their Father who is good beyond measure, with his Son Jesus Christ and with the Holy Spirit. The grace of the Kingdom is "the union of the entire holy and royal Trinity . . . with the whole human spirit." 12 Thus, the life of prayer is the habit of being in the presence of the thrice-holy God and in communion with him. This communion of life is always possible because, through Baptism, we have already been united with Christ. 13 Prayer is Christian insofar as it is communion with Christ and extends Throughout the Church, which is his Body. Its dimensions are those of Christ's love. 14

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.

Certain constant characteristics appear Throughout the Psalms: simplicity and spontaneity of Prayer; the desire for God himself through and with all that is good in his creation; the distraught situation of the believer who, in his preferential love for the Lord, is exposed to a host of enemies and temptations, but who waits upon what the Faithful God will do, in the certitude of his love and in submission to his will. the prayer of the psalms is always sustained by praise; that is why the title of this collection as handed down to us is so fitting: "The Praises." Collected for the assembly's worship, the Psalter both sounds the call to prayer and sings the response to that call: Hallelu-Yah! (“Alleluia"), "Praise the Lord!"

Even more, what the Father gives us when our Prayer is united with that of Jesus is "another Counselor, to be with you for ever, even the Spirit of truth." 81 This new dimension of prayer and of its circumstances is displayed Throughout the farewell discourse. 82 In the Holy Spirit, Christian prayer is a communion of love with the Father, not only through Christ but also in him: "Hitherto you have asked nothing in my name; ask, and you will receive, that your joy may be full." 83

In the communion of saints, many and varied spiritualities have been developed Throughout the History of the Churches. the personal charism of some witnesses to God's love for men has been handed on, like "the spirit" of Elijah to Elisha and John the Baptist, so that their followers may have a share in this spirit. 43 A distinct spirituality can also arise at the point of convergence of liturgical and theological currents, bearing witness to the integration of the Faith into a particular human environment and its history. the different schools of Christian spirituality share in the living tradition of Prayer and are essential guides for the faithful. In their rich diversity they are refractions of the one pure light of the Holy Spirit.

"Holy Mother Church believes that she should celebrate the saving work of her divine Spouse in a sacred commemoration on certain days Throughout the course of the year. Once each week, on the day which she has called the Lord's Day, she keeps the memory of the Lord's resurrection. She also celebrates it once every year, together with his blessed Passion, at Easter, that most solemn of all feasts. In the course of the year, moreover, she unfolds the whole mystery of Christ .... Thus recalling the mysteries of the redemption, she opens up to the Faithful the riches of her Lord's powers and merits, so that these are in some way made present in every age; the faithful lay hold of them and are filled with saving grace." 33

Since, like all the Faithful, lay Christians are entrusted by God with the apostolate by virtue of their Baptism and Confirmation, they have the right and duty, individually or grouped in associations, to work so that the divine message of Salvation may be known and accepted by all men Throughout the earth. This duty is the more pressing when it is only through them that men can hear the Gospel and know Christ. Their activity in ecclesial communities is so necessary that, for the most part, the apostolate of the pastors cannot be fully effective without it. 433 The participation of lay people in Christ's priestly office

"The individual bishops are the visible source and foundation of unity in their own particular Churches." 408 As such, they "exercise their pastoral office over the portion of the People of God assigned to them," 409 assisted by priests and deacons. But, as a member of the episcopal college, each bishop shares in the concern for all the Churches. 410 The bishops exercise this care first "by ruling well their own Churches as portions of the universal Church," and so contributing "to the welfare of the whole Mystical Body, which, from another point of view, is a corporate body of Churches." 411 They extend it especially to the poor, 412 to those persecuted for the Faith, as well as to missionaries who are working Throughout the world.

In many ways, Throughout History down to the present day, men have given expression to their quest for God in their religious beliefs and behaviour: in their Prayers, sacrifices, rituals, meditations, and so forth. These forms of religious expression, despite the ambiguities they often bring with them, are so universal that one may well call man a religious being:

Throughout the ages, there have been so-called "private" revelations, some of which have been recognized by the authority of the Church. They do not belong, however, to the deposit of Faith. It is not their role to improve or complete Christ's definitive Revelation, but to help live more fully by it in a certain period of History. Guided by the Magisterium of the Church, the sensus fidelium knows how to discern and welcome in these revelations whatever constitutes an authentic call of Christ or his saints to the Church.

Throughout her life and until her last ordeal 15 when Jesus her son died on the cross, Mary's Faith never wavered. She never ceased to believe in the fulfilment of God's word. and so the Church venerates in Mary the purest realization of faith.

It is the Church that believes first, and so bears, nourishes and sustains my Faith. Everywhere, it is the Church that first confesses the Lord: "Throughout the world the holy Church acclaims you", as we sing in the hymn Te Deum; with her and in her, we are won over and brought to confess: "I believe", "We believe". It is through the Church that we receive faith and new life in Christ by Baptism. In the Rituale Romanum, the minister of Baptism asks the catechumen: "What do you ask of God's Church?" and the answer is: "Faith." "What does faith offer you?" "Eternal life." 54

"Indeed, the Church, though scattered Throughout the whole world, even to the ends of the earth, having received the Faith from the apostles and their disciples. . . guards [this preaching and faith] with care, as dwelling in but a single house, and similarly believes as if having but one soul and a single heart, and preaches, teaches and hands on this faith with a unanimous voice, as if possessing only one mouth." 59

"For though languages differ Throughout the world, the content of the Tradition is one and the same. the Churches established in Germany have no other Faith or Tradition, nor do those of the Iberians, nor those of the Celts, nor those of the East, of Egypt, of Libya, nor those established at the centre of the world. . ." 60 The Church's message "is true and solid, in which one and the same way of Salvation appears throughout the whole world." 61

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.

Angels have been present since creation and Throughout the History of Salvation, announcing this salvation from afar or near and serving the accomplishment of the divine plan: they closed the earthly paradise; protected Lot; saved Hagar and her child; stayed Abraham's hand; communicated the law by their ministry; led the People of God; announced births and callings; and assisted the prophets, just to cite a few examples. 194 Finally, the angel Gabriel announced the birth of the Precursor and that of Jesus himself. 195

Jesus ascribes this title to himself in a veiled way when he disputes with the Pharisees about the meaning of Psalm 110, but also in an explicit way when he addresses his apostles. 61 Throughout his public life, he demonstrated his divine sovereignty by works of power over nature, illnesses, demons, death and sin.

Throughout the Old Covenant the mission of many holy women prepared for that of Mary. At the very beginning there was Eve; despite her disobedience, she receives the promise of a posterity that will be victorious over the evil one, as well as the promise that she will be the mother of all the living. 128 By virtue of this promise, Sarah conceives a son in spite of her old age. 129 Against all human expectation God chooses those who were considered powerless and weak to show forth his Faithfulness to his promises: Hannah, the mother of Samuel; Deborah; Ruth; Judith and Esther; and many other women. 130 Mary "stands out among the poor and humble of the Lord, who confidently hope for and receive Salvation from him. After a long period of waiting the times are fulfilled in her, the exalted Daughter of Sion, and the new plan of salvation is established." 131

Christ's whole life is a mystery of redemption. Redemption comes to us above all through the blood of his cross, 179 but this mystery is at work Throughout Christ's entire life: -already in his Incarnation through which by becoming poor he enriches us with his poverty; 180 - in his hidden life which by his submission atones for our disobedience; 181 - in his word which purifies its hearers; 182 - in his healings and exorcisms by which "he took our infirmities and bore our diseases"; 183 - and in his Resurrection by which he justifies us. 184

Jesus' circumcision, on the eighth day after his birth, 209 is the sign of his incorporation into Abraham's descendants, into the people of the covenant. It is the sign of his submission to the Law 210 and his deputation to Israel's worship, in which he will participate Throughout his life. This sign prefigures that "circumcision of Christ" which is Baptism. 211

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."

In the New Testament, the word basileia can be translated by "kingship" (abstract noun), "kingdom" (concrete noun) or "reign" (action noun). the Kingdom of God lies ahead of us. It is brought near in the Word incarnate, it is proclaimed Throughout the whole Gospel, and it has come in Christ's death and Resurrection. the Kingdom of God has been coming since the Last Supper and, in the Eucharist, it is in our midst. the kingdom will come in glory when Christ hands it over to his Father:
