Periods of renewal in the Church are also intense moments of catechesis. In the great era of the Fathers of the Church, saintly bishops devoted an important part of their ministry to catechesis. St. Cyril of Jerusalem and St. John Chrysostom, St. Ambrose and St. Augustine, and many other Fathers wrote catechetical works that remain models for us. 11

Only when the hour has arrived for his glorification does Jesus promise the coming of the Holy Spirit, since his Death and Resurrection will fulfill the promise made to the Fathers. 116 The Spirit of truth, the other Paraclete, will be given by the Father in answer to Jesus' Prayer; he will be sent by the Father in Jesus' name; and Jesus will send him from the Father's side, since he comes from the Father. the Holy Spirit will come and we shall know him; he will be with us for ever; he will remain with us. the Spirit will teach us everything, remind us of all that Christ said to us and bear witness to him. the Holy Spirit will lead us into all truth and will glorify Christ. He will prove the world wrong about sin, righteousness, and judgment.

"Christ is the light of humanity; and it is, accordingly, the heart-felt desire of this sacred Council, being gathered together in the Holy Spirit, that, by proclaiming his Gospel to every creature, it may bring to all men that light of Christ which shines out visibly from the Church." 135 These words open the Second Vatican Council's Dogmatic Constitution on the Church. By choosing this starting point, the Council demonstrates that the article of Faith about the Church depends entirely on the articles concerning Christ Jesus. the Church has no other light than Christ's; according to a favorite image of the Church Fathers, the Church is like the moon, all its light reflected from the sun.

The article concerning the Church also depends entirely on the article about the Holy Spirit, which immediately precedes it. "Indeed, having shown that the Spirit is the source and giver of all holiness, we now confess that it is he who has endowed the Church with holiness." 136 The Church is, in a phrase used by the Fathers, the place "where the Spirit flourishes." 137

"Often, too, the Church is called the building of God. the Lord compared himself to the stone which the builders rejected, but which was made into the comer-stone. On this foundation the Church is built by the apostles and from it the Church receives solidity and unity. This edifice has many names to describe it: the house of God in which his family dwells; the household of God in the Spirit; the dwelling-place of God among men; and, especially, the holy temple. This temple, symbolized in places of worship built out of stone, is praised by the Fathers and, not without reason, is compared in the liturgy to the Holy City, the New Jerusalem. As living stones we here on earth are built into it. It is this holy city that is seen by John as it comes down out of heaven from God when the world is made anew, prepared like a bride adorned for her husband. 148

To reunite all his children, scattered and led astray by sin, the Father willed to call the whole of humanity together into his Son's Church. the Church is the place where humanity must rediscover its unity and Salvation. the Church is "the world reconciled." She is that bark which "in the full sail of the Lord's cross, by the breath of the Holy Spirit, navigates safely in this world." According to another image dear to the Church Fathers, she is prefigured by Noah's ark, which alone saves from the flood. 334

How are we to understand this affirmation, often repeated by the Church Fathers? 335 Re-formulated positively, it means that all Salvation comes from Christ the Head through the Church which is his Body:

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

"Adhering to the teaching of the Holy Scriptures, to the apostolic Traditions, and to the consensus . . . of the Fathers," we profess that "the sacraments of the new law were . . . all instituted by Jesus Christ our Lord." 31

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.

It is by the conversion of the bread and wine into Christ's body and blood that Christ becomes present in this sacrament. the Church Fathers strongly affirmed the Faith of the Church in the efficacy of the Word of Christ and of the action of the Holy Spirit to bring about this conversion. Thus St. John Chrysostom declares:

Interior repentance is a radical reorientation of our whole life, a return, a conversion to God with all our heart, an end of sin, a turning away from evil, with repugnance toward the evil actions we have committed. At the same time it entails the desire and resolution to change one's life, with hope in God's mercy and trust in the help of his grace. This conversion of heart is accompanied by a salutary pain and sadness which the Fathers called animi cruciatus (affliction of spirit) and compunctio cordis (repentance of heart). 24

The interior penance of the Christian can be expressed in many and various ways. Scripture and the Fathers insist above all on three forms, fasting, Prayer, and almsgiving, 31 which express conversion in relation to oneself, to God, and to others. Alongside the radical purification brought about by Baptism or martyrdom they cite as means of obtaining forgiveness of sins: effort at reconciliation with one's neighbor, tears of repentance, concern for the Salvation of one's neighbor, the intercession of the saints, and the practice of charity "which covers a multitude of sins." 32

Christ instituted the sacrament of Penance for all sinful members of his Church: above all for those who, since Baptism, have fallen into grave sin, and have thus lost their baptismal grace and wounded ecclesial communion. It is to them that the sacrament of Penance offers a new possibility to convert and to recover the grace of justification. the Fathers of the Church present this sacrament as "the second plank [of Salvation] after the shipwreck which is the loss of grace." 47

The Second Vatican Council "teaches . . . that the fullness of the sacrament of Holy Orders is conferred by episcopal consecration, that fullness namely which, both in the liturgical Tradition of the Church and the language of the Fathers of the Church, is called the high priesthood, the acme (summa) of the sacred ministry." 36

The division and numbering of the Commandments have varied in the course of history. the present catechism follows the division of the Commandments established by St. Augustine, which has become Traditional in the Catholic Church. It is also that of the Lutheran confessions. the Greek Fathers worked out a slightly different division, which is found in the Orthodox Churches and Reformed communities.

Many religious have consecrated their whole lives to Prayer. Hermits, monks, and nuns since the time of the desert Fathers have devoted their time to praising God and interceding for his people. the consecrated life cannot be sustained or spread without prayer; it is one of the living sources of contemplation and the spiritual life of the Church.

Prayer is the life of the new heart. It ought to animate us at every moment. But we tend to forget him who is our life and our all. This is why the Fathers of the spiritual life in the Deuteronomic and prophetic Traditions insist that prayer is a remembrance of God often awakened by the memory of the heart "We must remember God more often than we draw breath." 1 But we cannot pray "at all times" if we do not pray at specific times, consciously willing it These are the special times of Christian prayer, both in intensity and duration.

The Church, a communion living in the Faith of the apostles which she transmits, is the place where we know the Holy Spirit: - in the Scriptures he inspired; - in the Tradition, to which the Church Fathers are always timely witnesses; - in the Church's Magisterium, which he assists; - in the sacramental liturgy, through its words and symbols, in which the Holy Spirit puts us into communion with Christ; - in Prayer, wherein he intercedes for us; - in the charisms and ministries by which the Church is built up; - in the signs of apostolic and missionary life; - in the witness of saints through whom he manifests his holiness and continues the work of Salvation.

The truth of Jesus' divinity is confirmed by his Resurrection. He had said: "When you have lifted up the Son of man, then you will know that I am he." 523 The Resurrection of the crucified one shows that he was truly "I AM", the Son of God and God himself. So St. Paul could declare to the Jews: "What God promised to the Fathers, this he has fulfilled to us their children by raising Jesus; as also it is written in the second psalm, 'You are my Son, today I have begotten you.'" 524 Christ's Resurrection is closely linked to the Incarnation of God's Son, and is its fulfilment in accordance with God's eternal plan.

It is therefore no surprise that catechesis in the Church has again attracted attention in the wake of the Second Vatican Council, which Pope Paul Vl considered the great catechism of modern times. the General Catechetical Directory (1971) the sessions of the Synod of Bishops devoted to evangelization (1974) and catechesis (1977), the apostolic exhortations Evangelii nuntiandi (1975) and Catechesi tradendae (1979), attest to this. the Extraordinary Synod of Bishops in 1985 asked "that a catechism or compendium of all Catholic doctrine regarding both Faith and morals be composed" 13 The Holy Father, Pope John Paul II, made the Synod's wish his own, acknowledging that "this desire wholly corresponds to a real need of the universal Church and of the particular Churches." 14 He set in motion everything needed to carry out the Synod Fathers' wish.

This catechism aims at presenting an organic synthesis of the essential and fundamental contents of Catholic doctrine, as regards both Faith and morals, in the light of the Second Vatican Council and the whole of the Church's Tradition. Its principal sources are the Sacred Scriptures, the Fathers of the Church, the liturgy, and the Church's Magisterium. It is intended to serve "as a point of reference for the catechisms or compendia that are composed in the various countries". 15

"In many and various ways God spoke of old to our Fathers by the prophets, but in these last days he has spoken to us by a Son." 26 Christ, the Son of God made man, is the Father's one, perfect and unsurpassable Word. In him he has said everything; there will be no other word than this one. St. John of the Cross, among others, commented strikingly on Hebrews 1:1-2:

This living transmission, accomplished in the Holy Spirit, is called Tradition, since it is distinct from Sacred Scripture, though closely connected to it. Through Tradition, "the Church, in her doctrine, life and worship, perpetuates and transmits to every generation all that she herself is, all that she believes." 37 "The sayings of the holy Fathers are a witness to the life-giving presence of this Tradition, showing how its riches are poured out in the practice and life of the Church, in her belief and her Prayer." 38

2. Read the Scripture within "the living Tradition of the whole Church". According to a saying of the Fathers, Sacred Scripture is written principally in the Church's heart rather than in documents and records, for the Church carries in her Tradition the living memorial of God's Word, and it is the Holy Spirit who gives her the spiritual interpretation of the Scripture (". . . according to the spiritual meaning which the Spirit grants to the Church" 81 ).

"These three parts are distinct although connected with one another. According to a comparison often used by the Fathers, we call them articles. Indeed, just as in our bodily members there are certain articulations which distinguish and separate them, so too in this profession of Faith, the name "articles" has justly and rightly been given to the truths we must believe particularly and distinctly." 6 In accordance with an ancient Tradition, already attested to by St. Ambrose, it is also customary to reckon the articles of the Creed as twelve, thus symbolizing the fullness of the apostolic faith by the number of the apostles. 7

God calls Moses from the midst of a bush that burns without being consumed: "I am the God of your Father, the God of Abraham, the God of Isaac, and the God of Jacob." 9 God is the God of the Fathers, the One who had called and guided the patriarchs in their wanderings. He is the Faithful and compassionate God who remembers them and his promises; he comes to free their descendants from slavery. He is the God who, from beyond space and time, can do this and wills to do it, the God who will put his almighty power to work for this plan.

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.

During the first centuries the Church sought to clarify her Trinitarian Faith, both to deepen her own understanding of the faith and to defend it against the errors that were deforming it. This clarification was the work of the early councils, aided by the theological work of the Church Fathers and sustained by the Christian people's sense of the faith.

The Christian Tradition sees in this passage an announcement of the "New Adam" who, because he "became obedient unto death, even death on a cross", makes amends superabundantly for the disobedience, of Adam. 305 Furthermore many Fathers and Doctors of the Church have seen the woman announced in the "Proto-evangelium" as Mary, the mother of Christ, the "new Eve". Mary benefited first of all and uniquely from Christ's victory over sin: she was preserved from all stain of original sin and by a special grace of God committed no sin of any kind during her whole earthly life. 306

The Monophysites affirmed that the human nature had ceased to exist as such in Christ when the divine person of God's Son assumed it. Faced with this heresy, the fourth ecumenical council, at Chalcedon in 451, confessed: Following the holy Fathers, we unanimously teach and confess one and the same Son, our Lord Jesus Christ: the same perfect in divinity and perfect in humanity, the same truly God and truly man, composed of rational soul and body; consubstantial with the Father as to his divinity and consubstantial with us as to his humanity; "like us in all things but sin". He was begotten from the Father before all ages as to his divinity and in these last days, for us and for our Salvation, was born as to his humanity of the virgin Mary, the Mother of God. 91

The Fathers of the Eastern Tradition call the Mother of God "the All-Holy" (Panagia), and celebrate her as "free from any stain of sin, as though fashioned by the Holy Spirit and formed as a new creature". 138 By the grace of God Mary remained free of every personal sin her whole life long. "Let it be done to me according to your word. . ."

From the first formulations of her Faith, the Church has confessed that Jesus was conceived solely by the power of the Holy Spirit in the womb of the Virgin Mary, affirming also the corporeal aspect of this event: Jesus was conceived "by the Holy Spirit without human seed". 146 The Fathers see in the virginal conception the sign that it truly was the Son of God who came in a humanity like our own. Thus St. Ignatius of Antioch at the beginning of the second century says: You are firmly convinced about our Lord, who is truly of the race of David according to the flesh, Son of God according to the will and power of God, truly born of a virgin,. . . he was truly nailed to a tree for us in his flesh under Pontius Pilate. . . he truly suffered, as he is also truly risen. 147

Consequently, St. Peter can formulate the apostolic Faith in the divine plan of Salvation in this way: "You were ransomed from the futile ways inherited from your Fathers... with the precious blood of Christ, like that of a lamb without blemish or spot. He was destined before the foundation of the world but was made manifest at the end of the times for your sake." 402 Man's sins, following on original sin, are punishable by death. 403 By sending his own Son in the form of a slave, in the form of a fallen humanity, on account of sin, God "made him to be sin who knew no sin, so that in him we might become the righteousness of God." 404

"We bring you the good news that what God promised to the Fathers, this day he has fulfilled to us their children by raising Jesus." 488 The Resurrection of Jesus is the crowning truth of our Faith in Christ, a faith believed and lived as the central truth by the first Christian community; handed on as fundamental by Tradition; established by the documents of the New Testament; and preached as an essential part of the Paschal mystery along with the cross:

The Fathers contemplate the Resurrection from the perspective of the divine person of Christ who remained united to his soul and body, even when these were separated from each other by death: "By the unity of the divine nature, which remains present in each of the two components of man, these are reunited. For as death is produced by the separation of the human components, so Resurrection is achieved by the union of the two." 519

Meditation is above all a quest. the mind seeks to understand the why and how of the Christian life, in order to adhere and respond to what the Lord is asking. the required attentiveness is difficult to sustain. We are usually helped by books, and Christians do not want for them: the Sacred Scriptures, particularly the Gospels, holy icons, liturgical texts of the day or season, writings of the spiritual Fathers, works of spirituality, the great book of creation, and that of history the page on which the "today" of God is written.
