Jesus "was praying at a certain place, and when he ceased, one of his Disciples said to him, 'Lord, teach us to pray, as John taught his disciples.'" 1 In response to this request the Lord entrusts to his disciples and to his Church the fundamental Christian Prayer. St. Luke presents a brief text of five petitions, 2 while St. Matthew gives a more developed version of seven petitions. 3 The liturgical tradition of the Church has retained St. Matthew's text:

In the Old Testament the Prophets announced that the Spirit of the Lord would rest on the hoped-for Messiah for his saving mission. 90 The descent of the Holy Spirit on Jesus at his Baptism by John was the sign that this was he who was to come, the Messiah, the Son of God. 91 He was conceived of the Holy Spirit; his whole life and his whole mission are carried out in total communion with the Holy Spirit whom the Father gives him "without measure." 92

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

All the Old Covenant prefigurations find their fulfillment in Christ Jesus. He begins his public life after having himself baptized by St. John the Baptist in the Jordan. 17 After his resurrection Christ gives this mission to his apostles: "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." 18

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 unity of Christ and the Church, head and members of one Body, also implies the distinction of the two within a perSonal relationship. This aspect is often expressed by the image of bridegroom and bride. the theme of Christ as Bridegroom of the Church was prepared for by the Prophets and announced by John the Baptist. 234 The Lord referred to himself as the "bridegroom." 235 The Apostle speaks of the whole Church and of each of the faithful, members of his Body, as a bride "betrothed" to Christ the Lord so as to become but one spirit with him. 236 The Church is the spotless bride of the spotless Lamb. 237 "Christ Loved the Church and gave himself up for her, that he might sanctify her." 238 He has joined her with himself in an everlasting covenant and never stops caring for her as for his own body: 239

"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

Finally, with John the Baptist, the Holy Spirit begins the restoration to man of "the divine likeness," prefiguring what he would achieve with and in Christ. John's Baptism was for repentance; baptism in water and the Spirit will be a new birth. 100

John the Baptist is "more than a prophet." 94 In him, the Holy Spirit concludes his speaking through the Prophets. John completes the cycle of prophets begun by Elijah. 95 He proclaims the imminence of the consolation of Israel; he is the "voice" of the Consoler who is coming. 96 As the Spirit of truth will also do, John "came to bear witness to the light." 97 In John's sight, the Spirit thus brings to completion the careful search of the prophets and fulfills the longing of the angels. 98 "He on whom you see the Spirit descend and remain, this is he who baptizes with the Holy Spirit. and I have seen and have borne witness that this is the Son of God.... Behold, the Lamb of God." 99

John is "Elijah (who) must come." 92 The fire of the Spirit dwells in him and makes him the forerunner of the coming Lord. In John, the precursor, the Holy Spirit completes the work of "[making] ready a people prepared for the Lord." 93

The three synoptic Gospels and St. Paul have handed on to us the account of the institution of the Eucharist; St. John, for his part, reports the words of Jesus in the synagogue of Capernaum that prepare for the institution of the Eucharist: Christ calls himself the bread of life, come down from heaven. 163

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:

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.

St. Luke in his gospel often expresses wonder and praise at the marvels of Christ and in his Acts of the Apostles stresses them as actions of the Holy Spirit: the community of Jerusalem, the invalid healed by Peter and John, the crowd that gives glory to God for that, and the pagans of Pisidia who "were glad and glorified the word of God." 123

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

St. John distinguishes three kinds of covetousness or concupiscence: lust of the flesh, lust of the eyes, and pride of life. 300 In the Catholic catechetical tradition, the ninth commandment forbids carnal concupiscence; the tenth forbids coveting another's goods.

St. John Chrysostom vigorously recalls this: "Not to enable the poor to share in our goods is to steal from them and deprive them of life. the goods we possess are not ours, but theirs." 238 "The demands of justice must be satisfied first of all; that which is already due in justice is not to be offered as a gift of charity": 239

Vices can be classified according to the virtues they oppose, or also be linked to the capital sins which Christian experience has distinguished, following St. John Cassian and St. Gregory the Great. They are called "capital" because they engender other sins, other vices. 138 They are pride, avarice, envy, wrath, lust, gluttony, and sloth or acedia.

"YOU were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and in the Spirit of our God." 9 One must appreciate the magnitude of the gift God has given us in the sacraments of Christian initiation in order to grasp the degree to which sin is excluded for him who has "put on Christ." 10 But the apostle John also says: "If we say we have no sin, we deceive ourselves, and the truth is not in us." 11 and the Lord himself taught us to pray: "Forgive us our trespasses," 12 linking our forgiveness of one another's offenses to the forgiveness of our sins that God will grant us.

Before so great a sacrament, the faithful can only echo humbly and with ardent faith the words of the Centurion: "Domine, non sum dignus ut intres sub tectum meum, sed tantum dic verbo, et sanabitur anima mea" ("Lord, I am not worthy that you should enter under my roof, but only say the word and my soul will be healed."). 217 and in the Divine Liturgy of St. John Chrysostom the faithful pray in the same spirit:

"There was a man sent from God, whose name was John." 89 John was "filled with the Holy Spirit even from his mother's womb" 90 by Christ himself, whom the Virgin Mary had just conceived by the Holy Spirit. Mary's visitation to Elizabeth thus became a visit from God to his people. 91

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 Church thus confesses that Jesus is inseparably true God and true man. He is truly the Son of God who, without ceasing to be God and Lord, became a man and our brother: "What he was, he remained and what he was not, he assumed", sings the Roman Liturgy. 95 and the liturgy of St. John Chrysostom proclaims and sings: "O only-begotten Son and Word of God, immortal being, you who deigned for our salvation to become incarnate of the holy Mother of God and ever-virgin Mary, you who without change became man and were crucified, O Christ our God, you who by your death have crushed death, you who are one of the Holy Trinity, glorified with the Father and the Holy Spirit, save us!" 96

Taking up St. John's expression, "The Word became flesh", 82 The Church calls "Incarnation" the fact that the Son of God assumed a human nature in order to accomplish our salvation in it. In a hymn cited by St. Paul, the Church sings the mystery of the Incarnation:

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

The consequences of original sin and of all men's perSonal sins put the world as a whole in the sinful condition aptly described in St. John's expression, "the sin of the world". 300 This expression can also refer to the negative influence exerted on people by communal situations and social structures that are the fruit of men's sins. 301

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.

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

Faced with God's fascinating and mysterious presence, man discovers his own insignificance. Before the burning bush, Moses takes off his sandals and veils his face in the presence of God's holiness. 13 Before the glory of the thrice-holy God, Isaiah cries out: "Woe is me! I am lost; for I am a man of unclean lips." 14 Before the divine signs wrought by Jesus, Peter exclaims: "Depart from me, for I am a sinful man, O Lord." 15 But because God is holy, he can forgive the man who realizes that he is a sinner before him: "I will not execute my fierce anger. . . for I am God and not man, the Holy One in your midst." 16 The apostle John says likewise: "We shall. . . reassure our hearts before him whenever our hearts condemn us; for God is greater than our hearts, and he knows everything." 17

"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:

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.

The Father's only Son, conceived as man in the womb of the Virgin Mary, is "Christ", that is to say, anointed by the Holy Spirit, from the beginning of his human existence, though the manifestation of this fact takes place only progressively: to the shepherds, to the magi, to John the Baptist, to the Disciples. 123 Thus the whole life of Jesus Christ will make manifest "how God anointed Jesus of Nazareth with the Holy Spirit and with power." 124

St. John the Baptist is the Lord's immediate precursor or forerunner, sent to prepare his way. 196 "Prophet of the Most High", John surpasses all the Prophets, of whom he is the last. 197 He inaugurates the Gospel, already from his mother's womb welcomes the coming of Christ, and rejoices in being "the friend of the bridegroom", whom he points out as "the Lamb of God, who takes away the sin of the world". 198 Going before Jesus "in the spirit and power of Elijah", John bears witness to Christ in his preaching, by his Baptism of conversion, and through his martyrdom. 199

Jesus' public life begins with his Baptism by John in the Jordan. 228 John preaches "a baptism of repentance for the forgiveness of sins". 229 A crowd of sinners 230 - tax collectors and soldiers, Pharisees and Sadducees, and prostitutes - come to be baptized by him. "Then Jesus appears." the Baptist hesitates, but Jesus insists and receives baptism. Then the Holy Spirit, in the form of a dove, comes upon Jesus and a voice from heaven proclaims, "This is my beLoved Son." 231 This is the manifestation ("Epiphany") of Jesus as Messiah of Israel and Son of God.

Fire. While water signifies birth and the fruitfulness of life given in the Holy Spirit, fire symbolizes the transforming energy of the Holy Spirit's actions. the Prayer of the prophet Elijah, who "arose like fire" and whose "word burned like a torch," brought down fire from heaven on the sacrifice on Mount Carmel. 37 This event was a "figure" of the fire of the Holy Spirit, who transforms what he touches. John the Baptist, who goes "before [the Lord] in the spirit and power of Elijah," proclaims Christ as the one who "will baptize you with the Holy Spirit and with fire." 38 Jesus will say of the Spirit: "I came to cast fire upon the earth; and would that it were already kindled!" 39 In the form of tongues "as of fire," the Holy Spirit rests on the Disciples on the morning of Pentecost and fills them with himself 40 The spiritual tradition has retained this symbolism of fire as one of the most expressive images of the Holy Spirit's actions. 41 "Do not quench the Spirit." 42

Following in the steps of the Prophets and John the Baptist, Jesus announced the judgement of the Last Day in his preaching. 581 Then will the conduct of each one and the secrets of hearts be brought to light. 582 Then will the culpable unbelief that counted the offer of God's grace as nothing be condemned. 583 Our attitude to our neighbour will disclose acceptance or refusal of grace and divine Love. 584 On the Last Day Jesus will say: "Truly I say to you, as you did it to one of the least of these my brethren, you did it to me." 585

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

Among the religious authorities of Jerusalem, not only were the Pharisee Nicodemus and the prominent Joseph of Arimathea both secret Disciples of Jesus, but there was also long-standing dissension about him, so much so that St. John says of these authorities on the very eve of Christ's Passion, "many.. . believed in him", though very imperfectly. 378 This is not surprising, if one recalls that on the day after Pentecost "a great many of the priests were obedient to the faith" and "some believers. . . belonged to the party of the Pharisees", to the point that St. James could tell St. Paul, "How many thousands there are among the Jews of those who have believed; and they are all zealous for the Law." 379

Many of Jesus' deeds and words constituted a "sign of contradiction", 321 but more so for the religious authorities in Jerusalem, whom the Gospel according to John often calls simply "the Jews", 322 than for the ordinary People of God. 323 To be sure, Christ's relations with the Pharisees were not exclusively polemical. Some Pharisees warn him of the danger he was courting; 324 Jesus praises some of them, like the scribe of Mark 12:34, and dines several times at their homes. 325 Jesus endorses some of the teachings imparted by this religious elite of God's people: the resurrection of the dead, 326 certain forms of piety (almsgiving, fasting and Prayer), 327 The custom of addressing God as Father, and the centrality of the commandment to Love God and neighbour. 328

From the day Peter confessed that Jesus is the Christ, the Son of the living God, the Master "began to show his Disciples that he must go to Jerusalem and suffer many things. . . and be killed, and on the third day be raised." 290 Peter scorns this prediction, nor do the others understand it any better than he. 291 In this context the mysterious episode of Jesus' Transfiguration takes place on a high mountain, 292 before three witnesses chosen by himself: Peter, James and John. Jesus' face and clothes become dazzling with light, and Moses and Elijah appear, speaking "of his departure, which he was to accomplish at Jerusalem". 293 A cloud covers him and a voice from heaven says: "This is my Son, my Chosen; listen to him!" 294

"Now after John was arrested, Jesus came into Galilee, preaching the gospel of God, and saying: 'The time is fulfilled, and the kingdom of God is at hand: repent, and believe in the gospel.'" 246 "To carry out the will of the Father Christ inaugurated the kingdom of heaven on earth." 247 Now the Father's will is "to raise up men to share in his own divine life". 248 He does this by gathering men around his Son Jesus Christ. This gathering is the Church, "on earth the seed and beginning of that kingdoms". 249

The Gospels speak of a time of solitude for Jesus in the desert immediately after his Baptism by John. Driven by the Spirit into the desert, Jesus remains there for forty days without eating; he lives among wild beasts, and angels minister to him. 241 At the end of this time Satan tempts him three times, seeking to compromise his filial attitude toward God. Jesus rebuffs these attacks, which recapitulate the temptations of Adam in Paradise and of Israel in the desert, and the devil leaves him "until an opportune time". 242

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
