"FATHER,... this is eternal life, that they may know you, the only true God, and Jesus Christ whom you have sent."
"God our Saviour desires all men to be saved and to come to the knowledge of the truth."
"There is no other name under heaven given among men by which we must be saved" - than the name of JESUS.
I. The life of man - to know and love God
1 God, infinitely perfect and blessed in himself, in a plan of sheer goodness freely created man to make him share in his own blessed life. For this reason, at every time and in every place, God draws close to man. He calls man to seek him, to know him, to love him with all his strength. He calls together all men, scattered and divided by sin, into the unity of his family, the Church. To accomplish this, when the fullness of time had come, God sent his Son as Redeemer and Saviour. In his Son and through him, he invites men to become, in the Holy Spirit, his adopted children and thus heirs of his blessed life.
2 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." 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."
3 Those who with God's help have welcomed Christ's call and freely responded to it are urged on by love of Christ to proclaim the Good News everywhere in the world. This treasure, received from the apostles, has been faithfully guarded by their successors. All Christ's faithful are called to hand it on from generation to generation, by professing the faith, by living it in fraternal sharing, and by celebrating it in liturgy and prayer.
II. HANDING ON THE FAITH: CATECHESIS
4 Quite early on, the name catechesis was given to the totality of the Church's efforts to make disciples, to help men believe that Jesus is the Son of God so that believing they might have life in his name, and to educate and instruct them in this life, thus building up the body of Christ.
5 "Catechesis is an education in the faith of children, young people and adults which includes especially the teaching of Christian doctrine imparted, generally speaking, in an organic and systematic way, with a view to initiating the hearers into the fullness of Christian life."
6 While not being formally identified with them, catechesis is built on a certain number of elements of the Church's pastoral mission which have a catechetical aspect, that prepare for catechesis, or spring from it. They are: the initial proclamation of the Gospel or missionary preaching to arouse faith; examination of the reasons for belief; experience of Christian living; celebration of the sacraments; integration into the ecclesial community; and apostolic and missionary witness.
7 "Catechesis is intimately bound up with the whole of the Church's life. Not only her geographical extension and numerical increase, but even more her inner growth and correspondence with God's plan depend essentially on catechesis."
8 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.
9 "The ministry of catechesis draws ever fresh energy from the councils. The Council of Trent is a noteworthy example of this. It gave catechesis priority in its constitutions and decrees. It lies at the origin of the Roman Catechism, which is also known by the name of that council and which is a work of the first rank as a summary of Christian teaching. . " The Council of Trent initiated a remarkable organization of the Church's catechesis. Thanks to the work of holy bishops and theologians such as St. Peter Canisius, St. Charles Borromeo, St. Turibius of Mongrovejo or St. Robert Bellarmine, it occasioned the publication of numerous catechisms.
10 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" 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." He set in motion everything needed to carry out the Synod Fathers' wish.
III. THE AIM AND INTENDED READERSHIP OF THE CATECHISM
11 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".
12 This work is intended primarily for those responsible for catechesis: first of all the bishops, as teachers of the faith and pastors of the Church. It is offered to them as an instrument in fulfilling their responsibility of teaching the People of God. Through the bishops, it is addressed to redactors of catechisms, to priests, and to catechists. It will also be useful reading for all other Christian faithful.
IV. STRUCTURE OF THIS CATECHISM
13 The plan of this catechism is inspired by the great tradition of catechisms which build catechesis on four pillars: the baptismal profession of faith (the Creed), the sacraments of faith, the life of faith (the Commandments), and the prayer of the believer (the Lord's Prayer).

14 Those who belong to Christ through faith and Baptism must confess their baptismal faith before men. First therefore the Catechism expounds revelation, by which God addresses and gives himself to man, and the faith by which man responds to God (Section One). The profession of faith summarizes the gifts that God gives man: as the Author of all that is good; as Redeemer; and as Sanctifier. It develops these in the three chapters on our baptismal faith in the one God: the almighty Father, the Creator; his Son Jesus Christ, our Lord and Saviour; and the Holy Spirit, the Sanctifier, in the Holy Church (Section Two).

15 The second part of the Catechism explains how God's salvation, accomplished once for all through Christ Jesus and the Holy Spirit, is made present in the sacred actions of the Church's liturgy (Section One), especially in the seven sacraments (Section Two).
Error: Reference source not found
16 The third part of the Catechism deals with the final end of man created in the image of God: beatitude, and the ways of reaching it - through right conduct freely chosen, with the help of God's law and grace (Section One), and through conduct that fulfils the twofold commandment of charity, specified in God's Ten Commandments (Section Two).
Error: Reference source not found
17 The last part of the Catechism deals with the meaning and importance of prayer in the life of believers (Section One). It concludes with a brief commentary on the seven petitions of the Lord's Prayer (Section Two), for indeed we find in these the sum of all the good things which we must hope for, and which our heavenly Father wants to grant us.
V. PRACTICAL DIRECTIONS FOR USING THIS CATECHISM
18 This catechism is conceived as an organic presentation of the Catholic faith in its entirety. It should be seen therefore as a unified whole. Numerous cross-references in the margin of the text (numbers found at the end of a sentence referring to other paragraphs that deal with the same theme), as well as the analytical index at the end of the volume, allow the reader to view each theme in its relationship with the entirety of the faith.
19 The texts of Sacred Scripture are often not quoted word for word but are merely indicated by a reference (cf.). For a deeper understanding of such passages, the reader should refer to the Scriptural texts themselves. Such Biblical references are a valuable working-tool in catechesis.
20 The use of small print in certain passages indicates observations of an historical or apologetic nature, or supplementary doctrinal explanations.
21 The quotations, also in small print, from patristic, liturgical, magisterial or hagiographical sources, are intended to enrich the doctrinal presentations. These texts have often been chosen with a view to direct catechetical use.
22 At the end of each thematic unit, a series of brief texts in small italics sums up the essentials of that unit's teaching in condensed formulae. These "IN BRIEF" summaries may suggest to local catechists brief summary formulae that could be memorized.
VI. NECESSARY ADAPTATIONS
23 The Catechism emphasizes the exposition of doctrine. It seeks to help deepen understanding of faith. In this way it is oriented towards the maturing of that faith, its putting down roots in personal life, and its shining forth in personal conduct.
24 By design, this Catechism does not set out to provide the adaptation of doctrinal presentations and catechetical methods required by the differences of culture, age, spiritual maturity, and social and ecclesial condition among all those to whom it is addressed. Such indispensable adaptations are the responsibility of particular catechisms and, even more, of those who instruct the faithful:
Whoever teaches must become "all things to all men" (I Cor 9:22), to win everyone to Christ. . . Above all, teachers must not imagine that a single kind of soul has been entrusted to them, and that consequently it is lawful to teach and form equally all the faithful in true piety with one and the same method! Let them realize that some are in Christ as newborn babes, others as adolescents, and still others as adults in full command of their powers.... Those who are called to the ministry of preaching must suit their words to the maturity and understanding of their hearers, as they hand on the teaching of the mysteries of faith and the rules of moral conduct.
Above all - Charity
25 To conclude this Prologue, it is fitting to recall this pastoral principle stated by the Roman Catechism:
The whole concern of doctrine and its teaching must be directed to the love that never ends. Whether something is proposed for belief, for hope or for action, the love of our Lord must always be made accessible, so that anyone can see that all the works of perfect Christian virtue spring from love and have no other objective than to arrive at love.

THE PROFESSION OF FAITH
"I BELIEVE" - "WE BELIEVE"
26 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).
27 The desire for God is written in the human heart, because man is created by God and for God; and God never ceases to draw man to himself. Only in God will he find the truth and happiness he never stops searching for:
The dignity of man rests above all on the fact that he is called to communion with God. This invitation to converse with God is addressed to man as soon as he comes into being. For if man exists it is because God has created him through love, and through love continues to hold him in existence. He cannot live fully according to truth unless he freely acknowledges that love and entrusts himself to his creator.
28 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:
From one ancestor [God] made all nations to inhabit the whole earth, and he allotted the times of their existence and the boundaries of the places where they would live, so that they would search for God and perhaps grope for him and find him - though indeed he is not far from each one of us. For "in him we live and move and have our being."
29 But this "intimate and vital bond of man to God" (GS 19 # 1) can be forgotten, overlooked, or even explicitly rejected by man. Such attitudes can have different causes: revolt against evil in the world; religious ignorance or indifference; the cares and riches of this world; the scandal of bad example on the part of believers; currents of thought hostile to religion; finally, that attitude of sinful man which makes him hide from God out of fear and flee his call.
30 "Let the hearts of those who seek the LORD rejoice." Although man can forget God or reject him, He never ceases to call every man to seek him, so as to find life and happiness. But this search for God demands of man every effort of intellect, a sound will, "an upright heart", as well as the witness of others who teach him to seek God.
You are great, O Lord, and greatly to be praised: great is your power and your wisdom is without measure. And man, so small a part of your creation, wants to praise you: this man, though clothed with mortality and bearing the evidence of sin and the proof that you withstand the proud. Despite everything, man, though but a small a part of your creation, wants to praise you. You yourself encourage him to delight in your praise, for you have made us for yourself, and our heart is restless until it rests in you.
II. WAYS OF COMING TO KNOW GOD
31 Created in God's image and called to know and love him, the person who seeks God discovers certain ways of coming to know him. These are also called proofs for the existence of God, not in the sense of proofs in the natural sciences, but rather in the sense of "converging and convincing arguments", which allow us to attain certainty about the truth. These "ways" of approaching God from creation have a twofold point of departure: the physical world, and the human person.
32 The world: starting from movement, becoming, contingency, and the world's order and beauty, one can come to a knowledge of God as the origin and the end of the universe.
As St. Paul says of the Gentiles: For what can be known about God is plain to them, because God has shown it to them. Ever since the creation of the world his invisible nature, namely, his eternal power and deity, has been clearly perceived in the things that have been made.
And St. Augustine issues this challenge: Question the beauty of the earth, question the beauty of the sea, question the beauty of the air distending and diffusing itself, question the beauty of the sky. . . question all these realities. All respond: "See, we are beautiful." Their beauty is a profession [confessio]. These beauties are subject to change. Who made them if not the Beautiful One [Pulcher] who is not subject to change?
33 The human person: with his openness to truth and beauty, his sense of moral goodness, his freedom and the voice of his conscience, with his longings for the infinite and for happiness, man questions himself about God's existence. In all this he discerns signs of his spiritual soul. The soul, the "seed of eternity we bear in ourselves, irreducible to the merely material", can have its origin only in God.
34 The world, and man, attest that they contain within themselves neither their first principle nor their final end, but rather that they participate in Being itself, which alone is without origin or end. Thus, in different ways, man can come to know that there exists a reality which is the first cause and final end of all things, a reality "that everyone calls God".
35 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.
III. THE KNOWLEDGE OF GOD ACCORDING TO THE CHURCH
36 "Our holy mother, the Church, holds and teaches that God, the first principle and last end of all things, can be known with certainty from the created world by the natural light of human reason." Without this capacity, man would not be able to welcome God's revelation. Man has this capacity because he is created "in the image of God".
37 In the historical conditions in which he finds himself, however, man experiences many difficulties in coming to know God by the light of reason alone:
Though human reason is, strictly speaking, truly capable by its own natural power and light of attaining to a true and certain knowledge of the one personal God, who watches over and controls the world by his providence, and of the natural law written in our hearts by the Creator; yet there are many obstacles which prevent reason from the effective and fruitful use of this inborn faculty. For the truths that concern the relations between God and man wholly transcend the visible order of things, and, if they are translated into human action and influence it, they call for self-surrender and abnegation. The human mind, in its turn, is hampered in the attaining of such truths, not only by the impact of the senses and the imagination, but also by disordered appetites which are the consequences of original sin. So it happens that men in such matters easily persuade themselves that what they would not like to be true is false or at least doubtful.
38 This is why man stands in need of being enlightened by God's revelation, not only about those things that exceed his understanding, but also "about those religious and moral truths which of themselves are not beyond the grasp of human reason, so that even in the present condition of the human race, they can be known by all men with ease, with firm certainty and with no admixture of error". 
IV. HOW CAN WE SPEAK ABOUT GOD?
39 In defending the ability of human reason to know God, the Church is expressing her confidence in the possibility of speaking about him to all men and with all men, and therefore of dialogue with other religions, with philosophy and science, as well as with unbelievers and atheists.
40 Since our knowledge of God is limited, our language about him is equally so. We can name God only by taking creatures as our starting point, and in accordance with our limited human ways of knowing and thinking.
41 All creatures bear a certain resemblance to God, most especially man, created in the image and likeness of God. The manifold perfections of creatures - their truth, their goodness, their beauty all reflect the infinite perfection of God. Consequently we can name God by taking his creatures" perfections as our starting point, "for from the greatness and beauty of created things comes a corresponding perception of their Creator".
42 God transcends all creatures. We must therefore continually purify our language of everything in it that is limited, imagebound or imperfect, if we are not to confuse our image of God--"the inexpressible, the incomprehensible, the invisible, the ungraspable"--with our human representations. Our human words always fall short of the mystery of God.
43 Admittedly, in speaking about God like this, our language is using human modes of expression; nevertheless it really does attain to God himself, though unable to express him in his infinite simplicity. Likewise, we must recall that "between Creator and creature no similitude can be expressed without implying an even greater dissimilitude"; and that "concerning God, we cannot grasp what he is, but only what he is not, and how other beings stand in relation to him."
44 Man is by nature and vocation a religious being. Coming from God, going toward God, man lives a fully human life only if he freely lives by his bond with God.
45 Man is made to live in communion with God in whom he finds happiness: When I am completely united to you, there will be no more sorrow or trials; entirely full of you, my life will be complete (St. Augustine, Conf. 10, 28, 39: PL 32, 795}.
46 When he listens to the message of creation and to the voice of conscience, man can arrive at certainty about the existence of God, the cause and the end of everything.
47 The Church teaches that the one true God, our Creator and Lord, can be known with certainty from his works, by the natural light of human reason (cf. Vatican Council I, can. 2 # 1: DS 3026),
48 We really can name God, starting from the manifold perfections of his creatures, which are likenesses of the infinitely perfect God, even if our limited language cannot exhaust the mystery.
49 Without the Creator, the creature vanishes (GS 36). This is the reason why believers know that the love of Christ urges them to bring the light of the living God to those who do not know him or who reject him.
