I. The Desire for God

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: (355, 170, 1718)
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.1
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 behavior: 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: (843, 2566, 2095-2109)
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.”2
29 But this “intimate and vital bond of man to God” (GS 19,1) can be forgotten, overlooked, or even explicitly rejected by man.3 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.4 (2123-2128, 398)
30 “Let the hearts of those who seek the LORD rejoice.”5 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. (2567, 845, 368)
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 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.6

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. (54, 337)
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.7
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?8
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,”9 can have its origin only in God. (2500, 1730, 1776, 1703, 366)
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.’”10 (199)
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. The proofs of God’s existence, however, can predispose one to faith and help one to see that faith is not opposed to reason. (50, 159)

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.”11 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.”12 (355)
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: (1960)
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.13
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.”14 (2036)

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. (851)
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.”15(213, 299)
42 God transcends all creatures. We must therefore continually purify our language of everything in it that is limited, image-bound or imperfect, if we are not to confuse our image of God — “the inexpressible, the incomprehensible, the invisible, the ungraspable” — with our human representations.16 Our human words always fall short of the mystery of God. (212, 300, 370)
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”;17 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.”18 (206)
________________________________________
IN BRIEF
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.
THE REVELATION OF GOD
________________________________________
I. God Reveals His “Plan of Loving Goodness”

51 “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 (2823, 1996)
52 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.
53 The divine plan of Revelation is realized simultaneously “by deeds and words which are intrinsically bound up with each other”4 and shed light on each other. It involves a specific divine pedagogy: God communicates himself to man gradually. He prepares him to welcome by stages the supernatural Revelation that is to culminate in the person and mission of the incarnate Word, Jesus Christ. (1953,1950)
St. Irenaeus of Lyons repeatedly speaks of this divine pedagogy using the image of God and man becoming accustomed to one another: The Word of God dwelt in man and became the Son of man in order to accustom man to perceive God and to accustom God to dwell in man, according to the Father’s pleasure.5

II. The Stages of Revelation

In the beginning God makes himself known
54 “God, who creates and conserves all things by his Word, provides men with constant evidence of himself in created realities. And furthermore, wishing to open up the way to heavenly salvation, he manifested himself to our first parents from the very beginning.”6 He invited them to intimate communion with himself and clothed them with resplendent grace and justice. (32, 374)
55 This revelation was not broken off by our first parents’ sin. “After the fall, [God] buoyed them up with the hope of salvation, by promising redemption; and he has never ceased to show his solicitude for the human race. For he wishes to give eternal life to all those who seek salvation by patience in well-doing.”7 (397, 410,761)
Even when he disobeyed you and lost your friendship you did not abandon him to the power of death…. Again and again you offered a covenant to man.8

The Covenant with Noah

56 After the unity of the human race was shattered by sin God at once sought to save humanity part by part. The covenant with Noah after the flood gives expression to the principle of the divine economy toward the “nations,” in other words, toward men grouped “in their lands, each with [its] own language, by their families, in their nations.”9 (401, 1219)
57 This state of division into many nations is at once cosmic, social, and religious. It is intended to limit the pride of fallen humanity,10 united only in its perverse ambition to forge its own unity as at Babel.11 But, because of sin, both polytheism and the idolatry of the nation and of its rulers constantly threaten this provisional economy with the perversion of paganism.12
58 The covenant with Noah remains in force during the times of the Gentiles, until the universal proclamation of the Gospel.13 The Bible venerates several great figures among the Gentiles: Abel the just, the king-priest Melchizedek—a figure of Christ—and the upright “Noah, Daniel, and Job.”14 Scripture thus expresses the heights of sanctity that can be reached by those who live according to the covenant of Noah, waiting for Christ to “gather into one the children of God who are scattered abroad.”15 (674, 2569)

God chooses Abraham

59 In order to gather together scattered humanity God calls Abram from his country, his kindred, and his father’s house,16 and makes him Abraham, that is, “the father of a multitude of nations.” “In you all the nations of the earth shall be blessed.”17 (145, 2570)
60 The people descended from Abraham would be the trustees of the promise made to the patriarchs, the chosen people, called to prepare for that day when God would gather all his children into the unity of the Church.18 They would be the root onto which the Gentiles would be grafted, once they came to believe.19(760, 762, 781)
61 The patriarchs, prophets, and certain other Old Testament figures have been and always will be honored as saints in all the Church’s liturgical traditions.

God forms his people Israel

62 After the patriarchs, God formed Israel as his people by freeing them from slavery in Egypt. He established with them the covenant of Mount Sinai and, through Moses, gave them his law so that they would recognize him and serve him as the one living and true God, the provident Father and just judge, and so that they would look for the promised Savior.20 (2060, 2574, 1961)
63 Israel is the priestly people of God, “called by the name of the LORD,” and “the first to hear the word of God,”21 the people of “elder brethren” in the faith of Abraham. (204, 2801, 839)
64 Through the prophets, God forms his people in the hope of salvation, in the expectation of a new and everlasting Covenant intended for all, to be written on their hearts.22 The prophets proclaim a radical redemption of the People of God, purification from all their infidelities, a salvation which will include all the nations.23 Above all, the poor and humble of the Lord will bear this hope. Such holy women as Sarah, Rebecca, Rachel, Miriam, Deborah, Hannah, Judith, and Esther kept alive the hope of Israel’s salvation. The purest figure among them is Mary.24 (711, 1965, 489)
III. Christ Jesus — “Mediator and Fullness of All Revelation”25
God has said everything in his Word
65 “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: (102, 516, 2717)
In giving us his Son, his only Word (for he possesses no other), he spoke everything to us at once in this sole Word—and he has no more to say… because what he spoke before to the prophets in parts, he has now spoken all at once by giving us the All Who is His Son. Any person questioning God or desiring some vision or revelation would be guilty not only of foolish behavior but also of offending him, by not fixing his eyes entirely upon Christ and by living with the desire for some other novelty.27

There will be no further Revelation

66 “The Christian economy, therefore, since it is the new and definitive Covenant, will never pass away; and no new public revelation is to be expected before the glorious manifestation of our Lord Jesus Christ.”28Yet even if Revelation is already complete, it has not been made completely explicit; it remains for Christian faith gradually to grasp its full significance over the course of the centuries. (94)
67 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. (84, 93)
Christian faith cannot accept “revelations” that claim to surpass or correct the Revelation of which Christ is the fulfillment, as is the case in certain non-Christian religions and also in certain recent sects which base themselves on such “revelations.”
________________________________________
IN BRIEF
68 By love, God has revealed himself and given himself to man. He has thus provided the definitive, superabundant answer to the questions that man asks himself about the meaning and purpose of his life.
69 God has revealed himself to man by gradually communicating his own mystery in deeds and in words.
70 Beyond the witness to himself that God gives in created things, he manifested himself to our first parents, spoke to them and, after the fall, promised them salvation (cf. Gen 3:15) and offered them his covenant.
71 God made an everlasting covenant with Noah and with all living beings (cf. Gen 9:16). It will remain in force as long as the world lasts.
72 God chose Abraham and made a covenant with him and his descendants. By the covenant God formed his people and revealed his law to them through Moses. Through the prophets, he prepared them to accept the salvation destined for all humanity.
73 God has revealed himself fully by sending his own Son, in whom he has established his covenant for ever. The Son is his Father’s definitive Word; so there will be no further Revelation after him.

THE TRANSMISSION OF DIVINE REVELATION
________________________________________
74 God “desires all men to be saved and to come to the knowledge of the truth”:29 that is, of Christ Jesus.30Christ must be proclaimed to all nations and individuals, so that this revelation may reach to the ends of the earth: (851)
God graciously arranged that the things he had once revealed for the salvation of all peoples should remain in their entirety, throughout the ages, and be transmitted to all generations.31

I. The Apostolic Tradition

75 “Christ the Lord, in whom the entire Revelation of the most high God is summed up, commanded the apostles to preach the Gospel, which had been promised beforehand by the prophets, and which he fulfilled in his own person and promulgated with his own lips. In preaching the Gospel, they were to communicate the gifts of God to all men. This Gospel was to be the source of all saving truth and moral discipline.”32 (171)
In the apostolic preaching…
76 In keeping with the Lord’s command, the Gospel was handed on in two ways:
— orally “by the apostles who handed on, by the spoken word of their preaching, by the example they gave, by the institutions they established, what they themselves had received—whether from the lips of Christ, from his way of life and his works, or whether they had learned it at the prompting of the Holy Spirit”;33
— in writing “by those apostles and other men associated with the apostles who, under the inspiration of the same Holy Spirit, committed the message of salvation to writing.”34
…continued in apostolic succession
77 “In order that the full and living Gospel might always be preserved in the Church the apostles left bishops as their successors. They gave them ‘their own position of teaching authority.’”35 Indeed, “the apostolic preaching, which is expressed in a special way in the inspired books, was to be preserved in a continuous line of succession until the end of time.”36 (861)
78 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 (174, 1124, 2651)
79 The Father’s self-communication made through his Word in the Holy Spirit, remains present and active in the Church: “God, who spoke in the past, continues to converse with the Spouse of his beloved Son. And the Holy Spirit, through whom the living voice of the Gospel rings out in the Church—and through her in the world—leads believers to the full truth, and makes the Word of Christ dwell in them in all its richness.”39

II. The Relationship Between Tradition and Sacred Scripture

One common source…
80 “Sacred Tradition and Sacred Scripture, then, are bound closely together and communicate one with the other. For both of them, flowing out from the same divine well-spring, come together in some fashion to form one thing and move towards the same goal.”40 Each of them makes present and fruitful in the Church the mystery of Christ, who promised to remain with his own “always, to the close of the age.”41
…two distinct modes of transmission
81 “Sacred Scripture is the speech of God as it is put down in writing under the breath of the Holy Spirit.”42(113)
“And [Holy] Tradition transmits in its entirety the Word of God which has been entrusted to the apostles by Christ the Lord and the Holy Spirit. It transmits it to the successors of the apostles so that, enlightened by the Spirit of truth, they may faithfully preserve, expound, and spread it abroad by their preaching.”43
82 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 honored with equal sentiments of devotion and reverence.”44

Apostolic Tradition and ecclesial traditions

83 The Tradition here in question comes from the apostles and hands on what they received from Jesus’ teaching and example and what they learned from the Holy Spirit. The first generation of Christians did not yet have a written New Testament, and the New Testament itself demonstrates the process of living Tradition. (1202, 2041, 2684)
Tradition is to be distinguished from the various theological, disciplinary, liturgical, or devotional traditions, born in the local churches over time. These are the particular forms, adapted to different places and times, in which the great Tradition is expressed. In the light of Tradition, these traditions can be retained, modified or even abandoned under the guidance of the Church’s magisterium.

III. The Interpretation of the Heritage of Faith

The heritage of faith entrusted to the whole of the Church
84 The apostles entrusted the “Sacred deposit” of the faith (the depositum fidei),45 contained in Sacred Scripture and Tradition, to the whole of the Church. “By adhering to [this heritage] the entire holy people, united to its pastors, remains always faithful to the teaching of the apostles, to the brotherhood, to the breaking of bread and the prayers. So, in maintaining, practicing, and professing the faith that has been handed on, there should be a remarkable harmony between the bishops and the faithful.”46 (857, 871, 2033)

The Magisterium of the Church

85 “The task of giving an authentic interpretation of the Word of God, whether in its written form or in the form of Tradition, has been entrusted to the living, teaching office of the Church alone. Its authority in this matter is exercised in the name of Jesus Christ.”47 This means that the task of interpretation has been entrusted to the bishops in communion with the successor of Peter, the Bishop of Rome. (888-892, 2032-2040)
86 “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 (688)
87 Mindful of Christ’s words to his apostles: “He who hears you, hears me,”49 the faithful receive with docility the teachings and directives that their pastors give them in different forms. (1548, 2037)

The dogmas of the faith

88 The Church’s Magisterium exercises the authority it holds from Christ to the fullest extent when it defines dogmas, that is, when it proposes, in a form obliging the Christian people to an irrevocable adherence of faith, truths contained in divine Revelation or also when it proposes, in a definitive way, truths having a necessary connection with these. (888-892, 2032-2040)
89 There is an organic connection between our spiritual life and the dogmas. Dogmas are lights along the path of faith; they illuminate it and make it secure. Conversely, if our life is upright, our intellect and heart will be open to welcome the light shed by the dogmas of faith.50 (2625)
90 The mutual connections between dogmas, and their coherence, can be found in the whole of the Revelation of the mystery of Christ.51 “In Catholic doctrine there exists an order or ‘hierarchy’ of truths, since they vary in their relation to the foundation of the Christian faith.”52 (114, 158, 234)

The supernatural sense of faith

91 All the faithful share in understanding and handing on revealed truth. They have received the anointing of the Holy Spirit, who instructs them53 and guides them into all truth.54 (737)
92 “The whole body of the faithful… cannot err in matters of belief. This characteristic is shown in the supernatural appreciation of faith (sensus fidei) on the part of the whole people, when, ‘from the bishops to the last of the faithful,’ they manifest a universal consent in matters of faith and morals.”55 (785)
93 “By this appreciation of the faith, aroused and sustained by the Spirit of truth, the People of God, guided by the sacred teaching authority (Magisterium),… receives… the faith, once for all delivered to the saints…. The People unfailingly adheres to this faith, penetrates it more deeply with right judgment, and applies it more fully in daily life.”56 (889)

Growth in understanding the faith

94 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: (66, 2651, 2038, 2518)
— “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
95 “It is clear therefore that, in the supremely wise arrangement of God, sacred Tradition, Sacred Scripture, and the Magisterium of the Church are so connected and associated that one of them cannot stand without the others. Working together, each in its own way, under the action of the one Holy Spirit, they all contribute effectively to the salvation of souls.”62
________________________________________
IN BRIEF
96 What Christ entrusted to the apostles, they in turn handed on by their preaching and writing, under the inspiration of the Holy Spirit, to all generations, until Christ returns in glory.
97 “Sacred Tradition and Sacred Scripture make up a single sacred deposit of the Word of God” (DV 10), in which, as in a mirror, the pilgrim Church contemplates God, the source of all her riches.
98 “The Church, in her doctrine, life, and worship, perpetuates and transmits to every generation all that she herself is, all that she believes” (DV 8 §1).
99 Thanks to its supernatural sense of faith, the People of God as a whole never ceases to welcome, to penetrate more deeply, and to live more fully from the gift of divine Revelation.
100 The task of interpreting the Word of God authentically has been entrusted solely to the Magisterium of the Church, that is, to the Pope and to the bishops in communion with him.

ARTICLE 3
SACRED SCRIPTURE
________________________________________
I. Christ—The Unique Word of Sacred Scripture

101 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
102 Through all the words of Sacred Scripture, God speaks only one single Word, his one Utterance in whom he expresses himself completely:64 (65, 2763, 426-429)
You recall that one and the same Word of God extends throughout Scripture, that it is one and the same Utterance that resounds in the mouths of all the sacred writers, since he who was in the beginning God with God has no need of separate syllables; for he is not subject to time.65
103 For this reason, the Church has always venerated the Scriptures as she venerates the Lord’s Body. She never ceases to present to the faithful the bread of life, taken from the one table of God’s Word and Christ’s Body.66 (1100, 1184, 1378)
104 In Sacred Scripture, the Church constantly finds her nourishment and her strength, for she welcomes it not as a human word, “but as what it really is, the word of God.”67 “In the sacred books, the Father who is in heaven comes lovingly to meet his children, and talks with them.”68

II. Inspiration and Truth of Sacred Scripture

105 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
“For Holy Mother Church, relying on the faith of the apostolic age, accepts as sacred and canonical the books of the Old and the New Testaments, whole and entire, with all their parts, on the grounds that, written under the inspiration of the Holy Spirit, they have God as their author and have been handed on as such to the Church herself.”70
106 God inspired the human authors of the sacred books. “To compose the sacred books, God chose certain men who, all the while he employed them in this task, made full use of their own faculties and powers so that, though he acted in them and by them, it was as true authors that they consigned to writing whatever he wanted written, and no more.”71
107 The inspired books teach the truth. “Since therefore all that the inspired authors or sacred writers affirm should be regarded as affirmed by the Holy Spirit, we must acknowledge that the books of Scripture firmly, faithfully, and without error teach that truth which God, for the sake of our salvation, wished to see confided to the Sacred Scriptures.”72 (702)
108 Still, the Christian faith is not a “religion of the book.” Christianity is the religion of the “Word” of God, a word which is “not a written and mute word, but the Word which is incarnate and living.”73 If the Scriptures are not to remain a dead letter, Christ, the eternal Word of the living God, must, through the Holy Spirit, “open [our] minds to understand the Scriptures.”74

III. The Holy Spirit, Interpreter of Scripture

109 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
110 In order to discover the sacred authors’ intention, the reader must take into account the conditions of their time and culture, the literary genres in use at that time, and the modes of feeling, speaking, and narrating then current. “For the fact is that truth is differently presented and expressed in the various types of historical writing, in prophetical and poetical texts, and in other forms of literary expression.”76
111 But since Sacred Scripture is inspired, there is another and no less important principle of correct interpretation, without which Scripture would remain a dead letter. “Sacred Scripture must be read and interpreted in the light of the same Spirit by whom it was written.”77
The Second Vatican Council indicates three criteria for interpreting Scripture in accordance with the Spirit who inspired it.78
112 1. Be especially attentive “to the content and unity of the whole Scripture.” Different as the books which comprise it may be, Scripture is a unity by reason of the unity of God’s plan, of which Christ Jesus is the center and heart, open since his Passover.79 (128, 368)
The phrase “heart of Christ” can refer to Sacred Scripture, which makes known his heart, closed before the Passion, as the Scripture was obscure. But the Scripture has been opened since the Passion; since those who from then on have understood it, consider and discern in what way the prophecies must be interpreted.80
113 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). (81)
114 3. Be attentive to the analogy of faith.82 By “analogy of faith” we mean the coherence of the truths of faith among themselves and within the whole plan of Revelation. (90)

The senses of Scripture

115 According to an ancient tradition, one can distinguish between two senses of Scripture: the literal and the spiritual, the latter being subdivided into the allegorical, moral, and anagogical senses. The profound concordance of the four senses guarantees all its richness to the living reading of Scripture in the Church.
116 The literal sense is the meaning conveyed by the words of Scripture and discovered by exegesis, following the rules of sound interpretation: “All other senses of Sacred Scripture are based on the literal.”83 (110-114)
117 The spiritual sense. Thanks to the unity of God’s plan, not only the text of Scripture but also the realities and events about which it speaks can be signs. (1101)

1. The allegorical sense. We can acquire a more profound understanding of events by recognizing their significance in Christ; thus the crossing of the Red Sea is a sign or type of Christ’s victory and also of Christian Baptism.84
2. The moral sense. The events reported in Scripture ought to lead us to act justly. As St. Paul says, they were written “for our instruction.”85
3. The anagogical sense (Greek: anagoge, “leading”). We can view realities and events in terms of their eternal significance, leading us toward our true homeland: thus the Church on earth is a sign of the heavenly Jerusalem.86

118 A medieval couplet summarizes the significance of the four senses:
The Letter speaks of deeds; Allegory to faith;
The Moral how to act; Anagogy our destiny.87
119 “It is the task of exegetes to work, according to these rules, toward a better understanding and explanation of the meaning of Sacred Scripture in order that their research may help the Church to form a firmer judgment. For, of course, all that has been said about the manner of interpreting Scripture is ultimately subject to the judgment of the Church which exercises the divinely conferred commission and ministry of watching over and interpreting the Word of God.”88 (94, 113)
But I would not believe in the Gospel, had not the authority of the Catholic Church already moved me.89

IV. The Canon of Scripture

120 It was by the apostolic Tradition that the Church discerned which writings are to be included in the list of the sacred books.90 This complete list is called the canon of Scripture. It includes 46 books for the Old Testament (45 if we count Jeremiah and Lamentations as one) and 27 for the New.91 (1117)
The Old Testament: Genesis, Exodus, Leviticus, Numbers, Deuteronomy, Joshua, Judges, Ruth, 1 and 2 Samuel, 1 and 2 Kings, 1 and 2 Chronicles, Ezra and Nehemiah, Tobit, Judith, Esther, 1 and 2 Maccabees, Job, Psalms, Proverbs, Ecclesiastes, the Song of Songs, the Wisdom of Solomon, Sirach (Ecclesiasticus), Isaiah, Jeremiah, Lamentations, Baruch, Ezekiel, Daniel, Hosea, Joel, Amos, Obadiah, Jonah, Micah, Nahum, Habakkuk, Zephaniah, Haggai, Zechariah and Malachi.
The New Testament: the Gospels according to Matthew, Mark, Luke and John, the Acts of the Apostles, the Letters of St. Paul to the Romans, 1 and 2 Corinthians, Galatians, Ephesians, Philippians, Colossians, 1 and 2 Thessalonians, 1 and 2 Timothy, Titus, Philemon, the Letter to the Hebrews, the Letters of James, 1 and 2 Peter, 1, 2, and 3 John, and Jude, and Revelation (the Apocalypse).

The Old Testament

121 The Old Testament is an indispensable part of Sacred Scripture. Its books are divinely inspired and retain a permanent value,92 for the Old Covenant has never been revoked. (1093)
122 Indeed, “the economy of the Old Testament was deliberately so oriented that it should prepare for and declare in prophecy the coming of Christ, redeemer of all men.”93 “Even though they contain matters imperfect and provisional,”94 the books of the Old Testament bear witness to the whole divine pedagogy of God’s saving love: these writings “are a storehouse of sublime teaching on God and of sound wisdom on human life, as well as a wonderful treasury of prayers; in them, too, the mystery of our salvation is present in a hidden way.”95 (702, 763, 708, 2568)
123 Christians venerate the Old Testament as true Word of God. The Church has always vigorously opposed the idea of rejecting the Old Testament under the pretext that the New has rendered it void (Marcionism).

The New Testament

124 “The Word of God, which is the power of God for salvation to everyone who has faith, is set forth and displays its power in a most wonderful way in the writings of the New Testament”96 which hand on the ultimate truth of God’s Revelation. Their central object is Jesus Christ, God’s incarnate Son: his acts, teachings, Passion and glorification, and his Church’s beginnings under the Spirit’s guidance.97
125 The Gospels are the heart of all the Scriptures “because they are our principal source for the life and teaching of the Incarnate Word, our Savior.”98 (515)
126 We can distinguish three stages in the formation of the Gospels: (76)

1. The life and teaching of Jesus. The Church holds firmly that the four Gospels, “whose historicity she unhesitatingly affirms, faithfully hand on what Jesus, the Son of God, while he lived among men, really did and taught for their eternal salvation, until the day when he was taken up.”99
2. The oral tradition. “For, after the ascension of the Lord, the apostles handed on to their hearers what he had said and done, but with that fuller understanding which they, instructed by the glorious events of Christ and enlightened by the Spirit of truth, now enjoyed.”100
3. The written Gospels. “The sacred authors, in writing the four Gospels, selected certain of the many elements which had been handed on, either orally or already in written form; others they synthesized or explained with an eye to the situation of the churches, while sustaining the form of preaching, but always in such a fashion that they have told us the honest truth about Jesus.”101
127 The fourfold Gospel holds a unique place in the Church, as is evident both in the veneration which the liturgy accords it and in the surpassing attraction it has exercised on the saints at all times: (1154, 2705)
There is no doctrine which could be better, more precious and more splendid than the text of the Gospel. Behold and retain what our Lord and Master, Christ, has taught by his words and accomplished by his deeds.102
But above all it’s the Gospels that occupy my mind when I’m at prayer; my poor soul has so many needs, and yet this is the one thing needful. I’m always finding fresh lights there, hidden and enthralling meanings.103

The unity of the Old and New Testaments

128 The Church, as early as apostolic times,104 and then constantly in her Tradition, has illuminated the unity of the divine plan in the two Testaments through typology, which discerns in God’s works of the Old Covenant prefigurations of what he accomplished in the fullness of time in the person of his incarnate Son. (1094, 489)
129 Christians therefore read the Old Testament in the light of Christ crucified and risen. Such typological reading discloses the inexhaustible content of the Old Testament; but it must not make us forget that the Old Testament retains its own intrinsic value as Revelation reaffirmed by our Lord himself.105 Besides, the New Testament has to be read in the light of the Old. Early Christian catechesis made constant use of the Old Testament.106 As an old saying put it, the New Testament lies hidden in the Old and the Old Testament is unveiled in the New.107 (681, 2055, 1968)
130 Typology indicates the dynamic movement toward the fulfillment of the divine plan when “God [will] be everything to everyone.”108 Nor do the calling of the patriarchs and the exodus from Egypt, for example, lose their own value in God’s plan, from the mere fact that they were intermediate stages.

V. Sacred Scripture in the Life of the Church

131 “And such is the force and power of the Word of God that it can serve the Church as her support and vigor and the children of the Church as strength for their faith, food for the soul, and a pure and lasting font of spiritual life.”109 Hence “access to Sacred Scripture ought to be open wide to the Christian faithful.”110
132 “Therefore, the ‘study of the sacred page’ should be the very soul of sacred theology. The ministry of the Word, too—pastoral preaching, catechetics, and all forms of Christian instruction, among which the liturgical homily should hold pride of place—is healthily nourished and thrives in holiness through the Word of Scripture.”111 (94)
133 The Church “forcefully and specifically exhorts all the Christian faithful… to learn ‘the surpassing knowledge of Jesus Christ,’ by frequent reading of the divine Scriptures. ‘Ignorance of the Scriptures is ignorance of Christ.’”112 (2653, 1792)
