Magisterium, Second Vatican Council

2. In His goodness and wisdom God chose to reveal Himself and to make known to us the hidden purpose of His will (see Eph. 1:9) by which through Christ, the Word made flesh, man might in the Holy Spirit have access to the Father and come to share in the divine nature (see Eph. 2:18; 2 Peter 1:4). Through this revelation, therefore, the invisible God (see Col. 1:15; 1 Tim. 1:17) out of the abundance of His love speaks to men as friends (see Ex. 33:11; John 15:14-15) and lives among them (see Bar. 3:38), so that He may invite and take them into fellowship with Himself. This plan of revelation is realized by deeds and words having an inner unity: the deeds wrought by God in the history of salvation manifest and confirm the teaching and realities signified by the words, while the words proclaim the deeds and clarify the mystery contained in them. By this revelation then, the deepest truth about God and the salvation of man shines out for our sake in Christ, who is both the mediator and the fullness of all revelation [2].

3. God, who through the Word creates all things (see John 1:3) and keeps them in existence, gives men an enduring witness to Himself in created realities (see Rom. 1:19-20). Planning to make known the way of heavenly salvation, He went further and from the start manifested Himself to our first parents. Then after their fall His promise of redemption aroused in them the hope of being saved (see Gen. 3:15) and from that time on He ceaselessly kept the human race in His care, to give eternal life to those who perseveringly do good in search of salvation (see Rom. 2:6-7). Then, at the time He had appointed He called Abraham in order make of him a great nation (see Gen. 12:2). Through the patriarchs, and after them through Moses and the prophets, He taught this people to acknowledge Himself the one living and true God, provident father and just judge, and to wait for the Saviour promised by Him, and in this manner prepared the way for the Gospel down through the centuries.

4. Then, after speaking in many and varied ways through the prophets, "now at last in these days God has spoken to us in His Son" (Heb. 1:1- 2). For He sent His Son, the eternal Word, who enlightens all men, so that He might dwell among men and tell them of the innermost being of God (see John 1:1-18). Jesus Christ, therefore, the Word made flesh, was sent as "a man to men" [3]. He "speaks the words of God" (John 3:34), and completes the work of salvation which His Father gave to Him to do (see John 5:36, 17:4). To see Jesus is to see His Father (see John 14:9). For this reason Jesus perfected revelation by fulfilling it through his whole work of making Himself present and manifesting Himself: through His words and deeds, His signs and wonders, but especially through His death and glorious resurrection from the dead and final sending of the Spirit of truth. Moreover He confirmed with divine testimony what revelation proclaimed, that God is with us to free us from the darkness of sin and death, and to raise us up to life eternal.

The Christian dispensation, therefore, as the new and definitive covenant, will never pass away and we now await no further new public revelation before the glorious manifestation of our Lord Jesus Christ (see 1 Tim. 6:14 and Tit. 2:13).

5. "The obedience of faith" (Rom. 16:26; see Rom. 1:5; 2 Cor. 10:5-6) "is to be given to God who reveals, an obedience by which man commits his whole self freely to God, offering the full submission of intellect and will to God who reveals" [4], and freely assenting to the truth revealed by Him. TO make this act of faith, the grace of God and the interior help of the Holy Spirit must precede and assist, moving the heart and turning it to God, opening the eyes of the mind and giving "joy and ease to everyone in assenting to the truth and believing it" [5]. To bring about an ever deeper understanding of revelation the same Holy Spirit constantly brings faith to completion by His gifts.

6. Through divine revelation, God chose to show forth and communicate Himself and the eternal decisions of His will regarding the salvation of men. That is to say, He chose to share with them those divine treasures which totally transcend the understanding of the human mind [6]. As a sacred synod has affirmed, "God, the beginning and end of all things, can be known with certainty from created reality by the light of human reason" (See Rom. 1:20); but it teaches that it is through His revelation "that those religious truths which are by their nature accessible to human reason can be known by all men with ease, with solid certitude and with no trace of error, even in this present state of the human race" [7].
