Today, we finish up Chapter 1 of the Dogmatic Constitution on Divine Revelation with Dei Verbum 4-6.
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” (Epistle to Diognetus, c. VII, 4: Funk, Apostolic Fathers, I, p. 403). He “speaks the words of God” (John 3:34), and completes the work of salvation which His Father gave Him to do (see John 5:36; John 17:4). To see Jesus is to see His Father (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. 13:26; see 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” (First Vatican Council, Dogmatic Constitution on the Catholic Faith, Chap. 3, “On Faith:” Denzinger 1789 ), 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” (Second Council of Orange, Canon 7: Denzinger 180 ; First Vatican Council, loc. cit.: Denzinger 1791 ). 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 (First Vatican Council, Dogmatic Constitution on the Catholic Faith, Chap. 2, “On Revelation:” Denzinger 1786 ).
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 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 (Ibid: Denzinger 1785 and 1786 [3004 and 3005]).
