Pronouncements on Public Revelation
CONDEMNED Proposition 21:
FIRST VATICAN COUNCIL
The same Holy Mother Church holds and teaches that God, the beginning and end of all things, may be certainly known by the natural light of human reason by means of created things -- for the invisible things of Him from the creation of the world are clearly seen, being understood by the things that are made (Romans i: 20); but that it pleased His wisdom and bounty to reveal Himself and the eternal decrees of His will to mankind by another and supernatural way, as the Apostle says: "God, having spoken on diverse occasions and in many ways in times past to the fathers by the prophets, last of all, in these days has spoken to us by His Son (Hebrews i: 1ff) (canon i).
. . . Further, this supernatural revelation, according to the universal belief of the Church, declared by the Sacred Synod of Trent, is contained in the written books and unwritten traditions which, received by the Apostles from the mouth of Christ Himself, or from the Apostles themselves, by the dictation of the Holy Ghost, transmitted, as it were, from hand to hand, have come down even to us (Council of Trent, Session IV, "On the canon of Scripture").
Ludwig Ott, FUNDAMENTALS OF CATHOLIC DOGMA
With Christ and the Apostles General Revelation Concluded. Pope Pius X rejected the liberal Protestant and Modernistic doctrine of the evolution of religion through "New Revelations." Thus he condemned the proposition that: "The Revelation, which is the object of Catholic Faith, was not terminated with the Apostles." D 2021.
The clear teaching of Holy Writ and Tradition is that after Christ, and the Apostles who proclaimed the message of Christ, no further revelation will be made. Christ was the fulfillment of the Law of the Old Testament (Mt. 5, 17; 2, 21 et seq) and the absolute teacher of humanity (Mt. 23, 10: "One is your master, Christ"; cf. Mt. 28, 20). The Apostles saw in Christ: "the coming of the fullness of time" (Gal. 4,4) and regarded as their task, the preservation, integral and unfalsified, of the heritage of Faith entrusted to them by Christ (1 Tim. 6, 16; 6, 20; 2 Tim 1, 14; 2, 2; 3, 14). The Fathers indignantly repudiated the claim of the heretics to possess secret doctrines or new Revelations of the Holy Ghost. St. Irenaeus (Adv. haer III 1; IV 35, 8), and Tertullian (De praesc. 21) stress, against the Gnostics, that the full truth of revelation is contained in the doctrine of the Apostles which is preserved unfalsified through the uninterrupted succession of the bishops.
