That body of revelation, containing truths to be believed and principles of conduct, which was given by Christ to the Apostles, to be preserved by them and their successors, with the guarantee of infallibility for the guidance of the Church. It embraces the truths of both Scripture and Tradition. Some of its articles are explicit in Scripture, e.g., the Word was made flesh; and others are implicit, e.g., the Immaculate Conception. It closed with the death of the last surviving apostle. It is entrusted to the infallible magisterium of the Church to preserve, unfold, and defend the deposit. The word is found in 1 Timothy vi, 20, Depositum custodi, "Keep safe what has been entrusted to thee." . . . The term is consecrated by the First Council of the Vatican (session iii, cap. 4): "And the doctrine of faith which God revealed is proposed, not as a mere philosophical discovery to be elaborated by human minds, but as the divine deposit delivered by Christ to his spouse, to be by her faithfully guarded and infallibly declared."
