For if the mystery concealed of old is made manifest to the Apostles through the prophetic writings, and if the prophets, being wise men, understood what proceeded from their own mouths, then the prophets knew what was made manifest to the Apostles.
OrigenThe Church received from the apostles the tradition of giving baptism even to infants. The apostles, to whom were committed the secrets of the divine sacraments, knew there are in everyone innate strains of [original] sin, which must be washed away through water and the Spirit
OrigenWe must believe what is good and true about the prophets, that they were sages, that they did understand what proceeded from their mouths, and that they bore prudence on their lips.
OrigenThe honor that we pay to the Son of God, as well as that which we render to God the Father, consists of an upright course of life. This is plainly taught us by the passage, "You that boast of the Law, through breaking the Law dishonor God."...For if he who transgresses the law dishonors God by his transgression,...it is evident that he who keeps the law honors God. So the worshipper of God is he whose life is regulated by the principles and teachings of the Divine Word
