Inasmuch as the words of the Lord are numerous, while they all proclaim one and the same Father, the Creator of this world, it was incumbent also upon me, for their own sake, to refute by many [arguments] those who are involved in many errors, if by any means, when they are confuted by many [proofs], they may be converted to the truth and saved. But it is necessary to subjoin to this composition, in what follows, also the doctrine of Paul after the words of the Lord, to examine the opinion of this man, and expound the apostle, and to explain whatsoever [passages] have received other interpretations from the heretics, who have altogether misunderstood what Paul has spoken, and to point out the folly of their mad opinions; and to demonstrate from that same Paul, from whose [writings] they press questions upon us, that they are indeed utterers of falsehood, but that the apostle was a preacher of the truth, and that he taught all things agreeable to the preaching of the truth; [to the effect that] it was one God the Father who spake with Abraham, who gave the law, who sent the prophets beforehand, who in the last times sent His Son, and conferred salvation upon His own handiwork --that is, the substance of flesh. Arranging, then, in another book, the rest of the words of the Lord, which He taught concerning the Father not by parables, but by expressions taken in their obvious meaning (sed simpliciter ipsis dictionibus), and the exposition of the Epistles of the blessed apostle, I shall, with God's aid, furnish thee with the complete work of the exposure and refutation of knowledge, falsely so called; thus practising myself and thee in [these] five books for presenting opposition to all heretics.
