4. Now, that the preaching of the apostles, the authoritative teaching of the Lord, the announcements of the prophets, the dictated utterances of the apostles, and the ministration of the law—all of which praise one and the same Being, the God and Father of all, and not many diverse beings, nor one deriving his substance from different gods or powers, but [declare] that all things [were formed] by one and the same Father (who nevertheless adapts [His works] to the natures and tendencies of the materials dealt with), things visible and invisible, and, in short, all things that have been made [were created] neither by angels, nor by any other power, but by God alone, the Father—are all in harmony with our statements, has, I think, been sufficiently proved, while by these weighty arguments it has been shown that there is but one God, the Maker of all things. But that I may not be thought to avoid that series of proofs which may be derived from the Scriptures of the Lord (since, indeed, these Scriptures do much more evidently and clearly proclaim this very point), I shall, for the benefit of those at least who do not bring a depraved mind to bear upon them, devote a special book to the Scriptures referred to, which shall fairly follow them out [and explain them], and I shall plainly set forth from these divine Scriptures proofs to [satisfy] all the lovers of truth.
