“If, however, we cannot discover explanations of all those things in Scripture which are made the subject of investigation, yet let us not on that account seek after any other God besides Him who really exists. For this is the very greatest impiety. We should leave things of that nature to God who created us, being most properly assured that the Scriptures are indeed perfect, since they were spoken by the Word of God and His Spirit; but we, inasmuch as we are inferior to, and later in existence than, the Word of God and His Spirit, are on that very account destitute of the knowledge of His mysteries. And there is no cause for wonder if this is the case with us as respects things spiritual and heavenly, and such as require to be made known to us by revelation, since many even of those things which lie at our very feet (I mean such as belong to this world, which we handle, and see, and are in close contact with) transcend our knowledge, so that even these we must leave to God. For it is fitting that He should excel all [in knowledge]” (Against Heresies, Book II: Chapter 28, paragraph 2).
