Theophilus to Autolycus

You will say, then, to me: “You said that God ought not to be contained in a place, and how do you now say that He walked in Paradise?” Hear what I say. The God and Father, indeed, of all cannot be contained, and is not found in a place, for there is no place of His rest; but His Word, through whom He made all things, being His power and His wisdom, assuming the person of the Father and Lord of all, went to the garden in the person of God, and conversed with Adam. For the divine writing itself teaches us that Adam said that he had heard the voice.

But what else is this voice but the Word of God, who is also His Son? Not as the poets and writers of myths talk of the sons of gods begotten from intercourse [with women], but as truth expounds, the Word, that always exists, residing within the heart of God. For before anything came into being He had Him as a counsellor, being His own mind and thought. But when God wished to make all that He determined on, He begot this Word, uttered, the first-born of all creation, not Himself being emptied of the Word [Reason], but having begotten Reason, and always conversing with His Reason.

And hence the holy writings teach us, and all the spirit-bearing [inspired] men, one of whom, John, says, “In the beginning was the Word, and the Word was with God,” showing that at first God was alone, and the Word in Him. Then he says, “The Word was God; all things came into existence through Him; and apart from Him not one thing came into existence.” The Word, then, being God, and being naturally produced from God, whenever the Father of the universe wills, He sends Him to any place; and He, coming, is both heard and seen, being sent by Him, and is found in a place.
