Genesis 11:5

“These and other such sayings are recorded by the lawgiver and by the prophets; and I suppose that I have stated sufficiently, that wherever God says, ‘God went up from Abraham,’ or, ‘The Lord spake to Moses,’ and ‘The Lord came down to behold the tower which the sons of men had built,’ or when ‘God shut Noah into the ark,’ you must not imagine that the unbegotten God Himself came down or went up from any place. For the ineffable Father and Lord of all neither has come to any place, nor walks, nor sleeps, nor rises up, but remains in His own place, wherever that is, quick to behold and quick to hear, having neither eyes nor ears, but being of indescribable might; and He sees all things, and knows all things, and none of us escapes His observation; and He is not moved or confined to a spot in the whole world, for He existed before the world was made. …

But though these nations are said to have been dispersed according to their languages, yet the narrator recurs to that time when all had but one language, and explains how it came to pass that a diversity of languages was introduced. “The whole earth,” he says, “was of one lip, and all had one speech. And it came to pass, as they journeyed from the east, that they found a plain in the land of Shinar, and dwelt there. And they said one to another, Come, and let us make bricks, and burn them thoroughly. And they had bricks for stone, and slime for mortar. And they said, Come, and let us build for ourselves a city, and a tower whose top shall reach the sky; and let us make us a name, before we be scattered abroad on the face of all the earth. And the Lord came down to see the city and the tower, which the children of men builded. …

10. But lo, say the disciples to the Lord, we are told in what name we are to baptize; Thou hast made us ministers, and hast said to us, “Go, baptize in the name of the Father, and of the Son, and of the Holy Ghost.” Whither shall we go? Whither? Have you not heard? To Mine inheritance. You ask, Whither shall we go? To that which I bought with my blood. Whither then? To the nations, saith He. I fancied that He said, Go, baptize the Africans in the name of the Father, and of the Son, and of the Holy Ghost. Thanks be to God, the Lord has solved the question the dove has taught us. Thanks be to God, it was to the nations the apostles were sent; if to the nations, then to all tongues. The Holy Spirit signified this, being divided in the tongues, united in the dove. Here the tongues are divided, there the dove unites them. …

213. But you ask, why did He not refuse His disciples as one who knew, but would not say; and, why did He state instead that neither the angels nor the Son knew? I too will ask you why God says in Genesis: “I will go down now, and see whether they have done altogether according to the cry that is come unto Me. And if not, that I may know.” Why does Scripture also say of God: “And the Lord came down to see the city and the tower, which the sons of men builded.” Why also does the prophet say in the Book of the Psalms: “The Lord looked down upon the children of men, to see if there were any that did understand, and that did seek God”? Just as though in one place, if God had not descended, and in the other, if He had not looked down, He would have been ignorant either of men’s work or of their merits.
