9. Consider, however, how ancient is the mystery prefigured even in the origin of the world itself. In the very beginning, when God made the heaven and the earth, “the Spirit,” it is said, “moved upon the waters.” He Who was moving upon the waters, was He not working upon the waters? But why should I say, “working”? As regards His presence He was moving. Was He not working Who was moving? Recognize that He was working in that making of the world, when the prophet says: “By the word of the Lord were the heavens made, and all their strength by the spirit of His mouth.” Each statement rests upon the testimony of the prophet, both that He was moving and that He was working. Moses says that He was moving, David testifies that he was working.
