Library Pseudo-Clement Clementine Homilies
Homily 2, Chapter 49: Reductio a.d. Absurdum

He who wrote the Bible, and told how the world was made, and said that God does not foreknow, was he a man or not?
Then I said: He was a man.
Then Peter answered: How, then, was it possible for him, being a man, to know assuredly how the world was made, and that God does not foreknow?
