Origen

“ If we take the word “man” to include every being who is according to the image of God, or every reasonable creature, then He will have no need that any should testify to Him of any reasonable being whatever, since He Himself, by the power given Him by the Father, knows them all. But if the term “man” be restricted to mortal animated reasonable beings, then it might be said, on the one hand, that He had need of testimony respecting the beings above man, and while His knowledge was adequate with regard to man it did not extend to those other beings. ”
