123. There is, then, a Unity of knowledge, since, as the Father, Who gives the Spirit of revelation, reveals, so also the Son reveals, for it is written: “No one knoweth the Son save the Father, neither doth any one know the Father save the Son, and he to whom the Son shall will to reveal Him.” S. Matt. xi. 27. He said more concerning the Son, not because He has more than the Father, but lest He should be supposed to have less. And not unfittingly is the Father thus revealed by the Son, for the Son knows the Father even as the Father knows the Son.
