As if He said: Why are ye offended that I called God My Father, and that I make Myself equal with God? I am equal, but equal in such a sense as is consistent with His having begotten Me; with My being from Him, not Him from Me. With the Son, being and power are one and the same thing. The Substance of the Son then being of the Father, the power of the Son is of the Father also: and as the Son is not of Himself, so He can not of Himself. The Son can do nothing of Himself, but what He seeth the Father do.— (xxi. 4). His seeing and His being born of the Father are the same. His vision is not distinct from His Substance, but the whole together is of the Father.
