43. Now we ought to recognise first of all that
God has spoken not for Himself but for us, and that He has so far
tempered the language of His utterance as to enable the weakness of our
nature to grasp and understand it. For after being rebuked by the
Jews for having made Himself the equal of God by professing to be the
Son of God, He had answered that He Himself did all things that the
Father did, and that He had received all judgment from the Father;
moreover that He must be honoured even as the Father. And in all
these things having before declared Himself Son, He had made Himself
equal to the Father in honour, power and nature. Afterwards He
had said that as the Father had life in Himself, so He had given the
Son to have life in Himself, wherein He signified that by virtue of the
mystery of the birth He possessed the unity of the same nature.
For when He says that He has what the Father has, He means that He has
the Father’s self. For that God is not after human fashion
of a composite being, so that in Him there is a difference of kind
between Possessor and Possessed; but all that He is is life, a nature,
that is, complete, absolute and infinite, not composed of dissimilar
elements but with one life permeating the whole. And since this
life was in such wise given as it was possessed, although the fact that
it was given manifestly reveals the birth of the Recipient, it yet does
not involve a difference of kind since the life given was such as was
possessed.
