(ii) God was not changed by the incarnation; the Word was made flesh, not by a conversion of the Word into flesh, but by an assumption of the flesh to the hypostatis of the Word.
(iii) God changes the things he has created without changing himself. ‘The knowledge of God does not change with the thing known because God who knew it not only knew this change would take place but even decreed it.’(206)
There was no change in the Divine nature, when he assumed human nature. There was an union of the two natures, but no change of the Deity into the humanity, or of the humanity into the Deity; both preserved their peculiar properties. The humanity was changed by a communication of excellent gifts from the divine nature, not by being brought into an equality with it, for that was impossible that a creature should be equal to the Creator.
