“It is ours to believe, but His to know, and so let God the Word Himself, after receiving all that is proper to man, be man, and let man after His assumption and reception of all that is God, be no other than God. It must not be supposed because He is said to have been incarnate and mixed that therefore His substance was diminished. God knows that He mixes Himself without the natural corruption, and He is mixed in reality. He knows also that He so received in Himself as that no addition of increment accrues to Himself, as also He knows He infused His whole self so as to incur no diminution. Let us not then, in accordance with our weak intelligence, and forming conjectures on the teaching of experience and the senses, suppose that God and man are mixed after the manner of things created and equal mixed together, and that from such a confusion as this of the Word and of the flesh a body as it were was made. God forbid that this should be our belief, lest we should suppose that after the manner of things which are confounded together two natures were brought into one hypostasis. For a mention of this kind implies destruction of both parts; but Christ Himself, containing but not contained, who examines us but is Himself beyond examination, making full but not made full, everywhere at one and the same time being Himself whole and pervading the universe, through His pouring out His own power, as being moved with mercy, was mingled with the nature of man, though the nature of man was not mingled with the divine.”
