“If the mixture with soul and body, although from the beginning they coalesce, does not make the soul visible on account of the body, nor change it into the other properties of the body, so as to allow of its being cut or lessened, how much rather God, who is not of the same nature as the body, is united to the body without undergoing change, if the body of man remains in its own nature, and this when it is animated by a soul, then in the case of Christ the commingling does not so change the body as that it is not a body.”
