Cyril of Alexandria

Admittedly the divine, because it is without a body, is untouchable and entirely intact, because the divine is beyond every creature, both visible and intelligible, and in nature it is incorporeal, immaculate, untouchable and incomprehensible. Since the only-begotten Word of God, having taken a body from the holy virgin, and, as I already said over and over again, having made it his own, offered himself in an odor of sweetness to God the Father as a spotless sacrifice, in this way it is asserted that he endured on our behalf what happened to his flesh. Everything that happened to flesh would rightly be attributed to him, sin alone excepted, for it is his own body. Accordingly, since God the Word became man, he remained impassible as God, but, because he necessarily made the things of his flesh his own, it is asserted that he endured what is according to flesh, although he is without experience of suffering in so far as he is thought of as God.

When God offers us conversion on whatever day one may be willing to practice it, why do they not instead crown with grateful praises him who aids them, instead of foolishly and (we might say) contumaciously opposing him? For by so doing they bring condemnation on their own heads and call down on themselves inevitable wrath.

To be made partakers of Christ, both intellectually and by our senses, fills us with every blessing. For he dwells in us, first, by the Holy Spirit, and we are his abode, according to that which was said of old by one of the holy prophets.

The word was made flesh without sexual intercourse, being conceived altogether without seed; then he was born without injury to her virginity.
