Gregory of Nyssa

The meaning of the “creation,” of which he is firstborn, is not unknown to us. For we recognize a twofold creation of our nature, the first that of our conception and birth, the second that of our new creation. But there would have been no need for the second creation had we not crippled the first by our disobedience. Accordingly, when the first creation had grown old and vanished away, it was necessary that there should be a new creation in Christ … for the maker of human nature at the first and afterwards is one and the same. Then he took dust from the earth and formed man: again he took dust from the Virgin and did not merely form man, but formed man about himself: then he created; afterwards, he was created: then the Word made flesh; afterwards, the Word became flesh, that he might change our flesh to spirit, through becoming a partaker with us in flesh and blood. Of this new creation therefore in Christ, which he himself began, he was called the firstborn.

And he is also a “beginning.” … But what benefits do we derive from believing that he is the beginning? We become ourselves what we believe our beginning to be. .

Since then it was impossible that our life, which had been estranged from God, should of itself return to the high and heavenly place, for this reason, as the apostle says, he who knew no sin is made sin for us and frees us from the curse by taking on him our curse as his own. Having taken up and, in the language of the apostle, “slain” in himself “the enmity” which by means of sin had come between us and God (in fact sin was the “enmity”) and having become what we were, he through himself again united humanity to God. For having by purity brought into closest relationship with the Father of our nature that new man which is created after God, in whom dwelled all the fullness of the Godhead bodily, he drew with him into the same grace all the nature that partakes of his body and is akin to him.

So … if reason instead assumes sway over such emotions, each of them is transmuted to a form of virtue. For anger produces courage, terror caution, fear obedience, hatred aversion from vice, the power of love the desire for what is truly beautiful. High spirit in our character raises our thought above the passions and keeps it from bondage to what is base. Indeed, even the great apostle praises such a form of mental elevation when he bids us constantly to “think those things that are above.” So we find that every such motion, when elevated by loftiness of mind, is conformed to the beauty of the divine image.

And even so we say that the true and perfect soul is the human soul, as is clear from the very nature of its operations in both sensory power and intellect. Anything else that shares in life, because it possesses the power of growth, we call animate by a sort of customary misuse of language, because in these cases the soul does not exist in a perfect condition…. Thus Paul, advising those who were able to hear him to lay hold on perfection, indicates also the mode in which they may attain that object. He tells them that they must “put off the old man” and put on the man “which is renewed after the image of him that created him.” Now may we all return to that divine grace in which God at the first created man, when he said, “Let us make man in our image and likeness.”
