On the Making of Man by Gregory of Nyssa — Read

Nor again are we in our doctrine to begin by making up man like a clay figure, and to say that the soul came into being for the sake of this; for surely in that case the intellectual nature would be shown to be less precious than the clay figure. But as man is one, the being consisting of soul and body, we are to suppose that the beginning of his existence is one, common to both parts, so that he should not be found to be antecedent and posterior to himself, if the bodily element were first in point of time, and the other were a later addition; but we are to say that in the power of God's foreknowledge (according to the doctrine laid down a little earlier in our discourse), all the fullness of human nature had preexistence (and to this the prophetic writing bears witness, which says that God "knoweth all things before they be"), and in the creation of individuals not to place the one element before the other, neither the soul before the body, nor the contrary, that man may not be at strife against himself, by being divided by the difference in point of time.

For as our nature is conceived as twofold, according to the apostolic teaching, made up of the visible man and the hidden man, if the one came first and the other supervened, the power of Him that made us will be shown to be in some way imperfect, as not being completely sufficient for the whole task at once, but dividing the work, and busying itself with each of the halves in turn.
