So creation was simply God being God, although in a new and mysteriously free way, wherein He made an other to bring into His love. This has all been said before but it will take some explaining for us:
If, however, any one say, “What then? Could not God have exhibited man as perfect from beginning?” let him know that, inasmuch as God is indeed always the same and unbegotten as respects Himself, all things are possible to Him. But created things must be inferior to Him who created them, from the very fact of their later origin; for it was not possible for things recently created to have been uncreated. But inasmuch as they are not uncreated, for this very reason do they come short of the perfect. Because, as these things are of later date, so are they infantile; so are they unaccustomed to, and unexercised in, perfect discipline. For as it certainly is in the power of a mother to give strong food to her infant, [but she does not do so], as the child is not yet able to receive more substantial nourishment; so also it was possible for God Himself to have made man perfect from the first, but man could not receive this [perfection], being as yet an infant. And for this cause our Lord in these last times, when He had summed up all things into Himself, came to us, not as He might have come, but as we were capable of beholding Him. He might easily have come to us in His immortal glory, but in that case we could never have endured the greatness of the glory; and therefore it was that He, who was the perfect bread of the Father, offered Himself to us as milk, [because we were] as infants. He did this when He appeared as a man, that we, being nourished, as it were, from the breast of His flesh, and having, by such a course of milk nourishment, become accustomed to eat and drink the Word of God, may be able also to contain in ourselves the Bread of immortality, which is the Spirit of the Father.
So we could say that mankind was created with a natural attraction to and movement toward the Good. Humans are “wired for grace,” and thus a “true human” is one who images God as closely as possible. A complete human is one in union with the divine.
Sin, then, is a rejection of the good and a falling away from humanness. Sin is a rejection of love and hospitality, a despising of grace and a love of violence and cursing. As privation, of course, there is no such thing as “absolute evil.” This would be self-annihilation and non-existence, and God simply cannot tolerate this, since His good always outweighs our evil.
God doesn’t have to change to deal with evil either. Redemption is not a “new” habitus for God, even if it looks like it from our side of things, but rather it is simply God continuing to be the Highest Good, of which can allow no room for evil. The reason that God doesn’t zap it instantaneously is much the same as what Irenaeus says of creation.
And after such an introduction, we can move on to our point, which is to say that the only true humanity is Jesus Christ. He is the second Adam and fulfillment of the race. He is the seed that went into the ground to produce the fruit of glory. He is the man fully alive.
So the only true human is a Christian.
And thus the only true human society is a Christian society.
