He saw how the surpassing wickedness of men was mounting up against them; He saw also their universal liability to death. All this He saw and, pityin… - Athanasius of Alexandria

But when the human being had once been made, and necessity required the healing, not for the things that were not, but for the things that had come to be, it followed that the healer and Savior had to come among those who had already been created, to heal what existed. He became a human being for this, and used his body as a human instrument. For if it was not right to happen in this way, how should the Word appear, when he wished to use an instrument? Or whence was he to take it, if not from those who already existed and had need of his divinity through one like [themselves]? For it was not non-existent things that needed salvation, so that a command alone would have sufficed, but the human being, already in existence, who was corrupted and perishing. Whence it was reasonable and good that the Word should use a human instrument and unfold himself to all things.

For in other matters also which go to make up life, we shall find differences according to circumstances. For example, it is not right to kill, yet in war it is lawful and praiseworthy to destroy the enemy; accordingly not only are they who have distinguished themselves in the field held worthy of great honours, but monuments are put up proclaiming their achievements. So that the same act is at one time and under some circumstances unlawful, while under others, and at the right time, it is lawful and permissible. The same reasoning applies to the relation of the sexes. He is blessed who, being freely yoked in his youth, naturally begets children. But if he uses nature licentiously, the punishment of which the Apostle writes shall await whoremongers and adulterers.
For there are two ways in life, as touching these matters. The one the more moderate and ordinary, I mean marriage; the other angelic and unsurpassed, namely virginity. Now if a man choose the way of the world, namely marriage, he is not indeed to blame; yet he will not receive such great gifts as the other. For he will receive, since he too brings forth fruit, namely thirtyfold. But if a man embrace the holy and unearthly way, even though, as compared with the former, it be rugged and hard to accomplish, yet it has the more wonderful gifts: for it grows the perfect fruit, namely an hundredfold. So then their unclean and evil objections had their proper solution long since given in the divine Scriptures.

You cannot put straight in others what is warped in yourself.
