Holy Scripture is of all things most sufficient for us. - Athanasius of Alexandria

Death has become like a tyrant who has been completely conquered by the legitimate monarch; bound hand and foot the passers-by sneer at him, hitting him and abusing him, no longer afraid of his cruelty and rage, because of the king who has conquered him. So has death been conquered

For of what use is existence to the creature if it cannot know its Maker? How could men be reasonable beings if they had no knowledge of the Word and Reason of the Father, through Whom they had received their being? They would be no better than the beasts, had they no knowledge save of earthly things; and why should God have made them at all, if He had not intended them to know Him? But, in fact, the good God has given them a share in His own Image, that is, in our Lord Jesus Christ, and has made even themselves after the same Image and Likeness. Why? Simply in order that through this gift of Godlikeness in themselves they may be able to perceive the Image Absolute, that is the Word Himself, and through Him to apprehend the Father; which knowledge of their Maker is for men the only really happy and blessed life.

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.
