For many think such things to be pleasures only which are against nature, such as these sins of theirs. And those who are better than they, know them to be sins, but are overcome by pleasures, and darkness is the veil of their vicious practices. For he violates his marriage adulterously who uses it in a meretricious way, and hears not the voice of the Instructor, crying, “The man who ascends his bed, who says in his soul, Who seeth me? darkness is around me, and the walls are my covering, and no one sees my sins. Why do I fear lest the Highest will remember?”[576] Most wretched is such a man, dreading men’s eyes alone, and thinking that he will escape the observation of God. “For he knoweth not,” says the Scripture, “that brighter ten thousand times than the sun are the eyes of the Most High, which look on all the ways of men, and cast their glance into hidden parts.” Thus again the Instructor threatens them, speaking by Isaiah: “Woe be to those who take counsel in secret, and say, Who seeth us?”[577] For one may escape the light of sense, but that of the mind it is impossible to escape. For how, says Heraclitus, can one escape the notice of that which never sets? Let us by no means, then, veil our selves with the darkness; for the light dwells in us. “For the darkness,” it is said, “comprehendeth it not.”[578] And the very night itself is illuminated by temperate reason. The thoughts of good men Scripture has named “sleepless lamps;”[579] although for one to attempt even to practise concealment, with reference to what he does, is confessedly to sin. And every one who sins, directly wrongs not so much his neighbour if he commits adultery, as himself, because he has committed adultery, besides making himself worse and less thought of. For he who sins, in the degree in which he sins, becomes worse and is of less estimation than before; and he who has been overcome by base pleasures, has now licentiousness wholly attached to him. Wherefore he who commits fornication is wholly dead to God, and is abandoned by the Word as a dead body by the spirit. For what is holy, as is right, abhors to be polluted. But it is always lawful for the pure to touch the pure. Do not, I pray, put off modesty at the same time that you put off your clothes; because it is never right for the just man to divest himself of continence. For, lo, this mortal shall put on immortality; when the insatiableness of desire, which rushes into licentiousness, being trained to self-restraint, and made free from the love of corruption, shall consign the man to everlasting chastity. “For in this world they marry and are given in marriage.”[580] But having done with the works of the flesh, and having been clothed with immortality, the flesh itself being pure, we pursue after that which is according to the measure of the angels.
