7 Let us speak then first to these who fear God, just in the manner of that woman who delights in wickedness; namely, she fears her husband lest he condemn her; to such let us first speak. O soul, which fearest God lest He condemn you, just as the woman fears, who delights in wickedness: fears her husband, lest she be condemned by her husband: as you are displeased at this woman, so be displeased at yourself. If perchance you have a wife, would you have your wife fear you thus, that she be not condemned by you?
That delighting in wickedness, she should be repressed only by the weight of the fear of you, not by the condemnation of her iniquity? You would have her chaste, that she may love you, not that she may fear you. Show yourself such to God, as you would have your wife be to you. And if you have not yet a wife, and wishest to have one, you would have her such. And yet what are we saying, brethren? That woman, whose fear of her husband is to be condemned by her husband, perhaps does not commit adultery, lest by some means or other it come to her husband's knowledge, and he deprive her of this temporal light of life: now the husband can be deceived and kept in ignorance; for he is but human, as she is who can deceive him.
She fears him, from whose eyes she can be hid: and do you not fear the face ever upon you of your Husband? “The countenance of the Lord is against them that do evil.” She catches at her husband's absence, and haply is incited by the delight of adultery; and yet she says to herself, I will not do it: he indeed is absent, but it is hard to keep it from coming in some way to his knowledge. She restrains herself, lest it come to the knowledge of a mortal man, one who, it is also possible, may never know it, who, it is also possible, may be deceived, so that he shall esteem a bad woman to be good, esteem her to be chaste who is an adulteress: and do you not fear the eyes of Him whom no man can deceive? thou not fear the presence of Him who cannot be turned away from you?
Pray God to look upon you, and to turn His face away from your sins; “Turn away Your face from my sins.” But whereby do you merit that He should turn away His face from your sins, if you turn not away your own face from your sins? For the same voice says in the Psalm: “For I acknowledge my iniquity, and my sin is ever before me.” Acknowledge, and He forgives.
