18 Wherefore I admonish both men and women who follow after perpetual continence and holy virginity, that they so set their own good before marriage, as that they judge not marriage an evil: and that they understand that it was in no way of deceit, but of plain truth that it was said by the Apostle, “Whoso gives in marriage does well; and whoso gives not in marriage, does better; and, if you shall have taken a wife, you have not sinned; and, if a virgin shall have been married, she sins not;” and a little after, “But she will be more blessed, if she shall have continued so, according to my judgment.”
And, that the judgment should not be thought human, he adds, “But I think I also have the Spirit of God.” This is the doctrine of the Lord, this of the Apostles, this true, this sound, so to choose greater gifts, as that the lesser be not condemned. The truth of God, in the Scripture of God, is better than virginity of man in the mind or flesh of any. Let what is chaste be so loved, as that what is true be not denied. For what evil thought may they not have even concerning their own flesh, who believe that the tongue of the Apostle, in that very place, wherein he was commending virginity of body, was not virgin from corruption of lying.
In the first place, therefore, and chiefly, let such as choose the good of virginity, hold most firmly that the holy Scriptures have in nothing spoken lies; and, thus, that that also is true which is said, “And if you shall have taken a wife, you have not sinned; and, if a virgin shall have been married, she sins not.” And let them not think that the so great good of virgin chastity is made less, if marriage shall not be an evil. Yea rather, let her hence feel confident, rather, that there is prepared for her a palm of greater glory, who feared not to be condemned, in case she were married, but desired to receive a more honorable crown, in that she was not married.
Whoso therefore shall be willing to abide without marriage, let them not flee from marriage as a pitfall of sin; but let them surmount it as a hill of the lesser good, in order that they may rest in the mountain of the greater, continence. It is on this condition, forsooth, that this hill is dwelt on; that one leave it not when he will. For, “a woman is bound, so long as her husband lives.” However unto widowed continence one ascends from it as from a step: but for the sake of virgin continence, one must either turn aside from it by not consenting to suitors, or overleap it by anticipating suitors.
