13 Those therefore, who do not marry because of exaggerated self-interest, or because, as Augustine says, they shun the burdens of marriage or because like Pharisees they proudly flaunt their physical integrity, an attitude which has been condemned by the Council of Gangra lest men and women renounce marriage as though it were something despicable instead of because virginity is something beautiful and holy, - none of these can claim for themselves the honor of Christian virginity.
