"This proves that you [Manicheans] approve of having a wife, not for the procreation of children, but for the gratification of passion. In marriage, as the marriage law declares, the man and woman come together for the procreation of children. Therefore, whoever makes the procreation of children a greater sin than copulation, forbids marriage and makes the woman not a wife but a mistress, who for some gifts presented to her is joined to the man to gratify his passion."
