8 You call yourself wealthy and rich; but Paul meets your riches, and with his own voice prescribes for the moderating of your dress and ornament within a just limit. “Let women,” said he, “adorn themselves with shamefacedness and sobriety, not with broidered hair, nor gold, nor pearls, nor costly array, but as becomes women professing chastity, with a good conversation.” Also Peter consents to these same precepts, and says, “Let there be in the woman not the outward adorning of array, or gold, or apparel, but the adorning of the heart.” But if these also warn us that the women who are accustomed to make an excuse for their dress by reference to their husband, should be restrained and limited by religious observance to the Church's discipline, how much more is it right that the virgin should keep that observance, who has no excuse for adorning herself, nor can the deceitfulness of her fault be laid upon another, but she herself remains in its guilt!
