V. Women must be excommunicated who refuse to return.
And if any women are so possessed by love of their later husbands as to prefer to remain with them than to return to their lawful partners, they are deservedly to be branded: so that they be even deprived of the Church's communion; for in a pardonable matter they have chosen to taint themselves with crime, showing that they have sought their own pleasure in their incontinence, when a rightful restitution could have obtained their forgiveness. Let them return then to their former state and make voluntary reparation, nor let that which a condition of necessity extorted from them be by any means turned into disgrace through evil desires; because, as those women who refuse to return to their husbands are to be held unholy, so they who return to an affection entered on with God's sanction are deservedly to be praised.
