Tertullian, Against Marcion 34
Christ forbids divorce, saying that anyone who dismisses his wife and marries another commits adultery, and that anyone who marries a woman dismissed by her husband is equally an adulterer—so that He also forbids divorce by making the marriage of a repudiated woman unlawful. Moses, however, permits repudiation in Deuteronomy: if a man takes a wife, lives with her, and then finds no favor in her because he discovers an indecent deed in her, he is to write a certificate of divorce, hand it to her, and send her out of his house (Deuteronomy).
Latin
(Sed Christus diuortium inhibet dicens: qui dimiserit uxorem suam et aliam duxerit, adulterium committet, (et) qui dimissam a uiro duxerit, aeque adulter est, - ut sic quoque prohibeat diuortium, inlicitum facit repudiatae matrimonium — Moyses uero permittit repudium in Deuteronomio: si sumserit quis uxorem et habitauerit cum ea, et euenerit non inuenire eam apud eum gratiam, eo quod inuentum sit in illa impudicum negotium, scribet libellum repudii et dabit in manu eius et dimittet illam de domo sua.
