Matthew 5:32

Shepherd of Hermas Commandment Fourth " And I said to him, "What then, sir, is the husband to do, if his wife continue in her vicious practices? "And he said, "The husband should put her away, and remain by himself. But if he put his wife away and marry another, he also commits adultery."[3]

Tertullian On Monogamy " But another reason, too, conspires; nay, not another, but (one)which imposed the law of "the beginning," and moved the will of God to prohibit divorce: the fact that (he)who shall have dismissed his wife, except on the ground of adultery, makes her commit adultery; and (he) who shall have married a (woman) dismissed by her husband, of course commits adultery.[78]

Tertullian On Modesty

Meantime withal, while prohibiting divorce, he uses the Lord's precept against adultery as an instrument for providing, in place of divorce, either perseverance in widowhood, or else a reconciliation of peace: inasmuch as "whoever shall have dismissed a wife (for any cause) except the cause of adultery, maketh her commit adultery; and he who marrieth one dismissed by a husband committeth adultery."[179]
