Deuteronomy 24:3

After this we will discuss the saying of the Pharisees which they said to Jesus, “ Why then did Moses command to give a bill of divorcement and put her away? ” And with good reason we will bring forward for this purpose the passage from Deuteronomy concerning the bill of divorcement, which is as follows: “But if a man taketh a wife and cohabit with her, and it shall be, if she do not find favour in his sight because he hath found in her a thing unseemly,” etc., down to the words, “and ye shall not pollute the land which the Lord your God giveth you for an inheritance.” Now I inquire whether in these things according to this law, we are to seek nothing in it beyond the letter seeing that God has not given it, or whether to the Pharisees who quoted the saying, “Moses commanded to give a bill of divorcement and put her away,” it was of necessity said, “Moses, for your hardness of heart, suf …

Now, keeping in mind what we said above in regard to the passage from Isaiah about the bill of divorcement, we will say that the mother of the people separated herself from Christ, her husband, without having received the bill of divorcement, but afterwards when there was found in her an unseemly thing, and she did not find favour in his sight, the bill of divorcement was written out for her; for when the new covenant called those of the Gentiles to the house of Him who had cast away his former wife, it virtually gave the bill of divorcement to her who formerly separated from her husband, the law, and the Word. Therefore he, also, having separated from her, married, so to speak, another, having given into the hands of the former the bill of divorcement; wherefore they can no longer do the things enjoined on them by the law, because of the bill of divorcement. …

Now there are those in whose case it has happened that the man dwells with them without having hated them, because they abide in the house of the last husband, who took to himself their synagogue as wife. But also in their case the latter husband dies, perhaps whenever the last enemy of Christ, death, is destroyed. But whichever of these things may happen, whether the former or the latter to the wife, the former husband, it says, who sent her away, will not he able to turn back and take her to be a wife to himself after she has been defiled, since “it is abomination,” it says, “before the Lord thy God.” But these things will not seem to be consistent with this, “If the fulness of the Gentiles be come in, all Israel shall be saved.” But consider if it can be said to this, that, if she shall be saved by her former husband returning and taking her to himself as wife, she will in any case be …

He goes not on to what lies before Him, until He have well cleared out the former topics. For, lo, He shows us yet another kind of adultery. And what is this? There was an ancient law made,that he who hated his wife, for whatever kind of cause, should not be forbidden to cast her out, and to bring home another instead of her. The law however did not command him simply to do this, but after giving the woman a writing of divorcement, that it might not be in her power to return to him again; that so at least the figure of the marriage might remain.

4. I have not been able quite to determine what it is that she means by the words “has found herself compelled” to marry again. What is this compulsion of which she speaks? Was she overborne by a crowd and ravished against her will? If so, why has she not, thus victimized, subsequently put away her ravisher? Let her read the books of Moses and she will find that if violence is offered to a betrothed virgin in a city and she does not cry out, she is punished as an adulteress: but if she is forced in the field, she is innocent of sin and her ravisher alone is amenable to the laws. …
