Reply to Faustus the Manichaean

²⁹ As regards not putting away a wife, there is no need to quote any other passage of the Old Testament than that referred to most appropriately in the Lord's reply to the Jews when they questioned Him on this subject. For when they asked whether it is lawful for a man to put away his wife for any reason, the Lord answered: "Have ye not read, that He that made them at the beginning made them male and female, and said, For this cause shall a man leave his father and mother, and shall cleave to his wife, and they two shall be one flesh?

Therefore they are no longer two, but one flesh. What therefore God has joined, let no man put asunder." Here the Jews, who thought that they acted according to the intention of the law of Moses in putting away their wives, are made to see from the book of Moses that a wife should not be put away. And, by the way, we learn here, from Christ's own declaration, that God made and joined male and female; so that by denying this, the Manichæans are guilty of opposing the gospel of Christ as well as the writings of Moses.

And supposing their doctrine to be true, that the devil made and joined male and female, we see the diabolical cunning of Faustus in finding fault with Moses for dissolving marriages by granting a bill of divorce, and praising Christ for strengthening the union by the precept in the Gospel. Instead of this, Faustus, consistently with his own foolish and impious notions, should have praised Moses for separating what was made and joined by the devil, and should have blamed Christ for ratifying a bond of the devil's workmanship.

To return, let us hear the good Master explain how Moses, who wrote of the conjugal chastity in the first union of male and female as so holy and inviolable, afterwards allowed the people to put away their wives. For when the Jews replied, "Why did Moses then command to give a writing of divorcement, and to put her away?" Christ said unto them, "Moses, because of the hardness of your heart, suffered you to put away your wives." This passage we have already explained. The hardness must have been great indeed which could not be induced to admit the restoration of wedded love, even though by means of the writing an opportunity was afforded for advice to be given to this effect by wise and upright men.

Then the Lord quoted the same law, to show both what was enjoined on the good and what was permitted to the hard; for, from what is written of the union of male and female, He proved that a wife must not be put away, and pointed out the divine authority for the union; and shows from the same Scriptures that a bill of divorcement was to be given because of the hardness of the heart, which might be subdued or might not.
