Matthew 19:7

What then ought they to have done after this? Ought they not to have held their peace, and to have commended the saying? ought they not to have marvelled at His wisdom? ought they not to have stood amazed at His accordance with the Father? But none of these things do they, but as though they were contending for the law, they say, "How then did Moses command to give a writing of divorcement, and to put her away?" And yet they ought not now to have brought this forward, but rather He to them; but nevertheless He doth not take advantage of them, nor doth He say to them, "I am not now bound by this," but He solves this too. And indeed if He had been an alien from the old covenant, He would not have striven for Moses, neither would He have argued positively from the things done once for all at the beginning; He would not have studied to show that His own precepts agreed with those of old. And indeed Moses had given many other commandments besides, both those about meats, and those about the Sabbath; wherefore then do they nowhere bring him forward, as here? From a wish to enlist the multitude of the husbands against him. For this was considered a thing indifferent with the Jews, and all used to do so much as this. Accordingly it was for this reason that when so many things had been said on the mount, they remembered this commandment only now.

Here they reveal the cavil which they had prepared; albeit the Lord had not given sentence of Himself, but had recalled to their minds ancient history, and the commands of God.

(ubi sup.) For how great was that hardness! When not even the intervention of a bill of divorce, which gave room for just and prudent men to endeavour to dissuade, could move them to renew the conjugal affection. And with what wit do the Manichæans blame Moses, as severing wedlock by a bill of divorce, and commend Christ as, on the contrary, confirming its force? Whereas according to their impious science they should have praised Moses for putting asunder what the devil had joined, and found fault with Christ who riveted the bonds of the devil.

This sentence of chastity seemed hard to these adulterers; but they could not make answer to the argument. Howbeit, they will not submit to the truth, but betake themselves for shelter to Moses, as men having a bad cause fly to some powerful personage, that where justice is not, his countenance may prevail; They say unto him, Why did Moses then command to give a writing of divorcement, and to put her away?
