Matthew 19:9

9.But I say to you. Mark relates that this was spoken to the disciples apart, when they had come into the house; but Matthew, leaving out this circumstance, gives it as a part of the discourse, as the Evangelists frequently leave out some intermediate occurrence, because they reckon it enough to sum up the leading points. There is therefore no difference, except that the one explains the matter more distinctly than the other. The substance of it is: though the Law does not punish divorces, which are at variance with God’s first institution, yet he is an adulterer who rejects his wife and takes another. For it is not in the power of a man to dissolve the engagement of marriage, which the Lord wishes to remain inviolate; and so the woman who occupies the bed of a lawful wife is a concubine.

But an exception is added; for the woman, by fornication, cuts herself off, as a rotten member, from her husband, and sets him at liberty. Those who search for other reasons ought justly to be set at nought, because they choose to be wise above the heavenly teacher. They say that leprosy is a proper ground for divorce, because the contagion of the disease affects not only the husband, but likewise the children. For my own part, while I advise a religious man not to touch a woman afflicted with leprosy, I do not pronounce him to be at liberty to divorce her. If it be objected, that they who cannot live unmarried need a remedy, that they may not be burned, I answer, that what is sought in opposition to the word of God is not a remedy. I add too, that if they give themselves up to be guided by the Lord, they will never want continence, for they follow what he has prescribed. One man shall contract such a dislike of his wife, that he cannot endure to keep company with her: will polygamy cure this evil? Another man’s wife shall fall into palsy or apoplexy, or be afflicted with some other incurable disease, shall the husband reject her under the pretense of incontinency? We know, on the contrary, that none of those who walk in their ways are ever left destitute of the assistance of the Spirit.

For the sake of avoiding fornication, says Paul, let every man marry a wife, (1 Corinthians 7:2.) He who has done so, though he may not succeed to his wish, has done his duty; and, therefore, if any thing be wanting, he will be supported by divine aid. To go beyond this is nothing else than to tempt God. When Paul mentions another reason, namely, that when, through a dislike of godliness, wives happen to be rejected by unbelievers, a godly brother or sister is not, in such a case, liable to bondage, (1 Corinthians 7:12,) this is not inconsistent with Christ’s meaning. For he does not there inquire into the proper grounds of divorce, but only whether a woman continues to be bound to an unbelieving husband, after that, through hatred of God, she has been wickedly rejected, and cannot be reconciled to him in any other way than by forsaking God; and therefore we need not wonder if Paul think it better that she should part with a mortal man than that she should be at variance with God.

But the exception which Christ states appears to be superfluous. For, if the adulteress deserve to be punished with death, what purpose does it serve to talk of divorces? But as it was the duty of the husband to prosecute his wife for adultery, in order to purge his house from infamy, whatever might be the result, the husband, who convicts his wife of uncleanness, is here freed by Christ from the bond. It is even possible that, among a corrupt and degenerate people, this crime remained to a great extent unpunished; as, in our own day, the wicked forbearance of magistrates makes it necessary for husbands to put away unchaste wives, because adulterers are not punished. It must also be observed, that the right belongs equally and mutually to both sides, as there is a mutual and equal obligation to fidelity. For, though in other matters the husband holds the superiority, as to the marriage bed, the wife has an equal right: for he is not the lord of his body; and therefore when, by committing adultery, he has dissolved the marriage, the wife is set at liberty.

And whosoever shall marry her that is divorced. This clause has been very ill explained by many commentators; for they have thought that generally, and without exception, celibacy is enjoined in all cases when a divorce has taken place; and, therefore, if a husband should put away an adulteress, both would be laid under the necessity of remaining unmarried. As if this liberty of divorce meant only not to lie with his wife; and as if Christ did not evidently grant permission in this case to do what the Jews were wont indiscriminately to do at their pleasure. It was therefore a gross error; for, though Christ condemns as an adulterer the man who shall marry a wife that has been divorced, this is undoubtedly restricted to unlawful and frivolous divorces. In like manner, Paul enjoins those who have been so dismissed

to remain unmarried, or to be reconciled to their husbands,
(1 Corinthians 7:11;)

that is, because quarrels and differences do not dissolve a marriage. This is clearly made out from the passage in Mark, where express mention is made of the wife who has left her husband: and if the wife shall divorce her husband Not that wives were permitted to give their husbands a letter of divorcement, unless so far as the Jews had been contaminated by foreign customs; but Mark intended to show that our Lord condemned the corruption which was at that time universal, that, after voluntary divorces, they entered on both sides into new marriages; and therefore he makes no mention of adultery.
