Luke 16:18

"Sir, if any one has a wife who trusts in the Lord, and if he detect her in adultery, does the man sin if he continue to live with her?" And he said to me, "As long as he remains ignorant of her sin, the husband commits no transgression in living with her. But if the husband know that his wife has gone astray, and if the woman does not repent, but persists in her fornication, and yet the husband continues to live with her, he also is guilty of her crime, and a sharer in her adultery." 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." And I said to him, "What if the woman put away should repent, and wish to return to her husband: shall she not be taken back by her husband?" And he said to me, "Assuredly. If the husband do not take her back, he sins, and brings a great sin upon himself; for he ought to take back the sinner who has repented. But not frequently. For there is but one repentance to the servants of God. In case, therefore, that the divorced wife may repent, the husband ought not to marry another, when his wife has been put away. In this matter man and woman are to be treated exactly in the same way."

"Whosoever shall marry her that is divorced from another husband, committeth adultery." And, "There are some who have been made eunuchs of men, and some who were born eunuchs, and some who have made themselves eunuchs for the kingdom of heaven's sake; but all cannot receive this saying." So that all who, by human law, are twice married, are in the eye of our Master sinners, and those who look upon a woman to lust after her.

And concerning chastity, the holy word teaches us not only not to sin in act, but not even in thought, not even in the heart to think of any evil, nor look on another man's wife with our eyes to lust after her. Solomon, accordingly, who was a king and a prophet, said: "Let thine eyes look right on, and let thine eyelids look straight before thee: make straight paths for your feet." And the voice of the Gospel teaches still more urgently concerning chastity, saying: "Whosoever looketh on a woman who is not his own wife, to lust after her, hath committed adultery with her already in his heart." [Matthew 5:28] "And he that marrieth," says [the Gospel], "her that is divorced from her husband, committeth adultery; and whosoever putteth away his wife, saving for the cause of fornication, causeth her to commit adultery." [Matthew 5:32] Because Solomon says: "Can a man take fire in his bosom, and his clothes not be burned? Or can one walk upon hot coals, and his feet not be burned? So he that goeth in to a married woman shall not be innocent." [Proverbs 6:27-29]

A person should either remain as he was born, or be content with one marriage; for a second marriage is only a specious adultery. "For whosoever puts away his wife," says He, "and marries another, commits adultery;" [Matthew 19:9] not permitting a man to send her away whose virginity he has brought to an end, nor to marry again. For he who deprives himself of his first wife, even though she be dead, is a cloaked adulterer, resisting the hand of God, because in the beginning God made one man and one woman, and dissolving the strictest union of flesh with flesh, formed for the intercourse of the race.

Now that the Scripture counsels marriage, and allows no release from the union, is expressly contained in the law, "Thou shalt not put away thy wife, except for the cause of fornication;" and it regards as fornication, the marriage of those separated while the other is alive. Not to deck and adorn herself beyond what is becoming, renders a wife free of calumnious suspicion, while she devotes herself assiduously to prayers and supplications; avoiding frequent departures from the house, and shutting herself up as far as possible from the view of all not related to her, and deeming housekeeping of more consequence than impertinent trifling. "He that taketh a woman that has been put away," it is said, "committeth adultery; and if one puts away his wife, he makes her an adulteress," that is, compels her to commit adultery. And not only is he who puts her away guilty of this, but he who takes her, by giving to the woman the opportunity of sinning; for did he not take her, she would return to her husband.

But Christ prohibits divorce, saying, "Whosoever putteth away his wife, and marrieth another, committeth adultery; and whosoever marrieth her that is put away from her husband, also committeth adultery." In order to forbid divorce, He makes it unlawful to marry a woman that has been put away.

His words are: "Whosoever putteth away his wife, and marrieth another, committeth adultery; and whosoever marrieth her that is put away from her husband, also committeth adultery," -"put away," that is, for the reason wherefore a woman ought not to be dismissed, that another wife may be obtained.

But perhaps some Jewish man of those who dare to oppose the teaching of our Saviour will say, that when Jesus said, "Whosoever shall put away his own wife, saving for the cause of fornication, makes her an adulteress," [Matthew 5:32] He also gave permission to put away a wife like as well as Moses did, who was said by Him to have given laws for the hardness of heart of the people, and will hold that the saying, "Because he found in her an unseemly thing," [Deuteronomy 24:1] is to be reckoned as the same as fornication on account of which with good cause a wife could be cast away from her husband. But to him it must be said that, if she who committed adultery was according to the law to be stoned, clearly it is not in this sense that the unseemly thing is to be understood. For it is not necessary for adultery or any such great indecency to write a bill of divorcement and give it into the hands of the wife; but indeed perhaps Moses called every sin an unseemly thing, on the discovery of which by the husband in the wife, as not finding favour in the eyes of her husband, the bill of divorcement is written, and the wife is sent away from the house of her husband; "but from the beginning it has not been so." [Matthew 19:8] After this our Saviour says, not at all permitting the dissolution of marriages for any other sin than fornication alone, when detected in the wife, "Whosoever shall put away his own wife, saving for the cause of fornication, makes her an adulteress." [Matthew 5:32] But it might be a subject for inquiry if on this account He hinders any one putting away a wife, unless she be caught in fornication, for any other reason, as for example for poisoning, or for the destruction during the absence of her husband from home of an infant born to them, or for any form of murder whatsoever. And further, if she were found despoiling and pillaging the house of her husband, though she was not guilty of fornication, one might ask if he would with reason cast away such an one, seeing that the Saviour forbids any one to put away his own wife saving for the cause of fornication. In either case there appears to be something monstrous, whether it be really monstrous, I do not know; for to endure sins of such heinousness which seem to be worse than adultery or fornication, will appear to be irrational; but again on the other hand to act contrary to the design of the teaching of the Saviour, every one would acknowledge to be impious. I wonder therefore why He did not say, Let no one put away his own wife saving for the cause of fornication, but says, "Whosoever shall put away his own wife, saving for the cause of fornication, makes her an adulteress." [Matthew 5:32] For confessedly he who puts away his wife when she is not a fornicator, makes her an adulteress, so far as it lies with him, for if, "when the husband is living she shall be called an adulteress if she be joined to another man;" [Romans 7:3] and when by putting her away, he gives to her the excuse of a second marriage, very plainly in this way he makes her an adulteress. But as to whether her being caught in the act of poisoning or committing murder, furnishes any defense of his dismissal of her, you can inquire yourselves; for the husband can also in other ways than by putting her away cause his own wife to commit adultery; as, for example, allowing her to do what she wishes beyond what is fitting, and stooping to friendship with what men she wishes, for often from the simplicity of husbands such false steps happen to wives; but whether there is a ground of defense or not for such husbands in the case of such false steps, you will inquire carefully, and deliver your opinion also in regard to the difficult questions raised by us on the passage. And even he who withholds himself from his wife makes her oftentimes to be an adulteress when he does not satisfy her desires, even though he does so under the appearance of greater gravity and self-control. And perhaps this man is more culpable who, so far as it rests with him, makes her an adulteress when he does not satisfy her desires than he who, for other reason than fornication, has sent her away — for poisoning or murder or any of the most grievous sins. But as a woman is an adulteress, even though she seem to be married to a man, while the former husband is still living, so also the man who seems to marry her who has been put away, does not so much marry her as commit adultery with her according to the declaration of our Saviour.

If a layman divorces his own wife, and takes another, or one divorced by another, let him be suspended.

But we must first speak, I think, of the law of marriage, that we may afterwards discuss the forbidding of divorce. Some think that all marriage is sanctioned by God, because it is written, Whom God hath joined, let not man put asunder. (Matt. 19:6.) How then does the Apostle say, If the unbelieving depart, let him depart? (Mark 10:9, 1 Cor. 7:15.) Herein he shows that the marriage of all is not from God. For neither by God's approval are Christians joined with Gentiles. Do not then put away thy wife, lest thou deny God to be the Author of thy union. For if others, much more oughtest thou to bear with and correct the behaviour of thy wife. And if she is sent away pregnant with children, it is a hard thing to shut out the parent and keep the pledge; so as to add to the parents' disgrace the loss also of filial affection. Harder still if because of the mother thou drivest away the children also. Wouldest thou suffer in thy lifetime thy children to be under a step-father, or when the mother was alive to be under a step-mother? How dangerous to expose to error the tender age of a young wife. How wicked to desert in old age one, the flower of whose growth thou hast blighted. Suppose that being divorced she does not marry, this also ought to be displeasing to you, to whom though an adulterer, she keeps her troth. Suppose she marries, her necessity is thy crime, and that which thou supposest marriage, is adultery.
But to understand it morally. Having just before set forth that the kingdom of God is preached, and said that one tittle could not fall from the Law, He added, Whosoever putteth away his wife, &c. Christ is the husband; whomsoever then God has brought to His son, let not persecution sever, nor lust entice, nor philosophy spoil, nor heretics taint, nor Jew seduce. Adulterers are all such as desire to corrupt truth, faith, and wisdom.

He had above proposed that the kingdom of God should be preached. When he had said that one tittle cannot fall from the law, he added, "Everyone who puts away his wife, and marries another, commits adultery." The apostle rightly admonishes, saying that this is a great sacrament concerning Christ and the church. You find a marriage that doubtlessly was joined by God, when he himself says, "No man comes to me, unless my Father who sent me has drawn him." He alone could join this marriage. Solomon mystically said, "A wife will be prepared for a man by God." The man is Christ, and the wife is the church that is a wife in love and a virgin in innocence. Do not let him whom God has drawn to the Son be separated by persecution, distracted by extravagance, ravaged by philosophy, tainted by Manichaeus, perverted by Arius, or infected by Sabellius. God has joined; let not a Jew separate. All who desire to defile the truth of faith and wisdom are adulterers.… Come, Lord Jesus, to find your bride not tainted or polluted. She has not defiled your house or disregarded your commandments. Let her say to you, "I found him whom my soul loved." Let her lead you into the house of wine. Wine makes glad the heart of man. Let the Spirit saturate her. Let her recognize the mystery and speak the prophecy.

Who are we to say that someone commits adultery in taking another woman after he puts away his wife, and that another who, in doing this, does not commit adultery? The Gospel says that everyone who performs such an act commits adultery. If everyone who marries another woman after the dismissal of his wife commits adultery, this includes the one who puts away his wife without the cause of immorality and the one who puts away his wife for this reason.

Everyone who divorces his wife and marries another commits adultery, and he who marries a woman divorced from her husband commits adultery. What he foretold concerning the law that must never be violated, he confirms with one example taken from it, so that from this one example they may learn that he came not to abolish but to fulfill the decrees of the law. For a fuller exposition of this testimony, let anyone who desires to see it search not our works, but the writings of the greater authorities. For the most blessed fathers, Augustine in the first book of "On the Sermon on the Mount," Jerome, and Ambrose in their commentaries on the Gospels of Matthew and Luke, and indeed many others in their various works have more than sufficiently discussed it.

But lest they should suppose that in His words, the Law and the Prophets were until John, He preached the destruction of the Law or the Prophets, He obviates such a notion, adding, And it is easier for heaven and earth to pass, than one tittle of the law should fail. For it is written, the fashion of this world passeth away. (1 Cor. 7:31.) But of the Law, not even the very extreme point of one letter, that is, not even the least things are destitute of spiritual sacraments. And yet the Law and the Prophets were until John, because that could always be prophesied as about to come, which by the preaching of John it was clear had come. But that which He spoke beforehand concerning the perpetual inviolability of the Law, He confirms by one testimony taken therefrom for the sake of example, saying, Whosoever putteth away his wife, and marrieth another, committeth adultery: and whosoever marrieth her that is put away from her husband, committeth adultery; that from this one instance they should learn that He came not to destroy but to fulfil the commands of the Law.

But that the Law spoke imperfectly to the imperfect is evident from the following. For example, the Law, on account of the hardheartedness of the Jews, gave a decree concerning the dissolution of marriage, namely: a husband, if he came to hate his wife, had the right to divorce her, so that nothing worse would happen. For the Jews, being inclined to murder and bloodthirsty, did not spare their closest relatives, so that they even slaughtered their own sons and daughters as sacrifices to demons. But this is a deficiency and imperfection of the Law. That was the time for such legislation, but now a different, more perfect teaching is needed. Therefore I say: whoever divorces his wife except for adultery and marries another commits adultery. Therefore there is nothing surprising if I teach about non-possessiveness, even though the Law says nothing clearly about it. Behold, the Law indifferently gave a commandment about marital divorce, to prevent murder among the Jews; but I, training My listeners toward the highest perfection, forbid divorce without a justifiable reason, and I command this not in opposition to the Law, but so that there would be no murders between husbands and wives. And I confirm this when I teach that spouses should care for one another and cherish each other as their own members. The Law also desired this, but since the listeners were imperfect, it ordained the dissolution of marriage so that, at least under such a condition, husband and wife would spare each other and not rage against one another.
So, Christ confirmed all the requirements of the Law; and therefore He said well that it is impossible for one tittle of the Law to perish. For how could it have perished, when Christ fulfilled it (the Law) in a better form?

For that to the imperfect the Law spoke imperfectly is plain from what he says to the hard hearts of the Jews, "If a man hate his wife, let him put her away," (Deut. 24:1.) because since they were murderers and rejoiced in blood, they had no pity even upon those who were united to them, so that they slew their sons and daughters for devils. But now there is need of a more perfect doctrine. Wherefore I say, that if a man puts away his wife, having no excuse of fornication, he commits adultery, and he who marrieth another commits adultery.

Third, regarding the duration of the Law according to the law of nature and the conjugal bond, he adds: Everyone who dismisses his wife and marries another commits adultery: first, because he cannot dismiss the first except for the sole cause of fornication, according to Matthew nineteen: "Whoever dismisses his wife except for fornication and marries another commits adultery." Second, because for whatever cause he dismisses her, it is not lawful for him, while she lives, to marry another, and this according to the law of nature divinely instituted in the formation of man; Genesis two: "A man shall leave his father and mother," etc. And this is what dictates that "matrimony is the union of a man and a woman, retaining an indivisible manner of life"; which also dictates that it is an indissoluble bond. - And therefore he adds: And he who marries a woman dismissed by her husband commits adultery. And the reason for this is that the wife belongs to him whose she first was, however much she may seem to be separated; whence the Apostle, Romans seven: "The woman who is under a husband, while the husband lives, is bound to the law. Therefore, while the husband lives, she shall be called an adulteress if she has been with another man." And therefore Jeremiah three: "If a man dismisses his wife, and she, departing from him, marries another man, shall he return to her again? Shall not that woman be polluted and contaminated?" - It should be noted, however, that although no mention had been made of wives, the Lord nevertheless, wishing to show the permanence of the Law with regard to morals and its passing with regard to ceremonials and judicials, gives the example of matrimony, because in it the bill of divorce was given. And the law of matrimony is confirmed in the Gospel as moral law, and the bill of divorce is rejected; whence Matthew nineteen: "Moses commanded to give a bill of divorce and to dismiss. He said to them: Because Moses, on account of the hardness of your hearts, permitted you to dismiss your wives."

From these things, therefore, it is gathered how the Law remains, how it is abolished, how it is fulfilled, and nevertheless the arrogance of the Pharisees glorying in the letter of the Law is refuted.
