In this paragraph the apostle gives them direction in a case which must be very frequent in that age of the world, especially among the Jewish converts; I mean whether they were to live with heathen relatives in a married state. Moses's law permitted divorce; and there was a famous instance in the Jewish state, when the people were obliged to put away their idolatrous wives, Ezr 10:3. This might move a scruple in many minds, whether converts to Christianity were not bound to put away or desert their mates, continuing infidels. Concerning this matter the apostle here gives direction. And,

I.In general, he tells them that marriage, by Christ's command, is for life; and therefore those who are married must not think of separation. The wife must not depart from the husband (Co1 7:10), nor the husband put away his wife, Co1 7:11. This I command, says the apostle; yet not I, but the Lord. Not that he commanded any thing of his own head, or upon his own authority. Whatever he commanded was the Lord's command, dictated by his Spirit and enjoined by his authority. But his meaning is that the Lord himself, with his own mouth, had forbidden such separations, Mat 5:32; Mat 19:9; Mar 10:11; Luk 16:18. Note, Man and wife cannot separate at pleasure, nor dissolve, when they will, their matrimonial bonds and relation. They must not separate for any other cause than what Christ allows. And therefore the apostle advises that if any woman had been separated, either by a voluntary act of her own or by an act of her husband, she should continue unmarried, and seek reconciliation with her husband, that they might cohabit again. Note, Husbands and wives should not quarrel at all, or should be quickly reconciled. They are bound to each other for life. The divine law allows of no separation. They cannot throw off the burden, and therefore should set their shoulders to it, and endeavour to make it as light to each other as they can.

II.He brings the general advice home to the case of such as had an unbelieving mate (Co1 7:12): But to the rest speak I, not the Lord; that is, the Lord had not so expressly spoken to this case as to the former divorce. It does not mean that the apostle spoke without authority from the Lord, or decided this case by his own wisdom, without the inspiration of the Holy Ghost. He closes this subject with a declaration to the contrary (Co1 7:40), I think also that I have the Spirit of God. But, having thus prefaced his advice, we may attend,

1.To the advice itself, which is that if an unbelieving husband or wife were pleased to dwell with a Christian relative, the other should not separate. The husband should not put away an unbelieving wife, nor the wife leave an unbelieving husband, Co1 7:12, Co1 7:13. The Christian calling did not dissolve the marriage covenant, but bind it the faster, by bringing it back to the original institution, limiting it to two persons, and binding them together for life. The believer is not by faith in Christ loosed from matrimonial bonds to an unbeliever, but is at once bound and made apt to be a better relative. But, though a believing wife or husband should not separate from an unbelieving mate, yet if the unbelieving relative desert the believer, and no means can reconcile to a cohabitation, in such a case a brother or sister is not in bondage (Co1 7:15), not tied up to the unreasonable humour, and bound servilely to follow or cleave to the malicious deserter, or not bound to live unmarried after all proper means for reconciliation have been tried, at least of the deserter contract another marriage or be guilty of adultery, which was a very easy supposition, because a very common instance among the heathen inhabitants of Corinth. In such a case the deserted person must be free to marry again, and it is granted on all hands. And some think that such a malicious desertion is as much a dissolution of the marriage-covenant as death itself. For how is it possible that the two shall be one flesh when the one is maliciously bent to part from or put away the other? Indeed, the deserter seems still bound by the matrimonial contract; and therefore the apostle says (Co1 7:11), If the woman depart from her husband upon the account of his infidelity, let her remain unmarried. But the deserted party seems to be left more at liberty (I mean supposing all the proper means have been used to reclaim the deserter, and other circumstances make it necessary) to marry another person. It does not seem reasonable that they should be still bound, when it is rendered impossible to perform conjugal duties or enjoy conjugal comforts, through the mere fault of their mate: in such a case marriage would be a state of servitude indeed. But, whatever liberty be indulged Christians in such a case as this, they are not allowed, for the mere infidelity of a husband or wife, to separate; but, if the unbeliever be willing, they should continue in the relation, and cohabit as those who are thus related. This is the apostle's general direction.

2.We have here the reasons of this advice. (1.) Because the relation or state is sanctified by the holiness of either party: For the unbelieving husband is sanctified by the wife, and the unbelieving wife by the husband (Co1 7:14), or hath been sanctified. The relation itself, and the conjugal use of each other, are sanctified to the believer. To the pure all things are pure, Tit 1:15. Marriage is a divine institution; it is a compact for life, by God's appointment. Had converse and congress with unbelievers in that relation defiled the believer, or rendered him or her offensive to God, the ends of marriage would have been defeated, and the comforts of it in a manner destroyed, in the circumstances in which Christians then were. But the apostle tells them that, though they were yoked with unbelievers, yet, if they themselves were holy, marriage was to them a holy state, and marriage comforts, even with an unbelieving relative, were sanctified enjoyments. It was no more displeasing to God for them to continue to live as they did before, with their unbelieving or heathen relation, than if they had become converts together. If one of the relatives had become holy, nothing of the duties or lawful comforts of the married state could defile them, and render them displeasing to God, though the other were a heathen. He is sanctified for the wife's sake. She is sanctified for the husband's sake. Both are one flesh. He is to be reputed clean who is one flesh with her that is holy, and vice vers: Else were your children unclean, but now are they holy (Co1 7:14), that is, they would be heathen, out of the pale of the church and covenant of God. They would not be of the holy seed (as the Jews are called, Isa 6:13), but common and unclean, in the same sense as heathens in general were styled in the apostle's vision, Act 10:28. This way of speaking is according to the dialect of the Jews, among whom a child begotten by parents yet heathens, was said to be begotten out of holiness; and a child begotten by parents made proselytes was said to be begotten intra sanctitatem - within the holy enclosure. Thus Christians are called commonly saints; such they are by profession, separated to be a peculiar people of God, and as such distinguished from the world; and therefore the children born to Christians, though married to unbelievers, are not to be reckoned as part of the world, but of the church, a holy, not a common and unclean seed. "Continue therefore to live even with unbelieving relatives; for, if you are holy, the relation is so, the state is so, you may make a holy use even of an unbelieving relative, in conjugal duties, and your seed will be holy too." What a comfort is this, where both relatives are believers! (2.) Another reason is that God hath called Christians to peace, Co1 7:15. The Christian religion obliges us to act peaceably in all relations, natural and civil. We are bound, as much as in us lies, to live peaceably with all men (Rom 12:18), and therefore surely to promote the peace and comfort of our nearest relatives, those with whom we are one flesh, nay, though they should be infidels. Note, It should be the labour and study of those who are married to make each other as easy and happy as possible. (3.) A third reason is that it is possible for the believing relative to be an instrument of the other's salvation (Co1 7:16): What knowest thou, O wife, whether thou shalt save thy husband? Note, It is the plain duty of those in so near a relation to seek the salvation of those to whom they are related. "Do not separate. There is other duty now called for. The conjugal relation calls for the most close and endeared affection; it is a contract for life. And should a Christian desert a mate, when an opportunity offers to give the most glorious proof of love? Stay, and labour heartily for the conversion of thy relative. Endeavour to save a soul. Who knows but this may be the event? It is not impossible. And, though there be no great probability, saving a soul is so good and glorious a service that the bare possibility should put one on exerting one's self." Note, Mere possibility of success should be a sufficient motive with us to use our diligent endeavours for saving the souls of our relations. "What know I but I may save his soul? should move me to attempt it."

For what knowest thou, O wife - You that are Christians, and who have heathen partners, do not give them up because they are such, for you may become the means of saving them unto eternal life. Bear your cross, and look up to God, and he may give your unbelieving husband or wife to your prayers.

For what knowest thou, O wife,.... These words may be understood, as containing a reason either why the believing party should be easy at the departure of the unbeliever, after all proper methods have been used in vain to retain him or her; taken from the uncertainty and improbability of being of any use to them, to bring them to the knowledge of Christ, and salvation by him; "for what knowest thou, O wife"; thou dost not know, thou canst not know, thou canst not be sure,

whether thou shall save thy husband? be the means of bringing of him under the means of grace, and so of his conversion and salvation; there is no likelihood of it, since he is such an implacable enemy to Christ, and so bitterly averse to the Gospel, and the ordinances of it; and therefore since he is determined to separate, even let him go: or else, as rendering a reason why the believer should seek for peace and reconciliation, and by all means, if possible, continue to dwell with the unbeliever; taken from hopes of being serviceable under a divine influence and blessing, for their spiritual and eternal good, the wife for the good of the husband; by whose conversation he may be won over, and prevailed upon to entertain a better opinion of the Christian religion; to take a liking to the Gospel, and to attend upon the ministry of the word, which may be made the power of God unto salvation to him:

or how knowest thou, O man, whether thou shall save thy wife; this may possibly be done, in the same manner as now suggested: persons in such a relation have often great influence upon one another, and are by divine Providence often great blessings to each other, in things spiritual as well as temporal. This puts me in mind of a case related by the Jewish doctors (a):

"it happened to a holy man that he married a holy woman, and they had no children; say they, we are of no manner of profit to the blessed God; they stood up and divorced one another; he went and married a wicked woman, and she made him wicked; she went and married a wicked man, "and she made him righteous";''

or, to use the apostle's phrase, "saved him".

(a) Bereshit Rabba, sect. 17. fol. 14. 4.

What knowest thou but that by staying with thy unbelieving partner thou mayest save him or her? Enforcing the precept to stay with the unbelieving consort (Co1 7:12-14). So Ruth the Moabitess became a convert to her husband's faith: and Joseph and Moses probably gained over their wives. So conversely the unbelieving husband may be won by the believing wife (Pe1 3:1) [CALVIN]. Or else (Co1 7:15), if thy unbelieving consort wishes to depart, let him go, so that thou mayest live "in peace": for thou canst not be sure of converting him, so as to make it obligatory on thee at all costs to stay with him against his will [MENOCHIUS and ALFORD].

save--be the instrument of salvation to (Jam 5:20).
