Commentary on the Epistles to the Corinthians John Calvin
Commentary on the Corinthians answer, that when we are prompted by the infirmity of our flesh, we must have recourse to the remedy; after which it is the Lord's part to bridle and restrain our affections by his Spirit, though matters should not succeed according to our desire. For if a wife should fall into a protracted illness, the husband would, nevertheless, not be justified in going to seek another wife. In like manner, if a husband should, after marriage, begin to labor under some distemper, it would not be allowable for his wife to change her condition of life. The sum is this — God having prescribed lawful marriage as a remedy for our incontinency, let us make use of it, that we may not, by tempting him, pay the penalty of our rashness. Having discharged this duty, let us hope that he will give us aid should matters go contrary to our expectations.
12. To the rest I say By the rest he means those who are exceptions, so that the law, common to others, is not applicable to them; for an unequal marriage is on a different footing, when married persons differ among themselves in respect of religion; Now this question he solves in two clauses. The first is, that the believing party ought not to withdraw from the unbelieving party, and ought not to seek divorce, unless she is put away. The second is, that if an unbeliever put away his wife on account of religion, a brother or a sister is, by such rejection, freed from the bond of marriage. But why is it that Paul speaks of himself as the author of these regulations, while they appear to be somewhat at variance with what he had, a little before, brought forward, as from the Lord? He does not mean that they are from himself in such a way as not to be derived from the Spirit of God; but, as there was nowhere in the law or in the Prophets any definite or explicit statement on this subject, he anticipates in this way the calumnies of the wicked, in claiming as his own what he was about to state. At the same time, lest all this should be despised as the offspring of man's brain, we shall find him afterwards declaring, that his statement are not the contrivances of his own understanding. There is, however, nothing inconsistent with what goes before; for as the obligation and sanctity of the marriage engagement depend upon God, what connection can a pious woman any longer maintain with an unbelieving husband, after she has been driven away through hatred of God?
14. For the unbelieving husband is sanctified He obviates an objection, which might occasion anxiety to believers. The relationship of marriage is singularly close, so that the wife is the half of the man — so that they two are one flesh — (1 Corinthians 6:16) — so that the husband is the head of the wife; (Ephesians 5:23;) and she is her husband's partner in everything; hence it seems impossible that a believing husband should live with an ungodly wife, or the converse of this, without being polluted by so close a connection. Paul therefore declares here, that marriage is, nevertheless, sacred and pure, and that we must not be apprehensive of contagion, as if the wife would contaminate the husband. Let us, however, bear in mind, that he speaks here
John Calvin not of contracting marriages, but of maintaining those that have been already contracted; for where the matter under consideration is, whether one should marry an unbelieving wife, or whether one should marry an unbelieving husband, then that exhortation is in point —
Be not yoked with unbelievers, for there is no agreement between Christ and Belial. (2 Corinthians 6:14.)
But he that is already bound has no longer liberty of choice; hence the advice given is different.
While this sanctification is taken in various senses, I refer it simply to marriage, in this sense — It might seem (judging from appearance) as if a believing wife contracted infection from an unbelieving husband, so as to make the connection unlawful; but it is otherwise, for the piety of the one has more effect in sanctifying marriage than the impiety of the other in polluting it. Hence a believer may, with a pure conscience, live with an unbeliever, for in respect of the use and intercourse of the marriage bed, and of life generally, he is sanctified, so as not to infect the believing party with his impurity. Meanwhile this sanctification is of no benefit to the unbelieving party; it only serves thus far, that the believing party is not contaminated by intercourse with him, and marriage itself is not profaned.
But from this a question arises — "If the faith of a husband or wife who is a Christian sanctifies marriage, it follows that all marriages of ungodly persons are impure, and differ nothing from fornication." I answer, that to the ungodly all things are impure, (Titus 1:15,) because they pollute by their impurity even the best and choicest of God's creatures. Hence it is that they pollute marriage itself, because they do not acknowledge God as its Author, and therefore they are not capable of true sanctification, and by an evil conscience abuse marriage. It is a mistake, however, to conclude from this that it differs nothing from fornication; for, however impure it is to them, it is nevertheless pure in itself, inasmuch as it is appointed by God, serves to maintain decency among men, and restrains irregular desires; and hence it is for these purposes approved by God, like other parts of political order. We must always, therefore, distinguish between the nature of a thing and the abuse of it.
Else were your children It is an argument taken from the effect — "If your marriage were impure, then the children that are the fruit of it would be impure; but they are holy; hence the marriage also is holy. As, then, the ungodliness of one of the parents does not hinder the children that are born from being holy, so neither does it hinder the marriage from being pure." Some grammarians explain this passage as referring to a civil sanctity, in respect of the children being reckoned legitimate, but in this respect the condition of unbelievers is in no degree worse. That exposition, therefore, cannot stand. Besides, it is certain that Paul designed here to remove scruples of conscience, lest any one should think (as I have said) that he had contracted defilement. The passage, then, is a remarkable one, and drawn
