1 Corinthians 7:12

12.To the rest I say Bythe 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?
