We met with the like determination of our Lord's upon this question Matthew 5:32, only there it was (instead of committeth adultery) causeth her to commit adultery, that is, in case she married again. Here our Lord saith the like of the husband: we have the same, Mark 10:11 Luke 16:18. The reason is this: Because nothing but adultery dissolves the knot and band of marriage, though they be thus illegally separated, yet according to the law of God, they are still man and wife. Some have upon these words made a question whether it be lawful for the husband or the wife separated for adultery to marry again while each other liveth. As to the party offending, it may be a question; but as to the innocent person offended, it is no question, for the adultery of the person offending hath dissolved the knot of marriage by the Divine law. It is true that the knot cannot be dissolved without the freedom of both persons each from another, but yet it seemeth against reason that both persons should have the like liberty to a second marriage. For,
1. The adulteress is by God's law a dead woman, and so in no capacity to a second marriage.
2. It is unreasonable that she should make an advantage of her own sin and error.
3. This might be the occasion of adultery, to give a wicked person a legal liberty to satisfy an extravagant lust. But for the innocent person, it is as unreasonable that he or she should be punished for the sin of another. But what our Saviour saith here, and in the other parallel texts, is undoubtedly to be understood of husbands and wives put away not for adultery, but for other light and trivial causes, for which by the law of God no divorce is allowed.
