But and if thou marry. — Better, If, however, thou hast married. The teaching here is not for some who will, after this advice, persist in marrying, but the reference is still to those who are actually married, and a further and clearer statement to them that the question is not one of sin, but merely of desirability.
If a virgin marry. — In the original it is emphatically “If the virgin have married.” It is possible that in the letter from Corinth some particular case was referred to in which a Christian parent had scruples as to allowing his daughter to marry, and while dealing, in reply, with the subject generally, the Apostle refers immediately here to the particular case which had given rise to the inquiry. He says that if she have married she will have committed no sin; but that she and those who, like her, have married, will have troubles in the flesh, i.e., earthly troubles. It is not a spiritual question.
But I spare you. — This might, at first sight, seem to imply that he does not desire to harass them by any detail of their troubles just referred to; but the true meaning, however, is that the Apostle states his desire in giving this advice is to spare them their troubles. Matrimony will involve you in earthly troubles when the expected distress comes: therefore, in advising you to remain unmarried, my desire is to spare you them.
