Know you not that your bodies are the members of Christ? shall I then take the members of Christ, and make them the members of a harlot? God forbid.
All Commentaries on 1 Corinthians 6:15 Go To 1 Corinthians 6
John Chrysostom
AD 407
Having passed on from the fornicator to the covetous person, he comes back to the former from the latter, no longer henceforth discoursing with him but with the others who had not committed fornication. And in the act of securing them lest they fall into the same sins, he assails him again. For he that has committed sin, though you direct your words to another, is stung even in that way; his conscience being thoroughly awakened and scourging him.
Now the fear of punishment indeed was enough to keep them in chastity. But seeing that he does not wish by fear alone to set these matters right, he uses both threatenings and reasons.
Now upon that other occasion, having stated the sin, and prescribed the punishment, and pointed out the harm which intercourse with the fornicator brought upon all, he left off, and passed to the subject of covetousness: and having threatened the covetous and all the rest whom he mentioned with expulsion from the kingdom, he so concluded his discourse. But here he takes in hand the work of admonition in a yet more terrific manner. For as he that only punishes a sin and does nothing to point out its most extreme lawlessness, produces no such great effect by his chastisement: so again, he who only abashes and fails to terrify by his mode of punishing, does not very keenly hit men of hardened minds. Wherefore Paul does both: here he abashes, saying, Do you not know that we shall judge angels? there again he terrifies, saying, Do you not know that the covetous shall not inherit the kingdom of God?
And in regard to the fornicator, he again uses this order of discourse. For having terrified him by what he had said before; first cutting him off and delivering him to Satan, and then reminding him of that day which is coming; he abashes him again by saying, Do you not know that your bodies are members of Christ? thenceforth speaking as to children of noble birth. For whereas he had said, Now the body is for the Lord, he indicates it more plainly now. And in another place as well he does this same thing, saying, 1 Corinthians 12:27 Now you are the body of Christ, and severally members thereof. And the same figure he often employs, not with the same aim, but at one time to show His love, and at another to increase their fear. But here he has employed it to startle and fill them with alarm. Shall I then take the members of Christ, and make them members of a harlot? God forbid. Nothing can be apter to strike horror than this expression. He said not, Shall I take the members of Christ, and join them on to a harlot? but what? make them members of a harlot; which surely would strike more keenly.
Then he makes out how the fornicator becomes this, saying thus, Do you not know that he that is joined unto a harlot is one body? How is this evident? For the two, says He, shall become one.
