{11} Know ye not that your bodies are the members of Christ? shall I then take the members of Christ, and make them the members of an harlot? God forbid.

(11) A declaration of the former argument by opposites, and the application of it.

People's New Testament

6:15 Know ye not that your bodies are the members of Christ? This is a doctrine emphasized by Paul. Our bodies are a part of Christ's mystical body, the Lord's holy temple, designed for the indwelling of the Spirit. How sacrilegious to take a member of Christ's body and degrade it to fornication, or to any act of licentiousness! It is a duty which a Christian owes to Christ to keep his body pure. As the arm or finger has the life of the body until cut off, so we have the life of Christ until we sever ourselves from him by sinful acts.

Scofield Reference Notes

Margin shall I

Paul does not invoke the authority of the seventh commandment, but appeals to the believer's sacredness as a member of Christ.

Jamieson-Fausset-Brown Bible Commentary

15. Resuming the thought in 1Co 6:13, "the body is for the Lord" (1Co 12:27; Eph 4:12, 15, 16; 5:30).

shall I then-such being the case.

take-spontaneously alienating them from Christ. For they cannot be at the same time "the members of an harlot," and "of Christ" [Bengel]. It is a fact no less certain than mysterious, that moral and spiritual ruin is caused by such sins; which human wisdom (when untaught by revelation) held to be actions as blameless as eating and drinking [Conybeare and Howson].

Matthew Henry's Concise Commentary

6:12-20 Some among the Corinthians seem to have been ready to say, All things are lawful for me. This dangerous conceit St. Paul opposes. There is a liberty wherewith Christ has made us free, in which we must stand fast. But surely a Christian would never put himself into the power of any bodily appetite. The body is for the Lord; is to be an instrument of righteousness to holiness, therefore is never to be made an instrument of sin. It is an honour to the body, that Jesus Christ was raised from the dead; and it will be an honour to our bodies, that they will be raised. The hope of a resurrection to glory, should keep Christians from dishonouring their bodies by fleshly lusts. And if the soul be united to Christ by faith, the whole man is become a member of his spiritual body. Other vices may be conquered in fight; that here cautioned against, only by flight. And vast multitudes are cut off by this vice in its various forms and consequences. Its effects fall not only directly upon the body, but often upon the mind. Our bodies have been redeemed from deserved condemnation and hopeless slavery by the atoning sacrifice of Christ. We are to be clean, as vessels fitted for our Master's use. Being united to Christ as one spirit, and bought with a price of unspeakable value, the believer should consider himself as wholly the Lord's, by the strongest ties. May we make it our business, to the latest day and hour of our lives, to glorify God with our bodies, and with our spirits which are his.
