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.

19. What? know ye not? &c.—Proof that "he that fornicates sinneth against his own body" (1Co 6:18).

your body—not "bodies." As in 1Co 3:17, he represented the whole company of believers (souls and bodies), that is, the Church, as "the temple of God," the Spirit; so here, the body of each individual of the Church is viewed as the ideal "temple of the Holy Ghost." So Joh 17:23, which proves that not only the Church, but also each member of it, is "the temple of the Holy Ghost." Still though many the several members form one temple, the whole collectively being that which each is in miniature individually. Just as the Jews had one temple only, so in the fullest sense all Christian churches and individual believers form one temple only. Thus "YOUR [plural] body" is distinguished here from "HIS OWN [particular or individual] body" (1Co 6:18). In sinning against the latter, the fornicator sins against "your (ideal) body," that of "Christ," whose "members your bodies" are (1Co 6:15). In this consists the sin of fornication, that it is a sacrilegious desecration of God's temple to profane uses. The unseen, but much more efficient, Spirit of God in the spiritual temple now takes the place of the visible Shekinah in the old material temple. The whole man is the temple; the soul is the inmost shrine; the understanding and heart, the holy place; and the body, the porch and exterior of the edifice. Chastity is the guardian of the temple to prevent anything unclean entering which might provoke the indwelling God to abandon it as defiled [Tertullian, On the Apparel of Women]. None but God can claim a temple; here the Holy Ghost is assigned one; therefore the Holy Ghost is God.

not your own—The fornicator treats his body as if it were "his own," to give to a harlot if he pleases (1Co 6:18; compare 1Co 6:20). But we have no right to alienate our body which is the Lord's. In ancient servitude the person of the servant was wholly the property of the master, not his own. Purchase was one of the ways of acquiring a slave. Man has sold himself to sin (1Ki 21:20; Ro 7:14). Christ buys him to Himself, to serve Him (Ro 6:16-22).
