1 Corinthians 6:15

“Know ye not that your bodies are the members, of Christ, etc.] The whole persons of God’s elect were chosen in Christ, and given to him, and made one with him, their bodies as well as their souls; and both are redeemed by him, and, in union with him, are members of his body, of his flesh, and of his bones: shall I then take the members of Christ, and make them the members of an harlot? God forbid. Signifying, that it is a most absurd, indecent, abominable, and detestable thing, that the bodies of the saints, which are the members of Christ, should be joined in carnal copulation with an harlot.”

“Resuming the thought in Co1 6:13, "the body is for the Lord" (Co1 12:27; Eph 4:12, Eph 4:15-16; Eph 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].”

It is, that we as Christians are united to Christ (compare the notes at John 15:1 ff); and that it is abominable to take the members of Christ and subject them to pollution and sin. Christ was pure - wholly pure. We are professedly united to him. We are bound therefore to be pure, as he was. Shall that which is a part, as it were, of the pure and holy Saviour, be prostituted to impure and unholy embraces? God forbid! - See the note at Romans 3:4. This expresses the deep abhorrence of the apostle at the thought. It needed not argument to show it. The whole world revolted at the idea; and language could scarcely express the…”

“6:15-17 To be a Christian is to be spiritually joined to Christ in both life and death (cp. Rom 6:3-11). As a result, believers’ bodies have become parts of Christ (cp. 1 Cor 12:12-28; Rom 12:4-5). This spiritual union (cp. John 14:20; 17:21-23) means that they are not free to violate their bodies by physical union with a prostitute.”
