1 Corinthians 6:15

Know ye not that your bodies are members of Christ? shall. then take away the members of Christ, and make them members of. harlot? God forbid.

'Know ye not' -'Again it is implied that they had learned this already.' (F.F. Bruce p. 64)

'your bodies are members of Christ?' -individual Christians compose the body of Christ. (1 Corinthians 12:12 ff) And we have been part of Christ's body ever since baptism. (1 Corinthians 12:13) And hence are physical bodies are lit., "limbs" for Christ. (Romans 6:16)

'and make them members of. harlot?' -

We should note that Paul here is arguing against. certain kind of fornication, that some in Corinth were attempting to justify, i.e. fornication with the temple prostitutes. Paul points out, 'When. man engages with her in her vile prostitution, she uses his body for her idolatrous worship. In the sexual act she is worshiping! And he is surrendering his body to her. His body is her tool..not only is he committing fornication, he supports and promotes the false religion this woman represents.' (McGuiggan p. 77)
