Moffatt(i)
15 Do you not know your bodies are members of Christ? Am I to take Christ's members and devote them to a harlot? Never!
16 Do you not know that he who joins himself to a harlot is one with her in body (for the pair, it is said, shall become one flesh),
17 while he who joins himself to the Lord is one with him in spirit.
18 Shun immorality! Any other sin that a man commits is outside the body, but the immoral man sins against his body.
