 Now the body is not for sexual immorality, but for the Lord. And the Lord for the body. And God both raised up the Lord and will also raise up his power. Do you not know that your bodies are members of Christ? Shall I then take the members of Christ and make them members of a harlot? Certainly not. Or do you not know that he who is joined to a harlot is one body with her? For the two, he says, shall become one flesh. It goes all the way back to Genesis.
