1 Corinthians 6:15-18

15You know that your bodies are parts of Christ's own body. So you must never take your body and make it join with a prostitute's body. That is like you have done it with part of Christ's body. Never let that happen!

16Anyone who makes his own body join to a prostitute becomes one body with that prostitute. You should know that. It says in the Bible: ‘The man and the woman become as one body.’

17But everyone who is united to the Lord has the same spirit as him.

18So never have sex in a wrong way! You may say, ‘If a person does a bad thing, it is not his body that does it.’ But if you have sex in a wrong way, you are doing a bad thing to your own body.
