1 Corinthians 6:15 (ESV)

15 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 prostitute? Never!

After having countered the Corinthians’ abuse of two popular sayings (1 Corinthians 6:12–14), Paul offers three further considerations. These are given in an accusatory way, in the form of three questions that begin with the words, Do you not know…? (1 Corinthians 6:15–16, 1 Corinthians 6:19).

With the first question, Paul reminds the Corinthians of a truth that they have certainly been taught, and to which he will return in chapter 12. This is, namely, that the church is the body of Christ.

A person cannot be joined to the body of Christ and to the body of a prostitute at the same time. When a church member joins himself to a prostitute, he is in effect severing himself from Christ (the Greek word, which the ESV renders as take, normally implies that something is taken away).
