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).
15 Ne savez-vous pas que vos corps sont des membres de Christ? Prendrai-je donc les membres de Christ, pour en faire les membres d'une prostituée?
