1 Corinthians 6:15-17

6:15 Do you not know that your bodies are members of Christ? Should I take the members of Christ and make them members of a prostitute? Never! 6:16 Or do you not know that anyone who is united with a prostitute is one body with her? For it is said, “The two will become one flesh.” 6:17 But the one united with the Lord is one spirit with him.

Worse still, the leaders and the officials have been at the forefront of all of this!”
