1 Corinthians 5:1, 2.

The congregation not only tolerated his behavior but also may have been rather proud of it. Perhaps some thought that it demonstrated how merciful and understanding God is toward imperfect humans. But Jehovah does not condone wrongdoing among his people. With such a brazen course, the man was surely damaging the good reputation of the congregation. He could also have been influencing other Christians who were associating with him.
