God will destroy anyone who destroys the unity of a congregation.

1 Corinthians 3:16-17

16 You need to remember that God is present among you (pl) as he was present in the Temple in Jerusalem. [RHQ] God’s Spirit lives within you. 17 So, just like God will destroy anyone who tries to destroy his Temple, he will destroy anyone who destroys the unity of a congregation. He will do that because he has set you, his people, apart for himself, just like he set his Temple apart for himself.
