I hate it when people take this verse out of context in order to further their own agenda of violence.
Matthew 10:16 Behold, I send you forth as sheep in the midst of wolves: be ye therefore wise as serpents, and harmless as doves.
Jesus was sent to gather his flock. Nothing more, nothing less. In no way did he ever say we are to make war with our brothers.
“In no way did he ever say we are to make war with our brothers.”
True, but God’s word is clear what to do with unrepentant immoral “brothers”. They are to be expelled from the church, and should not create their own “churches” that tolerate their sin.
