The word of God does have some strong language hither and yon.
Pride; hebrew: maggots.
Wolves leading flock into 'pasture': gangrene.
He called the pastors in Jerusalem a few choice names: wolves, graves with dead men's bones, snakes, etc..
So I guess vomit christians aint so bad. But we need to be Spirit led I believe. Ezekiel 3:26, God tells the prophet to keep mum for the people are rebellious. He would direct him when to speak.
