And [Paul] said, “O full of all deceit and all fraud, you son of the devil, you enemy of all righteousness, will you not cease perverting the straight ways of the Lord? Acts 13:10
That sounds pretty judgmental; calling someone a son of the devil and following it up with enemy of righteousness and accusing them of perverting the ways of the Lord.
I don’t think that would gain approval in today’s church. But the man it was said to was a fake prophet, fortune telling Jew. The false prophet and fortune telling would have got him stoned in the days of the Old Testament.
Instead of such a harsh punishment, Paul said his piece and pronounced that he would be blind for a spell. And it came true!
If I called someone in my church a son of the devil, they would probably leave. But if they were a son of the devil, then that’s what needs to happen!
The church has become soft on church discipline to the point we allow ungodly spirits to inhabit the pews and make leadership decisions.
“Get behind me, Satan” (Matt 16:23) and “The Lord rebuke you” (Jude 9) should become the battle cry of the church. Just as the false prophet withstood the Gospel that Paul preached, the demonic spirit will withstand your church.
