We're called to rebuke sinners.
2 Timothy 4:2Preach the Word; be prepared in season and out of season; correct, rebuke and encourage with great patience and careful instruction.
Even God has occasionally lost patience with the his chosen people and had to correct them in order to turn them back to the correct path. How much patience must the Church have with a unrepentant and arrogant sinner.
I am not so good at quoting scripture but I recall that Paul had a few words to say about tolerating the presence of those whom habitually sin and will not repent.
