I read this story in the paper and it made me chuckle a bit:
'A priest's Sunday service turned into a [M]ass brawl when he attacked one of his congregation. fr Victor Jimeno, of Valencia, slapped a man who spat out a communion wafer [*cough* the Body of Christ], sparking a fight. 'I know we are supposed to turn the other cheek but Fr Victor felt what this man needed most was vengeance, not forgiveness,' said one witness.'
And a Bible passage to suit:
Arise, O Lord! Deliver me, O my God! Strike all my enemies on the jaw; break the teeth of the wicked ~ Psalms 3:7
