You show bad spirit if it hurts you to see others work for Christ without regard for what you are doing. Remember this passage in Saint Mark: 'Master, we saw a man who is not one of us casting out devils in your name; and because he was not one of us we tried to stop him.' But Jesus said, 'You must not stop him: no one who works a miracle in my name is likely to speak evil of me. Anyone who is not against us is for us'.
