Our priest was an exorcist by accident and was not formal by the diocese. He had 2 cases.One was he drove a man to Mass because the wife said he was afraid of church.When they got outside of the church the man punched him in the mouth.Another when a man was dying and refused to see a priest.He dressed in regular closes and walked into his bedroom where he was dying.The guy started to scream and Father blessed him with Holy Water.He settled down and Father heard his last confession.Just to califly.
