Quotes from the Chief Exorcist:
"When the possessed dribble and slobber, and need cleaning up, I do that too. Seeing people vomit doesn't bother me."
He also condemned the Harry Potter books, saying they were dangerous because they dabbled in the occult and failed to draw a clear distinction between "the Satanic art" of black magic and benevolent white magic.
And just for the record, there is indeed an Association of Exorcists.
