If a friend told me that he let a priest blow him to get rid of demons I think I would just stare and blink and then stare and blink and then punch him in the face.
I wouldn’t punch him, but I WOULD recommend a competent psychiatrist and/or a spiritual counselor at a more God-fearing, Bible-believing church.
Or maybe I would just have him recite P.T. Barnum’s “There’s a sucker born every minute” until he died.
