Dr. Richard Gallagher is an Ivy League-educated, board-certified psychiatrist who teaches at Columbia University and New York Medical College. …
Fighting Satan’s minions wasn’t part of Gallagher’s career plan while he was studying medicine at Yale. He knew about biblical accounts of demonic possession but thought they were an ancient culture’s attempt to grapple with mental disorders like epilepsy. He proudly calls himself a “man of science.”
Yet today, Gallagher has become something else: the go-to guy for a sprawling network of exorcists in the United States. He says demonic possession is real. He’s seen the evidence: victims suddenly speaking perfect Latin; sacred objects flying off shelves; people displaying “hidden knowledge” or secrets about people that they could not have possibly have known.
Gallagher calls himself a “consultant” on demonic possessions. For the past 25 years, he has helped clergy distinguish between mental illness and what he calls “the real thing.” He estimates that he’s seen more cases of possession than any other physician in the world.
