The recent movie The Rite is loosely based on a (supposedly) nonfiction book that was published two years ago, The Rite: The Making of a Modern Exorcist by Matt Baglio. The book is about an American priest who spent his sabbatical year in Italy training to be an exorcist.
As Laura Miller explains in “Eat your saints, purge your demons,” Salon, March 27, 2009:
Father Gary Thomas, Baglio’s trainee exorcist, half fell into the job; he volunteered when, in 2004, the Vatican asked every Catholic bishop to appoint an official exorcist to his diocese. This startling development can be explained by the fact that for the past decade Italy has been gripped by an intermittent satanic ritual abuse panic similar to the hysteria that swept through the U.S. in the 1980s.
