We've probably all seen exorcisms performed in movies and TV, but how accurate are those portrayals? Are they really as ferociously terrifying as these shows would have us believe? Where did the writers get their ideas and details about what actually takes place during an exorcism? The Roman Catholic Church has only one sanctioned procedure, and it's in the 23 pages of "The Great Exorcism Rite" contained within the Rituale Romanum. Compiled in 1614 at the request of Pope Paul V, with minor updates added in 1952 and 1999, it is still the only rite used to this day. With this sacrament guiding the Jesuit's efforts recorded in the "Exorcist's Diary" documenting the exorcism of Ronnie Hunkeler, it can be argued that this account is the inspiration for most everything portrayed in entertainment media. And therefore mostly informing what the general public has seen and knows about an authentic exorcism.
