William Peter Blatty is best known as the author of The Exorcist but he has been in the news lately for another reason.

‘Exorcist’ Scribe Petitions Church to Remove Georgetown University’s Catholic Status

William Peter Blatty, the Academy-Award winner who wrote 1973’s “The Exorcist,” graduated from Georgetown University in 1950 and has financially supported his alma mater for years. In May of last year, though, Blatty announced he was preparing a canon lawsuit against the school. On Friday, Blatty kept his promise.

The petition submitted to Cardinal Donald Weurl, is signed by 1200 individuals, including Georgetown students and alumni. There are 198 pages from 124 witnesses that document over twenty years worth of incidents that Blatty claims prove Georgetown is only Catholic in name. With Blatty’s petition is a 120 page document prepared by the Cardinal Newman Society summarizing Georgetown’s violations of canon law.

This entire endeavor took over a year.

While most remember “The Exorcist” for its green vomit and crucifix masturbation, at heart, the blockbuster horror film (that has lost none of its power) remains one of the most pro-Christian/Catholic films ever made. It is a story where both God and the Devil are very real, and a priest who is losing his faith finds it in the evil possessing an innocent. After the power of Christ compels the demon to leave the child and possess the priest, reaffirmed in his faith, the priest sacrifices his own life to destroy the evil within him.

In an interview last year with Catholic Education Daily, Blatty was asked if he saw a parallel between “The Exorcist” and what he has witnessed happen over the last two decades to his beloved Georgetown.
