There is no such thing as "demonic possession." These days, we call that Paranoid Schizophrenia. You give me someone who is supposedly "possessed," and I'll admit him to a psychiatric facility, where he'll get some Thorazine, Zyprexa, and some intensive psychotherapy, and I guarantee within a month he'll no longer be "possessed." And as for the so-called "Amityville Horror:" I had an opportunity to talk to the medical examiner from that incident (it happened in New York state, and that particular doctor, a pathologist, had moved to Ohio back in the mid-1980s). He told me that it was a fairly conventional multiple murder, and there were no "supernatural" aspects, other than the murderer was probably psychotic and heard voices he interpreted as being from God or the devil. It was impossible to say, because the murderer was dead, too. Some hack writer, who knew what kind of books sold well, took the story, expounded on it, and turned it into a large crock of commercially viable horsesh*t. Just because a book was written by a supposed Christian doesn't make it factual. Usually digging a little deeper reveals the real facts. Christians can be just as cynical as anyone else; possibly more so, because they know how gullible some Christians can be when to comes to demons and the devil, and any book that says there are demons among us will sell like holy hotcakes. The moral: Don't believe everything you read, even if it's a best seller.
