excerpt from a yahoo news/time.com article.

"The course would bring in experts - experts in satanic cults, experts in criminology, they even had a psychiatrist come in to talk to the priests about the differences between the various mental illnesses that could be confused for demonic possession vs. what the church says is actually demonic possession. (See photos of Pope Benedict XVI.)"

that's about right.  especially with this business of upholding the excommunication of a brazilian 9 year old (and her mother, and her doctors) who had a life-saving abortion after becoming pregnant with twins being repeatedly raped by her stepfather - but not excommunicating the step father.  uhhuh.  that's pretty much your definition of demonic right there.
