I recently bought the book called 'The Rite' which is about Fr. Gary who is a Priest from California and was chosen by his Bishop to go to Rome to train as an exorcist. The book starts out with a prologue of a woman who is being exorcised and apparently has a very powerful demon within her that the Priest is struggling to release her from. The story then goes on to tell about the Fr. Gary's background and how it came that he was chosen to go take the exorcism course in Italy. I am now about two thirds of the way through the book and I have read some pretty fantastic stuff thus far regarding exorcism and the ways that people have been infested, oppressed, and possessed. Most if not all of the people who truly are experiencing some time of demonic influence in their lives have dabbled in the occult and thereby opened themselves up to the devil. There are a few cases however of people that were cursed by their parents or other family members and they are the ones that really suffer the most terrible pains and aggrevations through this demonic force that is presenting itself through them.
I know that not many people believe in Exorcism today or really even believe in demons. However, that being said, I know for a fact that there is a devil and that this type of stuff happens all the time. I remember watching a movie called Constatine a few years ago about a man who once served evil and then began to fight evil and he had a friend who didn't believe that the things he had told her was real, until one day he introduced her to it and it was as if a veil was lifted and she saw another world open up before her very eyes. I think that this is how the spirit would is derived. It is right in front of our faces, many people just brush by it and have no idea that it is there or that it even exists. And then there are those people that find themselves delving into this spirit world and they are then infected as though they caught a virus and they are not able to be freed of it until they visit someone just like Fr. Gary - an exorcist.
This world is real people, it is out there, and we need to guard ourselves against it. This is not a fantasy playground, it is not for jokes or playing around it, this is a very serious place and it seems that more and more people are getting caught up in the new age worldliness and are slowly being sucked into this ethereal battlefield designed to seal their doom.
To anyone who is interested in learning more about spiritual warfare, how to protect and guard yourself, or if you are an unbeliever and think that your living in a safe haven.. I recommend that you take a moment and buy this book - it is well worth the 15 bucks on ebay or half.com
