A preview of a classic

I went with my family to a job site (deconstructing a torn barn) when we came to an estate sale. Of course, the one thing that got my attention were the books. I wasn't sure there would be anything getting my attention (the person that passed away was an elderly woman), surprisingly, there were 3 books (all classics). I'd like to talk about one in particular.

I once heard that this is the original Christian horror story (it first came out even before Stephen King's debut novel Carrie). In today's standards (which are faulty and subjective at best), this would NOT be Christian in any regards.
You seen the movie? Besides the notoriously frightening head-twisting scene and the girl's transformation, there was a whole lot of graphic language, disturbing violent content, and even graphic sexual material (such as the possessed girl actually slamming a crucifix into her vagina and screaming out "F*** ME! F*** ME! F***ME!" and letting the blood fly).
I decided to skim parts of it and, it turns out, it's far more deprived, and, honestly, I found myself actually wanting to really get into the story.
One particular part that really sent chills down my spine (or close to it) was the girl looking at her mom and, by the control of the demon, told her religious mom that she "should let Jesus f*** you."
No, the book doesn't censor it, but it got me thinking two things:
1. The movie must have had to take some seriously heavy liberties to not seriously upset the religious community, lest the Catholic Church grade the movie "C" for condemned (like they did with the book-based movie "A Clockwork Orange").
2. The author did not let any barriers get in the way of portraying a demon realistically, graphically, and seriously.
When I read Ted Dekker's demon-possession-based horror story Adam (the first horror story to really give me the chills, ever), the demon in the story, because of the CBA (those that deem a Christian book to really be "Christian"), had to refrain from swearing at all and spoke euphemisms. The demon in The Exorcist took no such softening- it cussed, profaned, blasphemed, and even spoke sexual sacrileges. With the realism put into how the demon spoke (and yes, in the book, the demon did force the girl to masturbate with a crucifix, and the detail was quite vivid), it really impressed me.
Today, if Christian wrote something like this, they'd have to use a pseudonym and publish either through a secular channel or independently because of all the all-too-easily offended nature of today's church ("You can not believe in demons today!"), yet this reminds me of the offensive nature of the Bible- revealing the ways of the natural and spiritual worlds without barriers, without a care about how the populace would react, its purpose is to reveal the truth, not appeal to people's wishes about who they are (or it'd be far thinner). It also made me wish the CBA wouldn't exist so Christian authors could write the way they feel they could (like Dracula, which has no swearing, but is considered too "horrific" by the church to be "Christian", ridiculously enough).
If anyone should feel the entitlement to be offended at all, it should be God, not us humans who are filled with offensive sins anyway. So, I don't care about the language usage or the bizarre sexual/violent content, I can see this being the original CHRISTIAN horror story since it deals with the graphic, grotesque, disgusting, aberrant, dark, and ultimately twisted nature of pure evil... and how God Himself is the only to deal with evil itself, it doesn't provide alternative "humanist" methods, it presents a HARDCORE battle between pure good and pure evil and that relentless battle for each soul, no matter what it takes.
The next blog I write about this book will be a full review. Yes, I'm excitedly looking forward to it in the near future.
