On The Exorcist (novel)
I am at the climactic end. The approach to the final door anyway.
The exorcist finally arrives at the scene and they are about to proceed. This newcomer seems to be the real deal, and the demon seems to agree.
However, I pause now to contemplate what exactly is happening here in the story.
There is something there. That is the entire point.
...
Fellow Christians, if ye are beset by an unfathomable evil of devilry you cannot explain, contemplate what happened anyway and how it affected you. Leave the devil to the devil for its evils, and know thyself.
To all the ages to come:
Never forget the fear these Christians felt about the word "satan". Reenact it in memory of me. However you please. There is a way of the story to guide you along if you wish to do something other than whatever it is you do.
To me, it is religious expression which horrifies outside the boundaries of Christ's grace, often compelling lost sheep back into the fold, and more often devouring them as ritual sacrifices for wild parties.
We will have a universal routine we reenact doctrinally each civil year at the center and can also be carried out at the fringes by local story chapters. That routine will be different each year purposely according to a systematic method that will be open to the public, but cryptic like a black magic puzzle box.
We will have to see how this one closes first to know much more about it than that.
