These days it is what ever the fuck it wants to be in order to keep the dumb-asses paying up and the victims keeping quiet about the kiddie fiddlers.
It’s based on a book that belongs on the same bookshelf as books about the Ancient Greek and Ancient Roman religions but then again it’s resulted on a lot of money being wasted on building churches and paying for religious indoctrination. Hell if we had spent that kind of money on cancer research we’d likely have whipped cancer long ago!
I would say it's a church religion...most people who claim to be Christian, don't live their lives according to the book that inspired the religion. Instead, they cling to the ideas their respective churches proselytize even those the ideas arent supported by the book.
