I would have once stated that the ability to decieve so completely must be the mark of a 'cult'. Nowadays I would more likely just state that ALL religion is delusion, some are just more focused on delusional beliefs than others.
I find it extremely curious, as regards Jehovahs Witnesses, that in only two years we hit 100 years since Jesus took that throne. Yet, this will probably not be even a minor panic for them - they know that the sheeple are blind and ignorant to such things.
It's no different in the other churches though who have been preaching rapture, end of times, or other doctrine for a lot longer. If only they would all take up the Shaker doctrines - now THAT would help reduce the ignorance over just one generation, wouldn't it?
