I think that before I grab my book bag and head back to the hall, I'll give it a bit more time. I haven't seen anyone claim that they are not a well-organized cult that has hit on a strong, repeatable formula. When things go well they telI everyone, including themselves, that God supports them. When things go poorly, they blame the wicked system of things and claim it is further evidence of the impending doom. - Tight as a drum. Don't forget, these are the people that rationalized away the embarassment of 1914, 1975.
I don't picture any cataclysmic collapse. At best, I see a slow sinking under the weight of fase prophecy. But no time soon.
