Actually most religions are fairly consistent over a long period. Since the Society has no educational moorings, no respect for it's past leadership and their writings (not to say they deserved anyone's respect) it's a free radical bouncing all over the place. It is what it is now in this moment........ but not later on.
It's become a religion with no past and in a basic sense no real future.
Contrast the JW's with the Catholics or Mormons even with all of their wack-a-doodle beliefs and you have a religion that celebrate's it's past, educate's their followers.......... not only encouraging higher learning....... they even have their own universities, it encourages careers, provides assisted living options for their seniors, and supports a robust family life. That's a religion that will weather any storm or scandal and survive intact into the future.
