It happened with WWCOG...
You're right it did. The leadership publically recanted alot of their bizarre teachings, apologized to the rank and file, became more mainstream and far more tolerable of what you can celebrate and believe------and promptly lost 3/4 of their membership.
People who are members of religions like the WWCoG, the WTS, the Church of Jesus Christ of Latter Day Saints, Scientology, or Islam, do not do well with drastic changes in their beliefs. It makes them very uncomfortable because the reason they belong to the group in the first place is because it's "different" than most other religions and it makes them feel special. To have that "special" feeling taken away can easily be interpreted as a threat to your spirituality and many people just can't handle it.
I can't see 1914 going anywhere any time soon although they don't promote it anywhere near as often as they used to. As has already been mentioned on here: they can't get rid of it without getting rid of the doctrine that Jesus chose these guys as the F&DSC in 1919 and if they do that, they lose their scriptural authority to rule over 6.5 million people and that is something they will never do.
Let's face it: Their latest interpretation as to what "this generation" means, is a pathetic joke and does nothing but reveal their desperate attempt to hold onto their power for as long as possible. In over 140 years, they've never apologized for anything no matter how many lives they've destroyed or how f*cking ridiculous some of their doctrines have been. They just don't give a shit. And they never will.
