I wonder, what will happen after 50 years, when the overlapped generation will pass?. And if you want, what will happen with this religion in 2100?, could it survive with the same lie???
I'm afraid that the 1914 nonsense is going to last for as long as it serves their purpose. As soon as they find something to replace it or as soon as they run out of ridiculous explanations or "new light" announcements, I'm sure they are going to come up with a plan to have something else substitute it.
The fact that they are now conditioning their followers to (1) get use to changes as per their saying and (2) continue hiding, destroying and/or minimizing what they have said in the past under the excuse of "new light', gives them leeway to prolong what they preach.
In other words, the 1914 nonsense isn't going away for as long as it continues being their milking cow.
