Fisherman:
You don’t grasp that there are witnesses that testified to the sign that is believed to validate 1914.
I ‘grasp’ it perfectly well that it is basically impossible for the Watch Tower Society to let go of ‘607’ and ‘1914’. But the claim that there are ‘witnesses’ to something happening ‘invisibly in heaven’ is nonsense, as is the correlation with unrelated events (that started too early) in the same year. Given the number of Adventist groups that picked just about every year in the late 19th and early 20th centuries for ‘something’ to happen, it is entirely unremarkable that something significant happened in one of those years.
