You know what I think, The Scotsman ? I think the society is waiting for the generation who would understand the significance of 1914 to die away.
I totally agree.
By the time they change this some will point to the "generation" change of '95 (wow 13 years ago) as say something inane like "didn't they change the 1914 teaching YEARS ago.
The 2520 "day" 607 - 1914 stuff hasn't (to my knowledge - I left in '99) been in any frontline bible study book since the "Live Forever" book which was replaced by the "Knowledge" book () in '95
Another 15 to 20 years and they will be ready to do it.
2034 at the latest.
