Back in the late 1800s, the doctrine - absurdly false as it was - had more consistency than its replacement doctrine after 1914. I'm referring to the version before today's were you had 1914 + a generation. Here's the reason:
- The end times were from 1799-1914.
- Armageddon was from 1874-1914.
- The Millennium was to start at 1914.
The inconsistency comes when they dropped the Millennium from 1914. If you recall the doctrine of Type/Anti-Type, Nebuchadnezzar was prophesied to go insane for 7 'times' then regain his sanity AFTER the 7 times were over. Back then, in the 19th century, that had some consistency since JW doctrine held that the nations would survive (somewhat) right into the (1914+) Millennium and be blessed by it.
But then they changed the doctrine separating 1914 from the Millennium and, more importantly, claimed that man-made disasters started intensifying since then.
So how would 'typical' Nebuchadnezzar, who regained his sanity after his 7 times, be compared to the 'anti-typical' nations (Which he prophetically represented.) who actually got worse after their 7 times?
