Cedars, I appreciate your observation that:
The tumultuous period in the organization’s history between 1914 and 1919 thus becomes the focus of doctrine perhaps more than ever before. There is no longer a “seamless” transition from the time of the apostles through to today. Prior to 1914, there was NO “organized channel” on the Earth. By 1919, one had been suddenly and miraculously formed – by none other than Christ himself.
This is apt. And it explains why 1914 is thatthing JWs believe. It is the central doctrine, without which they cannot exist. Christians think Christians are all about the death and resurrection of Christ. JWs think Christians are all about 1914.
1914 is their Trinity doctrine: it cannot ever be changed.
