Welcome to the forum Stumpy,
Now that you reviewed the WTS doctrines such has the Heavenly return of JC in 1884 and then 1914.
the bogus calculation of mankind's existence of 6000 years used twice 60 years apart, the second time to create
the significant date of October of 1975.
That should confirm that the WTS and its leaders were pressed to create fictitious doctrines to attract attention to the literature of what the WTS published and also to incite fear to influencer its members to distribute the WTS's literature to the public.
This commercial agenda was acclaimed to be Jehovah's will and purpose and all of the leaders of the WTS Corporation had self proclaimed that they had god's solemn backing as preaching " The Truth".
From out that agenda people were strategically mentally indoctrinated that what they are doing has god's approval and they were to be duly rewarded from out of those personal efforts.
There was an apparent fraud carefully hidden in the process by selecting only bible Scriptures that would support the organization's literature proliferation agenda, leaving out any bible scriptures that would not.
Perhaps there was some possible reasons why that no other Christian based religion has proclaimed what the WTS has done, from out that one can see the WTS's own inherent corruption .
