Half banana
High fives Orphan Crow, it's always the money when dealing with the governance of the WTBTS.
High fives back at ya, Halfbanana. :)
Of course it is all about the money. And the justification for the governance and authority to continue the money scam has been deliberately and intimately entangled up in the doctrine around 1919.
The reason for their doctrine is to obfuscate their purpose and appear like they are a 'religion' when they are not. (Unless, of course, the religious mandate is money making. Then, they are right on target with their doctrine).
It is a mistake to think that the WTS doctrine is biblically valid - it isn't - any behavior can be justified by manipulating biblical text. Any behavior. It is a waste of time to analyze biblical text when trying to figure out what the Tower boys are up to. A person can utilize their time better by examining both external and internal political events and financial events around whatever dates and/or doctrine they are putting out there.
By claiming biblical authority for the WTS money schemes, and the more twisted and changing that the doctrine can be made (*see above post by menrov), assures that those sitting up in the Tower have a line of protection around their nefarious movements. The doctrine acts as a hedge - one that catches people feet in its web and occupies them with searching inside an old book(s) to try to figure out what is going on, when the answers are to be found in the political/financial movements of the Tower boys.
As long as a person spends their time analyzing doctrine from reading a bible book, their head will be down reading and they will not look up. And they should look up. Way up. To the Tower and the boys inside that Tower.
