Really, without understanding the MYSTERY DOCTRINE passed down from Russell to Franz and the necessity of a magic macguffin--one can hardly
see the need for GB pretext.
Russell was the modern day embodiment of a "last call" for the body of Christ. Rutherford did as he damn well pleased under the mantle of Russell until he threw the old boy under the bus and scuttled his interpretations.
Judge Rutherford was the mouthpiece and the pretext of Faithful and Discreet slave was all he needed.
The rulership of Franz/Nathan Knorr was a symbiosis using Governing Body in a pincer movement of headship and Prime Minister.
The crazy position in which Franz placed the reputation of JW's in modern times was ghastly!
The legal and political in-fighting staged a coup and brought down the power of the President and his Prime Minister in 1972.
Fred Franz was a figure head like Her Majesty in Great Britain.
Now, the tail wags the dog. Oh, and it barks and barks and barks.
