I think I should have qualified my " those at the top", I was referring to their Legal Advisers , and the Writing Department, who work hand in glove. Those guys, along with their Financial Advisers, know full well it is not "The Truth".
As for the Figure Heads, the Governing Body, how much they believe, and how much they know is bullshit, probably varies by member. All came up through the ranks, many life long believers, whatever, they must have a great problem with Cognitive Dissonance within themselves.
I remember well two remarks made to me , one by a London Bethel Boy, who said " The nearer you get to the top of things, the more you realise their is no "Spirituality" there, there is none in Bethel", the other was a guy who worked in the new York H.Q , in Brooklyn, as it was at the time, and he told me, " I pass the Governing Body's Committee Room in my work there, you should hear the shouting and arguments that I hear !"
