Well Wulf allow me to retort,
Ok I really will disappear now
Yeah well I get the last word then, don't I? :)
"The late period you refer to is when he had basically already lost and the org started recoiling from the changes he had been pushing for."
Compare the James Book to In search of Christian freedom. The ideas expressed are basically parallel regarding reliance on conscience instead of an organization with a Talmud. This was Raymonds first attempt at a real doctrinal shift and happened post 1975. The changes in the early 70s (as you pointed out) were organizational and regarding those organizational changes as you well know the GB changes of the two thirds stuck and so did the committees. Raymond was never after the Presidency (if you may have thought that was my argument), he was after his uncle's position as chief theologian. Why did he feel he could do so? Because after 1975 he could reasonably raise the specter of 1914. But he didn't challenge the 1914 date directly (that was left for the bethelite discussions in the backroom), instead he focused on his main theological point: Christian conscience supersedes an organizations authority.
So I believe that Raymond's late GB period was his actual battle because it was a struggle for theological control of and to give a new direction to the organization.
