Yes and CELEBRATED BY WHOM? I don't think any serious scholars take them seriously at all. The problem when we were in the 'deception' we were brainwashed into thinking that those people really were experts.
But when I was on my first 2 week Elders training school way back in 1976, our instructor told us that contrary to 'popular' belief within the organisation, the Governing Body which included Fred Franz in those days, DID NOT CONSULT some kind of ORACLE for Divine Revelation. So where did it all come from? The instructor told us that the Worldwide Brotherhood keep writing in about various understandings, and if enough write in about the same thing, they deem it as being a sign of Jehovah's 'nudging' of the Governing Body into the direction of the magority.
He also said that the COs report back ' weaknesses' in Congregations and then they write an article in the WT about it, and all the members think it is Food at the proper time. Its all a great big sham.
I always had a different feeling about the Society after that. And when Elders or others would say, Oh what a wonderful Watchtower that was, I would think what on earth are they on about?
The WTs were all a load of comlex sounding drivel, that hardly anyone would dare to question it, as it was from the 'elite faithful and discreet slave class'
Nothing was ever from Jesus our King, it was always the F&DS, who was supposed to be appointed by the Master himself. And that is how I know it IS NOT FROM OUR GOD BUT FROM THE god OF THIS WORLD.
