Some may have read the whitewashed version in the Proclaimers book...but most are satisfied I'm sure with, the "fact" that Jehovah now has cleansed His organization from previous errors....
This is how it was explained to me growing up that the early Bible Students practised things that were not scriptural in the beginning but that the light gets brighter and that is why they did away with these false teachings. Although this gets back to, if the WT is spirit directed how can they make mistakes in the first place?
I once asked my mother about the early Millarite influence on the early Bible Student movement but she was not aware of this either.
