Randall Watters presents the fascinating backstory of the "Aid Book", and the brouhaha surrounding it, in this article:
"The Watchtower Bible and Tract Society: The Critical Years 1975-1997"
So far it seems the project to research and write the "Aid to Bible Understanding" revealed serious doctrinal and institutional flaws that the GB wanted to preserve nonetheless.
It seems what Ray Franz and his team were learning, and were largely blocked from presenting:
- Legalism is apostasy (the making and keeping of many rules)
- Salvation is by faith not works
- A right and clean standing with God is not earned but rather imputed as a "free gift"
- The liberating gospel of grace (Romans and Galatians)
- The "Good News" or gospel message is about a lot more than the Watchtower's reductionist Kingdom (future, physical paradise on this earth)
- The two class system is unbiblical ("one hope", "one flock")
- Autocracy (and hierarchy?) is unbiblical
- Jerusalem was destroyed in 587-586 BC and not 607 BC (1914 date and calculations false)

Are you able to find anything useful that slipped through into the "Aid Book" which either made it into the Insight Books or was dropped entirely?
