The 1970s was like a Watchtower Vatican II for JWs. I was an elder back then and remember some of the open Bible discussions we had in the friends' homes. Many of us used the New English Bible rather than the NWT as the NEB was easier to understand. Had Ray Franz been allowed to continue the needed reforms the Org. would be a much different religion than it is today and I might not have left in 1984. But the reactionaries won out, reform was stopped, Ray was DFd, and the purges that followed caused liberal elders like myself to see there was no future in JWism and depart.
Hopefully what happened in the World Wide Church of God will eventually take place in the Watchtower.
