I was baptized in 1948. Yes, that makes me old. I lived through much of this history. I don't hold anyone responsible for my belief but myself. Nor should I. If we were taught wrongly, it was still up to us to decide to believe. I have always been what one of my friends calls a "sekptical believer." When I was an active Witness (You may have heard me at District Conventions), I questioned things. It made me unpopular sometimes. In the approach to 1975, The Watchtower Society told me to stop writing to them about it. Eventually I reached a tipping point. I do not blame the person who studied with me. He's been dead for decades. I don't blame Franz or Knorr, both of whom I knew at least somewhat personally. The fault is my own.
I doubt one can move on until they take responsibility for themselves.
Do I still have unresolved issues. Yes, I do. But, while I reject Watchtower philosophy and practice. it was my choise to enter and certainly my choice to leave. I didn't fornicate, smoke, steal, have sex with my neighbor's donkey or childen. I stopped believing things that seem very unscriptural and I rejected the self-serving, self-entitled view of elders (I was one at the time) and governing body members. In fairness, I don't know any of the current GB members except on the basis of a brief meeting with two of them. All those I knew personally are very, very dead. And they weren't all like that. John Barr (and his wife too) was a Christian in every sense - Approachable, loving, kind, concerned. That can't be said about others of them. But, none of them persuaded me to believe. I did that myself.
If our critical faculties lapse, it's not someone else's fault. It's our own.
