Oz:
I think it's a good example of how language and concepts accepted by a group of believers can be extended to support an authoritarian structure that uses these same words but for a different purpose.
For example, it's one thing if you personally decide to 'disfellowship' someone from your life or, on the basis of some kind of change, either theirs or your own perspective, you personally decide to 're-instate' them...all according to your own conscience.
It's very different when someone is 'disfellowshipped' from a community on the basis of the conscience of 3 men acting in secret according to a secret (Elder's Book) law.
Thanks for the great find!
