NOT FORMER:
I have been out for years. Nobody in the congregation is supposed to speak to a disfellowshipped person, so I do not recall a disfellowshipped person going out in the ministry.
As far as whether a reinstated person holds the same ‘esteem’ held before: generally I would say it depends. I would say No at least for the first year for people to warm up to them. If it’s somebody’s family member in some elder’s extended family - it might be like nothing much happened at all.. Whereas somebody else in the hall could still be shunned to some degree even after being reinstated.
Unfortunately, this is a cult-like religion with class distinctions that shouldn’t exist in the first place - so therefore some people are viewed better than others. I’m a ‘Fader’and was never even disfellowshipped but I swear that some people from certain families were viewed better.. My ‘sin’ was that I worked and didn’t pioneer.🤷🏻♀️
When you ask if a formerly DF’d person could rise to ‘greater heights’, I’m assuming you mean can they be an elder. I can’t say for certain but if many many years passed and the person is an older person - I suppose it might not matter if they were DF’d and reinstated as a teenager.
