I do not believe that it is was part of Christ's original message that anyone who did fall into the lockstep march of churchianity - would meet with eternal punishment and damnation.
I don't believe it was part of His message either, in fact I think He taught just the opposite. Doing anything in lockstep (by law or decree alone) hinders the work of the Holy Spirit, IMO. However, I dont think that walking in lockstep is what all Christians do, or even what all denominations try to do. Can't argue with the fact, though, that this is how it is percieved and experienced by some.
When it happens like this...yes. The basis of fear is in judgement, I think.This is no more than fear tactics.
