Yet I think you are missing one important point.
The NT focuses on the work of Jesus and the early church, whose mission was to
spread the gospel to the uttermost parts of the earth.
This was a new venture, a new belief system (actually it was an old belief system turned
the right way around but people didn't understand that).
The early church had a humongous task of teaching people what the OT was really about and
how Jesus fulfilled it. God chose specific people to conduct this task, to spread this new
belief system. Those people by default could not stay in one place they were tasked with
the spreading of the gospel.
The NT early churches represent a model, a programme if you like for establishing Christianity.
We would call it church planting. But each church does need leadership.
I agree that for one person to have ultimate control, is probably not a good idea, that's where
cults spring from. But ive never been to a church where this was the set up in the UK.
Maybe you just need to put the bad experiences behind you, find a church you are
comfortable with, get on with your life and let the matter drop.
It seems to have become a bit of an obsession. Who knows maybe God wants you to be
an intinerant preacher, but one with a single message of "down with all other preachers" isn't
going to do a good job of spreading the gospel. Just saying.
ps maybe if you ever feel the need to actually spread the gospel, you could play on the
fact that you look like Captain Pickard from Star Trek. Shave the beard, get a red jumper
and it would go down a storm
