Just to add context..

My observation is that they are a small self enclosed religious community,
tending to marry between families - a restricted gene pool...
This results in ministers being related to each other, at least by marriage, if not blood..

So it's easy to understand why & how they have to put up with each other,
and make allowances for their nastier zealots...???

Business men within their religion seem to do very well out of the network...
