And let me add that things go sideways when authority outside of an ekklesia is subjected upon it (other than Christ). The Church in Rome is the biggest example of this, and then came all the smaller examples. I think perhaps the biggest sin of the Roman Catholics is that they supplanted the authority of Christ with a central government (which The Romans were really good at).
So with the Roman example you then have the whole clergy-laity thing on steroids - that is, not just authority and control over one ekklesia, but many. Truly a mysterious monster indeed!
