Your last paragraph is about clergy but about submitting to the rulers in each town/region, etc. These are not clergy, they are rulers.
Your last paragraph is NOT about clergy
There is not one clue in any of these citations from which you can build a doctrine of establishing a clergy of priests, nor of superseding the authority over a local church other than spiritual elders answering directly to The Head Jesus on the one hand, and accountability to the congregation on the other. So take your licks and quit on this approach.
Realize that catholicity sprang out of Irenaus and others like his fellow priest-makers to start grabbing power not authorized in the Bible.
And, of course, that is also why this priestly class doesn't want any back-channel communication of the Holy Spirit with the "lay" constituent through reading and applying such things as Jesus has commanded in it, without priestly censorship.
