Yes, I've heard your thesis for many times over many years, and considering the underlying topic audience, I will not here continue to challenge.
But your point is also consistent with mine--that there exists no visible earthly catholic/universal overarching human supervisory function possessing authority and power to dictate to each and every local New Testament assembly professing fealty to The Christ of The Bible.
But thanks for your opinion. It is still up for debate.
There is only one Church founded by Christ. No Protestant sect possesses any authority. And yes, there is a visible earthly authority. It just isn’t found in any Protestant sect.
