I know it is not often proper to answer a question with a question, but the answer is Any Church that Follows the New Testament.
as Jude wrote
Beloved, while I was giving all diligence to write unto you of our common salvation, I was constrained to write unto you exhorting you to contend earnestly for the faith which was once for all delivered unto the saints
Once for all. To me means that there is no more scripture that that written in the 1st century.
So any that follows that teaching is The Church
That’s fine! I was looking for an answer, and that’s a good one.
I’m saying there should be some standard that we can use to tell who is who.
