There was no physical church in the beginning like those that we have now and those built over the centuries since the time of Jesus.
There is organization and hierarchy all over the NT that points to a Church and not just a loosely connected group of individualists. There is a concerted effort to insure unity of the community and consistency in doctrine and theology.
The Church has grown from those small groups gathered in one another’s homes or in some hidden area safe from discovery and prosecution.
It is silly to try to point to a physical church in the Bible. The NT is the beginning not the entire history.
My faith is based on the teachings of Jesus in the NT, nothing that comes afterward is part of my religion
