Most Christians in Europe know these facts, not as a consequence of studying Eastern Orthodoxy, but as a result of studying the Roman Empire in-depth.
The idea therefore of a Corporation Church, establishing itself in a Fixed geographical location, with buildings, assets, censers (incense), altars, and statues or paintings is simply absurd. And scholars who study the origins of Christianity never make the claims to the contrary, the one exception being the Vatican. The Christians were constantly under threat, constantly on the run, and constantly in fear for their lives.

Is it a building? Or is it the people?
Not one time in scripture is the church referred to as a building but the name of God’s people. The idea of going to church was developed later.
