What we call churches today are merely the buildings in which we assemble.
WE ARE THE CHURCH. Believers are the Church, not some building or teachings.
I can not argue with that. I think you are right.
From my limited knowledge, the idea of the big organized church started when Rome adopted Christianity (~300 AD) and all these temples in Rome were converted. Unemployed priest from the temple of Jupiter becomes Christian priest (LOL)... Why many of the early churches are Roman style basilica’s...
Heck, early Christians were persecuted and hardly wanted to advertise their faith.
