About 300yrs after the Day of Pentecost, Constantine declared Christianity the state religion of Rome. It was compulsory for everyone, pagan and christian to go to “church”. Most likely they assembled in the temples where the pagans use to worship foreign gods.
The Freemasons use to say we build temples in your minds. They new how powerful architecture could influence your thinking and the way you behave in buildings.
This would influence the behavior of Christians in buildings for the next 2000yrs. Do you feel when you go to church you are locked in to a certain way of behavior and an ORDER of service.
