Church isn’t a building, it’s the people, the body of believers.

Also the word church is a pagan term that comes from kirke which means circle. The actual term used in scripture to denote believers was the Greek word Ekklesia which means called out ones. The Hebrew equivalent would be the word Qahal or in English, assembly.

The reason the word church was substituted with these correct terms was in order to keep the people in the dark and subservient to the leadership, they also prohibited the laymembers from reading scripture in their own language or reading it period (the penalty was death) in order to maintain their control and power, both economic and social.

This is why one of the translators of the Bible into English, William Tyndale, was burned at the stake.
