“Church” is a town-meeting word
Ekklēsia meant the citizens of a Greek city called out to assemble and decide things. Luke proves the point without meaning to: during the riot at Ephesus he uses the word three times of a pagan mob and a lawful civic assembly, in the same chapter where he uses it of Christians.
So the word does not mean a building, and it does not mean a service. It means the people, summoned.
“Meanwhile the assembly was in turmoil. Some were shouting one thing and some another, and most of them did not even know why they were there.”
Acts 19:32 — the confused assembly→
“But if you are seeking anything beyond this, it must be settled in a legal assembly.”
Acts 19:39 — a lawful assembly→
“And I tell you that you are Peter, and on this rock I will build My church, and the gates of Hades will not prevail against it.”
Matthew 16:18→
