'Whole Church' in the Bible

And great fear seized the whole church and everyone else who heard about this.

Then the apostles, the elders, and the whole church decided to choose some of their men to send with Paul and Barnabas to Antioch. These were Judas, who was called Barsabbas, and Silas, who were leaders among the brothers.

Gaius, who is host to me and the whole church, greets you. Erastus, the city treasurer, and our brother Quartus greet you.

Now if the whole church gathers in the same place and everyone is speaking in foreign languages, when uneducated people or unbelievers come in, they will say that you are out of your mind, won't they?
