Acts 19:32

We should probably understand Luke’s reference to the confusion of the crowd as pertaining to the exact grievance of the silversmiths. Most of the people did not understand the reason for the gathering; they just went along for the excitement. The Greek word translated "assembly" (cf. Acts 19:39; Acts 19:41) is ekklesia, the normal translation of which is "church." This use illustrates the basic meaning of the word, which is an assembly of people called out of the mass for a special purpose.
