This verse satisfies your unnecessary requirements:

Act 13:44 The next Sabbath nearly the whole city assembled to hear the word of the Lord.

I'm afraid that dog won't hunt. Apparently what you think it say is this :

Act 13:44 The next Sabbath the whole church assembled to hear the word of the Lord.

But it does not say that. Unless you belive that nearly the whole city is another way to denote baptized Christians.

If was a first century evangelistic crusade. If Billy Graham were a Calvinist, we would say it was a Billy Graham crusade.

It was not a church gathering per se.

But thanks for playing.
