[Evangelical]

I think you're confusing denominational names with necessary names or descriptions. "The prayer meeting at Sister Smith's house" and "the home meeting at Brother Bob's" is the same practice of the local churches, and these are not considered to be "names" but descriptions. The issue arises when the "at such and such a place" or "Christians in the place" becomes "Christians of the place".

To be denominated (i.e. de-name-iated) Sister Smiths house would have to lead to a denomination called Smithonianism and Brother Bob's house becomes Bobianism and the Bobanites. There was a man named Fred. He grew up in a Bobian family, and he is Bobian from birth (he was baptized as a Bobanite), and his parents hope he will continue in the Bobian traditions. And there we have the denominational situation.
