An affiliated church MUST have the words "United Pentecostal Church" somewhere on the sign... I do not believe there are any other stipulations/requirements when it comes to naming. I assume that the name would need to be removed if the church was disaffiliated... and obviously the church must be disaffiliated before the pastor could drop his creds so that he doesn't lose the church (or at least the building)... might be funny if the UPC tried to force the issue on someone and they said, Fine, here's the empty building, the keys and the mortgage coupon booklet, the people have decided to come with me. lol.
