BRTD, what is your denomination again...? Lol.
Non-denominational.
No other categorization? For example, some people I knew in Iowa City who went to this church called Parkview were technically "non-denominational" or whatever (and that is certainly how they described themselves), but their website says they are part of the Evangelical Free Church.
My former church was completely non-denominational (and thus had to be entirely self-sufficient financially, which ended being a problem), and I haven't joined a new one since it, our last gathering was just a month ago. It started as a branch off from a Presbyterian one and met at a Congregational church but had no affiliation with those denominations.
