Who are we?

Dan of Poser or Prophet referenced the discussion on this site about his writing and referred to engaging with “a couple of Evangelical fellows” in debate. Now I suppose he could be referring to some of people in the comments section, but he could also be referring to the authors of this site.

Now, in denominational terms, we’re a fairly heterogeneous bunch (Presbyterian, Anglican, Baptist, just off the top of my head). But what is an evangelical now anyway? Is it about belonging to one of several specific denominations? Is it about certain theological beliefs?
