Actually, Unitarian is a very ambiguous term. There are the Unitarian Universalists, who now probly dont believe much of anything about the godhead, or even agree if God is in it or if it is just an amalgam of myths, philosophies and avatars.
Then there are the “Biblical Unitarians” who deal with the issue in their own made up(not saying bad, but like Trinity, made up terms) of “God, very God or not God, very God” when is comes to the deity of Christ. This knocks them outside the minimum soterioly requirements of most mainline denominations- altho for the most part they do not include their view on the Godhead as soteriology, and are in most other theological departments just like a bunch of nice Baptist or even Presbyterian brothers.
I have always been intensely interested in the whole Deity thing because it is mysterious and an exciting subject to examine having many nuances and potential perspectives based on the scriptures. The fact that Michael Servetus was burned at the stake for his views really blew my mind, because I have always been the type of person to just look at all the possibilities without getting my ego so attached that i am going to crumble or explode if I am proven wrong or get taken outside my paradigm- I just dig the exploration and I dont think God cares a lick if I am a Trinitarian or a Biblical Unitarian. There is something about Modalism that really bothers me, not the least of which is the aggressive form of sectarianism most of them have about their view, altho I must say many Trinitarians are the same(sectarian). I love Jesus. He is my Lord. YHWH is my Father. Neither of them is threatened by my exploration of the subject, and I rather like that I have never fully settled the issue, boxed it, wrapped it, tagged it in my mind. To me it is a mystery seen through a glass darkly. Maybe that will be wrapped up like a little gift to me some day when, according to the hymn, “we’ll understand it better by and by”
