I really enjoy going back through the UU history for this kind of discussion...it seems so many great ideas have been left behind. Sometimes I call myself a "Trinitarian Universalist", since the idea of three different aspects of God in one does carry somemeaning for me. But the "Unitarian" aspect appeals because it symbolizes a rebellion against ideas that claim absolute authority from the slimmest of Biblical citations.
There's another background to the word "Unitarian", though, claiming that it's not really anti-Trinitarian (except by historical accident):
"[FONT=Verdana, Arial, Helvetica, sans-serif]It is interesting to remember that the name "Unitarian" was once given to a number of religious bodies which had pledged themselves not to persecute one another. This was in the sixteenth century, in Transylvania, and the meaning intended by the name was that of unity. Those who had made the pledge of mutual toleration had to that extent banded themselves together and were known as the "United" or the "Unite-arians." It was soon discovered, however, that some of those within this league were rejecting the dogma that God is a trinity, and so the believers in this dogma, who began to be called the "Trinitarians,", withdrew at once, leaving to the remainder the name "United" or "Un."
