Unitarianism is the belief that God exists in one person, not three. It is a denial of the doctrine of the Trinity as well as the full divinity of Jesus. Therefore, it is not Christian.
That's from CHRISTIAN APOLOGETICS & RESEARCH MINISTRY
I think my background is just too steeped in the Christian tradition to deny the divinity of Jesus or the Trinity.
Well, any other suggestions?! I've often thought of researching some of the Eastern traditions. Some of them seem to be more life philosophies than religions; things that could comfortably sit alongside my "God doesn't care but I still feel the need to be a good person" sort of thinking. I figure I have to come up with a sound religious philosophy before the Little Miss is old enough to start asking piercing questions.
