Not really. Confucianism is ingrained into Chinese society in ways the West can't comprehend. UU is a 19th century offshoot of NE Congregationalism.
Oh, I agree. I guess I'm riffing off of superficial similarities. I think some of the Founding Fathers would have tried to create an American civic religion akin to UU, however. (Not necessarily as a conscious decision, but they would have been more comfortable with such a creed in comparison to Puritanism or the sort of revivalism that led to the various Great Awakenings.)
What kind of rituals does the UU have?
From the perspective of a former Epsicopal turning Roman Catholic .. they don't have _any_.
