Adams and Ralph Waldo Emerson among others. It is a well established religion and probably the furtherest thing from a cult that anyone could imagine. There are less established religions with similar names. Some people might call some of them cults. I am a Unitarian-Universalist.
Below are some definitions of a cult. Usually, in my view, members of a cult agree on certain core beliefs that they adhere to almost fanatically. Unitarian-Universalists believe a variety of different things. The one thing you can be sure of is that we don't all believe or think alike. I remember that at a meeting of Sunday School teachers, our assistant pastor asked how many of us believe that there is a life after death. About 40% of the teachers raised their hands. On almost any issue, you will find that Unitarian-Universalists, unlike members of a cult, have distinct opinions and beliefs. We have a few things in common -- we like to discuss -- we generally don't like dogma -- we enjoy the quiet of Sunday services, thoughtful sermons, good music, or any one of these things. The first Unitarian church that I attended way back in the 1960s didn't have sermons. We just sang Bach chorales. Finally there was a minister. I was very young at the time. It seemed to me that he just appeared out of nowhere. Maybe I had simply been going to the wrong services. I will never know, but I had a great experience and have been a Unitarian ever since. I think a lot of DUers would like Unitarian-Universalism.
