Is there a religion that does not believe in the holy trinity other than Jehova Witness?
I think the only religion that does the trinity thing is christianity. I have a couple ideas to help you find a religion/church. The Unitarian Universalists are very open and diverse communities that recognize that everyone is on a different spiritual path. They choose to walk together. The UU website is www.uua.org. That can give you more information and help you find a local congregation. My second idea is sort of a cop-out, but have you tried the “What’s Your Religion” quiz on Beliefnet.com? They will ask you a series of questions, then give you results at the end showing what religions your beliefs line up with most closely.
