The idea of bringing people of different faiths together to pray to Deity, both monotheists and polytheists, I think is a good one. Very Bahaiesque. Could we have a purpose for the prayer that would bring us together? Like a prayer for peace. Peace is something that Christians, Jews, Muslims, Pagans, Buddhists, UU, and other could agree on. I also think a UU church idea is a good one. It is avenue that a lot of people of faith, who lean a tad in the progressive direction, would feel comfortable about. Let me know what I can do to help. It is a good idea.
