"A Chosen Faith" (co-written w/ The Rev. John Buehrens) is an eloquent and concise explication of Unitarian Universalism. "The American Creed" is an equally eloquent explication of the Declaration of Independence and how our understanding of it has evolved and grown. I haven't yet read "Love and Death," but want to. And I look forward to the release in November of Church's final book, "The Cathedral of the World."
Sometime back I heard him interviewed on a podcast of the Diane Rehm show. Search it out. One comment of his I recall is his reply to someone who declares himself an atheist:
"Tell me about the God you don't believe in. Chances are, I don't believe in that God either".
Forrest Church may not have been the first person to say that, but he's the first person from whom I heard that.
Take a look as well at Jess's Journal.
