I know nothing about them. Sorry to hear their members do not know either. Is it kinda like the pcusa in terms of going bad?
United Church of Christ is a different monster. Church of Christ is not so bad.
UCC is very much like PCUSA only they are leading the way out in front. They’ve been heading down the liberal road for a long time.
My mom visited one once and in the sunday school they said believing in the Trinity was optional, that it really didn’t matter.
