Actually, not. It started out that way but dropped the Christian stuff after a while. Check it out it's interesting! Unitarian Universalism. (For an introduction : Unitarian Universalism - Wikipedia, the free encyclopedia)

You should like it, Dennis. Given its mission statement, it counts to me as a "responsible religion". In fact, it pretty much addresses all your points (community, etc.), without committing anyone to a specific faith. The basic principles are purely moral ("affirm and promote the dignity of every person") and don't reference a "god" at all, so even atheists are welcome apparently.
