Yes, I am pretty sure the Unitarian Universalist Church attempts to affirm most anyone's beliefs. I would not really consider them a Christian church, because their opinion goes something like this: "Some of us believe in Jesus, some of us don't." That's a belief, I guess, but that doesn't really fall into the realms of what "Christians" believe. We used to have a UU minister that lived behind us, and she pretty much told us that this is what the UU church goes by.
Also... I have a friend who used to attend a UU Church in Philadelphia... she didn't really like it because almost every single week they made a huge deal over gay rights and gay marriage. She wasn't against gay marriage... but she got sick of that issue already. It wasn't really what she was looking for in a church. I don't think it's wrong for churches to be politically active, necessarily, but according to her, this was emphasized way too much. They would hang big signs on the church that would say stuff like "Loving Marriage Unions for All" and stuff, and I think that's not what she was looking for in a church.
If you're looking for a church that's less ritualistic... a lot of non-denominational churches aren't ritualistic at all. Many Protestant ones aren't ritualistic, actually. I think Lutherans and some Presbyterians are... but there are a lot of contemporary, non-denominational churches that aren't ritualistic at all.
