Let's hope their faith comes through? If there "faith" tells them it's okay to deny essential rights to those who don't share that faith, that's the last thing I want!

I understand your point, but I would put it this way. Let's hope they're good people who respect others and want to treat them justly. If they happen to come by those values by way of religion, great. If they happen to be conscientious atheists who respect the Constitution, that's fine too. 

At the end of the day, I'm more concerned about what they do than why they do it.
