Beliefnet has an engaging interview with John Edwards and his religious faith here. Money quote:
"It's important to - or at least in my case, to have a personal relationship with the Lord, so that I pray daily and I feel that relationship all the time."
"Allowing time for children [in school] to pray for themselves, to themselves, I think is not only okay, I think it’s a good thing."
"I do believe in the separation of church and state. But, I don't think separation of church and state means you have to be free from your faith."
I believe all three things. I'm happy to hear a Democrat say it. And notice this isn't Christianism. He is speaking of his faith, not his politics. And he understands the importance of putting clear sky between the two.
