I have no problem with anybody who wants to bear public witness to their religion, but I don't think they can do it on public property. They have to do it on private property. There's nothing unconstitutional about that.

Our problem is not that we're fallen; our problem is we haven't become human yet. The question is, what can make us human, so that we can give life away and give love away and not be grasping after trying to protect our own lives all the time? That's the way I see the Jesus story, and I think it's a powerful and profound story.

I want to see Christianity enhance our humanity instead of rescue us from some fall. I don't want us to be depending on this supernatural God up in the sky; I want us to recognize that God is part of who we are and that we have to live out the meaning of God with other people. That means we must live in mutual respect and interdependence; it means we have to limit our own desires in order for the body politic to survive.

In my book, The Sins of Scripture, I traced the development of tribal religion, which included ideas like God's killing the Egyptians because they hated the chosen people. Then a God of love finally appears in the Book of Hosea, about the 8th century. A God of justice appears in the Book of Amos in the late 8th century or early 7th century.

I think we have to recover our spiritual nature. The way we have interpreted Christianity does not do that.

The trouble is, the same thing that enabled us to survive evolution is also going to kill us, because in the final analysis, if survival is the primary motivation of every human being, then we will finally be in a situation where might will make right and only one person will survive.

It's just not easy enough to say that I pray and God will accomplish.
