If I want to put a Christmas tree in my yard, or three crosses for the crucifixion story, that's fine. But if I try to use public property or a public school as a way to impress my religion on other people, I think that violates the constitution.

In the private arena, you can do whatever you wish, and people do. These crazy evangelical preachers get on the radio and TV and say incredible things.

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.

You can't go to church without praying ten or fifteen times for God to have mercy on you. You can't sing "Amazing Grace" without reminding yourself that the reason God's grace is amazing is it saves a wretch like you. This self-denigration stuff - Jesus died for my sins - is nothing but a guilt message. That's the thing we've got to get out from under. That's not Christianity. That's sort of fourth-century Christianity that got turned into doctrines and dogmas that we've never been able to escape.

I learned early in life that you get places by having the right enemies.

I think I could make the case for any kind of organized religion, but I'm not an expert in those, so let me narrow my focus to talk about Christianity.

Malachi, the last book of the Old Testament, says, "From the rising of the sun to its setting, God's name shall be great among the Gentiles." This encompasses the whole world. Suddenly it's not the Jews against the Gentiles, or my tribe against your tribe.
