Americans are an "almost chosen people," which is meant to suggest that there are clear parallels, literal, theological and everything else, between the American story and the Old Testament story of Israel and then the broader story of the Christian church. It's OK to recognize the parallels. It's OK to invoke them. But, you have to keep that "almost" in front of the "chosen." You can't go all the way and say, "America is Israel, America is the Church." That's where I think patriotism shades into, what I call, the heresy of nationalism.

I think that secular liberals need to recognize that they are still, often, hanging their worldview on what are metaphysical ideas.

It's clearly the case that there's not some moment in American history when every evangelical is holding hands with every Catholic who is holding hands with every mainline Methodist, or what have you. Obviously, American Christianity was deeply divided in all kinds of ways at mid-century too. But there was a kind of convergence going on. Even though Reinhold Niebuhr, the great mainline Protestant theologian, didn't think highly of Billy Graham, he and Graham still, clearly, had more in common, both theologically and in their attitudes toward religion in public life.

Just as the superstar pastor model can have its problems once the superstar pastor gets old or has a scandal or something, the house church model... there's a reason that the house churches of the New Testament era grew up into a more institutional faith down the road.

Independent of the critique I'm making, I'm just trying to paint a more comprehensive portrait of American religion than you get from a right versus left, religious conservatives versus secular liberal, believer versus atheist, binary. Too often, we just look at religion in America through that kind of either/or lens. I think it's much more complicated than that.

What replaces Christianity isn't going to be Richard Dawkins, Christopher Hitchens, and so on. It's going to be something else and something secular people may not like very much.

Many things about American life, that even secular people consider good, have flowed from the presence of a robust, resilient institutional Christianity.
