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 what you see a lot of in American religion, even in areas of American Christianity that don't go all the way with Osteen to the idea that God wants you to have this big house and so on, the nature of American religion right now, the fact that it is so non-denominational and post-denominational, the most successful churches have to be run more like businesses than ever before. I think that just exposes Christians to a constant temptation to think about the ministry more as a business than they sometimes should.

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.

It's not always clear where a healthy patriotism shades into a dangerous nationalism.

I think it is very clear that, though great difference remained, evangelicals moved closer to Catholics, mainline Protestants and evangelical Protestants moved closer together, and this convergence coincided with greater institutional strength for all the Christian churches than, for the most part, you see today.

In many ways, American evangelicalism is somewhat stronger today than it was in, say 1955 - certainly more mainstream and influential in the culture as a whole. But, the increased strength of evangelicalism hasn't increased fast enough to compensate for the total collapse of mainline Protestantism and the pretty steady weakening of my own Roman Catholic Church.

My mother converted when I was 16. She was the driving force behind religion in our family. So, I'm sure I was heavily influenced by that. But, I also was, and still am, convinced by the Catholic churches historical claims to represent the continuity with the early Church that other forms of Western Christianity lack.
