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.

Institutional Christianity has had clear secular benefits to American life for hundreds of years. It's played both a prophetic role in terms of generating moral critiques of American excesses, and so on, and also a communal role, in terms of building community as the country moved westward to the role my own Catholic Church played in assimilating generations of immigrants.

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.

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

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.
