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.

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.

In the end, you do need institutions to transmit the faith for the long haul. That's why I make the case that, in certain ways, American Protestants could stand to recover the denominationalism that they've left behind over the last 50 years. They are real values in having a confessional tradition that can sustain your faith over the long term.

The idea of a post-religious society is a fantasy, ultimately. Human beings are, by nature, religious in various ways.

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.

During a frustrating argument with a Roman Catholic cardinal, Napoleon Bonaparte supposedly burst out: “Your eminence, are you not aware that I have the power to destroy the Catholic Church?” The cardinal, the anecdote goes, responded ruefully: “Your majesty, we, the Catholic clergy, have done our best to destroy the church for the last 1,800 years. We have not succeeded, and neither will you.”
