You start reading C.S. Lewis, then you’re reading G.K. Chesterton, then you’re a Catholic.

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.

No one doubts that pure libertarianism is simple, but that's just why it remains on the ideological fringe - because it boils down the most difficult questions in human affairs to a simple equation, a What Would the Market Do bumper sticker.

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.

The fact that institutional churches have gone into decline doesn't mean that we're going to enter some purely secular age. Secular people need to be aware of that.

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 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.
