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 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.

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.

Every Christian in every time and place is going to be tempted by certain forms of heresy. I'm sure I'm tempted by my own.

It's just silly to look at the incredibly steep decline in the mainline and the clear institutional weakening of Catholicism in the 1960s and 70s and pretend that something really big didn't change then. It did change. There really was a significant institutional decline.

If you're willing to recognize the religious element in one secular ideology, you need to be able to recognize it in your own.
