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.

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 fair, in a way, to describe certain forms of Marxism, for instance, as the secular equivalent of a religion. But, I think the same is true, to a certain extent, of secular liberalism as well.

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

The idea of universal human rights may not seem as weird to some people as the idea of a personal God, but it is still a metaphysical idea that liberalism, at least as we know it, couldn't really survive without.

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.

Even secular people can't really escape from the need to rest their ideas on some belief, some sort of commitment that is not scientific commitment.
