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

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.

Our culture has few taboos that can't be violated, and our establishment has largely given up on setting standards in the first place. Except where Islam is concerned. There, the standards are established under threat of violence, and accepted out of a mix of self-preservation and self-loathing. This is what decadence looks like: a frantic coarseness that "bravely" trashes its own values and traditions, and then knuckles under swiftly to totalitarianism and brute force.

I do think you can see, throughout American history, this temptation, and it's both a liberal and a conservative temptation, to take a healthy patriotism a little too far. For liberals the temptation is to say the purpose of politics is to straightforwardly bring the kingdom of God to Earth. For conservatives, I talk about Glenn Beck, the temptation is more apocalyptic and messianic, it's the temptation to say we did have a covenant with God, a literal covenant beginning with the Founding, and we are, like Israel in the Old Testament, falling away from it.

I think that secular liberals need to recognize that they are still, often, hanging their worldview on what are metaphysical ideas.

My mother converted when I was 16. She was the driving force behind religion in our family. So, I'm sure I was heavily influenced by that. But, I also was, and still am, convinced by the Catholic churches historical claims to represent the continuity with the early Church that other forms of Western Christianity lack.

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.
