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.

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 Democratic Party's rigidly pro-choice stance is one of the more unyielding positions in contemporary American politics.

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.”

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.

I do think that evangelicals in general need to think seriously about how you pass on your faith across generations and over the long haul.

One of the things I try to do is take seriously some of the forms of American religion that people consider to be shallow and try and figure out why they have such a strong appeal and tease out the theology they actually represent.
