I believe history will come to view 9/11 as an event on par with November 22,1963, the date on which John F. Kennedy was murdered, cutting short a presidency that was growing ever more promising. Dreams died that day in Dallas it is easy to imagine the 1960s turning out rather differently had President Kennedy lived.

Religious belief, like history itself, is a story that is always unfolding, always subject to inquiry and ripe for questioning. For without doubt there is no faith.

History tells us that America does best when the private sector is energetic and entrepreneurial and the government is attentive and engaged. Who among us, really, would, looking back, wish to edit out either sphere at the entire expense of the other?

The past always seems somehow more golden, more serious, than the present. We tend to forget the partisanship of yesteryear, preferring to re-imagine our history as a sure and steady march toward greatness.

The problem for those who assert biblical authority in support of traditional definitions of marriage is that one could, with equal validity, assert that the lending of money or certain kinds of haircuts are forbidden by God, or that slavery and the subjugation of women are authorized by the Lord.

If a person is homosexual by nature - that is, if one's sexuality is as intrinsic a part of one's identity as gender or skin color - then society can no more deny a gay person access to the secular rights and religious sacraments because of his homosexuality than it can reinstate Jim Crow.

A wise nation should cultivate a political spirit that allows opponents to cooperate without fearing an automatic execution from their core supporters. Who knew that the real rogues in American politics would be the ones who dare to get along?

It would be great if politics were fact-based, but it is not, and it is surely not nuance-based. What works in a classroom or a think tank does not work on Capitol Hill or in the White House. Obama sometimes seems to be running the Brookings Institution, not the country.

While we remain a nation decisively shaped by religious faith, our politics and our culture are, in the main, less influenced by movements and arguments of an explicitly Christian character than they were even five years ago. I think this is a good thing - good for our political culture.
