Finally, any reconciliation between faith and democratic pluralism requires some sense of proportion.

This goes for both sides.

Even those who claim the Bible's inerrancy make distinctions between Scriptural edicts, sensing that some passages - the Ten Commandments, say, or a belief in Christ's divinity - are central to Christian faith, while others are more culturally specific and may be modified to accommodate modern life.

The American people intuitively understand this, which is why the majority of Catholics practice birth control and some of those opposed to gay marriage nevertheless are opposed to a Constitutional amendment to ban it. Religious leadership need not accept such wisdom in counseling their flocks, but they should recognize this wisdom in their politics.

But a sense of proportion should also guide those who police the boundaries between church and state. Not every mention of God in public is a breach to the wall of separation - context matters. It is doubtful that children reciting the Pledge of Allegiance feel oppressed or brainwashed as a consequence of muttering the phrase "under God." I didn't. Having voluntary student prayer groups use school property to meet should not be a threat, any more than its use by the High School Republicans should threaten Democrats. And one can envision certain faith-based programs - targeting ex-offenders or substance abusers - that offer a uniquely powerful way of solving problems.

So we all have some work to do here. But I am hopeful that we can bridge the gaps that exist and overcome the prejudices each of us bring to this debate. And I have faith that millions of believing Americans want that to happen. No matter how religious they may or may not be, people are tired of seeing faith used as a tool of attack. They don't want faith used to belittle or to divide. They're tired of hearing folks deliver more screed than sermon. Because in the end, that's not how they think about faith in their own lives.

So let me end with just one other interaction I had during my campaign. A few days after I won the Democratic nomination in my U.S. Senate race, I received an email from a doctor at the University of Chicago Medical School that said the following:

"Congratulations on your overwhelming and inspiring primary win. I was happy to vote for you, and I will tell you that I am seriously considering voting for you in the general election. I write to express my concerns that may, in the end, prevent me from supporting you." The doctor described himself as a Christian who understood his commitments to be "totalizing." His faith led him to a strong opposition to abortion and gay marriage, although he said that his faith also led him to question the idolatry of the free market and quick resort to militarism that seemed to characterize much of the Republican agenda.

But the reason the doctor was considering not voting for me was not simply my position on abortion. Rather, he had read an entry that my campaign had posted on my Web site, which suggested that I would fight "right-wing ideologues who want to take away a woman's right to choose." The doctor went on to write:

"I sense that you have a strong sense of justice...and I also sense that you are a fair minded person with a high regard for reason...Whatever your convictions, if you truly believe that those who oppose abortion are all ideologues driven by perverse desires to inflict suffering on women, then you, in my judgment, are not fair-minded....You know that we enter times that are fraught with possibilities for good and for harm, times when we are struggling to make sense of a common polity in the context of plurality, when we are unsure of what grounds we have for making any claims that involve others...I do not ask at this point that you oppose abortion, only that you speak about this issue in fair-minded words."
