There's still plenty of people who have this deep conviction that America is a Christian country and ought to say so in its Constitution, etc. But that's not the legal basis on which we're framed. So the flourishing of religion, of religious diversity, is really built into who we are.

My first intellectual challenge was to try to understand this incredible city of Banaras (also called Varanasi) in India and its meaning for Hindus. That was the place I lived for the first year I was in India and I've been back many times. It's a kind of home to me.

People came as immigrants from all over the world, and Hindu and Muslim and Buddhist and Sikh communities became part of the landscape of the U.S.

That is the strength of having a trusting and ongoing relationship that draws on our history and moves right on into our present, and I have that kind of marriage.

When immigrants come, the freedom to practice their faith is a guarantee. They may have trouble with their neighbors, but freedom of religion is part of the blueprint for America, and that is the recipe for the religious diversity that we have today.

People get tired of talking about American exceptionalism, but I think this is an extraordinary thing about the United States, that we are a nation of immigrants, first of all, that is built upon a pluralistic society of native people that were here to begin with. The issue of diversity is really with us from the beginning.

I was a young woman who had grown up in the mountains of Montana as a Protestant Methodist in a pretty good social gospel tradition. I became fascinated with the religious lives of others who seemed also to be very religious, yet in ways that were quite different from my own. That fascination led to relationships, in India and elsewhere, with families of Hindus, of Muslims, of Sikhs, and a lot of study.
