This is increasingly the face of religion in America  fluid, fluctuant, questioning, nonconformist and in many cases unaffiliated.

That’s why a report this week by the Pew Forum on Religion and Public Life about the religious composition of the 112th Congress caught my eye. According to the report, the unaffiliated (atheists, agnostics, the unchurched, uncommitted, etc.), at 16.1 percent of the population, is the largest religious group in America without representation in Congress. (Six members, about 1 percent, did not specify a religious category.)

For perspective, there are almost two-thirds as many unaffiliated people as there are Catholics in this country and nearly as many as there are Baptists. Their number is more than twice that of Methodists, and more than nine times the numbers of Jews or Mormons. Yet, no unaffiliated representation. Why?

First, let me get this out of the way: I don’t for a second believe that all those members are religious. I believe some are trapped in the religious closet of American politics where nonbelief is a nonstarter. It’s not only seen as unholy, it’s also seen as un-American. (Although Pete Stark, a California Democrat and a Unitarian, has said that he doesn’t believe in a Supreme Being. One out!)
