David Brooks sorts it out on the NYTimes op-ed page

George W. Bush was born into an Episcopal family and raised as a Presbyterian, but he is now a Methodist. Howard Dean was baptized Catholic, and raised as an Episcopalian. He left the church after it opposed a bike trail he was championing, and now he is a Congregationalist, though his kids consider themselves Jewish.

Wesley Clark’s father was Jewish. As a boy he was Methodist, then decided to become a Baptist. In adulthood he converted to Catholicism, but he recently told Beliefnet .com, “I’m a Catholic, but I go to a Presbyterian church.”

What other country on earth would have three national political figures with such peripatetic religious backgrounds? In most of the world, faith-hopping of this sort is simply unheard of. Yet in the United States, we simply take it for granted that people will move through different phases in the course of their personal spiritual journeys, and we always have.
