The July 2011 edition of the Journal of American History includes David Hollinger’s article, based on his Presidential Address, “After Cloven Tongues of Fire: Ecumenical Protestantism and the Modern American Encounter with Diversity.” In it, Hollinger describes the social thought of those mid-century Protestants, whom he calls “ecumenical Protestants,” who quit thinking in particularistic Christian and American terms and instead began to recognize that “the diversity of the human species and the diminution of inequalities within it were intimately bound up with one another.” Seeking justice between peoples became a more important calling than seeking to convert non-Christians.

Hollinger’s essay claims to make two important contributions. First, he argues that a better understanding of mid-century ecumenical Protestant thought helps us come to terms with “the dialectical process by which ecumenical Protestants lost their numbers and their influence in public affairs while evangelical Protestants increased theirs.” More: “Politically and theologically conservative evangelicals flourished while continuing to espouse popular ideas about the nation and the world” — such that the United States was an exceptional nation because it was founded as a Christian nation — ideas “that were criticized and abandoned by liberalizing, diversity-accepting ecumenists.” Ecumenical leaders did not speak for their congregants. In this, Hollinger adds complexity to accounts of secularization that focus on non-religious free thinkers, such as David Sehat’s The Myth of American Religious Freedom. Not enough intellectual historians focus on what my friend Bo Peery calls the Christian Left, except perhaps to take note of Niebuhrian realism. So I find this claim uncontroversial.

Hollinger’s second claim is more provocative. He contends that ecumenical Protestants might have lost their grip on Protestant America, but they helped pave the way for a more diverse multicultural America. In making this argument he draws a compelling analogy. I quote Hollinger’s penultimate paragraph in its entirety to give you a flavor:
