Diversity within the Church.

Interesting article over on cnn.com about racial and ethnic diversity -- or the lack thereof -- in American churches:

Americans may be poised to nominate a black man to run for president, but it's segregation as usual in U.S. churches, according to the scholars. Only about 5 percent of the nation's churches are racially integrated, and half of them are in the process of becoming all-black or all-white, says Curtiss Paul DeYoung, co-author of "United by Faith," a book that examines interracial churches in the United States.

DeYoung's numbers are backed by other scholars who've done similar research. They say integrated churches are rare because attending one is like tiptoeing through a racial minefield. Just like in society, racial tensions in the church can erupt over everything from sharing power to interracial dating.

DeYoung, who is also an ordained minister, once led an interracial congregation in Minneapolis, Minnesota, that eventually went all-black. He defines an interracial church as one in which at least 20 percent its membership belongs to a racial group other than that church's largest racial group.
