One of the things we find when we talk to people that attend these congregations, they all have social cost to it. People want to know why they're doing that. Sometimes they're questions about selling out on their race or "Are we not good enough that you have to go to this kind of congregation and not ours?" So there are costs to it, and I think they're a little bit higher in the South because of its history.

I ask the clergy why don't I see myself represented in leadership? And I'm told, and this happens quite a bit, "We don't think about race when we hire. We just hire the best person for the job."

So the tradition from Europe is that you're supposed to emphasize the mind over the body, so you sing from a very kind of staid perspective. Again, there are charismatic white congregations all over, and they don't sing that way. But, you know, on the average.

I think with President Obama there's going to be a discussion, because he himself is multiracial, because we have for the first time a non-white president. There's going to be talk about what does this mean? What is it? Are we in a new era?

So one of the profound things we found when studying these congregations, the mixed ones, is just how much overlap and interracial ties that develop not only with the people in the congregation, but they start meeting each other's families, and their friends, and they go to each other's neighborhoods if they live in different neighborhoods, and at work they meet people they wouldn't otherwise met, and so it creates a whole new definition of what the group is.

They could never go back to being a uniracial congregation again. It brings excitement. It brings life. It allows them to be able to know people they would never know, to meet people that are outside the congregation they would have never connected with, you know, through the networks that they developed in the congregation.

Every pastor I talk to says, and particularly if they're African American they'll say, "I'm not black enough for African Americans. I'm not white enough for the whites. I'm not Hispanic enough."
