I meet almost no one that goes to an African-American church or thinks, "I'm going to do that." Now there are whites in African-American churches. They're interracially married. They're highly committed. Maybe there's a professor or two, or a student.

Maybe there's even anger. But if they make it through that they come to a new agreement, and they start creating a new culture, and it becomes something that people just - a lot of times they'll say, "I couldn't live without it. I just have to be there."

There are three things, and it depends on the group that we're talking about, but there's history, there's culture, and then there's social networks. So, you know, historically black and white, they worship together until about the end of slavery, and people started moving out into separate churches. But it was because of discrimination and racism and such that blacks began to establish their own denominations and their own churches.

I see it happen in uniracial congregations all the time. But people - when they're in mixed company, we speak differently.

I have to conclude, oh, the best people are all somebody other than my own race. So that's difficult. How do we interpret the Bible? Should we stress things like justice and that God is somebody who cares about equality of all people? Or is he a God of love and a God who's there to give me an afterlife?

We've had people say, "Now when I go to work, I don't feel uncomfortable talking to people of different races, and I go up and introduce myself, and I start making a new friend I wouldn't have done otherwise."

I think it's pretty dynamic. There's a lot of energy there and life, and you'll have women dressed in their traditional African dress when they come, and you have people from all over the place, and some people have headphones on because they're listening in Spanish.
