And again, this connection that you get: I meet Joe at church. Joe's connected to a whole network of people I don't know. Joe likes me. He invites me over to his son's birthday party, and I meet his whole family. I meet his friends. I get to know his neighborhood. That happens all the time.

To a large extent, people's interest in the character is the mystery of the character.

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.

That's a big fear, right, and when I talk with black pastors, the same thing: If we try to have this move towards interracial congregations, whites will just dominate then. There are so many more of them, and they're used to being in the position of power. So they'll just take over, and we'll lose the one thing we do have.

I think it's going to open up a wider place for a discussion about we ought to come together in our churches, in our neighborhoods, in our work places, in our clubs and our networks. I think it'll be more acceptable to talk about it. We'll see what happens. It'll take some time. But I think it will.

So different groups have different definitions, and then they clash on those. So it takes adept leadership to say we're going to work through these.

We just say there are five, you know, racial groups in the US. I say that these folks are what we call a sixth American. There's something different. They are somebody who - they don't exist in any particular racial category, so they all feel it and they kind of congregate to each other.
