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.

Call-and-response style, yes, exactly. So whenever different groups get together then there has to be this long period of negotiation. How will we worship? What's acceptable? What's not? If I want to say "Amen" can I?

What's happening is that Asian and Latino and other groups without that history are more likely to end up in either black churches or white churches and then make them multiracial churches. I talk about that in the US we have two cultures.

It happens a little bit more in the West, where there's more fluid - where everybody's originally from somewhere else. So they have a little bit more permission to do it. It happens the least, at the individual level at least, in the South, because the South has very strong, you know, set up black churches and white churches and a long history of that, and so it's a bigger social cost.

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.

Preaching styles and people being slain in the spirit and things like that. Now it doesn't happen in all black churches, and it happens sometimes in white churches, right? But on average they're quite a bit different.

I think it's easier, I really do, because of not having that similar history, so that's why I think two-thirds of these mixed congregations are either white with Asian and Hispanic, or black with Asian and Hispanic.
