But in the US, when you have two separate cultures, each with its right, each of which has come to exist in this political entity in the last couple hundred years, each feeling like, "I have the right to hold onto my culture," and that's what makes it difficult.

If we go into white congregations, non-whites will sometimes say it felt like worship never started. It was sort of dead and didn't feel that warmly received. But so - and there are different realities either way, and it makes it difficult for all groups to try and cross boundaries.

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.

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?

There's a lot of life there, but it's a different sort, because there's a lot less immigrants and a lot more racial, the mix of black and white in particular. I've actually never been to their worship for an extended period of time, so I can't comment wisely on it.

Then of course there are bigger things that matter, like who do I see up there in the congregation? Do I see myself up there? Well, I don't.

We're going to see more, and we are seeing more, and I'll tell you exactly why. Not because white and black are more likely to get together. Only a third of the seven percent of congregations that are interracial are black and white.
