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.

There's one denomination in particular, though, that has pushed very hard to be multiracial in its denomination - not only its denomination but, I mean, in its congregations, and it's called the Evangelical Covenant Church, http://www.covchurch.org/ which is headquartered in Chicago. Their whole goal is that's the kind of churches they start, multiracial, and I think they say now 20 percent of their churches are that.

I never meet a church that wishes they didn't do it. I never meet a leader that wishes they didn't do it. They will all say, to the person, it's hard. It's difficult. It comes with complexities and confusion as you're trying to go across cultures, and you don't understand, you didn't mean to offend somebody but you've offended somebody. But they will all say it just does something.

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.

There's always the question of time. Does time at 10:00 mean 10:00 sharp? Or does it mean give or take a few minutes? And a few minutes, is that plus or minus two minutes? Or plus or minus ten, or maybe a half an hour each way?

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 spent a lot of time developing in books why worshipping separately actually impacts inequality, economic, social, on and on. So I really do believe there are huge advantages to being together even though it's difficult, even though we have a lot to learn.
