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.

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.

You find the most in not any particular denomination specifically. It's the style of worship. So if we have what we call a charismatic worship style, that means upbeat music and a more lively style of preaching usually, people are allowed to clap, say "Amen," whether they're mainline Protestant, conservative Protestant, and Catholics, whatever, they're much more likely to be integrated.

Absolutely, although every congregation will say, you know, every worship leader will say it's vital. It's very important, but again these are, you know, these are different cultural styles.

Scripture is vast, and people can pick and choose what they emphasize, and so for hundreds of years verses that said that you are to welcome the stranger, that with Christ there's neither Jew nor Greek, male nor female, we've broken down the dividing wall with the original church, where Christians were first called Christian was the church of Antioch in which for the first time you had Jews, Gentiles of all different ethnicities come together as one people. That's when they were called Christians.

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.
