In part because they had no choice, right? If you were a slave, you did what the master said. And they said to worship: "You're going to worship with us."

So we didn't get the denominations and the separate congregations really till about into Civil War time. What's happened then, of course, is now that we've had well over 100 years of this history to establish separate cultures, different ways of worshipping, and different ways of understanding theology so that when people try to come together makes it very difficult. And then, of course, social networks, you know, how do we find a place to worship?

And then they would have the shoe removers on one side, and the non-shoe removers on the other side until they could work through coming to understand why we might both be trying to worship authentically, and because of our cultural background we have these different ideas. But it took a while.

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.

Humor is so culturally based that when I try to tell a joke as me being a white American, if I tell other white Americans, they'll laugh. If I tell an African American, they might not laugh. In fact, they either might not find it funny, or they might find it offensive, and I didn't mean it to be offensive. So these are the sort of little things that build up over time, just like in a marriage. You know, the little things can build up over time.

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.
