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.

Maybe there's even anger. But if they make it through that they come to a new agreement, and they start creating a new culture, and it becomes something that people just - a lot of times they'll say, "I couldn't live without it. I just have to be there."

We studied a mosque, and this is when we were at Notre Dame, and in this mosque they had people from a variety of countries, most of them immigrants. In some of the countries, when you go into a mosque you remove your shoes. To not do so could be punishable even by death in that nation. In other countries, it would be a great offense to remove their shoes when they come into the mosque, a sign of disrespect.

I see it happen in uniracial congregations all the time. But people - when they're in mixed company, we speak differently.

My mother always told me growing up I had a punchable face. Little did I know she was predicting my television career.

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.

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.
