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.

It's the sad fact of how race still works in our country. We find that over and over again.

What sort of difficulties would happen when people of different cultures try to come together to worship? Tiny little things such as let's tell jokes with each other.

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.
