What's the right reaction when a white stranger walks into a black church?

The Rev. James Coleman still wonders about the white man who came to church.The unfamiliar face showed up one Sunday at All Nations Baptist Church on Washington's North Capitol Street, a once-working-class neighborhood fast filling up with new condos. The stranger walked into the early morning Sunday school class and stayed all through the service -- but he kept to himself and never said a word. Finally, the pastor asked the man what brought him there that day.
