When you walk into Trinity United Church of Christ on the South Side of Chicago, the first thing you see on a Sunday morning are the people crowding the lobby, hugging and kissing, asking after each other’s children. The congregation is older and formally dressed. Many of the women wear fur coats, stockings and heels; almost no one is dressed in jeans. As an usher leads a reporter upstairs to the pastor’s office, he rebukes a young boy: “Take off your hat in church, son.”
