Scholar's church closes its doors

First Baptist Church of Mt. Vernon, Illinois, has held the last service of its 156-year history. It's among many U.S. churches that close their doors each year. But there's a poignant twist in this story. First Baptist's pastor, Ryan Burge, spends much of his time as a researcher, documenting the dramatic decline in religious affiliation in recent decades. With more Americans abandoning religious affiliation, it's hard to grow and sustain a church, Burge says. He hopes his research, and his personal experience, can provide comfort to other pastors of struggling churches. "This is not all your fault," Burge tells them.
