USA Today forum: Are mainline faiths dying?

Earlier this month, Diana hosted a forum at USAToday.com, called "Are mainline faiths dying?"

Statistically, the mainline has declined by the millions in recent decades. But church historian Diana Butler Bass makes a contrary case: That it is thriving despite the odds. She once told me, "Mainline congregations have a beautiful world where they are enacting service, doing justice, learning to pray and caring for one another. And no one seems to realize they are there."
