Garry Wills on the Bond Between Religion, Morality, and Politics

In a new book about the constitutional separation of church and state, Pulitzer Prize-winning historian Garry Wills insists that that separation was meant as "the great protector of religion, not its enemy." That, as Wills tells guest host Dave Davies, hasn't stopped fervent believers from challenging the concept.

Wills, a translator of St. Augustine and author of What Jesus Meant, is an emeritus professor of history at Northwestern University; the new book is titled Head and Heart: American Christianities.

It’s called “Papal Sin: Structures of Deceit.” (Doubleday) Wills is a practicing Catholic and studied with Jesuit priests, though he was never ordained.
