Penn professor JOHN DiIULIO has long been an advocate for the role of faith-based organizations in the delivery of social services provided by the government. Over the years, in the Philadelphia area, he has created programs to mentor the children of prisoners, promote literacy in low-income communities, reduce homicides in high-crime police districts and save inner-city Catholic schools that serve low-income children. In 2001, he served as first director of the White House Office of Faith-Based and Community Initiatives in the Bush Administration and left the post later that year frustrated by politics. In late 2008 and early 2009, DiIulio consulted with the transition team of President Barack Obama regarding the restructuring of the White House faith-based initiative. He joins us for a conversation in the studio about the role of religious organizations in public life and the intersection of politics, government and religion.
