Paula Fredriksen, Sin: The Early History of An Idea

This week on Religion For Life we get the down and dirty on sin.   Where did this idea come and from and why and how did it develop?  Dr. Paula Fredriksen, The Aurelia Professor of Scripture Emerita at Boston University, is my guest.  She talks about her new book, Sin:  The Early History of An Idea and traces the development of this idea from Jesus to Augustine.
