Back in the mid-1990s I wrote a book on sin. Each of us knows sin experientially, of course, but few of us know it comprehensively even in that way because we are parochial even in our sinning. So I had to study sin. For a couple of years I read about sin in the Bible. I read commentaries on the Bible, theological encyclopedia articles and books on virtue and vice.
Several years ago I met in D.C. with a group of young evangelical professionals. While certainly not world-fleeing fundamentalists, they were not theocrats either. They were seeking an alternative approach.
