Tom Porter, talking to me about the substance of what you might want to hear, mentioned a series of articles in The Christian Century, by prominent theologians, called “How I Changed My Mind.” I remember especially Karl Barth's three contributions to the series, over a period of thirty years.
Ed Gaffney, years ago, introduced me to Barth—and did it with a perfect reference: to the prison sermons Barth gave when he turned, at least a little bit, from being a theologian and returned to being a pastor. Barth said the jail was his favorite pulpit. “There are but few theology professors,” he said, “whose sermon listener one can become only after having committed a serious violation of the civil order.”
My own changes of mind are not unique. I am one of a small group of law teachers who have, over the last thirty years, become clearer in formulating an Hebraic legal ethic. We are a minority who have become bolder. We owe such courage as we have located for that to modern pioneers, most notably Harold Berman, and, more lately, Emily Hartigan. What has changed most for us has been the clarity of our public witness; the substance all along has been old-time religion. When I say “clarity” I mean that we have come to see this substance in our work, more than we did in, say, 1970.
