Remember him from law school, he was kind of grouchy in those days (pre-Christian I suspect). He supposedly became a Christian after attending First Presbyterian Church in Berkeley (where I went), and I know he wasn’t going there yet when I was in law school. Before you pooh-pooh Berkeley too much, I was amazed to find when I first went there that there were a ton of Christians in Berkeley, both in the University and outside. And First Pres had some great pastors, including Dr. Munger who wrote the famous tract, “My Heart Christ’s Home.”
In terms of Christian presence, I might note that the faculty adviser to the Christian Legal Society at Boalt while I was a student was the then-dean of Hasting Law School across the bay in San Francisco, an open Christian.
How times have changed (Hastings was the law school which first banned Christian organizations for not being “inclusive”—that decision was upheld by the U.S. Supreme Court and has led to academic persecution of Christians ever since.)
