Marcus Borg has been appointed as canon theologian at Trinity Episcopal Cathedral in Portland Oregon. The name of his church is of course deeply ironic in light of his beliefs. He remains a layman, which raised my eyebrows. I understood that canons were priests. Apparently that was an error.
The only other canon theologian of whom I am aware is the Rev. Dr Kendall Harmon of South Carolina. The Rev. Dr. Harmon has been known to blog occasionally, in his spare time.
I would pay good money to witness a live theological smackdown (debate) between the two.
