I first met TM when he was an assistant pastor at Coral Ridge Presbyterian Church back in the late ‘70s. He was a close friend of a close friend who was also an assistant at CRPC. He went on to serve for a time at Chesapeake Seminary (now Chesapeake Reformed Theological Seminary), but he no longer serves that institution. I believe he is still associated with Prison Fellowship and now hosts something called
The Fellowship of Ailbe, "a spiritual fellowship in the Celtic Christian tradition".
His writing is very good, IMO.
