In 1984, Jean Vanier invited me me to visit L'Arche community in Trosly, France. He didn't say "We need a priest" or "We could use you." He said, "Maybe our community can offer you a home." I visited several times, then resigned from Harvard and went to live with the community for a year. I loved it! I didn't have much to do. I wasn't pastor or anything. I was just a friend of the Community.
