ATLANTA—The spacious office on the third floor of the Chancery is mostly empty, awaiting the belongings and activities of its new owner. In the time since his announcement May 18 as the new auxiliary bishop of Atlanta, Bishop Bernard E. “Ned” Shlesinger III has moved to Atlanta from Philadelphia, where he had served as the director of spiritual formation at St. Charles Borromeo Seminary for the past few years. His new office has a computer and furniture but not much more.
