The Roman Catholic Church will investigate a life-saving miracle attributed to the late Pope John Paul I, bringing the pontiff who served only 33 days in 1978 one step closer to possible sainthood. His papacy was one of the briefest in history, ended by an apparent heart attack. In 2003, the Vatican’s Congregation for the Causes of Saints opened the way for his beatification, the rank just below sainthood. To qualify, a candidate must have been a martyr or have a miracle attributed to his or her intercession. An inquiry by John Paul’s native diocese of Belluno, Italy, concluded last November without finding evidence of such a miracle. Now another tribunal will consider a man in the Italian region of Apulia who claims he was cured of lymphoma 14 years ago through the intercession of the late pope.
