FILE - In this 2008 file photo, Argentina's Cardinal Jorge Mario Bergoglio, second from left, rides the subway in Buenos Aires, Argentina. Bergoglio, who became pope in 2013 and took the name Francis, was known for taking the train. Cardinal Bergoglio never followed the footsteps of so many fellow Roman Catholic leaders of his rank, who sought to raise their profiles, along with funds for missions back home, by networking within the deeply influential and well-resourced U.S. church.
