Pope Francis marks one year at the Vatican

As Pope Francis completes his first year in office, David Willey reports from Rome on the changes that have taken place in the Vatican and the Catholic Church. Back in 1978 - which went down in history as the "year of the three Popes" - I remember meeting a gregarious American priest and journalist who drew up a pithy job description for the leadership of the Catholic Church on the death of Paul VI. "We need a happy, holy man, who smiles!" he said. Now people feel like they finally have that pope.
