Pope Francis arrives in St. Peter's square to visit a nativity scene after he celebrated a New Year's Eve vespers service in St. Peter's Basilica at the Vatican, Tuesday, Dec. 31, 2013. Pope Francis has used his traditional year-end prayer service of thanksgiving to urge people to ask themselves: Did they spend 2013 to further their own interests or to help others? That's what we all should "courageously" consider as New Year's celebrations get under way, the pontiff said, as he led the service in St. Peter's Basilica on Tuesday evening.
