Pope Francis pushes open the Holy Door of St. Peter's Basilica, formally launching the Holy Year of Mercy, at the Vatican, Tuesday, Dec. 8, 2015. The 12-month jubilee emphasizes what has become the leitmotif of his papacy: to show the merciful and welcoming side of a Catholic Church more often known for its moralizing and judgment.
