Pope Francis poses for pictures with faithful at the end of a Palm Sunday service in St. Peter's Square, at the Vatican, Sunday, April 13, 2014. Pope Francis, marking Palm Sunday in a packed St. Peter's Square, ignored his prepared homily and spoke entirely off-the-cuff in a remarkable departure from practice. Later, he hopped off his popemobile to pose for "selfies" with young people in the crowd. In his homily, Francis called on people, himself included, to look into their own hearts to see how they are living their lives.
