Video: Pope Benedict's influence will linger

Pope Benedict XVI greets the youth in front of a huge Jesus Christ portrait in Krakow in this May 27, 2006 file photo. Pope Benedict said on February 11, 2013 he will resign on Feb 28 because he no longer has the strength to fulfill the duties of his office, becoming the first pontiff since the Middle Ages to take such a step.
