Pope Francis caresses a guide dog during a private audience to members of the media on March 16, 2013 at the Paul VI hall at the Vatican. Pope Francis called for &quot;a poor Church for the poor&quot;, saying he chose his papal name because St Francis of Assisi was &quot;a man of poverty and a man of peace&quot;.
