Pope Francis speaks to journalists during a press conference on the plane after his visit to Krakow for the World Youth Days, on July 31, 2016. Pope Francis celebrated mass on July 31, 2016 with over 1.5 million pilgrims in a vast sun-drenched field in Poland, wrapping up an emotionally charged trip with some choice technological metaphors. In a nod to today's internet-dominated world, Francis urged the faithful, who had travelled to Poland from all over the world, to "download the best link of all, that of a heart which sees and transmits goodness without growing weary". / AFP PHOTO / POOL / Filippo MONTEFORTEFILIPPO MONTEFORTE/AFP/Getty Images
