This handout picture released by L'Osservatore Romano shows Pope Francis (L) shaking hands with a clergyman during a blessing ceremony of new houses for the poor and elderly built by Catholic charity Caritas, at Campus Misericordiae on July 31, 2016 in Brzegi as part of the World Youth Days (WYD). Pope Francis celebrated mass on July 31, 2016 with over 1,5 million pilgrims in a vast sun-drenched field, wrapping up an emotionally charged trip to Poland with some choice technological metaphors. In a nod to today's internet-dominated world, Francis urged the congregation, 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 / OSSERVATORE ROMANO / Handout / RESTRICTED TO EDITORIAL USE - MANDATORY CREDIT "AFP PHOTO / OSSERVATORE ROMANO / HANDOUT" - NO MARKETING - NO ADVERTISING CAMPAIGNS - DISTRIBUTED AS A SERVICE TO CLIENTS HANDOUT/AFP/Getty Images
