Pope Francis paid a somber visit to the Nazi German death camp of Auschwitz-Birkenau, becoming the third consecutive pontiff to make the pilgrimage to the place where Adolf Hitler’s forces killed more than 1 million people, most of them Jews. Francis entered the camp on foot, walking slowly beneath the notorious gate at Auschwitz bearing the cynical words “Arbeit Macht Frei.” He prayed silently for more than 15 minutes before meeting with several survivors of the camp, greeting them one by one, shaking their hands and kissing them on the cheeks.
