Pope Francis, back to camera is helped with his his skull cap as he arrives to celebrate a mass in Asuncion, Paraguay Sunday, July 12, 2015. Hundreds of thousands have gathered on a huge swampy field called Nu Guazu inside a military base to attend the mass. At this very spot, Pope John Paull II in 1988 canonized Paraguay's first saint, Roque Gonzalez de Santa Cruz, a Jesuit priest that was a missionary to the Guarani people. (AP Photo/Gregorio Borgia)
