Pope Francis (R) leads mass near the statue of Our Lady of Asuncion in Luque, on the outskirts of Asuncion, Paraguay, July 12, 2015. The Argentine pontiff, who is wrapping up his three-country tour of South America, has made defending the poor a major theme of his "homecoming" trip, which also took him to Ecuador and Bolivia, ranked among Latin America's poorest countries.
