Faithful pose with a figure of the Virgin as they wait for Pope Francis to celebrate mass at Nu Guazu field in Asuncion, Paraguay, Sunday, July 12, 2015. On the final day of his three-nation South American tour, Francis sought to offer a message of hope and mission to the residents of the Banado Norte shantytown and to hundreds of thousands of people gathered for his farewell Mass on the same swampy field where St. John Paul II proclaimed Paraguay's first saint nearly 30 years ago.
