Sisters of Mother Teresa's Missionaries of Charity walk up the steps to take their seats beneath St. Peter's Basilica for a thanksgiving Mass following Mother Teresa's canonization, in St. Peter's Square, at the Vatican, Monday, Sept. 5, 2016. Elevating the "saint of the gutters" to one of the Catholic Church's highest honors, Pope Francis on Sunday praised Mother Teresa for her radical dedication to society's outcasts and her courage in shaming world leaders for the "crimes of poverty they themselves created."
