The pope’s words came in a homily during Mass in St. Peter’s Square May 12, when he canonized the first Colombian saint, as well as a Mexican nun and some 800 Italians martyred by Ottoman Turks in the 15th century.

Mexico’s St. Maria Guadalupe Garcia Zavala (1878-1963), the pope said, gave up a “comfortable life to follow the call of Jesus, taught people to love poverty, in order the more to love the poor and the sick.”

“How much damage does the comfortable life, well-being, do,” the pope added, looking up from his prepared text. “The gentrification of the heart paralyzes us.”
