Pope Francis walks to the altar to celebrate mass at the Las Palmas air base in Lima on January 21, 2018.
Pope Francis was preparing to wrap up his Latin American trip on Sunday with a mass at the air base where a million faithful were expected to hear him speak. On the last day of a week-long trip that has taken him to six cities in Chile and Peru, the 81-year-old pontiff began the day by delivering a homily to 500 nuns, as well as meeting the bishops of Peru.
