Pope Leo is wrapping up his visit to Argentina on Wednesday with a final event expected to draw millions, according to the supplied report from Lujan.
The event is an outdoor Mass at the shrine of Our Lady of Lujan, Argentina's most important Catholic devotional site. Throngs of pilgrims have been gathering there ahead of the Mass.
After Argentina, Leo continues his 12-day South America tour with a visit to Peru. The report describes the Peru visit as an emotional homecoming for the first Peruvian citizen to lead the Catholic Church.
Leo is on a three-nation tour through November 17.
