On Monday, the Vatican and Italian officials said pilgrims to Rome for the 2025 jubilee came from 185 countries, with the majority from Italy, the U.S., Spain, Brazil and Poland.
The 2025 jubilee was opened by the late Pope Francis, who died in April, and closed by Leo, who was elected in May, making him the first American pope.
It was a historical rarity not seen in 300 years for it to be opened by one pope and closed by another. The last jubilee held under two different popes was in the year 1700, when Innocent XII opened the Holy Year that was then closed by Clement XI.
Leo, who has promised to keep Francis' signature policies such as welcoming gay Catholics and discussing women's ordination, echoed his predecessor's frequent criticisms of the global economic system during his remarks on Tuesday.
The markets "turn human yearnings of seeking, traveling and beginning again into a mere business," Leo said.
