The newly elected head of the Catholic Church and the first American to hold the papacy, Pope Leo XIV celebrated his inaugural Mass with the College of Cardinals in the Sistine Chapel on Friday.
Formerly Cardinal Robert Prevost, the Chicago-born cleric, served for decades as a missionary and later Bishop of Chiclayo in Peru before ascending the ranks of the Vatican.
