Pope Leo XIV celebrated his first Mass in the Sistine Chapel where he was elected less than 24 hours earlier, warning of the dangers caused by a lack of faith and hoping the Catholic Church could be a beacon lighting the world's "dark nights".

P olitical figures around the world have congratulated Robert Francis Prevost, now known as Pope Leo XIV, after his election on Thursday, May 8, as pontiff of the Roman Catholic Church. Hailing from Chicago and a dual U.S.-Peru national, Prevost is the first North American Pope and second from the Americas, after his late predecessor Francis.

Leo’s ascent occurred with remarkable speed. Just over two years ago, he’d been one of the church’s 5,400 bishops — a role with no global visibility.
