Pope Leo XIV was formally enthroned as the head of the Roman Catholic Church in a grand ceremony at St Peter’s Basilica on Sunday, May 18, drawing an estimated 150,000 people and a host of global leaders to the Vatican.
The newly elected Pontiff, born Robert Prevost in Chicago and the first North American pope, presided over a Mass that blended ancient tradition with modern diplomacy.
In a powerful homily broadcast worldwide, Pope Leo called for unity, criticised economic inequality, and pledged to lead “without ever yielding to the temptation to be an autocrat.”
“I was chosen, without any merit of my own, and now, with fear and trembling, I come to you as a brother,” he told the vast crowd.

Among the many international dignitaries in attendance was Ecumenical Patriarch Bartholomew, who travelled to Rome for the enthronement.
The Patriarch was accompanied by high-ranking clergy including the Metropolitans of Pisidia and Italy, and the Codographer of the Holy and Sacred Synod.
He also held a meeting with the delegation from the Patriarchate of Alexandria during the event. A private meeting between the Patriarch and Pope Leo is scheduled for Monday, May 19.
Greek Minister of Education, Religious Affairs and Sports Sofia Zacharaki, leading the Greek delegation, held a brief meeting with the Pope following the enthronement.
She congratulated him and praised his message of “love and solidarity,” particularly noting his emphasis on “the spiritual empowerment and inspiration of young people.” The Greek delegation also included Deputy Foreign Minister Yannis Loverdos.
Australian Prime Minister Anthony Albanese also attended the ceremony and was among the many leaders who briefly met the Pope after the Mass.
The ceremony was rich in symbolism. Before the Mass, Pope Leo descended to venerate the bones of St Peter, the first bishop of Rome. He then received the pallium, a vestment signifying his role as shepherd, and the Fisherman’s Ring, a gold signet marking his new office.
The crowd erupted in applause as the Pope made his first tour of St Peter’s Square in the Popemobile, waving to pilgrims and dignitaries from across the globe.
