Americans gathered in St. Peter’s Square on May 8 to celebrate the election of Pope Leo XIV, the first pontiff from the United States. Born Robert Francis Prevost on Chicago’s South Side, the 69-year-old Augustinian friar was chosen by the College of Cardinals after just two days of conclave. While American flags were scarce among the sea of international banners, those present from the U.S. lingered in the square long after the Holy Father appeared out on the loggia of St. Peter’s Basilica for the first time. They shared prayers, chants, and reflections on the unprecedented moment.  “Never in a million years did I think that the Holy Spirit would send us a beautiful cardinal from Chicago,” said Deacon Steven Marcus, a Maronite Catholic from Florida. “You could tell by his face that he’s filled with the Holy Spirit. He’s filled with love. This is who the Church needs.” Moments after the white smoke rose, the crowd surged toward the front of the basilica.  John Stadeno, a Villanova University graduate from Philadelphia, stood front and center with his friend, John Sanchez of New York, clutching an American flag and wearing a Phillies jersey and a baseball cap. Together they chanted the name of the spiritual father of the new pope’s religious order: “Agostino! Agostino!” John Stadeno, a Villanova University graduate from Philadelphia, stood front and center during the announcement of the 267th pontiff, Pope Leo XIV, on May 8, 2025, in St. Peter’s Square.

He’s worked hard as a missionary, as a bishop. He’ll do a good job.” Sanchez added: “God bless the new Pope Leo XIV and God bless the U.S.A.” Brother Benedict Mary Bartsch, OP, a 29-year-old Dominican from Hawaii studying at the Pontifical Academy of St. Thomas Aquinas — where the new pope is also an alumnus — expressed his awe at witnessing the event firsthand. “It’s an amazing opportunity to be here in Rome, to be at the heart of the Church, and praying all these days for the cardinals and for the election of the new Holy Father. And to be here in the square when it actually happened, it’s just amazing.” Brother Benedict Mary Bartsch, OP, a 29-year-old Dominican from Hawaii studying at the Pontifical Academy of St. Thomas Aquinas in Rome — where the Pope Leo XIV is also an alumnus — expressed his awe at witnessing the announcement of the first U.S.-born pope firsthand on May 8, 2025, in St. Peter’s Square.

You could see that he understood the sort of weight, the burden that comes with the office, with the Petrine office.” Andres Novoa, 33, from the Archdiocese of Miami, held up one of the few American flags in the square. “It feels unbelievable,” he said. “The Church needs a lion. The Church needs to realize that Christ is the Lion of Judah. The Church needs to assert herself as the mother and teacher, you know, that is what the world needs. And the Church is not here to hurt anyone. It’s here to give everyone salvation.” Andres Novoa, 33, from the Archdiocese of Miami, held up one of the few American flags in St. Peter's Square after the announcement of Pope Leo IV as the 267th leader of the Catholic Church on May 8, 2025. “It feels unbelievable,” Novoa said.

And now, the last thing we expected was an American pope.” David Solheim, an Eastern Orthodox Christian from Phoenix, traveled to Rome for the conclave. “I came out to Rome specifically for the conclave, something I always wanted to do. Like a bucket list item,” he said. “And never thought that my first conclave would be the first American pope.” He noted the pope’s initial reaction: “You could tell he wasn’t expecting it. He was nervous. Like, I think all of us would be up there. He seems like a genuine shepherd and pastor and I look forward to what the future holds for the Church.” Jerry Grogan, holding an American flag before the announcement, expressed his pride: “It’s so exciting to have someone from Chicago, my hometown, to represent the Catholic Church. I’m so proud.”Jerry Grogan, holding an American flag before the announcement of the first U.S.-born pope, Leo XIV, on May 8, 2025, expressed his pride: “It’s so exciting to have someone from Chicago, my hometown, to represent the Catholic Church.
