Pope Leo XIV’s Inaugural Mass on May 18: A Historic Moment for American Catholics

The Inaugural Mass of Pope Leo XIV Set for Sunday, May 18

St. Peter’s Square in Rome will be the stage for a historic event: the inaugural Mass of Pope Leo XIV, the first American-born pope in history, will take place on Sunday, May 18, 2025. Officially announced by the Vatican, this solemn ceremony will mark the beginning of his public ministry and will draw worshipers from around the world.

Just ten days after his election as head of the Catholic Church, Robert Francis Prevost, now Pope Leo XIV, will celebrate this Mass in the presence of cardinals, world leaders, religious authorities, diplomats, and thousands of pilgrims — especially from the United States, his home country.

A Powerful Symbol for American Catholics

The election of Leo XIV has sparked deep emotion and hope among American Catholics. Never before has a U.S. citizen ascended to the Chair of Saint Peter. His inaugural Mass is therefore a once-in-a-lifetime moment for believers across America, whether they attend in Rome or follow from afar, united in prayer with their new pope.

A Week of Key Events Before the Mass

Pope Leo XIV has already begun his ministry with a private Mass in the Sistine Chapel, where he called believers to return to faith and resist modern idols like “technology, money, success, power, and pleasure.” He will meet with cardinals, lead the Regina Caeli prayer on Sunday, receive media representatives and diplomats, and host his first General Audience on Wednesday, May 21.

How to Watch the Inaugural Mass from the U.S.

Catholic networks like EWTN, as well as Vatican News, will broadcast the Mass live. Many U.S. parishes will organize watch parties or special services. Several websites will also offer livestream access to the ceremony for American viewers.
