World Leaders Gather for Pope Leo XIV's Inaugural Mass

Leaders from across the globe converge to celebrate the inauguration of Pope Leo XIV, marking a significant moment in the Roman Catholic Church.

On the morning of May 18, 2025, St. Peter's Square in Vatican City was a bustling hub, as numerous world leaders came together to witness the inaugural Mass of Pope Leo XIV. The occasion heralded the beginning of a new papacy for the leader of 1.4 billion Roman Catholics.

Among those present were United States Vice President JD Vance and Secretary of State Marco Rubio. Both expressed their congratulations and pride in Pope Leo’s American roots, although the nature of future relations between the Vatican and the U.S. remains uncertain—a sentiment highlighted by previous criticisms levied against the vice president on social media by an account allegedly linked to the new pope.

From Ukraine, President Volodymyr Zelensky marked the occasion with a warm exchange with Pope Leo last week regarding ongoing cease-fire initiatives amid the country's wartime struggles. Following the inaugural Mass, Pope Leo also offered to take the lead in orchestrating peace discussions between Ukraine and Russia, extending an olive branch during turbulent times.

Canada's Prime Minister Mark Carney, unable to attend the funeral of Pope Francis due to election obligations, expressed hope for a partnership with Pope Leo in pursuing values of solidarity and sustainability.

Peru’s President Dina Boluarte led a delegation celebrating her country’s connection to Pope Leo, who spent significant time in Peru before his papal election. She praised the spiritual leader's deep commitments to those in need, calling it an indelible mark on Peru’s heart.

Italy's leadership was represented by Prime Minister Giorgia Meloni and President Sergio Mattarella, both of whom emphasized ongoing collaboration with the Vatican in various initiatives including the ethical development of artificial intelligence.

A comprehensive list of attending dignitaries also included Australia’s Prime Minister Anthony Albanese, Belgium’s Prime Minister Bart De Wever, European Commission President Ursula von der Leyen, and many more from around the globe, showcasing the significance of the event.

As the world observes this new chapter in the Roman Catholic Church, the presence of such diverse leaders illustrates the potential for global cooperation led by the Vatican under Pope Leo XIV's guidance.
