Pope Leo XIV’s Inaugural Mass Draws Global Leaders to Rome

The inauguration of Pope Leo XIV attracted heads of state and royalty worldwide, signaling a renewed interest in the Catholic Church's role in global affairs.

On May 18, 2025, St. Peter's Square was awash with leaders from various countries as Pope Leo XIV commenced his pontificate with an inaugural Mass. The ceremony not only marked a significant religious milestone but also served as a platform for international diplomacy and discussions on pressing global issues.

United States Vice President JD Vance and Secretary of State Marco Rubio were present, expressing appreciation for Pope Leo’s American roots. However, there remains uncertainty regarding their relationship, particularly following earlier criticisms from a social media account associated with Leo concerning Vance's view of Catholic doctrine.

In Ukraine, President Volodymyr Zelensky was among those engaging in dialogue with the new pontiff. After a phone call that was characterized as “very warm and truly substantial," Zelensky noted that both leaders discussed plans for a ceasefire in the ongoing conflict, with Pope Leo expressing a willingness to act as a mediator for peace talks in the Vatican.

Canadian Prime Minister Mark Carney, a devout Catholic, underscored his eagerness to collaborate with Pope Leo, particularly on initiatives fostering solidarity and justice following his previous absence from Pope Francis’ funeral. His statements herald the possibility of intensified Vatican-Canada relations.

From Peru, President Dina Boluarte led a delegation celebrating Pope Leo's significant contributions during his years there. The connection to his ancestral homeland was reciprocated with Boluarte acknowledging the profound impact of Leo's compassion on the nation.

Italy's leadership was represented by Prime Minister Giorgia Meloni and President Sergio Mattarella, who emphasized the Vatican's influence on ethical issues, including the use of artificial intelligence, while also aligning with Leo’s spiritual aspirations that aim to follow those laid by Pope Francis.

The gathering also included notable figures from Australia, Belgium, the European Union, France, Germany, Israel, Lebanon, Lithuania, the Netherlands, Nigeria, Portugal, and the United Kingdom, reflecting a collective hope for collaborative efforts with the Vatican under Pope Leo's guidance.

These interactions set the stage for the future relationship between the Vatican and world leaders, driven by concerns such as warfare, sustainable development, and moral ethics in a rapidly evolving world. As Pope Leo XIV steps into his pontificate, the world watches closely to see how his leadership will shape the Catholic Church’s role on the global stage.
