Pope Leo XIV presided over his inaugural Mass on Sunday morning in St. Peter’s Square, attended by an estimated 150,000 people, including global leaders and prominent church officials. This service marked the beginning of his papacy as the first American pope, succeeding Pope Francis, who passed away in April. Amid the congregation were notable figures, such as Vice President JD Vance, Secretary of State Marco Rubio, President Volodymyr Zelensky of Ukraine, and Prime Ministers from Canada and Australia.

During his homily, Pope Leo addressed the urgency of inclusivity and unity within the Catholic Church, echoing sentiments expressed by his predecessor. He conveyed that the cardinals who elected him wanted a shepherd to preserve the Church’s rich heritage while also confronting modern issues. “I come to you as a brother, with fear and trembling,” he stated, emphasizing the need for unity as a familial bond within the Church.

In his remarks, Leo highlighted the diverse challenges facing society today. From conflicts in Ukraine and Gaza to the implications of artificial intelligence, he called for compassion towards vulnerable populations while reflecting upon the suffering caused by wars and economic disparities.

The inauguration was marked by traditions, including the ceremonial ride through St. Peter’s Square in a popemobile, where the pope waved to the enthusiastic crowd. He also prayed in Latin, seeking guidance as the successor to St. Peter.

Given the complex dynamics within the Catholic community, particularly in the U.S., Leo's election has sparked hope for a potential shift towards a greater emphasis on inclusivity and cooperation among factions within the Church. JD Vance’s attendance signifies a possible reset in the church’s relationship with conservative American Catholics, who had felt estranged from the previous papacy's stances.

As Leo seeks to navigate today’s pressing issues—from economic inequity to international conflicts—his message will test the resolve of global Catholicism to uphold unity amid diversity, fostering a spirit of acceptance and shared responsibility among the faithful. This inaugural Mass is viewed as a pivotal moment that may shape the direction of the church in the years to come, amid a backdrop of historical reverence and modern challenges.
