On May 9, 2025, Pope Leo XIV, formerly Cardinal Robert Francis Prevost, celebrated his first Mass as the 267th pontiff of the Roman Catholic Church in the Sistine Chapel. This significant event followed his historic election as the first American pope, marking a new chapter in the Church's history. In his homily, the Pope lamented society's increasing focus on technology, wealth, and success over spiritual values. He called for a renewed evangelization effort, urging the Church to be a beacon of light in a world often overshadowed by materialism and moral uncertainty.

Born in Chicago and holding dual U.S.-Peruvian citizenship, Pope Leo XIV has a rich background in missionary work, having served extensively in Peru. His election came after a swift conclave, where 133 cardinal electors from 70 countries convened. The conclave concluded in just over 24 hours, with Pope Leo XIV securing the necessary two-thirds majority on the fourth ballot. Cardinal Fernando Chomalí of Chile described the rapid consensus as a "miracle of the Holy Spirit."

During his inaugural Mass, Pope Leo XIV addressed the College of Cardinals, expressing gratitude for their trust and emphasizing the weight of his new responsibility. He spoke in both English and Italian, highlighting the importance of unity and the Church's mission to spread the Gospel with joy. He stated, "You have called me to carry that cross and to be blessed with that mission, and I know I can rely on each and every one of you to walk with me."

Pope Leo XIV's choice of name pays homage to Pope Leo XIII, known for his advocacy of workers' rights and social justice. This selection signals a potential continuation of Pope Francis's emphasis on social issues and inclusivity within the Church. Notably, Pope Leo XIV has chosen to maintain a modest lifestyle, opting for simple black shoes and residing in his previous accommodations rather than the Apostolic Palace. His formal inauguration is scheduled for May 18, with his first general audience planned for May 21.
