Pope Leo XIV Celebrates First Mass, Calls Church to Light the World's "Dark Nights"

First Mass in the Sistine Chapel
Less than 24 hours after his election, Pope Leo XIV—formerly Cardinal Robert Prevost—celebrated his first Mass in the Sistine Chapel, where he was chosen as the 267th pope. Standing before the cardinals who elected him, Leo warned of the moral and spiritual dangers of a faithless world and envisioned the Church as a light during humanity’s “dark nights.”

A Message of Hope and Service
Dressed in modest white and gold vestments, the 69-year-old American-born pope, who spent decades as a missionary in Peru, began his homily with brief remarks in English before continuing fluently in Italian. He vowed to be a “faithful administrator” for the global Church, warning of the consequences of a world that neglects faith—highlighting moral decay, broken families, and societal wounds.

May 18 Inauguration in St. Peter’s Square
The Vatican announced that the pope’s formal inauguration will take place on Sunday, May 18, in St. Peter’s Square. World and religious leaders are expected to attend the historic occasion, similar to Pope Francis’ 2013 inauguration which drew a crowd of around 200,000.

Continuity and Change in the Vatican
For now, Pope Leo XIV will keep senior Vatican officials in place, giving him time to assess leadership before deciding on new appointments. Vatican roles are not permanent and depend on the pope’s discretion.

Election and Immediate Challenges
Leo XIV’s swift election after a two-day conclave follows the death of Pope Francis last month. While conclave details remain confidential, Leo’s selection marks a turning point as the first U.S. pope—breaking assumptions that a superpower nation couldn't lead the global Church. He also holds Peruvian citizenship, bridging both developed and developing worlds.

U.S. Reactions and Political Background
President Donald Trump congratulated the new pope, though Leo has previously criticized Trump and Vice President JD Vance’s policies. His comments—posted under his former name Robert Prevost—reflect a more progressive stance on global issues.

A Social Justice Legacy
Pope Leo’s choice of name alludes to Pope Leo XIII, a leader renowned for his dedication to social justice and labor rights. This could indicate a similar direction for Leo XIV’s papacy.

Hometown Pride in Peru
In Chiclayo, Peru, where Leo served as bishop, Catholics celebrated his election with street processions and church bells, proudly claiming him as one of their own.

A Quiet but Influential Figure
Though shy and rarely interviewed, Leo has held one of the Vatican’s most influential roles—overseeing the appointment of bishops worldwide. That background gives him deep insight into the Church’s global leadership structure.
