On May 8, 2025, the Catholic Church elected its 267th pontiff: Robert Francis Prevost, aged 69, now known as Pope Leo XIV. This discreet and moderate American cardinal succeeds Pope Francis, signaling continuity and stability within the Vatican. His swift election in the fourth round of the conclave reflects the College of Cardinals' desire for a smooth transition.

An American Pope for the Catholic Church

Born in Chicago, to a Franco-Italian father and a Spanish mother, Robert Francis Prevost brings international roots and a pastoral spirit. A member of the Order of Saint Augustine, he served for many years as a missionary in Peru, mastering several languages including Spanish, Italian, and English.

Appointed cardinal in 2023 by Pope Francis, Prevost has been seen as a man of listening, prudence, and reform-minded moderation.

By choosing the name Leo XIV, he aligns himself with a papal lineage marked by peace, dialogue, and institutional wisdom. His first words from the balcony of St. Peter’s Basilica were simple and powerful:

“Peace be with you all!”

Origins and Formation

Born into a culturally diverse American family, Robert Prevost grew up in Dolton, a suburb of Chicago, alongside his brothers Louis Martín and John Joseph. His father, Louis Marius Prevost, of French and Italian descent, was a school principal and an officer in the U.S. Navy during World War II. His mother, Mildred Agnes Martinez, a highly active librarian in their parish, descended from Creole, Haitian, and Spanish lines, including African-descendant ancestors. This makes Pope Leo XIV the first pope of Sub-Saharan African descent since antiquity.

The paternal branch of his family also includes a French grandmother, Suzanne Fontaine, born in Le Havre and immigrated to New York in 1915.

A polyglot, Pope Leo XIV speaks English, Spanish, Italian, French, and Portuguese. He is also proficient in German and Latin for reading purposes. He earned a bachelor's degree in mathematics from Villanova University in 1977, before joining the Augustinian order. He made his solemn vows in 1981 and was ordained a priest in 1982 in Rome. He continued his studies in Canon Law at the Pontifical University of St. Thomas Aquinas, obtaining his degree in 1984.

Missionary Ministry and Canonical Commitment

Sent to Peru in 1985, Pope Leo XIV held various positions: Chancellor of the Chulucanas Prelature, Director of the Augustinian Seminary of Trujillo, Canon Law professor, Prefect of Studies, Ecclesiastical Court member, and Pastor of a quasi-parish in a disadvantaged neighborhood.

Returning to the United States in 1987, he worked on promoting vocations before returning to Peru in 1988 for a ten-year ministry. In 1998, he was elected Provincial of the Midwest American Augustinian Province and moved back to Chicago.

In 2001, he was elected Prior General of the Augustinian Order, a position he held until 2013 after a renewed mandate. Between 2013 and 2014, he held various roles in the Augustinian Province, including Director of Studies and Provincial Vicar.

A controversy regarding the housing of a priest accused of abuse in a residence near a high school emerged in 2000 but was refuted by several sources, including journalist Pedro Salinas, as an attempt to discredit him by those opposed to his positions against extremist organizations.

Bishop in Peru

On November 3, 2014, Pope Francis appointed him Apostolic Administrator of Chiclayo and Titular Bishop of Sufar. He received episcopal ordination on December 12, 2014, and became Bishop of Chiclayo in September 2015. That same year, in accordance with Peruvian law, he obtained Peruvian citizenship.

He chose the motto "In illo uno unum," drawn from Saint Augustine's commentary on Psalm 127: "Although we are many, we are one in Christ." His coat of arms includes the seal of his order, a Marian fleur-de-lis, and symbols of the Gospel.

From 2020 to 2021, he also served as interim bishop of the Diocese of Callao. A member of the Peruvian Episcopal Conference, he held various responsibilities, including Vice-President and President of the Education and Culture Commission.

Prefect of the Dicastery and Cardinal

In January 2023, he succeeded Marc Ouellet as head of the Dicastery for Bishops and President of the Pontifical Commission for Latin America. Pope Francis elevated him to the cardinalate during the consistory on September 30, 2023, assigning him the title of Santa Monica.

On February 3, 2025, he intervened on social media to correct a controversial interpretation by an American political figure about the hierarchy of Christian love. On February 6, he was promoted to Cardinal-Bishop of the Suburbicarian Diocese of Albano.

Papal Election

The conclave of May 8, 2025, led to his election on the fourth ballot. He became the first pope from the United States and Peru, as well as the first Augustinian pope in centuries. Although he was not a frontrunner, his profile as a mediator and loyal disciple of Pope Francis made him a consensus candidate. He chose the name Leo XIV, in reference to Pope Leo XIII and his social doctrine.

His first public appearance from the loggia of St. Peter’s Basilica marked a return to some traditional symbols, such as the mozzetta and red stole, which his predecessor had omitted. He first addressed the crowd in Italian and Spanish before giving his Urbi et Orbi blessing in Latin.

The Vatican emphasized that he was the first pope born in the United States, the first North American citizen, the first English-speaking pope since Adrian IV, and the second pope from the Americas after Francis.

Beginnings of the Papacy

On May 9, 2025, Pope Leo XIV celebrated his first papal mass in the Sistine Chapel, denouncing the hold of "false securities" like money, technology, and the pursuit of power. On May 11, he presided over a mass in honor of the Virgin Mary from the loggia of St. Peter's. The following day, he met with the global press.

The inaugural mass of his papacy is scheduled for May 18, 2025.

Distinctions and Coat of Arms

His coat of arms includes a fleur-de-lis, a pierced heart in flames, and an Evangelist symbol, all accompanied by his motto: "In illo uno unum." Like his predecessors, Pope Leo XIV becomes ex officio Grand Master of the pontifical chivalric orders: the Order of Christ, the Order of the Golden Spur, the Order of Pius IX, the Order of Saint Gregory the Great, and the Order of Saint Sylvester.
