Cardinal Robert Francis Prevost was elected Pope Leo XIV on Thursday, May 8 — the first pope from the United States.

Smiling and waving while wearing more traditional papal garb than his predecessor — and appearing to hold back tears at certain points — Leo blessed the cheering masses assembled in St. Peter’s Square, proclaiming in confident Italian: “Peace be with you all!”

An Augustinian and a canon lawyer, Prevost spent over a decade ministering in South America before being called back to the U.S. to head the Augustinian Province of Chicago and was later elected prior general of the Augustinian order, serving in that role for a dozen years. He later returned to South America after Pope Francis in 2014 appointed him bishop in Chiclayo, Peru. Francis later called him to Rome in 2023 to head the highly influential Dicastery for Bishops.

Prevost, 69, was born on Sept. 14, 1955, in Chicago. He is of Italian, French, and Spanish descent. He studied at an Augustinian minor seminary and later earned a bachelor of science degree in mathematics from Villanova University in Pennsylvania.

He officially entered the Order of St. Augustine in 1978, making his solemn vows in 1981. He was ordained to the priesthood in June 1982 after studying theology at the Catholic Theological Union of Chicago.

After being ordained, he earned a doctorate in canon law from Rome’s Pontifical College of St. Thomas Aquinas (also known as the Angelicum) in 1987.

Prevost returned to Chicago for a short time in 1987, serving as pastor for vocations and director of missions for the Augustinian Province of Chicago. He was then sent to Peru, where he served the Augustinians in various capacities including as a regional ecclesiastical judge and teacher of canon law in the diocesan seminary for Trujillo, Peru, for 10 years.

After being elected the head of the Augustinian Province of Chicago, Prevost returned to the U.S. in 1999. He was elected prior general of the Augustinians in 2001 and then reelected in 2007, serving as head of the order until 2013.

Pope Francis appointed Prevost as apostolic administrator of Chiclayo, Peru, in 2014, and he was ordained titular bishop of Sufar that same year.

While serving the Church in Peru, Francis made Prevost a member of the Dicastery for the Clergy in 2019 and then a member of the Dicastery for Bishops in 2020. In 2023, Francis made Prevost prefect of the Dicastery for Bishops. In that capacity, Prevost played a key role in the selection process for diocesan bishops around the world and in the investigation of allegations against bishops.

In 2023, Prevost spoke to Vatican News about what he considered to be the “portrait of a bishop.”

“We are often preoccupied with teaching doctrine, the way of living our faith, but we risk forgetting that our first task is to teach what it means to know Jesus Christ and to bear witness to our closeness to the Lord,” he told Vatican News.

“This comes first: to communicate the beauty of the faith, the beauty and joy of knowing Jesus,” he added. “It means that we ourselves are living it and sharing this experience.”

Pope Francis made him a cardinal in a Sept. 30, 2023, consistory.
