Pope Leo XIV, born Robert Francis Prevost in Chicago on September 14, 1955, is the 267th pope of the Catholic Church and the first pope from the United States. He studied mathematics and philosophy before joining the Augustinian religious order, becoming a priest, serving for many years in Peru, and later taking senior roles in the Vatican. As of October 12, 2026, he is 71; the Vatican has said he is expected to undergo surgery this week to remove a small lung nodule, with recovery expected to take about a week.
Pope Leo XIV, whose birth name is Robert Francis Prevost, made history on May 8, 2025, when he was elected pope following the death of Pope Francis. Born and raised in the United States, he became the first pope from the country and the first member of the Augustinian religious order to lead the Catholic Church.
His journey to the Vatican was shaped by education, religious life, and decades of pastoral work in Peru. Before his election, he served as a missionary, bishop, leader of the worldwide Augustinian order, and head of the Vatican’s Dicastery for Bishops.
As of October 12, 2026, Pope Leo XIV is 71 years old. The latest development concerning his health is that he announced plans to undergo surgery to remove a small, well-localized lung nodule. The Vatican has said recovery is expected to take about a week, although the nature of the growth has not been publicly disclosed.
Who Is Pope Leo XIV?
Pope Leo XIV is the 267th pope of the Catholic Church. He was elected on May 8, 2025, during a conclave held in the Vatican after Pope Francis died in April 2025.
His election was historic for two reasons. He was the first pope born in the United States and the first pope from the Order of Saint Augustine, commonly known as the Augustinians. His years of service in Peru also gave him extensive experience of the Church in Latin America.
The name Leo XIV was chosen by Prevost after his election. A pope’s chosen name can signal spiritual influences and priorities, although the meaning of a particular choice should be explained through the pope’s own words and official accounts rather than speculation.
Pope Leo’s background differs from that of many previous popes because his early life was rooted in Chicago, while much of his ministry developed in Peru and in the international structure of the Catholic Church.

Robert Francis Prevost was born on September 14, 1955, in Chicago, Illinois. He grew up in a Catholic family with two brothers and attended Catholic schools before pursuing university studies.
His early education and family environment helped shape his religious formation, but his path to the papacy was not immediate. He first studied at university, then entered the Augustinian order in 1977. Years of theological study, parish work, missionary service, and leadership followed before he became a bishop and later a cardinal.
His life story is therefore not simply one of a Chicago-born priest rising through the Vatican. It is also the story of a religious leader whose professional and pastoral experience extended across North America, Europe, and South America.
Who Are Pope Leo XIV’s Parents and Family?
Pope Leo XIV’s parents were Louis Marius Prevost and Mildred Agnes Martínez. According to the Vatican’s official biography, both were born in Chicago and later settled in Dolton, Illinois.
His father served in the United States Navy during the Second World War before entering education. He worked as a teacher and later held school leadership roles. His mother worked as a school librarian and was active in parish life with her husband.
Leo has two brothers, Louis Martín Prevost and John Joseph Prevost. The family’s Catholic faith formed part of his upbringing, and his childhood education included Catholic schools and a minor seminary run by the Augustinians.
Although he now occupies one of the world’s most visible religious offices, the pope’s family background was rooted in an ordinary American community. His parents’ work in education and their involvement in parish life are documented in the Vatican biography, which is the most authoritative starting point for these personal details.
The pope has not publicly shared every aspect of his private family life, and not all personal details are relevant to his official role. Claims about family relationships or private circumstances should be checked against credible sources rather than repeated from social media.
Pope Leo XIV’s Education
Pope Leo XIV pursued a combination of academic and religious studies before his ordination.
Early Schooling
Prevost attended Saint Mary of the Assumption School and later Saint Augustine Seminary High School in Holland, Michigan. His secondary-school years included student leadership and extracurricular activities.
His education in Catholic institutions connected academic study with religious formation. After completing school, he continued to university rather than immediately entering full-time ministry.
Villanova University
Prevost attended Villanova University in Pennsylvania, where he earned a bachelor’s degree in mathematics in 1977. He also studied philosophy.
His mathematics degree stands out in public biographies because it was not the most obvious preparation for a future church leader. However, it was part of a wider education that later included philosophy, theology, and canon law.
Catholic Theological Union
After entering the Augustinian order, Prevost studied theology at the Catholic Theological Union in Chicago. He received a theology degree in 1982, according to biographical accounts of his formation.
This period helped prepare him for priesthood and pastoral service, combining academic study with the spiritual commitments of religious life.
Pontifical University of Saint Thomas Aquinas
Prevost continued his studies in Rome at the Pontifical University of Saint Thomas Aquinas, commonly called the Angelicum. He specialized in canon law, the legal system governing the Catholic Church.
He received a licentiate in canon law in 1984 and completed doctoral work on the role of a local prior in the Augustinian order. His canon-law background later became relevant to his leadership and administrative responsibilities within the Church.
These academic qualifications helped equip him for roles that required both pastoral understanding and knowledge of Church governance.
How Pope Leo XIV Began His Religious Career
Prevost entered the novitiate of the Order of Saint Augustine on September 1, 1977. He made his first profession of vows on September 2, 1978, and his solemn vows on August 29, 1981.
He was ordained a priest on June 19, 1982, at the Augustinian College of Saint Monica in Rome. Ordination marked the beginning of his formal priestly ministry, but his career would soon take him far beyond the United States.
The Augustinians emphasize community life, service, and the spiritual tradition associated with Saint Augustine of Hippo. Prevost’s long membership in the order became central to his identity, and he eventually served as its worldwide leader.
Before his election as pope, he had spent decades in pastoral and administrative work. That experience included parish service, formation of future priests and religious, diocesan leadership, and senior responsibilities in Rome.
Pope Leo XIV’s Missionary Years in Peru
One of the defining chapters of Prevost’s life was his service in Peru, where he worked as a missionary and later became a bishop.
In 1985, he was sent to the Augustinian mission in Chulucanas, in northern Peru. He worked in parish ministry and diocesan administration before returning to the United States for a period of service in his religious province.
In 1988, he returned to Peru and took on responsibilities in Trujillo. His work included helping form Augustinian candidates, serving as a prior, teaching at a major seminary, and working in parish and diocesan roles.
These years gave him experience of local Church life in a country where Catholicism plays a major social and cultural role. They also involved practical responsibilities beyond preaching, including education, formation, administration, and pastoral care.
In 2014, Pope Francis appointed Prevost apostolic administrator of the Diocese of Chiclayo, Peru. He was ordained a bishop in December of that year and was appointed bishop of Chiclayo in September 2015.
His work in Peru continued until he was called to Rome in 2023 to lead the Dicastery for Bishops. His years in the country became an important part of his public identity, and he acquired Peruvian citizenship by naturalization in 2015.
His Rise Through the Catholic Church
Prevost’s progression through the Church involved several major leadership appointments.
- 1999: Elected provincial prior of the Augustinian province based in Chicago.
- 2001: Elected prior general of the Order of Saint Augustine, becoming its worldwide leader.
- 2007: Re-elected prior general for a second term.
- 2014: Appointed apostolic administrator of Chiclayo, Peru.
- 2015: Appointed bishop of Chiclayo.
- 2023: Appointed prefect of the Dicastery for Bishops and president of the Pontifical Commission for Latin America.
- September 2023: Created a cardinal by Pope Francis.
- May 8, 2025: Elected pope and took the name Leo XIV.
As prefect of the Dicastery for Bishops, Prevost had a significant role in the Church’s process of evaluating candidates for episcopal appointments. The position gave him experience with Church leadership around the world and brought him into closer contact with senior Vatican officials.
His election as pope followed years of pastoral, administrative, and international service. While the outcome of a papal conclave cannot be reduced to a single factor, his experience in religious leadership and across different cultures formed an important part of his professional background.
Why Did Robert Prevost Choose the Name Leo XIV?
After his election, Robert Prevost took the papal name Leo XIV. The number XIV indicates that he is the fourteenth pope to use the name Leo.
Papal names often carry historical and spiritual associations. One notable predecessor was Leo XIII, pope from 1878 to 1903, who is remembered in part for Rerum Novarum, an influential encyclical on workers and social conditions. That history provides context for the name, but the exact significance of Leo XIV’s choice should be attributed to his own explanations when available.
In his first public appearance as pope, Leo XIV emphasized peace and addressed the crowd gathered in St. Peter’s Square. His opening message and choice of name were closely watched as early indications of how he might approach the papacy. They should not, however, be treated as a complete blueprint for all his future decisions.
What Has Pope Leo XIV Said About His Mission?
In his first address after election on May 8, 2025, Leo XIV called for peace and presented himself as a pastor committed to the Church’s mission. He also acknowledged Pope Francis, whose death had led to the conclave.
His background in the Augustinian order is another important part of his approach. The order’s spiritual tradition emphasizes community, the search for God, and unity among Christians. Leo’s episcopal motto, In Illo uno unum, is associated with the idea that Christians, though many, are one in Christ.
As pope, his statements and decisions carry institutional significance for Catholics worldwide. His priorities are best understood by following official speeches, Vatican documents, and actions rather than assuming that his biography alone predicts every policy or position.
Pope Leo XIV’s Latest Health Update: Planned Lung Surgery
On October 11, 2026, Pope Leo XIV announced that he would undergo surgery to remove a small, well-localized lung nodule discovered during a recent medical examination. Reuters and the Associated Press reported the announcement, and the Vatican said his recovery was expected to take about a week.
The nature of the nodule has not been publicly disclosed. It would therefore be inaccurate to describe it as cancerous or benign without further medical information from the Vatican or his doctors.
The planned procedure is a current development in his papacy, but it does not change the biographical facts about his age, education, family, or path to office. Any later information about the surgery or his recovery should be taken from official Vatican communications and reputable news outlets.
The pope is scheduled to make a pastoral visit to Uruguay, Argentina, and Peru beginning November 6, 2026, according to Reuters’ report. Whether that itinerary changes will depend on his medical recovery and any subsequent official announcements.
Why Pope Leo XIV’s Background Matters
Pope Leo XIV’s biography offers a useful picture of the international nature of modern Catholic leadership. He was born in the United States, educated in American institutions, formed as an Augustinian, served for many years in Peru, and worked in senior Vatican roles before becoming pope.
His background brings together several experiences:
- American roots: He is the first pope born in the United States.
- A religious-order tradition: He is the first Augustinian to become pope.
- Missionary experience: His years in Peru included parish work, education, and leadership.
- Church administration: His Vatican role involved the selection and appointment process for bishops.
- International service: His work crossed national and cultural boundaries long before his election.
These details help explain the path that brought him to the papacy without reducing his election to nationality or a single career milestone. The pope’s decisions and public statements will continue to shape how his leadership is understood over time.
What Happens Next in Pope Leo XIV’s Papacy?
The immediate confirmed development is his planned surgery to remove the lung nodule, with recovery expected to take approximately a week. Further details about the nodule have not been made public, so readers should avoid drawing conclusions about his diagnosis or prognosis.
His planned November pastoral visit to South America is another upcoming event to watch for official updates. The Vatican may issue further information about his schedule depending on his recovery.
Beyond those immediate developments, Leo XIV will continue leading the Catholic Church through Vatican governance, pastoral teaching, appointments, and international engagements. His long experience in Peru and the Augustinian order will remain important context for understanding his public ministry, while his actual priorities should be judged through his official words and actions.
