When a new pontiff steps onto the balcony of St. The short answer is yes, the Pope almost always changes his name upon election. Peter’s Basilica and announces his regnal name, he participates in a tradition that stretches back over a millennium. While not strictly required by canon law, the adoption of a new name has become an expected and deeply symbolic act, signaling the beginning of a new ministry and often hinting at the spiritual direction the new Bishop of Rome intends to pursue.
Some disagree here. Fair enough It's one of those things that adds up..
The Historical Origins of the Papal Name Change
The practice was not always the norm. Practically speaking, for the first several centuries of the Church, popes generally retained their baptismal names. The first recorded instance of a Pope changing his name occurred in 533 AD. Consider this: a priest named Mercurius was elected to the See of Peter. Considering it inappropriate for the Vicar of Christ to bear the name of a pagan Roman god (Mercury), he chose the name John II, honoring his predecessor, Pope John I, who had died a martyr.
This set a precedent, though it did not become an immediate, unbreakable custom. Plus, it was not until the late 10th and 11th centuries that the practice solidified into a near-universal tradition. Also, the turning point is often attributed to Pope John XIV (983–984), born Pietro Canepanova. Day to day, he chose the name John to avoid being called "Pope Peter II," as there has long been a reluctance to use the name of the first Pope out of reverence for the Prince of the Apostles. Since the election of Pope Sergius IV in 1009, every single Pope has adopted a new name upon election That's the part that actually makes a difference..
Why Do Popes Change Their Names?
The decision to adopt a regnal name is layered with theological, historical, and personal significance. It serves several distinct purposes:
1. A Sign of a New Mission
In the Bible, a change of name often signifies a radical change in vocation or identity. Abram became Abraham ("father of a multitude"), Simon became Peter ("rock"), and Saul became Paul. By taking a new name, the Pope signals that he is no longer merely a private individual—Cardinal Jorge Bergoglio or Cardinal Joseph Ratzinger—but the universal pastor of the Catholic Church. He assumes a new identity rooted in the Petrine ministry.
2. Honoring a Predecessor or Saint
Most frequently, a Pope chooses the name of a previous Pope he admires or wishes to emulate. This creates a spiritual continuity.
- Pope John Paul I combined the names of his two immediate predecessors, John XXIII and Paul VI, to signal his desire to continue the reforms of the Second Vatican Council.
- Pope John Paul II kept the name to honor his short-lived predecessor.
- Pope Benedict XVI chose the name to honor Pope Benedict XV (a peacemaker during WWI) and St. Benedict of Nursia (the father of Western monasticism), signaling a focus on Europe’s Christian roots and liturgical tradition.
- Pope Francis broke a millennium of tradition by choosing the name Francis, honoring St. Francis of Assisi. This was the first time a Pope took the name of a non-pope saint since the 10th century, signaling a papacy focused on poverty, humility, and care for creation.
3. Signaling a Thematic Agenda
The name acts as a thesis statement for the pontificate. When Cardinal Albino Luciani became John Paul I, he immediately signaled a bridge between the "Good Pope John" and the "Pilgrim Pope Paul." When Cardinal Jorge Bergoglio became Francis, he instantly telegraphed a shift toward a "poor church for the poor" and ecological concern (Laudato Si') That's the part that actually makes a difference..
4. Avoiding the Name "Peter"
There is a long-standing, unwritten prohibition against taking the name Peter II. This stems from a combination of reverence for the first Pope and a medieval prophecy attributed to St. Malachy, which suggests "Peter the Roman" would be the final Pope. No Pope has ever dared to take the name Peter, viewing it as presumptuous or apocalyptically charged.
The Mechanics: When and How Does It Happen?
The name change occurs immediately upon acceptance of the election.
Inside the Sistine Chapel, after the ballots are counted and a two-thirds majority is reached, the Dean of the College of Cardinals approaches the Cardinal-elect. On the flip side, he asks the canonical question in Latin: "Acceptasne electionem de te canonice factam in Summum Pontificem? " ("Do you accept your canonical election as Supreme Pontiff?").
Once the Cardinal answers "Accepto" ("I accept"), he becomes Pope. "* ("By what name do you wish to be called?Also, the Dean then asks: *"Quo nomine vis vocari? ").
The new Pope announces his chosen name. The Master of Pontifical Liturgical Celebrations documents it immediately. The Cardinal Protodeacon then steps onto the central balcony (Loggia della Benedizione) and proclaims to the world: "Habemus Papam" ("We have a Pope"), announcing the new Pope's birth name followed by his chosen regnal name Simple as that..
From that moment forward, official documents, seals, coins, and correspondence bear only the regnal name. The birth name is effectively retired from public ecclesiastical use, though it remains the name on his baptismal certificate.
Notable Exceptions and Nuances
While the tradition is nearly absolute, history offers a few fascinating nuances:
The Last Pope to Keep His Birth Name
Pope Marcellus II (elected 1555), born Marcello Cervini degli Spannocchi, is the most recent Pope to retain his baptismal name (albeit in a Latinized form). Before him, Pope Adrian VI (1522), born Adriaan Florensz Boeyens, also kept his name. Since Marcellus II, 47 consecutive Popes have changed their names.
The "Double Name" Innovation
Pope John Paul I (1978) was the first Pope to choose a double name. He did so explicitly to honor the two men who had shaped the modern Church: John XXIII (who called the Council) and Paul VI (who implemented it). His successor, John Paul II, continued the double name, making it one of the most recognizable papal designations in history.
The First "Francis"
Pope Francis (2013) was the first Pope to take the name of St. Francis of Assisi. It was also the first new papal name (one not used by a previous Pope) since Pope Lando (913–914), a gap of over 1,100 years. This bold choice underscored his desire to chart a distinct course.
Retired Popes
When Pope Benedict XVI resigned in 2013, he did not revert to "Cardinal Ratzinger." He retained the name Benedict XVI and the title "Pope Emeritus" (or "Roman Pontiff Emeritus"). He continued to wear the white cassock (without the mozzetta and fascia) and kept his regnal name until his death in 2022. This established a new precedent for the status of a retired Bishop of Rome And it works..
The Symbolism of the Number
If a Pope chooses a name used previously, he adds a Roman numeral (e.Worth adding: g. , Benedict XVI, Pius XII). This places him in a dynastic line of sorts. The numbering follows the official list of Popes (the Annuario Pontificio), which occasionally leads to historical quirks.
To give you an idea, there is no Pope John XX. Due to a historical counting error involving an antipope and a misnumbered list in the Middle Ages, the numbering skipped from John XIX to John
The gap left by the missing John XX was eventually filled—though not as originally intended—by Pope John XXI (1276‑1277). Born Pedro Julião, the Portuguese cardinal had studied astronomy and, believing the papal register to be accurate, chose the name “John XX” in the expectation that it would honor his predecessors. When the College of Cardinals examined the official list, they discovered that no legitimate Pope John XX had ever existed. Rather than risk another schism, they accepted the new pontiff as John XXI, thereby preserving the continuity of the papal line while inadvertently perpetuating the medieval error.
The incident illustrates how a clerical miscount can echo through centuries, shaping the very nomenclature by which the papacy is remembered. Subsequent pontificates have occasionally revived the curiosity of missing numerals, though none have matched the medieval slip that erased John XX. And other notable gaps include Pius XIII, Gregory XVII, and Benedict XIV, none of which have been borne by a reigning pope, leaving those numbers as dormant placeholders in the Annuario Pontificio. The absence of these names reflects both a reverence for the sanctity of earlier pontiffs and a pragmatic desire to avoid confusion among the faithful.
Easier said than done, but still worth knowing.
In the modern era, the choice of a regnal name continues to serve as a deliberate statement of pastoral direction. Conversely, the double‑name tradition initiated by John Paul I and sustained by John Paul II demonstrated how a pontiff can weave together the legacies of two predecessors, creating a distinctive brand that resonates across continents. Pope Francis’ adoption of a name never before used since Lando (913‑914) signaled a break from institutional precedent, emphasizing humility and a focus on the marginalized. Even the act of retaining a birth name, as Marcellus II did in 1555, remains a rare but powerful assertion of personal continuity with one’s baptismal identity Nothing fancy..
Worth pausing on this one.
The practice of appending a numeral—whether to honor a predecessor, to correct a historical anomaly, or simply to maintain dynastic clarity—underscores the papacy’s unique blend of spiritual authority and institutional memory. Each name and number carries layers of meaning: theological, political, and cultural. As the College of Cardinals prepares to elect the next Bishop of Rome, they will once again weigh the weight of history against the needs of a contemporary Church, choosing a name that will define a papacy for generations to come And that's really what it comes down to..
In sum, the evolution of papal names—from the rare retention of a baptismal identity to the bold invention of a wholly new regnal title—reflects the papacy’s capacity to both preserve tradition and adapt to changing times. The quirks of numbering, the occasional gaps, and the symbolic resonance of each chosen name together compose a living chronicle of the Church’s self‑understanding. As the conclave deliberates, the world will once more listen for the words “Habemus Papam,” knowing that behind that announcement lies a rich tapestry of history, faith, and the ever‑present desire to lead the faithful toward a renewed vision of the Gospel.
