Pope Leo XIV, the newly elected pontiff, made headlines on Thursday, May 8, as he took on his papal name following the centuries-old tradition of choosing a new name upon ascending to the papacy. This tradition dates back to the very first pope, St. Peter, whose original name was Simon. By selecting the name Leo XIV, the pontiff, formerly known as Robert Francis Prevost, is making a deliberate nod to history and tradition.


The legacy of the name Leo in the papacy is steeped in rich history, with the first Pope Leo I elected in the year 440. Known for his efforts to unify the Church during a time of turmoil, Pope Leo I set a precedent for future pontiffs who adopted the name. Notably, Pope Leo XIII, who served from 1878 to 1903, was revered for his advocacy for the marginalized and his contributions to Catholic social teaching.
According to experts in Catholic studies, Pope Leo XIV’s choice of name signifies a commitment to prioritising moral leadership and ethical values during his papacy. Dr. Charles Gillespie, a professor at Sacred Heart University, describes the selection of the name Leo as a signal that the new pope aims to continue the legacy of championing the underprivileged and promoting social justice within the Church and globally.
In his first message following his election, Pope Leo XIV conveyed his dedication to upholding moral principles and advocating for the disadvantaged. Drawing parallels to the legacy of Pope Leo XIII, who was instrumental in shaping Catholic social teachings through his encyclical “Rerum novarum,” the new pontiff is poised to carry forward a tradition of compassionate leadership within the Church.
Dr. William T. Cavanaugh, a professor at DePaul University, notes that the choice of the name Leo may also indicate a willingness to engage with diverse intellectual currents, particularly in relation to Catholic social teachings. By aligning himself with the legacy of Pope Leo XIII’s endorsement of the work of Thomas Aquinas, a prominent theologian, Pope Leo XIV showcases a commitment to intellectual dialogue and openness.
The selection of a papal name is a symbolic act that reflects both continuity and innovation within the papacy. While some names have recurred throughout history, such as John, Gregory, Benedict, Pius, Clement, Innocent, Paul, and Leo, certain names like Peter, James, Andrew, Joseph, and Luke have remained unclaimed by any pope. The Vatican explains that popes often choose names to honour their predecessors or to signal a new direction for their papacy.
In his choice of the name Leo XIV, Pope Leo XIV marks a departure from his immediate predecessors, suggesting a fresh start and a renewed focus on key issues facing the Catholic Church and the global community. By embracing a name with a storied legacy, the first American pontiff underscores his commitment to upholding the values of compassion, justice, and ethical leadership in his papal tenure.
