Pope John XXIII
Discover the life and legacy of Pope John XXIII (1881–1963), the “Good Pope” who convened the Second Vatican Council, championed ecumenism, modernized the Church, and left a lasting spiritual and institutional impact.
Introduction
Pope John XXIII (born Angelo Giuseppe Roncalli) served as the Bishop of Rome and head of the the Catholic Church from October 1958 until his death in June 1963.
Though many cardinals expected his short pontificate to be a transitional one, John XXIII surprised observers by opening the Second Vatican Council (Vatican II), shifting the Church toward a more pastoral, open, and dialogical stance with the modern world.
In this article, we will trace his early life, priestly and diplomatic career, papacy, teachings, and enduring influence.
Early Life and Family
Angelo Giuseppe Roncalli was born on November 25, 1881 in Sotto il Monte, a small village in the Bergamo province of Lombardy, Italy.
He was one of thirteen children born to Giovanni Battista Roncalli and Marianna Mazzola, who were sharecroppers.
As a youth, he displayed deep piety and intellectual promise. He entered seminary training, eventually being ordained a priest on August 10, 1904.
Priestly Ministry, Diplomatic Service & Pre-Papal Career
Early Ministry & War Service
After ordination, Roncalli served in pastoral roles and seminary teaching.
During World War I, he served as a military chaplain and stretcher-bearer in the medical corps.
Diplomatic & Pastoral Assignments
In 1925, Pope Pius XI appointed him Apostolic Visitor to Bulgaria and consecrated him as a bishop (titular archbishop of Areopolis).
Later, he was named Apostolic Delegate / Nuncio to Turkey and Greece (1934 onward), and then to France (from 1944).
During World War II and afterward, Roncalli used his diplomatic posts to assist Jewish refugees and persecuted peoples, issuing baptismal certificates (so-called “baptism of convenience”), distributing immigration documents, and working discreetly to protect lives.
In 1953 Pope Pius XII elevated him to Cardinal and appointed him Patriarch of Venice (while assigning him the title of Cardinal-Priest of Santa Prisca).
In Venice, he cultivated a pastoral style of leadership, known for humility, visiting parishes, and personal simplicity.
Papal Election & Pontificate
Election & Early Actions
Following the death of Pope Pius XII in October 1958, Roncalli entered the conclave and on October 28, 1958 was elected pope at age 76.
He chose the name John XXIII, a name not used in recent centuries and signaling a break with expectation.
Many expected a conservative, short-term “caretaker” pope, but John XXIII would defy those expectations.
Early in his papacy, he made symbolic gestures of outreach: visiting hospitals, prisons, and speaking informally — even setting aside the formal “we” pronoun often used by popes.
Major Themes & Initiatives
Second Vatican Council (Vatican II)
John XXIII’s signature act was convoking an ecumenical council to engage the Church with the modern world. Vatican II formally opened on October 11, 1962.
His opening address, Gaudet Mater Ecclesia, set a tone of renewal (aggiornamento) — bringing the Church up to date, while preserving its essence.
Though he died before the council’s completion, his vision guided many of its early reforms.
Pastoral Emphasis & Social Teaching
John XXIII reoriented the papal office toward pastoral care, encouraging the Church to listen and dialogue rather than only teach.
He issued the famous encyclical Pacem in Terris (1963) — a groundbreaking document addressing human rights, social justice, the common good, and peace in the nuclear age. It extended moral teaching not just to Catholics but to all people of goodwill.
He also sought to internationalize the College of Cardinals (appointing cardinals from Africa, Asia, Latin America) and expanded the number of cardinals beyond the traditional limit of 70.
In liturgical practice, he authorized modest reforms, such as adding the name of St. Joseph to the Roman Canon (Mass) — the first change in centuries.
He also sought improved relations with non-Catholic Christians and other religions (especially Judaism), intervened to remove offensive language from liturgical prayers toward Jews, and blessed a synagogue in Rome — gestures of reconciliation.
He engaged in diplomatic overtures toward communist nations (a kind of Ostpolitik), advocating dialogue rather than confrontation.
Final Months & Death
In September 1962, John XXIII was diagnosed with stomach cancer, though the Vatican did not officially disclose it for some time.
His health declined, and he continued working despite physical suffering. On June 3, 1963, he passed away in the Vatican.
He is buried in St. Peter’s Basilica (altar of St. Jerome).
Teachings & Quotes
John XXIII’s papacy is remembered as much for his style and tone as for formal documents. Here are some of his notable ideas and quotations:
“Consult not your fears but your hopes and your dreams. Think not about your frustrations, but about your unfulfilled potential.”
“We were all made in God’s image, and thus, we are all godly alike.”
“Freedom consists of being bold.”
In Pacem in Terris, he affirmed the rights to life, bodily integrity, and the material necessities (food, clothing, shelter, medical care) for all persons — framing them as human, not merely Christian, rights.
He insisted on humility in leadership: for example, he once remarked (jokingly) after being elected, that the cassocks prepared for the pope didn’t fit him, and he quipped about how he would look on television.
These expressions reflect his vision: a Church renewing itself, reaching out with charity and dialogue, and serving as a moral voice in a changing world.

Church Reform & Modernization
John XXIII is widely credited with initiating a new era in Catholicism. His emphasis on engagement, pastoral care, and openness shaped the reforms of Vatican II, which introduced major changes in liturgy (vernacular languages), ecclesiology (greater role for bishops and laity), interfaith relations, and Church self-understanding.
His concept of aggiornamento (“bringing up to date”) continues to influence debates about how the Catholic Church relates to science, culture, and social change.
In Christian unity, John XXIII is remembered as a bridge figure: his gestures toward Jews and other Christians laid groundwork for ecumenical and interreligious dialogue.
He also reshaped the global character of the Church by appointing cardinals from non-European countries and broadening participation in the Church’s leadership.
Popular Memory
John XXIII is affectionately nicknamed “Il Buon Papa” (“the Good Pope”) for his warmth, humility, and personal accessibility.
He remains one of the most beloved modern popes, admired across Catholic and non-Catholic circles.
Institutions around the world bear his name — schools, hospitals, foundations — in honor of his legacy.
