A worldwide council of Catholic bishops, held in Rome from 1962 to 1965, that updated the Church's worship and its stance toward the modern world.
See it on the World Religions map →What it is
Pope John XXIII surprised the Church by calling it in 1959, seeking aggiornamento, Italian for 'updating'. About 2,500 bishops met in St. Peter's Basilica over four autumn sessions, with Protestant and Orthodox observers present. Under Paul VI it issued 16 documents: on the liturgy, allowing Mass in local languages; on the Church as the 'people of God'; on Scripture; on religious freedom; and on relations with other Christians and other religions.
Why it matters
It was the biggest Catholic shake-up in four centuries, reshaping parish life for today's roughly 1.4 billion Catholics and opening dialogue with other churches and faiths.
Sources and history
The council's 16 published documents, the official record of its debates (Acta Synodalia), bishops' diaries, and reporting by journalists who followed every session.
Questions and debates
Catholics still argue whether the council broke with the past or continued tradition, a debate Pope Benedict XVI framed in 2005 as 'rupture' versus 'reform'.

Connections (8)
▸Second Vatican Council ended with lifting the 1054 excommunications of the Great Schism between East and WestHistorical record
The connection
The council invited Orthodox observers, and its decree on ecumenism praised the Eastern churches. Pope Paul VI met Ecumenical Patriarch Athenagoras I in Jerusalem in 1964, the first such meeting in five centuries. On December 7, 1965, a joint declaration removed the 1054 excommunications 'from memory', though full communion was not restored.
When and where
Rome and Istanbul, December 7, 1965, read simultaneously the day before the council closed; Pope Paul VI and Patriarch Athenagoras I.
Historical evidence
The text of the 1965 Catholic–Orthodox joint declaration, and records and photographs of the 1964 Jerusalem meeting.
Questions and debates
Whether reunion is achievable remains open; papal authority and the filioque clause are still unresolved in joint theological talks running since 1980.
▸The Holocaust spurred Catholic rethinking at Second Vatican CouncilMostly agreed by scholars
The connection
After the Holocaust, Catholics confronted centuries of teaching that blamed Jews collectively for Jesus's death. French Jewish historian Jules Isaac, whose wife and daughter were killed at Auschwitz, urged Pope John XXIII in 1960 to change course. The council's Nostra Aetate (1965) rejected that blame and condemned antisemitism.
When and where
Vatican, Isaac's audience with John XXIII, June 1960; drafted under Cardinal Augustin Bea; approved October 28, 1965.
How do we know?
The text of Nostra Aetate, council records, Isaac's own account, and later documents such as the Vatican's 'We Remember: A Reflection on the Shoah' (1998).
Questions and debates
The document never names the Holocaust; debate continues over Pius XII's wartime record, with Vatican archives opened to researchers in 2020.
▸Second Vatican Council modernized Roman Catholic Church and the papacyHistorical record
The connection
The council reshaped everyday Catholic life: Mass in local languages with the priest facing the people, larger roles for laypeople, acceptance of religious freedom, and openness to other Christians and the modern world, while keeping core doctrine. Bishops were to share responsibility with the pope, a principle called collegiality.
When and where
St. Peter's Basilica, four sessions in the autumns of 1962–1965; Popes John XXIII and Paul VI; the revised Mass took effect in 1969–70.
Historical evidence
The 16 council documents, the 1970 Roman Missal, and decades of surveys of Catholic practice.
Questions and debates
Whether the council caused the Western drop in Mass attendance and priestly vocations, or simply coincided with the 1960s, is debated; traditionalist groups rejected parts of it.
▸Second Vatican Council was held at Vatican and St. Peter's BasilicaHistorical record
The connection
Pope John XXIII called the Second Vatican Council, which met in St. Peter's Basilica in four autumn sessions. More than 2,000 bishops from every continent sat in tiered seats lining the nave, with Protestant and Orthodox observers present. The setting signaled both the papacy's central authority and a newly global church.
When and where
St. Peter's Basilica, Vatican City, 1962–1965; Popes John XXIII and Paul VI.
Historical evidence
Official council records, photographs and films of the sessions, and journalists' daily reports.
Questions and debates
Little is uncertain about the venue; Catholics still debate whether the council's documents mark continuity with the past or a break.
▸Second Vatican Council opened the Church to Interfaith dialogueHistorical record
The connection
Nostra Aetate (1965), the council's shortest document, said the Church 'rejects nothing that is true and holy' in other religions. It praised Hindu and Buddhist spiritual practice, expressed 'esteem' for Muslims, and rejected blaming Jews for Jesus's death. In 1964 the Vatican created an office for relations with other religions.
When and where
Rome, 1964–65; Pope Paul VI and Cardinal Augustin Bea; the Secretariat for Non-Christians, now the Dicastery for Interreligious Dialogue.
Historical evidence
The text of Nostra Aetate, Vatican office records, and later events such as the 1986 Assisi meeting that built on it.
Questions and debates
How to balance dialogue with the Church's belief that salvation comes through Christ remains debated, as shown by the Vatican's 2000 document 'Dominus Iesus'.
▸Pope John Paul II carried forward Second Vatican CouncilHistorical record
The connection
As a young bishop, Wojtyła attended all four sessions and helped draft the document on the Church in the modern world. As pope he called the council his compass, issuing a new Code of Canon Law (1983) and Catechism (1992) to implement it and expanding outreach to other faiths. Critics said he reined in its reforms.
When and where
Rome, 1962–65, with Wojtyła present; papacy 1978–2005; Rome synagogue and Assisi gatherings, both 1986.
Historical evidence
Council records of his speeches, his encyclicals, the 1983 Code of Canon Law and the 1992 Catechism.
Questions and debates
Whether he faithfully carried out the council or restrained it is a central dispute between progressive and conservative Catholics.
▸Pope Francis renewed the spirit of Second Vatican CouncilMostly agreed by scholars
The connection
Francis, the first pope ordained a priest after the council, saw his task as completing it. He promoted 'synodality' (bishops and laypeople deciding together), giving women a vote at the 2023–24 synod; restricted the old Latin Mass in 2021; and declared council popes John XXIII and Paul VI saints.
When and where
Rome, 2013–2025; 'Traditionis Custodes', July 2021; the Synod on Synodality, 2021–2024; canonizations in 2014 and 2018.
How do we know?
His documents and speeches, which repeatedly call the council's reforms irreversible, and the synod's published records.
Questions and debates
Whether he fulfilled or departed from the council is debated; traditionalists accused him of confusion, and Leo XIV's direction is still taking shape.
▸Liberation theology drew energy from Second Vatican CouncilHistorical record
The connection
Vatican II urged the Church to read 'the signs of the times' and stand with the poor. Latin American bishops applied this at Medellín in 1968, denouncing 'institutionalized violence' and pledging themselves to the poor. Gutiérrez, an adviser there, published his founding book three years later.
When and where
Medellín, Colombia, 1968; Lima, 1971; the Puebla conference in Mexico, 1979; base communities in Brazil and Central America.
Historical evidence
The Medellín documents, Gutiérrez's book and its references to the council, and the Vatican's 1984 and 1986 responses.
Questions and debates
Whether liberation theology faithfully applied the council or overreached into Marxism divided John Paul II's Vatican; Francis's papacy softened the conflict.
