Updated July 23, 2026
What Roman Catholic believe
Roman Catholics believe that the Church founded by Jesus Christ subsists in the Roman Catholic Church, governed by the Pope as the successor of Saint Peter. Catholic doctrine holds that divine revelation comes through both Scripture and Sacred Tradition, interpreted by the Church's living Magisterium. The Church teaches that salvation is a process of justification involving faith, grace, and cooperative human works, not by faith alone. The seven sacraments, especially the Eucharist, are the primary means by which grace is conferred to the faithful.
Catholic worship centers on the Mass, in which the bread and wine are believed to become the actual body and blood of Christ through transubstantiation. The Church venerates Mary and the saints as intercessors and models of holiness, while affirming that worship belongs to God alone. Catholics maintain a robust body of social teaching covering ethics, human dignity, and the common good.
With more than one billion members, the Roman Catholic Church is the largest Christian body in the world. Its structure is hierarchical, with the Pope at the apex, followed by cardinals, bishops, and priests, and it maintains a consistent body of doctrine codified in the Catechism of the Catholic Church.
Key beliefs
- The Pope, as Bishop of Rome and successor of Peter, holds supreme pastoral authority over the universal Church.
- Divine revelation is transmitted through both Sacred Scripture and Sacred Tradition, interpreted by the Magisterium.
- Seven sacraments, instituted by Christ, confer sanctifying grace: baptism, confirmation, Eucharist, reconciliation, anointing of the sick, holy orders, and matrimony.
- The Eucharist is the real presence of Christ under the appearances of bread and wine, a doctrine called transubstantiation.
- Salvation is an ongoing process of justification that requires faith, grace, and cooperation with that grace through works of love.
- Mary is the Mother of God, preserved from original sin (the Immaculate Conception), and assumed body and soul into heaven.
- Purgatory is a state of purification that the faithful undergo before entering the fullness of heaven.
History
The Roman Catholic Church traces its origins to the apostolic community gathered around Jesus and, in particular, to the ministry of the apostle Peter, whom Catholics regard as the first Bishop of Rome. Over the first centuries the Church developed its hierarchical structure, creedal formulations, and sacramental practice through councils such as Nicaea (325), Constantinople (381), and Chalcedon (451). The Bishop of Rome gradually asserted a primacy of jurisdiction over the wider Church, a claim that contributed to the Great Schism with the Eastern churches in 1054.
The Protestant Reformation of the sixteenth century challenged papal authority, indulgences, and several Catholic doctrines, prompting the Council of Trent (1545-1563) to define and defend Catholic teaching in what is called the Counter-Reformation. The First Vatican Council (1869-1870) declared papal infallibility, and the Second Vatican Council (1962-1965) modernized liturgy, ecumenical relations, and the Church's engagement with the modern world. The contemporary Church continues to address questions of authority, sexual abuse scandals, and interfaith dialogue under the leadership of Pope Francis.
What makes Roman Catholic distinct
- Papal authority and apostolic succession give the Pope a unique teaching and governing role among all Christian leaders.
- Transubstantiation in the Eucharist and the sacrificial nature of the Mass distinguish Catholic sacramental theology from most Protestant views.
- The communion of saints, including prayerful veneration of Mary and the saints, is a defining devotional practice.
- Purgatory and the treasury of merits are doctrines not shared by Protestant or Orthodox traditions in the same form.
- A centralized, worldwide hierarchy with a unified body of canon law provides doctrinal and disciplinary consistency across the globe.

Frequently asked questions
- What is the difference between Catholic and Christian?
- All Catholics are Christian, but not all Christians are Catholic. "Catholic" refers specifically to Christians in communion with the Bishop of Rome, the Pope, who accept the authority of the Magisterium and the seven sacraments. Protestant and Orthodox Christians share core beliefs about Jesus but reject papal authority and hold different views on sacraments and tradition.
- Do Catholics worship Mary and the saints?
- Catholics do not worship Mary or the saints, because worship belongs to God alone. They venerate them, which means honoring them as models and asking for their intercessory prayers, much as one might ask a fellow believer to pray for them. The distinction between latria (worship due to God) and dulia (honor due to saints) is a long-standing Catholic theological principle.
- What is transubstantiation?
- Transubstantiation is the Catholic doctrine that, during the Mass, the substance of the bread and wine changes entirely into the body and blood of Christ, even though the appearances (taste, texture, color) remain unchanged. Catholics believe this occurs through the words of consecration spoken by an ordained priest. The Eucharist is therefore treated with the reverence due to Christ himself.
- Why do Catholics confess sins to a priest?
- Catholics believe that Jesus gave his apostles the authority to forgive sins (John 20:23), and that this authority is passed down through ordination. The priest acts in the person of Christ when he absolves the penitent. Confession also provides spiritual counsel and accountability, and it is tied to the sacrament of reconciliation as a means of receiving grace.
- Do Catholics believe the Bible is the only authority?
- No. Catholics hold that divine revelation is transmitted through both Scripture and Sacred Tradition, and that both are interpreted by the Church teaching office, the Magisterium. This contrasts with the Protestant principle of sola scriptura, which treats Scripture as the only infallible authority for faith and practice.
- What is purgatory?
- Purgatory is the Catholic teaching that those who die in friendship with God but are still imperfectly purified undergo a final purification before entering heaven. It is not a second chance for the unrepentant, and it is not hell. Catholics base the doctrine on passages such as 2 Maccabees 12:46 and 1 Corinthians 3:15, and they pray for the souls undergoing this purification.
- What is the difference between Roman Catholic and Eastern Orthodox?
- Both traditions share apostolic succession, seven sacraments, and a sacramental worldview, but they divided in the Great Schism of 1054 over the authority of the Pope and the wording of the Nicene Creed (the filioque clause). Orthodox churches are self-governing and do not recognize papal supremacy. They also differ on purgatory, the Immaculate Conception, and the date of Easter in some cases.
