Catholic Beliefs FAQ

Yes. Catholics are Christians. Christianity encompasses all who believe in Jesus Christ as Lord and Savior, and the Catholic Church is the oldest and largest Christian community in the world, with over 1.3 billion members. Catholics hold all core Christian beliefs: that Jesus Christ is the Son of God, fully human and fully divine; that he died and rose from the dead; and that salvation comes through him. The Catholic Church traces its origins to the Apostles, with Peter as the first bishop of Rome.

"Christian" is the broader term encompassing all who follow Jesus Christ — including Catholics, Orthodox Christians, and the thousands of Protestant denominations. "Catholic" refers specifically to members of the Catholic Church in communion with the Pope in Rome. All Catholics are Christians, but not all Christians are Catholic. The major distinctions between Catholic and Protestant Christianity include the role of Scripture and Tradition, the sacramental system, the authority of the Pope, and the veneration of Mary and the saints.

Catholics believe in the Holy Trinity (one God in three Persons: Father, Son, and Holy Spirit), the Incarnation (God becoming human in Jesus Christ), the death and Resurrection of Jesus as the means of salvation, and the Church as the Body of Christ. Catholics hold that Scripture and Sacred Tradition together form one source of divine Revelation, interpreted by the Church's Magisterium. They also believe in the seven sacraments, the Real Presence of Christ in the Eucharist, the Communion of Saints, purgatory, and the resurrection of the dead.

A person becomes Catholic through Baptism — either as an infant raised in the faith, or as an adult through the Order of Christian Initiation of Adults (OCIA, formerly RCIA). Being Catholic involves believing what the Church teaches (the Creed), participating in the sacraments (especially Eucharist and Reconciliation), and living in communion with the Church under the authority of the Pope and bishops. Catholics are called to ongoing conversion, prayer, and service.

Yes. Catholics believe that Jesus Christ is fully God and fully human — the Second Person of the Holy Trinity who took on human nature in the Incarnation. This belief, known as the hypostatic union, was defined at the Council of Chalcedon (451 AD). Catholics profess this each week in the Nicene Creed: Jesus is "God from God, Light from Light, true God from true God, begotten not made, consubstantial with the Father." This is the foundational Christian confession shared across most Christian traditions.

The key differences include: (1) Authority — Catholics hold that Scripture, Tradition, and the Magisterium work together; most Protestants hold Scripture alone (sola scriptura). (2) Salvation — Catholics teach that salvation involves faith and works cooperating with grace; most Protestants emphasize faith alone (sola fide). (3) Sacraments — Catholics recognize seven sacraments as means of grace; most Protestants observe two (Baptism and Communion) as ordinances. (4) Mary and Saints — Catholics venerate Mary and ask saints for intercession; most Protestants do not.

The Catechism of the Catholic Church (CCC) is the official summary of Catholic teaching, published in 1992 under Pope John Paul II. It covers four pillars: the Creed (what Catholics believe), the Sacraments (how Catholics worship), the Commandments (how Catholics live), and the Lord's Prayer (how Catholics pray). It is the authoritative reference for Catholic doctrine and has been translated into dozens of languages.
