What is Catholic Doctrine - Tommy - 08-07-2026
WHAT IS CATHOLIC "DOCTRINE"?
Catholic doctrine is the complete body of official and authoritative teachings of the Catholic Church on faith and morals. It comes from Sacred Scripture and Sacred Tradition, and it is interpreted by the Pope and bishops (Magisterium). These teachings cover core beliefs about God, Jesus, the sacraments, and how to live a moral life.
Thus, doctrine concerns both:
- Faith: what Catholics are called to believe - for example, that God is Trinity and that Jesus Christ is truly God and truly man.
- Morals: how Catholics are called to live - for example, that human life must be respected and that we must love God and neighbor.
Core Sources of Teaching
- Sacred Scripture: The 73 books of the Catholic Bible.
- Sacred Tradition: The living passing down of Jesus's teachings from the time of the Apostles.
- The Magisterium: The official teaching authority of the Pope and bishops in union with him.
The Church does not invent a new revelation. When she defines a doctrine, she clarifies and solemnly proposes a truth already contained in the deposit of faith.
Also note that the Catechism of the Catholic Church (CCC) outlines and further details Catholic doctrine (faith and morals). The CCC is an "official book" of the Catholic Church containing doctrine, though it is not dogmatic.
Examples of Main Catholic Doctrines
- The Trinity: Belief in one God in three persons: Father, Son, and Holy Spirit.
- Jesus Christ: Belief that Jesus is the Son of God, who died and rose to save humanity from sin.
- The Sacraments: Seven sacred rituals—including Baptism, Eucharist, and Reconciliation—that give God's grace.
- The Communion of Saints: Belief in a spiritual connection between believers on earth, in purgatory, and in heaven, including the honor given to Mary, the Mother of God.
Doctrine vs. Dogma
- Doctrine: A broad term representing all official Church teachings on faith and morals.
- Dogma: A specific core part of doctrine revealed directly by God and formally defined by the Church as binding for all believers to accept.
Major teachings of the Catholic Church discussed in the early councils of the Church are summarized in various creeds, especially the Nicene (Nicene-Constantinopolitan) Creed and the Apostles' Creed. Since the 16th century the Church has produced catechisms which summarize its teachings; in 1992, the Catholic Church published the official Catechism of the Catholic Church (CCC).
The Catholic Church understands the living tradition of the Church to contain its doctrine on faith and morals and to be protected from error, at times through infallibly defined teaching. The Church believes in revelation guided by the Holy Spirit through sacred scripture, developed in sacred tradition and entirely rooted in the original deposit of faith. This developed deposit of faith is protected by the "magisterium" or College of Bishops at ecumenical councils overseen by the pope, beginning with the Council of Jerusalem (c. AD 50).
CATHOLIC THEOLOGY AND DOCTRINE:
Catholic theology is the understanding of Catholic doctrine or teachings, and results from the studies of theologians. It is based on canonical scripture, and sacred tradition, as interpreted authoritatively by the magisterium of the Catholic Church.
Catholic theology contains a highly developed set of doctrines that have matured over two millennia, from the foundational contributions of the Apostles to the Church Fathers to the Medieval Scholastics to the Modern era. Fundamental areas of Catholic theology include the nature of God, Jesus Christ, humanity, the saints, and the Virgin Mary; divine grace and its role in justification and salvation; and other topics such as Biblical theology, moral theology, spiritual theology, sacramental theology, ecclesiology, and eschatology. These topics have often been developed in contrast to various Christian heresies or other traditions of Christianity.
