What Are Dogmas?
In Catholic teaching, dogmas are not theological opinions, nor “ordinary teachings” to which the faithful are called to give “religious assent” of mind and will (CCC 892). They are truths revealed by God and definitively taught by the Church as binding on all the Catholic faithful. When the Church defines a dogma, it draws a clear line: this is part of the deposit of faith and cannot be denied without rejecting something essential to Christianity itself (CCC 84, 86, 88; see also Jimmy Akin’s related article).
The Marian dogmas fall into this category. They are not exaggerations about Mary or later doctrinal inventions, but precise teachings that illumine and protect core doctrines—especially about who Jesus Christ is, as well as the exalted status given to and received by his earthly mother. To understand these dogmas is to see how the Church safeguards the truth about the Incarnation and the work of Christ’s redemption in our souls, including through the intercession of Mary as our spiritual mother (Rev. 12:17).
What Are the Marian Dogmas?
The Catholic Church recognizes four solemn Marian dogmas:
- Mary as Mother of God (Theotokos). Mary is truly the mother of Jesus Christ, who is both God and man; this title safeguards the doctrine of the Incarnation and was defined at the Council of Ephesus (431). (Mary, Mother of God)
- Mary’s Perpetual Virginity. Mary remained a virgin before, during, and after the birth of Christ; this teaching was held by the ancient Church and consistently affirmed in Catholic Tradition. (How to Explain the Perpetual Virginity of Mary)
- The Immaculate Conception. From the first instant of her conception, the Father preserved Mary from original sin in view of the merits of her Son Jesus Christ; this dogma was defined by Pope Pius IX on December 8, 1854. (Immaculate Conception and Assumption)
- The Assumption. At the end of her earthly life, Mary was assumed body and soul into heavenly glory; this dogma was defined by Pope Pius XII on November 1, 1950. (The Assumption of Mary in History)
Notes on scope and status: These four teachings are the formally defined Marian dogmas of the Catholic Church. Other Marian doctrines and devotional titles exist in magisterial teaching and theological tradition, but they are not defined as dogmas. (Why Mary Matters)
These four Marian dogmas form the foundation of what the Church definitively teaches about Mary. They are not isolated claims, but part of a coherent vision of salvation centered on our Lord and how he became to man to redeem us. While many other Marian teachings and devotions have developed over time, these four stand apart in their authority and clarity. Taken together, they show that honoring Mary is not a distraction from the gospel. Rather, it is a way of safeguarding and proclaiming it.
