What are the four Marian dogmas of the Catholic Church?

The four dogmas

A dogma is a truth of divine revelation, solemnly defined by the Catholic Church, that the faithful are obligated to believe. The four Marian dogmas are the four truths about the Blessed Virgin Mary that have been so defined.

1. Mary, Mother of God (Theotokos)

• Defined at: the Council of Ephesus, 431, against the heresy of Nestorius.
• The teaching: Mary is rightly called the Mother of God, because the one whom she bore is one Person, who is fully God and fully man. To deny Mary the title "Mother of God" is to imply that there are two persons in Christ (one human, one divine) rather than one Person with two natures.

The Council of Ephesus, presided over by Saint Cyril of Alexandria, defined the Greek title Theotokos (literally "God-bearer") in opposition to Nestorius, who had proposed the lesser title Christotokos ("Christ-bearer"). The dogmatic definition was confirmed by the Formula of Union of 433 and reaffirmed at the Council of Chalcedon in 451.¹

The Solemnity of Mary, Mother of God, is celebrated on January 1, the eighth day of the Octave of Christmas.

2. Perpetual Virginity

• Affirmed at: the Lateran Synod of 649 (under Pope Saint Martin I).
• The teaching: Mary is "Ever-Virgin" (Aeiparthenos): she was a virgin before the conception of Christ, in the conception itself, and remained a virgin throughout her life.

The doctrine is found in the apostolic tradition from the second century onward, in the Protoevangelium of James and in the writings of the Fathers (Saint Athanasius, Saint Jerome, and others). The Lateran Synod of 649 expressed the teaching in three terms: Mary's virginity ante partum (before giving birth), in partu (in the act of giving birth), and post partum (after giving birth).²

Brothers and sisters of Christ mentioned in the New Testament (e.g., Matthew 13:55) are understood by the Catholic tradition either as cousins (the Aramaic and Hebrew terms used were broader than the modern English "brother") or as children of Joseph from a previous marriage (the older Eastern tradition, found in the Protoevangelium of James).

3. Immaculate Conception

• Defined by: Pope Pius IX in Ineffabilis Deus, December 8, 1854.
• The teaching: Mary was preserved from original sin from the first moment of her conception, by a singular grace of God in view of the merits of Jesus Christ.

4. Assumption

• Defined by: Pope Pius XII in Munificentissimus Deus, November 1, 1950.
• The teaching: Mary, at the end of her earthly life, was assumed body and soul into heavenly glory.

The chronological pattern

The two earliest Marian dogmas (Mother of God, Perpetual Virginity) were defined in the patristic and early medieval period as direct responses to christological heresies (Nestorianism and Monothelitism / various christological doubts). The two later dogmas (Immaculate Conception, Assumption) were defined in the modern era and represent the explicit dogmatization of doctrines long held in the universal liturgical and devotional tradition of the Church.

What is not (yet) a dogma

A fifth Marian doctrine, sometimes proposed for solemn definition, is the title Mediatrix of all graces and Co-Redemptrix. This title is taught in many magisterial documents (especially of Pope Saint John Paul II) as a doctrine of the Catholic faith, but it has not been solemnly defined as a fifth dogma; it is a teaching held with theological certainty without having received the formal ex cathedra definition.
