Question 26 · Jesus Christ

May Mary be called Mother of God?

What the sources show

Ignatius of Antioch c. 110 · Gregory of Nazianzus c. 382Mother of God

The title protects a claim about Christ, not only about Mary: the one she bore is God. Ignatius already says "our God" was carried in her womb, and Gregory of Nazianzus, fifty years before Ephesus, made the title a test of faith. ¹³

Anastasius, Nestorius's chaplain (as Socrates reports) c. 428 · Nestorius (as quoted by Cyril) c. 429Mother of Christ

At Constantinople in 428 Nestorius's chaplain preached that no one should call Mary Mother of God. Nestorius argued that Scripture says "Christ", not "God", when it speaks of the birth. ⁴⁵

Council of Ephesus c. 431 · Council of Chalcedon c. 451 · Socrates Scholasticus c. 440Mother of God

The Council of Ephesus (431) affirmed the title, and Chalcedon repeated it. The historian Socrates noted that older writers, Origen among them, had already used it. ⁶⁷⁹

Ignatius of Antioch d. c. 110 ADLetter to the Ephesians 18.2

For our God, Jesus the Christ, was carried in the womb by Mary, by God's plan, of the seed of David and of the Holy Spirit. He was born and was baptized, so that by his suffering he might cleanse the water.

Ignatius does not use the title, but he says "our God" was carried in Mary's womb, which is what the title means.

Mother of God

Alexander of Alexandria d. 328 ADLetter to Alexander of Thessalonica, in Theodoret, Church History 1.4

Our Lord Jesus Christ, who truly, and not in appearance, bore a body from Mary the Mother of God, and came among the race of men at the consummation of the ages to abolish sin.

Alexander writes against Arius (about 324), a century before Ephesus: an Alexandrian bishop already calls Mary Theotokos, Mother of God, in passing, as a matter of course. The letter survives because Theodoret quotes it whole in his Church History.

Mother of God

Gregory of Nazianzus c. 329/330–390 ADLetter 101, to Cledonius 101.16

If anyone does not accept holy Mary as Mother of God, he is cut off from the Godhead. If anyone says that Christ passed through the Virgin as through a pipe, and was not formed in her both divinely and humanly (divinely, because without a man; humanly, because by the law of pregnancy), he is equally godless.

Fifty years before Ephesus. For Gregory the title protects the truth that the one born of Mary is God.

Mother of Christ

Nestorius (as quoted by Cyril) c. 386–c. 451 ADQuoted in Cyril of Alexandria, Dialogue against Nestorius opening

When the divine Scripture speaks of Christ's birth from Mary the Virgin, or his death, it nowhere appears to say "God", but "Christ" or "Lord" or "Jesus", since these three names signify the two natures, sometimes this one, sometimes that.

Nestorius preferred "Mother of Christ". His opponent preserves his words; Nestorius himself said he would accept "Mother of God" if rightly explained.

And Origen too, in the first volume of his commentary on the apostle's Letter to the Romans, examined at length how she is called Mother of God. So Nestorius seems to have been unaware of the works of the ancients.

A historian's report that Origen, about 246, already discussed the title. The Greek of Origen's commentary is lost and Rufinus's Latin does not keep the passage, so this cannot be checked.

Mother of God

Hesychius of Jerusalem fl. c. 412–450 ADHomily on Mary the Mother of God opening

"Therefore the one to be born will be called holy, the Son of God" (Luke 1:35). Do you see how great the dignity of the virgin Mother of God is? For the only-begotten Son of God, the maker of the world, was carried by her as an infant.

A Jerusalem preacher of the same years, using the title as a matter of course.

How this page was made

Every early quote was read in its Greek or Latin and translated for this page by Claude (Opus 5.5) on 13 October 2026. Each line names the printed edition it was read from. A quote marked indirect does not state the answer outright; read its note. A writer's silence is never counted as an answer.
