Ever Virgin (Aeiparthenos): the perpetual virginity of Mary

“I believe in one Lord, Jesus Christ… who for us men and for our salvation descended from heaven and was incarnate of the Holy Spirit in the Virgin Mary.” (Nicene-Constantinopolitan Creed)

I. The Virgin shall conceive: The oracle of Isaiah that spanned the centuries

Chapter seven of the book of Isaiah contains one of the most commented texts in Scripture. Before King Ahaz of Judah, threatened by the hostile alliances of Aram and Israel, the prophet announces a divine sign: “Behold, a virgin shall conceive and bear a son, and shall call his name Emmanuel” (Isaiah 7:14). The Hebrew word almah, translated by the Septuagint as parthenos (virgin), opened an hermeneutical path that Christian tradition recognized as decisive. The Gospel of Matthew, narrating the Annunciation to Joseph, explicitly quotes this Isaiah text: “All this took place to fulfill what the Lord had announced through the prophet: Behold, a virgin shall conceive” (Matthew 1:22-23). Mary’s virginity is not, therefore, a secondary biographical detail; it is the fulfillment of a prophetic promise, the sign that distinguishes the Incarnation from any other human generation, and the proof that the entry of the Eternal Word into history was not the result of human initiative but of God’s exclusive initiative. This virginity, which ancient Christian tradition began to contemplate in its three temporal dimensions (before, during, and after childbirth), became one of the axes of dogmatic mariology.

II. Aeiparthenos: The definition of perpetual virginity

The Greek term Aeiparthenos, “Always Virgin,” appears in Christian theological writings from the fourth century and was used by Athanasius of Alexandria, Epiphanius of Salamis, John Chrysostom, and Cyril of Alexandria. The most explicit dogmatic formulation is found in the Second Council of Constantinople in 553 and was reaffirmed with particular precision at the Council of Latran in 649, under Pope Martin I. This latter council explicitly defined the triple virginity of Mary: “If anyone does not confess, according to the Holy Fathers, that Saint Mary is always Virgin and Immaculate Mother of God… that she conceived properly and truly, without seed, from the Holy Spirit, the Word itself… and generated him incorruptibly, preserving her virginity indissoluble even after childbirth, let him be excommunicated” (Latrán, Canon 3). This definition is not a speculative theological abstraction; it is the confession that Mary’s virginity belongs to the integrity of the Incarnation mystery. Denying perpetual virginity is not just modifying an accessory Marian doctrine; it alters how one understands God’s entry into human flesh.

III. Joseph and the respected virginity: The Matthew account of the Annunciation

The Gospel of Matthew presents the Annunciation to Joseph with a sobriety that contrasts with Luke’s account of the Annunciation to Mary. “Mary, his wife, was betrothed to Joseph. But before they came together, she conceived by the Holy Spirit. Joseph, her husband, being a just man and unwilling to put her to shame, resolved to divorce her quietly. As he considered these things, behold, an angel of the Lord appeared to him in a dream, saying: ‘Joseph, son of David, do not fear to take Mary as your wife, because that which is conceived in her is from the Holy Spirit.’ She will give birth to a son, and you shall call his name Jesus” (Matthew 1:18-21). This text contains an implicit theology of Mary’s virginity that the entire patristic tradition developed. Joseph accepts Mary’s virginity as a revelation from an angel, and his justice consists precisely in respecting it. The marital life between Mary and Joseph exists, but in form of spiritual and legal communion, not sexual. The “brothers of Jesus” mentioned in the Gospels are, according to ancient Christian interpretation, extended family relatives, close cousins, or brothers-in-law, not children from the same womb. This interpretation was vigorously defended by Jerome in the fourth century against Helvidius, who had argued the contrary, and the universal Church embraced as firm doctrine that Mary’s virginity remained before and after Jesus’ birth.

IV. The theology of perpetual virginity: A sign of total dedication to God

The doctrine of Mary’s perpetual virginity, which at first glance may seem an extrinsic biographical detail for Christian faith, reveals deep symbolic and existential density to theological reflection. Mary’s virginity is a sign of her total dedication to God: her body, her heart, her entire life belonged exclusively to the Holy Spirit. There was no prior sanctification of Mary’s life before grace; grace preceded and configured her whole existence. Virginity expresses this radical totality. And it is precisely because she is totally God’s that Mary can be totally for humanity. Virginity is not egoism; it is the opposite: it is the complete opening that makes possible a spiritual motherhood without boundaries. The Second Vatican Council, recalling that “Mary consecrated herself totally to the person and work of her Son” (Lumen Gentium), articulates this logic of virginity as service. Aeiparthenos is not distance from humanity, but radical nearness: Mary is spiritual mother to all precisely because she was not biological mother to anyone else. Perpetual virginity is, in this sense, the theological condition for universal motherhood, and Christian tradition rightly confessed it with the same firmness with which it confesses the Incarnation that it protects and reveals.
