The virgin birth

The virgin birth — the claim that Jesus was conceived by the Holy Spirit without a human father — is one of the most theologically significant and historically contested claims in the New Testament. It appears in two of the four canonical Gospels: Matthew and Luke, both composed roughly 80–90 CE, several decades after the events they describe.¹ The other two Gospels say nothing about Jesus’s origins. Paul, whose letters predate all four Gospels, describes Jesus as “descended from David according to the flesh” (Romans 1:3, NRSV) without any reference to a miraculous conception. The Gospel of John, writing independently of the Synoptic tradition, calls Jesus the “son of Joseph” through the mouth of his own disciples (John 1:45, NRSV).¹³

This article examines what Matthew and Luke actually claim, the textual and translation history of the Isaiah prophecy on which the claim rests, the logical problem posed by two contradictory genealogies tracing Joseph’s bloodline, the silence of the earliest witnesses, and the well-documented ancient literary convention of attributing divine parentage to important figures. The purpose is encyclopedic: to present the claims, the textual evidence, and the scholarly analysis in plain terms.

What Matthew and Luke claim

The virgin birth is stated explicitly in both Matthew and Luke, though the two accounts approach it from different angles. Matthew’s narrative is told primarily from Joseph’s perspective. When Joseph discovers that Mary is pregnant before they have lived together, he resolves to dismiss her quietly. An angel then appears to him in a dream and explains:

“Joseph, son of David, do not be afraid to take Mary as your wife, for the child conceived in her is from the Holy Spirit. She will bear a son, and you are to name him Jesus, for he will save his people from their sins.”

Matthew then immediately quotes Isaiah 7:14 as fulfilled by this event: “Look, the virgin shall conceive and bear a son, and they shall name him Emmanuel.” (Matthew 1:23, NRSV.) The narrative presents the virginal conception as the direct fulfillment of a scriptural prediction.⁶

Luke’s account is told from Mary’s perspective through the annunciation scene, in which the angel Gabriel visits her directly. When Mary asks how she can conceive since she “does not know a man,” Gabriel replies:

“The Holy Spirit will come upon you, and the power of the Most High will overshadow you; therefore the child to be born will be holy; he will be called Son of God.”

Luke does not cite Isaiah 7:14. His theological emphasis falls instead on the parallel between Mary’s conception and the conception of John the Baptist by the aged and barren Elizabeth, framing both births within the tradition of miraculous divine intervention in the Hebrew scriptures.⁷ Despite these different framings, both accounts agree on the core claim: Mary was a virgin who conceived through divine agency, without a human father.

Raymond Brown’s landmark commentary on the infancy narratives, still the standard reference in the field, concluded that the two accounts were composed independently — Matthew and Luke each developed a virginal conception tradition without knowledge of the other’s text — and that neither account preserves a continuous historical memory traceable to Mary or Joseph themselves.¹ Brown, a committed Catholic scholar, nonetheless concluded that the historicity of the virgin birth could not be established by historical-critical methods.

The Isaiah 7:14 problem: almah and parthenos

The entire prophetic foundation of Matthew’s virgin birth claim rests on Isaiah 7:14. The problem is that the Hebrew text of Isaiah does not use the word for virgin. The Hebrew reads ha-almah harah ve-yoledet ben — “the young woman is with child and shall bear a son.”⁹ The word almah (עַלְמָה) means a young woman of marriageable age; it carries no implication of virginity. The Hebrew Bible has a distinct, unambiguous word for virgin — betulah (בְּתוּלָה) — which Isaiah does not use here.¹⁰

The Septuagint, the Greek translation of the Hebrew scriptures produced in Alexandria beginning around the third century BCE, rendered almah as parthenos (παρθένος) — a Greek word that does primarily mean “virgin.”⁸ This translation choice, whatever motivated it, introduced a reading not present in the Hebrew original. Matthew, writing in Greek and citing scripture from the Septuagint rather than from the Hebrew, quoted the parthenos version and built his theological argument on it.⁶ The claim that the virgin birth fulfills a Hebrew prophecy therefore depends entirely on a translation that diverges from the original text.

The context of the Isaiah passage compounds the difficulty. Isaiah 7:14 was addressed to King Ahaz of Judah during the Syro-Ephraimite War of the eighth century BCE. The prophet was offering Ahaz a sign that the two kings threatening Jerusalem would be defeated before a child born in that time had grown old enough to distinguish good from evil (Isaiah 7:16, NRSV). The sign was explicitly for Ahaz, in his own historical crisis — not for a reader eight hundred years in the future.⁹ Old Testament scholars are nearly unanimous that the passage was not intended as a prediction of a distant messianic birth but as a near-term reassurance to a specific king in a specific military situation.¹⁰ Matthew’s use of it as a fulfillment proof text is what scholars call a “pesher” or contemporizing interpretation — a reading strategy in which a historical text is reapplied to present circumstances, familiar from the Dead Sea Scrolls — rather than a straightforward prediction-and-fulfillment structure.¹

Two genealogies, one problem

Both Matthew and Luke open their accounts of Jesus with genealogies tracing his lineage from David through Joseph. The purpose is plain: to establish Jesus’s messianic credentials by grounding him in the royal line. But the two genealogies contradict each other on nearly every generation between David and Joseph, and both become logically irrelevant if Joseph was not the biological father.¹

Matthew’s genealogy runs from Abraham to David to Joseph to Jesus, tracing the line through Solomon, David’s son by Bathsheba (Matthew 1:1–16, NRSV). Luke’s genealogy runs in reverse from Jesus to Adam, tracing the line through Nathan, a different son of David (Luke 3:23–38, NRSV). The two lists agree on the patriarchs from Abraham to David, then diverge completely: Matthew names twenty-eight generations from David to Joseph; Luke names forty-three. The only point of agreement between David and Joseph is Shealtiel and Zerubbabel, two generations in the post-exilic period — and even this partial convergence may reflect the prominence of those figures in the tradition rather than a genuine genealogical link.¹

Various harmonizations have been proposed across the centuries — that one genealogy traces Mary’s line, or that one uses legal adoption — but none of these solutions has textual support. Both genealogies explicitly name Joseph as the person in the line of David.² Luke introduces his genealogy with the qualifier “being the son (as was thought) of Joseph” (Luke 3:23, NRSV), which Davies and Allison note is the evangelist’s way of flagging the tension rather than resolving it.⁶ The more fundamental problem, as E. P. Sanders observed, is that genealogies through the legal or adoptive father do not establish biological descent — and it is biological descent from David that the Hebrew prophetic tradition required of the Messiah.¹¹ If Joseph did not contribute genetically to Jesus, then neither genealogy demonstrates the Davidic descent it was constructed to demonstrate.

The silence of Paul and Mark

The Gospels of Matthew and Luke were not the first Christian documents to be written. Paul’s authentic letters — Romans, 1 and 2 Corinthians, Galatians, Philippians, 1 Thessalonians, and Philemon — were composed in the 50s CE, at least two decades before the infancy narratives.⁴ Paul shows no knowledge of a virginal conception. His most relevant statement comes at the opening of Romans, where he describes Jesus as one “who was descended from David according to the flesh and was declared to be Son of God with power according to the spirit of holiness by resurrection from the dead” (Romans 1:3–4, NRSV). The phrase “according to the flesh” (kata sarka) is the ordinary Greek expression for ordinary biological descent; it is precisely the language Paul uses elsewhere to describe natural human lineage (Romans 9:3–5, NRSV).¹³

Paul’s reference to Jesus as “born of a woman, born under the law” (Galatians 4:4, NRSV) is similarly unremarkable: “born of a woman” was a standard Hebrew idiom for ordinary human birth, used in Job 14:1 and 15:14 with no miraculous implication. Had Paul known of a virginal conception, he had ample theological motivation to say so: his entire Christology turns on the question of who Jesus was and how he related to God. His silence is not conclusive, but it is notable.¹³

The Gospel of Mark, the earliest of the four Gospels (composed around 70 CE), begins not with a birth narrative but with John the Baptist and the baptism of Jesus. Mark shows no interest in Jesus’s origins or parentage.¹² In one episode, Mark refers to Jesus as “the son of Mary” rather than “the son of Joseph,” which some scholars have taken as an indication of unusual circumstances surrounding his birth, while others read it as simply reflecting that Joseph was deceased.² Either way, Mark contains no virgin birth tradition. The Gospel of John, the latest Gospel, opens with a cosmic prologue presenting Jesus as the pre-existent Logos (John 1:1–14, NRSV) but is equally silent on the mechanics of his human conception. Significantly, John 1:45 has Philip tell Nathanael that the disciples have found “Jesus son of Joseph from Nazareth” (John 1:45, NRSV) — an identification that assumes normal paternity with no qualification or correction from the narrator.¹³

Ancient parallels: divine conception as literary convention

The attribution of miraculous or divine origin to outstanding individuals was a widespread literary and religious convention in the ancient Mediterranean world.^{3, 13} Understanding this convention is essential for interpreting the infancy narratives within their cultural context — not to dismiss the claims but to recognize the rhetorical tradition in which they participate.

Several of the most prominent figures in Greco-Roman tradition were said to have been conceived by a god. Plutarch’s Life of Alexander reports the tradition that Alexander the Great was the son of a divine serpent who had visited his mother Olympias before her marriage to Philip of Macedon.¹⁵ Suetonius’s Life of Augustus records that Augustus’s mother Atia was visited by Apollo in the form of a serpent, and that the emperor was therefore the son of the god; Suetonius notes that Augustus himself did not discourage this tradition.¹⁴ Romulus, the legendary founder of Rome, was said to be the son of Mars and the Vestal Virgin Rhea Silvia. Perseus, the Greek hero, was conceived when Zeus visited his mother Danae in a shower of gold.¹⁶ Plato was reported in later tradition to have been conceived when Apollo visited his mother before her marriage.³

In the Jewish tradition as well, miraculous births — though typically not virginal conceptions — punctuate the narrative of the Hebrew scriptures. Isaac was born to Sarah when she was past the age of childbearing; Samson, Samuel, and John the Baptist were born to women who had been barren. The annunciation pattern in Luke explicitly echoes these precedents: the angel Gabriel’s visit to Mary is patterned closely on the angelic annunciation of Isaac’s birth in Genesis 17–18 and on the birth of Samson in Judges 13.⁷

Scholars such as Bart Ehrman have argued that the divine-birth conventions of the Greco-Roman world provided an available vocabulary for early Christians who wanted to express Jesus’s unique status as Son of God.¹³ Larry Hurtado, approaching the question from a different theological angle, emphasizes that early Jewish Christianity was resistant to pagan mythological models and that the infancy narratives draw more heavily on Jewish scriptural typology than on Hellenistic divine-birth stories.¹⁸ The debate about which cultural stream is primary is ongoing; what is not disputed is that the broader literary environment in which Matthew and Luke wrote was saturated with precedents for divine-conception claims.

Theological function and independent development

The virgin birth serves a specific christological function in each Gospel. In Matthew, it establishes Jesus as the fulfillment of Israelite prophecy and as the Son of God from the moment of his conception — the culmination of a genealogy that Matthew has arranged into three sets of fourteen generations to signal a providential pattern in history (Matthew 1:17, NRSV).⁶ In Luke, the annunciation is the first of a series of angelic announcements and canticles (the Magnificat, the Benedictus, the Nunc Dimittis) that establish Jesus as the long-promised deliverer of Israel, conceived by the power of the Most High and therefore rightly called “Son of God.”⁷

Brown’s analysis concludes that the virgin birth traditions in Matthew and Luke developed independently in separate early Christian communities, each drawing on available scriptural and cultural resources to articulate the significance of Jesus’s origins.¹ The two accounts cannot be harmonized into a single coherent narrative, and neither shows awareness of the other. This independent development means the tradition cannot be traced to a single source, but it also means neither account corroborates the other in the way that independent attestation normally functions as an argument for historicity: the two accounts agree on the virgin conception but disagree on virtually every other detail, and both are absent from the earlier Pauline and Markan strata of the tradition.^{1, 2}

John Meier’s magisterial A Marginal Jew applies the standard criteria of historicity used by New Testament scholars — multiple attestation, the criterion of embarrassment, coherence, and discontinuity — and concludes that the virgin birth does not pass the tests that would commend it as historical memory. Meier notes that the virgin birth actually fails the criterion of embarrassment in the opposite direction: it was not an awkward or inconvenient claim for Matthew and Luke, but a theologically useful one.² The earliest stratum of the tradition — Paul and Mark — is simply silent, and silence in the earliest sources, where theological motivation to mention the claim would have been strong, weighs against the claim’s presence in the earliest community memory.

Scholarly consensus

Mainstream New Testament scholarship, including that of scholars who are themselves committed Christians, treats the virgin birth as a theological affirmation rather than a recoverable historical event. Raymond Brown, Geza Vermes, E. P. Sanders, John Meier, Bart Ehrman, and Joseph Fitzmyer — representing a wide range of confessional positions — converge on the view that the infancy narratives in Matthew and Luke represent independent theological developments composed decades after Jesus’s death, drawing on the Septuagint, Jewish scriptural typology, and the christological needs of early communities.^{1, 2, 3, 7, 11, 12}

The textual situation is straightforward: two Gospels assert a virgin birth; the two earliest layers of the New Testament — Paul’s letters and the Gospel of Mark — do not; the Gospel of John implicitly contradicts it by identifying Jesus as Joseph’s son without qualification. The Isaiah prophecy on which Matthew’s account rests depends on a Greek translation that diverges from the Hebrew original. The two genealogies constructed to establish Davidic descent through Joseph contradict each other and are logically undermined by the very claim they appear alongside. None of this settles the theological question of whether the virgin birth occurred; it does settle the historical-critical question of whether the claim derives from early, independent, historically reliable memory. By the standards applied uniformly elsewhere in New Testament scholarship, it does not.^{1, 2}

The virgin birth remains a confessionally significant doctrine in Catholic, Orthodox, and many Protestant traditions, affirmed in the Apostles’ Creed and the Nicene Creed. The historical-critical analysis outlined here does not address its theological status — that is a question of faith, not of textual evidence. What the evidence does show is that the tradition emerged late, developed independently in two communities, and rests on a prophetic citation whose Hebrew original does not say what Matthew’s Greek claims it says. These are the findings of the scholarly discipline, and they are not seriously contested in the academic literature.^{1, 3, 11}
