Who Was Saint Joseph: What the Gospels Really Say

Saint Joseph was the husband of the Virgin Mary and the legal father of Jesus: a Jew descended from King David, a craftsman (tekton) settled in Nazareth of Galilee, whom the Gospel of Matthew defines with a single word, “just” (Mt 1:19). The whole history of Saint Joseph that we can know with certainty fits into a few chapters of Scripture: Matthew 1-2, Luke 1-2, and brief mentions in the public life, when Jesus is recalled as the carpenter’s son (Mt 13:55), the carpenter (Mk 6:3), and the son of Joseph (Jn 6:42). It is little in quantity, but decisive in content: in these texts Joseph appears as the true husband of Mary, the father of Jesus before the law of Israel, and the guardian of the mystery of the Incarnation. This article surveys, with academic sobriety, everything the Gospels really say about him—and also what they do not say.

The Just Man of Nazareth (Mt 1:19)

The only adjective the New Testament applies directly to Joseph is the Greek díkaios, “just”: Joseph, Matthew says, was a just man (Mt 1:19—in the Nova Vulgata, cum esset iustus). In biblical vocabulary this term corresponds to the tsadiq of the Old Testament and does not denote mere legal honesty, but the integral rectitude of the man who lives before God in obedient listening. Joseph is just precisely at the most dramatic moment of his life: he discovers Mary’s pregnancy before they come to live together and, unwilling to disgrace her, resolves to divorce her quietly (cf. Mt 1:19). The angel of the Lord intervenes in a dream and reveals the origin of the Child, and the Catechism sums up the announcement with the Gospel text itself: “That which is conceived in her is of the Holy Spirit,” the angel says to Joseph about Mary, his wife (Mt 1:20—CCC 497).

Joseph’s answer is not a word, it is an act. Saint John Paul II, in the exhortation Redemptoris custos, observes:

In truth, Joseph did not respond to the angel’s “announcement” as Mary did; but he “did as the angel of the Lord commanded him and took his wife.” What he did is the purest “obedience of faith” (Redemptoris custos, n. 4).

The Gospels do not record a single word spoken by Joseph. This silence, however, is not empty: “this silence of Joseph has a special eloquence: thanks to this attitude, one can fully grasp the truth contained in the judgment that the Gospel gives us of him: the ‘just man’ (Mt 1:19)” (Redemptoris custos, n. 17). The evangelists “speak exclusively of what Joseph ‘did’” (Redemptoris custos, n. 25), and it is precisely in that obedient doing that the man is revealed. The role of the dreams of Saint Joseph in Matthew 1-2 always follows the same pattern: divine command, awakening, immediate execution.

The Davidic Genealogy

Matthew opens his Gospel with the genealogy that descends from Abraham, passes through David, and ends in Joseph, the husband of Mary, of whom Jesus was born, who is called Christ (cf. Mt 1:16). Luke confirms the same condition: Mary was “a virgin betrothed to a man whose name was Joseph, of the house of David” (Lk 1:26-27, cited in CCC 488), and it is because of the census that Joseph goes up from Nazareth to Bethlehem, the city of David, since he was of the house and lineage of David (cf. Lk 2:4).

This fact is not ornament: it is the key to the legal messiahship of Jesus. It is through the marriage to Joseph that Jesus enters juridically into the promised Davidic line. The Catechism formulates it precisely: “God called Joseph to ‘take into his home Mary, his wife,’ pregnant with ‘the One conceived in her by the power of the Holy Spirit’ (Mt 1:20), so that Jesus, ‘who is called Christ,’ should be born of Joseph’s wife, in the messianic lineage of David (Mt 1:16)” (CCC 437). Pope Francis, in Patris corde, draws from this a conclusion of biblical theology: “As a descendant of David (cf. Mt 1:16, 20), from whose root Jesus was to be born according to the promise made to the king by the prophet Nathan (cf. 2 Sam 7), and as the husband of Mary of Nazareth, Saint Joseph constitutes the hinge that joins the Old and the New Testament” (Patris corde, n. 1).

Saint Joseph, Father of Jesus: True Fatherhood, Not Biological

Francis recalls that Jesus is “designated in the four Gospels as ‘the son of Joseph’” (Patris corde, prologue, cf. Lk 4:22, Jn 1:45, Jn 6:42), and Luke presents Joseph and Mary as the parents of the Child (cf. Lk 2:27, 41). At the same time, Matthew and Luke affirm the virginal conception without ambiguity: Joseph is not the biological father of Jesus. How are the two affirmations to be reconciled? By the matrimonial law of Israel: in Second Temple Judaism the husband (aner, cf. Mt 1:16, 19) holds juridical fatherhood over the son of his wife. Moreover, Jewish betrothal already conferred on Mary the full condition of wife, so that Joseph is a true husband even before they came to live together—a theme we explore more deeply in the article on the espousals of Mary and Joseph.

The Magisterium has taken up this reading: “As can be deduced from the Gospel texts, the marriage to Mary is the juridical foundation of Joseph’s fatherhood. It was to assure fatherly protection for Jesus that God chose Joseph as Mary’s husband” (Redemptoris custos, n. 7). And this fatherhood is not a pious fiction: “his fatherhood, however, is not merely ‘apparent,’ or only ‘substitutive’; rather, it is fully endowed with the authenticity of human fatherhood, with the authenticity of the paternal mission in the family” (Redemptoris custos, n. 21). The gesture that expresses it is the giving of the name: Joseph “had the courage to assume the legal fatherhood of Jesus, to whom he gave the name revealed by the angel: you shall give Him ‘the name of Jesus, for He will save the people from their sins’ (Mt 1:21)” (Patris corde, prologue). We devote a study of its own to the fatherhood of Saint Joseph. That same real fatherhood, exercised within a virginal marriage, is inseparable from the faith of the Church in the perpetual virginity of Mary: the “brothers of Jesus” of Mt 13:55 are explained, in the Catholic reading, by the Semitic use of “brother” for close relatives.

The Carpenter: What Tekton Means

In Nazareth, Jesus is known as the carpenter’s son (Mt 13:55) and he himself is called the carpenter (Mk 6:3): in both verses the Greek uses the term tekton, which designates, more broadly than our “carpenter,” the building craftsman: a worker in wood, but also in beams, doors, plows, and structures. It was a manual trade, modest and skilled, on which the support of the Holy Family depended. Francis sums it up: “Saint Joseph was a carpenter who worked honestly to provide for his family. With him, Jesus learned the value, the dignity, and the joy of what it means to eat bread that is the fruit of one’s own labor” (Patris corde, n. 6).

The workshop of Nazareth has a theological reach. During the hidden years, “Jesus shared the condition of the vast majority of men: a daily life without apparent greatness, a life of manual labor” (CCC 531), subject to Mary and Joseph (cf. Lk 2:51)—and that submission “was the perfect fulfillment of the fourth commandment” (CCC 532). John Paul II goes further: “Thanks to his workbench, at which he plied his trade together with Jesus, Joseph brought human work closer to the mystery of the Redemption” (Redemptoris custos, n. 22).

What the Gospels Do Not Say—and What the Apocrypha Add

The sobriety of the Gospels leaves questions open: we do not know when Joseph was born, nor when he died; we do not know his age at the espousals; we have no word of his. The last scene in which he appears alive is the finding of Jesus in the Temple, at the age of twelve (Lk 2:41-52)—“the only event that breaks the silence of the Gospels about the hidden years of Jesus” (CCC 534). In the public life, Joseph no longer appears, and the fact that Jesus entrusts Mary to the beloved disciple on the cross (cf. Jn 19:26-27) suggests that Joseph had already died. Hence the tradition of invoking him as patron of a happy death: the Church exhorts us “to entrust ourselves to Saint Joseph, the patron of a happy death” (CCC 1014).

These gaps were filled by the apocrypha, above all the Protoevangelium of James (second century) and the History of Joseph the Carpenter: Joseph as an elderly widower with children from a first marriage, the flowering rod that designates him as husband, the serene death between Jesus and Mary. The Church is cautious with these texts for a reason of method: they do not belong to the canon, they are late and visibly legendary, and they are valuable as cultural context and as a source of iconography (the aged Joseph of so many paintings), not as a doctrinal source. Catholic Josephology is built upon the biblical datum read within the living tradition, not upon legend—a criterion we set out in our pillar article on Josephology.

Synthesis: Who Saint Joseph Was

Who was Saint Joseph, according to the Gospels? A just man of Israel, of the house of David, a craftsman of Nazareth, the virginal husband of Mary and the true father of Jesus by the marriage bond and by the effective exercise of the paternal mission: to give the name, to protect, to provide, to educate. John Paul II condenses his greatness into a formula: “Saint Joseph was called by God to serve the Person and the mission of Jesus directly, through the exercise of his fatherhood: in precisely this way he ‘cooperates in the great mystery of the Redemption, when the fullness of time comes,’ and is truly a ‘minister of salvation’” (Redemptoris custos, n. 8). And Francis recalls the unique place that resulted from this in the Catholic faith: “After Mary, the Mother of God, no saint occupies as much space in the papal Magisterium as Joseph, her spouse” (Patris corde, prologue). The little that Scripture says is enough: Joseph is the man who did what God commanded, and in that lies his whole biography.
