Saint Joseph was the husband of the Virgin Mary and the legal father of Jesus: a Jew descended from King David, a carpenter (tekton) settled in Nazareth, Galilee, whom the Gospel of Matthew describes with a single word, ‘righteous’ (Mt 1:19). All the history of Saint Joseph that we can know for certain fits into a few chapters of Scripture: Matthew 1-2, Luke 1-2, and brief mentions during Jesus’ public life, when He is referred to as the carpenter’s son (Mt 13:55), the carpenter (Mk 6:3), and Joseph’s son (Jn 6:42). Though limited in quantity, it is decisive in content: in these texts, Joseph appears as Mary’s true husband, Jesus’ father before Israeli law, and guardian of the mystery of the Incarnation. This article explores, with academic soberness, all that the Gospels actually say about him – and also what they do not say.

The Righteous of Nazareth (Mt 1:19)

The only adjective directly applied to Joseph in the New Testament is the Greek díkaios, ‘righteous’: Matthew tells us that Joseph was righteous (Mt 1:19 – in the New Vulgate, cum esset iustus). In biblical vocabulary, this term corresponds to tsadiq of the Old Testament and does not merely denote legal honesty, but the integrity of a man who lives before God in obedient listening. Joseph is righteous precisely at the most dramatic moment of his life: he discovers Mary’s pregnancy before cohabitation and, rather than defaming her, decides to send her away secretly (cf. Mt 1:19). The Lord’s angel intervenes in a dream and reveals the origin of the Child, and the Catechism summarizes the announcement with the very text from the Gospel: ‘What is conceived in her is from the Holy Spirit,’ says the angel to Joseph about Mary, his wife (Mt 1:20 – CIC 497).

Joseph’s response is not a word, but an act. Pope John Paul II, in the Exhortation Redemptoris Custos, observes:

To be sure, Joseph did not respond to the ‘announcement’ of the angel like Mary; but he ‘did as the angel of the Lord commanded him’ and took Mary as his wife (Redemptoris Custos, n. 4).

The Gospels do not record a single word spoken by Joseph. However, this silence is not empty: ‘This silence of Joseph has special eloquence: thanks to such an attitude, one can fully grasp the truth contained in the judgment made of him by the Gospel: “the righteous” (Mt 1:19)’ (Redemptoris Custos, n. 17). The evangelists ‘speak exclusively of what Joseph did’ (Redemptoris Custos, n. 25), and it is precisely in this obedient action that a man’s character is revealed.

The Davidic Genealogy

Matthew opens his Gospel with a genealogy tracing Abraham back to David, then to Joseph, the husband of Mary from whom Jesus, called Christ, was born (cf. Mt 1:16). Luke confirms the same status: Mary was ‘a virgin betrothed to a man of the house of David named Joseph’ (Lk 1:26-27, cited in CIC 488), and it is because of a census that Joseph travels from Nazareth up to Bethlehem, the city of David, as he was of David’s lineage and house (cf. Lk 2:4).

This fact is not an ornament; it is the key to Jesus’ legal messianic descent. It is through marriage with Joseph that Jesus enters legally into David’s promised lineage. The Catechism accurately states: “Joseph was invited by God to ‘take Mary, his wife, who was pregnant by the power of the Holy Spirit’ (Mt 1:20), so that Jesus, ‘called Christ,’ would be born from Joseph’s wife, in the messianic descent of David (Mt 1:16)” (CIC 437). Pope Francis, in his letter Patris corde, draws a biblical theological conclusion from this: “As a descendant of David (cf. Mt 1:16.20), from whose root Jesus was to be born according to the promise made to King David by the prophet Nathan (cf. 2 Sam 7), and as husband of Mary of Nazareth, Saint Joseph constitutes the hinge that joins the Old and New Testaments” (Patris corde, n. 1).

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

Francis reminds us that Jesus is referred to in the four Gospels as “the son of Joseph” (cf. 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 without ambiguity Jesus’ virgin conception: Joseph is not His biological father. How do we reconcile these two statements? Through Israel’s matrimonial law: in Second Temple Judaism, the husband (aner, cf. Mt 1:16, 19) holds legal paternity over his wife’s child. Furthermore, Jewish betrothal already conferred upon Mary the full status of a wife, so Joseph is a true husband even before cohabitation – a topic we delve into in our article on Maria and Joseph’s Betrothal.

The Magisterium has embraced this interpretation: “As can be deduced from the Gospels, Mary’s marriage to Joseph forms the legal basis for his paternity. God chose Joseph as Mary’s husband to ensure Jesus’ paternal protection” (Redemptoris custos, n. 7). And this paternity is not a mere fiction; “his paternity, however, is not merely ‘apparent’ or ‘substitute’; but it is fully authentic human paternity, the authenticity of the fatherly mission within the family” (Redemptoris custos, n. 21). The act that expresses this is naming: Joseph “had the courage to assume legal paternity for Jesus, whom he gave the name revealed by the angel: ‘You shall call his name Jesus, for he will save his people from their sins’ (Mt 1:21)” (Patris corde, prologue). We dedicate a separate study to Saint Joseph’s Paternity. This same real paternity, exercised within a virgin marriage, is inseparable from the Church’s faith in Mary’s Perpetual Virginity: Jesus’ “brothers” in Mt 13:55 are explained by Catholic interpretation of the Semitic term ‘brother’ as a relative term.

The Carpenter: What Does Tekton Mean?

In Nazareth, Jesus is known as the son of a carpenter (Mt 13,55) and He Himself is called a carpenter (Mk 6,3): in both verses, the Greek uses the term tekton, which designates, more broadly than our “carpenter,” the construction artisan: a woodworker, but also beams, doors, plows, and structures. It was a manual, modest, and skilled trade, from which the Holy Family’s sustenance depended. Francis summarizes: “Saint Joseph was a carpenter who worked honestly to provide for his family. With him, Jesus learned the value, dignity, and joy of earning one’s bread through one’s own labor” (Patris corde, n. 6).

The workshop in Nazareth holds theological significance. During His hidden years, “Jesus shared the condition of the vast majority of men: a daily life without apparent grandeur, a life of manual labor” (CIC 531), subject to Mary and Joseph (cf. Lk 2,51) – and this submission “was the perfect fulfillment of the Fourth Commandment” (CIC 532). John Paul II goes further: “Thanks to his workshop, where he practiced his craft alongside Jesus, Joseph brought human labor closer to the mystery of Redemption” (Redemptoris custos, n. 22).

What the Gospels Do Not Say – and What the Apocrypha Adds

The soberness of the Gospels leaves questions unanswered: we do not know when Joseph was born or died, nor his age at marriage, and we have no words from him. The last scene in which he appears alive is Jesus’ encounter in the Temple at twelve years old (Lk 2,41-52) – “the only event that breaks the silence of the Gospels about Jesus’ hidden years” (CIC 534). In public life, Joseph no longer figures, and the fact that Jesus entrusted Mary to the beloved disciple on the cross (cf. Jn 19,26-27) suggests that Joseph was already deceased. Hence the tradition of invoking him as the patron of a good death: the Church exhorts us “to entrust ourselves to St. Joseph, patron of a good death” (CIC 1014).

These gaps were filled by the apocrypha, especially the Protoevangelium of James (2nd century) and the History of Joseph the Carpenter: Joseph as an elderly widower with children from a previous marriage, the blossoming staff that designates him husband, his peaceful death between Jesus and Mary. The Church is cautious about these texts for a methodological reason: they are not part of the canon, they are late, and clearly legendary, and they serve as cultural context and source for iconography (the elderly Joseph in so many paintings), not as doctrinal sources. Catholic Josefology builds on the biblical data read within living tradition, not on legend – a criterion we outline in our cornerstone article on Josefology.

Synthesis: Who Was Saint Joseph?

Quem foi São José, segundo os Evangelhos?

Saint Joseph was a just man of Israel, descendant of the house of David, artisan of Nazareth, virginal spouse of Mary and true father of Jesus through the marital bond and the effective exercise of his paternal mission: to give the name, protect, sustain, educate. John Paul II sums up his greatness in the formula: “Saint Joseph was called by God to serve directly the Person and the mission of Jesus, through the exercise of his fatherhood: thus, precisely, he ‘cooperates in the great mystery of Redemption when it comes to the fullness of time’, and is truly a ‘minister of salvation'” (Redemptoris custos, n. 8). Francis highlights the unique place this conferred on Catholic faith: “After Mary, Mother of God, no Saint occupies as much space in the pontifical magisterium as Joseph, her spouse” (Patris corde, prologue).

The little that Scripture says about him is enough: Joseph is the man who did what God commanded, and this sums up his entire biography.

Perguntas Frequentes

Quem foi São José?

Saint Joseph was the husband of the Virgin Mary and the legal father of Jesus, a Jew descended from King David, residing in Nazareth in Galilee and a carpenter (tekton). The Gospel of Matthew describes him as “just” (Mt 1,19). He protected and provided for the Holy Family in silent obedience to the divine commands received in dreams.

São José é realmente pai de Jesus?

Yes, but not in the biological sense: Jesus was virginally conceived by the Holy Spirit (Mt 1,20). Joseph is true father by the marital right of Israel, which conferred on the husband legal paternity, and through the effective exercise of the paternal mission, beginning with the imposition of the name “Jesus” (Mt 1,21.25). Redemptoris custos teaches that this fatherhood is not apparent or substitutive, but humanly authentic.

Qual era a profissão de São José?

José was a tekton, a Greek term used in the Gospels (Mt 13,55 and Mk 6,3), translatable as “carpenter,” although the term more broadly encompasses construction artisans who worked with wood, beams, and structures. It was a manual and modest trade by which he supported his family, and beside his workbench, Jesus learned the value of human labor.

O que a Bíblia conta sobre a história de São José?

Almost everything is recorded in Matthew 1-2 and Luke 1-2: the betrothal with Mary, the crisis over her pregnancy, the dreams with angels, the birth in Bethlehem, the flight to Egypt, the return to Nazareth, and Jesus’ reunion in the Temple at twelve years old. After Lk 2,41-52, Joseph disappears from the account, suggesting that he died before Jesus’ public life. The Gospels record no words of his.

Por que a Igreja não usa os apócrifos sobre São José?

Texts such as the Protoevangelium of James and the History of Joseph the Carpenter are late, non-canonical, and visibly legendary, with details like an elderly and widowed Joseph. The Church acknowledges their value as cultural context and source of iconography but does not accept them as doctrinal sources. Theology about Saint Joseph is based on biblical testimony read in the living tradition.
