Detailed Response
The Scriptural Reference to “Brothers”
The question of St. James the Just’s identity begins with Scripture, where he is named among the “brothers” of Jesus in Matthew 13:55 and Mark 6:3. These passages list James, Joseph (or Joses), Simon, and Judas as Jesus’ brothers, alongside unnamed sisters. Many modern interpreters take this language at face value, assuming these were biological siblings born to Mary and Joseph after Jesus. However, this interpretation overlooks the cultural and linguistic context of the time. In ancient Jewish society, the term “brother” was not limited to immediate siblings but extended to cousins, nephews, and other male relatives. This broader usage is well-documented in both the Old and New Testaments. For example, Abraham calls Lot his “brother” in Genesis 13:8, though Lot was his nephew. Similarly, 1 Chronicles 23:22 refers to cousins as “brothers.” Thus, the mention of James as a “brother” does not necessitate a shared mother or father with Jesus. Catholic tradition interprets this term in its wider sense, preserving Mary’s perpetual virginity as a fundamental doctrine (see Catechism of the Catholic Church, 499-500).
The Perpetual Virginity of Mary
Central to this discussion is the Catholic belief in Mary’s perpetual virginity, a teaching held since the early Church. This doctrine asserts that Mary remained a virgin before, during, and after the birth of Jesus. Some modern scholars argue that the existence of Jesus’ “brothers,” like James, disproves this claim, suggesting Mary had other children naturally with Joseph. Yet, this view contradicts the consistent testimony of Church Fathers and early Christian writings. The Protoevangelium of James, an early second-century text, describes Mary as dedicated to God from childhood, living a life of perpetual consecration. The Church has never wavered on this point, seeing her virginity as a sign of her total dedication to God’s plan. If James were her biological son, it would undermine this ancient belief. Scripture itself offers no evidence that Mary bore additional children; rather, it emphasizes her unique role as the mother of the Savior (Luke 1:35). The “brothers” must therefore be understood as relatives, not sons. This aligns with the Church’s authoritative teaching on Mary’s singular vocation.
The Two Traditional Views
Within Catholic tradition, two explanations have emerged to identify Jesus’ “brothers,” including James. The first, known as the Epiphanian view, posits that these “brothers” were children of Joseph from a previous marriage. Named after St. Epiphanius of Salamis, this perspective sees Joseph as a widower who brought children into his union with Mary. The second, the Hieronymian view, advanced by St. Jerome, argues that “brothers” refers to cousins or other extended relatives. Jerome’s explanation draws on his deep knowledge of Jewish customs and Semitic languages. Both views protect Mary’s perpetual virginity, but they differ in their approach to James’ parentage. The Epiphanian view suggests James could be Joseph’s son, though not Mary’s, while the Hieronymian view denies any direct familial tie to either parent of Jesus. Historically, the Church has not mandated one view over the other, but both reject the notion of James as Mary’s son. Scholarly analysis favors Jerome’s interpretation for its consistency with scriptural language. Either way, these traditions refute the idea of James as a literal brother.
Problems with the Epiphanian View
The Epiphanian view, while ancient, faces significant challenges when scrutinized against Scripture. If James were Joseph’s son from a prior marriage, one might expect him to be older than Jesus, yet this is not implied anywhere in the New Testament. More critically, Matthew 27:56 and Mark 15:40 identify the mother of James and Joses as a woman present at the crucifixion, distinct from Mary, the mother of Jesus. This woman is named “Mary the mother of James and Joses,” separate from “Mary the mother of Jesus” in John 19:25. If Joseph were James’ father, this other Mary would have to be Joseph’s first wife, still alive during Jesus’ ministry. However, no tradition supports Joseph having multiple wives simultaneously, which would contradict Jewish norms of the time. Furthermore, the Epiphanian view arose among Greek Fathers less familiar with Jewish customs, possibly as a pastoral simplification. St. Jerome, with his expertise in Hebrew and Aramaic, criticized this idea as unnecessary. The presence of James’ mother as a distinct figure undermines the Epiphanian claim. Thus, this view cannot sustain the argument that James was Joseph’s son by another woman.
The Strength of the Hieronymian View
St. Jerome’s Hieronymian view offers a more compelling explanation rooted in Jewish linguistic practices. He argued that “brother” in Matthew 13:55 and Mark 6:3 denotes cousins or other kin, not literal siblings. This aligns with the flexible use of “adelphos” (Greek for “brother”) in the New Testament, reflecting Semitic conventions. For instance, Acts 1:15-16 uses “brothers” to address a group of unrelated believers. Jerome’s fluency in Hebrew and his collaboration with Jewish scholars lent credibility to his analysis. He pointed out that John 19:25 lists “Mary the wife of Clopas” alongside Jesus’ mother, suggesting she could be the mother of James and Joses. This Mary is described as a “sister” to Jesus’ mother, likely meaning a close relative. If James were her son, he would be Jesus’ cousin, not brother. The Hieronymian view thus resolves the identity of the “brothers” without contradicting Mary’s virginity. It remains the most widely accepted Catholic interpretation today.
James’ Mother at the Crucifixion
Scripture provides a key clue in identifying James’ true parentage through the women at the crucifixion. John 19:25 lists three or four women: Mary the mother of Jesus, her “sister” Mary the wife of Clopas, and Mary Magdalene (depending on punctuation). Meanwhile, Matthew 27:56 and Mark 15:40 name Mary the mother of James and Joses as present, alongside other women. Catholic exegesis often identifies this Mary with the wife of Clopas, distinguishing her from Jesus’ mother. This separation is critical: if James’ mother was not Mary the mother of Jesus, he cannot be her son. The text never suggests that Mary bore additional children who were also at the cross. Instead, it portrays distinct family units among Jesus’ followers. Early Church Fathers, like St. Augustine, affirmed this reading, seeing no conflict with Mary’s virginity. The consistent naming of James’ mother as a separate figure supports the Hieronymian view. Thus, James emerges as a relative, not a sibling, of Jesus.
James as a Levite
Historical sources further complicate the idea of James as Joseph’s son by identifying him as a Levite, a member of the priestly tribe. The early Christian historian Hegesippus, cited by Eusebius (Ecclesiastical History, Book II, Chapter 23), describes James entering the Temple’s Holy Place, a privilege reserved for Levites. He wore linen garments, typical of priests, and was known for interceding for the people. This Levitical status aligns with Mary’s own family ties, as her relative Elizabeth was of the tribe of Levi (Luke 1:5, 1:36). Joseph, however, belonged to the tribe of Judah, of David’s lineage (Luke 1:27). In Jewish tradition, tribal identity passed through the father, so James could not be a Levite if Joseph were his father. This evidence decisively rules out Joseph as James’ parent. Instead, James likely descended from a Levitical line through his mother, Mary of Clopas. Hegesippus’ account, written in the second century, carries significant weight as a near-contemporary source. Catholic teaching embraces this as consistent with Scripture and tradition.
Leadership in the Early Church
Some argue that James’ leadership of the Jerusalem church, as seen in Acts 15:13-21, implies he was Jesus’ sibling, inheriting authority as a family member. This view draws parallels with dynastic succession in other Semitic cultures. However, this assumption misreads both Scripture and historical context. Acts 12:17 shows Peter appointing James to lead after escaping prison, indicating an apostolic choice, not a familial one. James’ prominence stemmed from his righteousness and reputation, not blood ties. Hegesippus calls him “the Just,” emphasizing his holiness over any dynastic claim. If James were Jesus’ brother and Joseph’s son, he would share Jesus’ Davidic lineage, potentially positioning him as a Messianic heir. Yet, no early source attributes royal status to James. His leadership reflects spiritual authority, not kinship. The Catholic Church sees this as evidence of his role as a cousin or relative, not a sibling.
James and Herod’s Persecution
The events of Acts 12 further undermine the sibling theory. King Herod Agrippa I targeted church leaders, killing James the son of Zebedee and arresting Peter (Acts 12:1-3). If James the Just were Jesus’ brother and a Davidic heir, he would have been a prime target as a potential rival to Herod’s throne. Jesus’ Messianic claim, tied to David’s line through Joseph, threatened Roman and Herodian authority. A literal brother leading the Jerusalem church would have drawn immediate persecution. Yet, James remained in charge after Peter’s departure (Acts 12:17), suggesting he posed no dynastic threat. His survival under Herod’s reign indicates he lacked the royal lineage a son of Joseph would possess. Early Christians recognized Jesus alone as the Davidic Messiah (Matthew 1:1). James’ role was administrative and pastoral, not political. This historical reality supports his identity as a non-sibling relative.
James’ Reputation for Holiness
James’ extraordinary holiness, as recorded by Hegesippus, provides a final compelling argument. He was called “the Just” from Jesus’ time, abstaining from wine, meat, and other comforts, and praying constantly in the Temple. This asceticism earned him widespread respect among Jews and Christians alike. If he were Mary’s son, his sanctity might have led some to question his parentage, suspecting divine origins akin to Jesus’. Yet, Scripture and tradition never address such speculation, implying it was unnecessary. James is consistently called “the brother of the Lord” (Galatians 1:19), not “son of Mary” or “son of Joseph.” His holiness reflects personal devotion, not a shared womb with Jesus. The absence of any clarification about his father suggests he was not born of Mary’s marriage. Catholic tradition celebrates his virtue while distinguishing him from Jesus’ immediate family. This reinforces the Church’s teaching on Mary’s perpetual virginity.
Conclusion: Affirming Catholic Doctrine
The cumulative evidence—scriptural, historical, and traditional—demonstrates that St. James the Just could not have been the literal brother of Jesus Christ. The term “brother” reflects Jewish custom, not biological kinship. Mary’s perpetual virginity, affirmed by the Church Fathers and the Catechism (499-500), excludes her bearing other children. The Hieronymian view, supported by Jerome’s scholarship, identifies James as a cousin, likely the son of Mary of Clopas. His Levitical heritage and leadership role align with this conclusion, not with descent from Joseph. Modern challenges to Catholic teaching often ignore these facts, favoring speculation over evidence. James’ distinct mother, his lack of Davidic status, and his survival under Herod all point to a non-sibling relationship. His holiness, while remarkable, required no defense against divine parentage claims, as he was not Mary’s son. The Catholic position rests on a coherent synthesis of sources. Thus, St. James stands as a faithful relative of Jesus, not His brother, upholding the Church’s ancient faith.
