James & Joses: Brothers, Step Brothers, Cousins?

From ChatGPT on 7/1/2025.

The debate among critical Bible scholars over whether James and Joses (also spelled “Jose”) were biological sons of Mary (Jesus’ mother) or children of Joseph by a prior wife stems from differing interpretations of New Testament texts, early Christian traditions, and theological developments in later centuries. Here’s a summary of the main views and scholarly sources supporting each side:

---

View 1: James and Joses were biological sons of Mary and Joseph (Jesus’ younger brothers)

Evidence & Arguments:

1. Plain reading of the Gospels:
   • Mark 6:3 (NRSV): “Is not this the carpenter, the son of Mary and brother of James and Joses and Judas and Simon, and are not his sisters here with us?”
   • This text refers to Jesus’ brothers and sisters in a manner consistent with biological siblings.
2. Greek word adelphos (brother):
   • The Greek word used, adelphos, ordinarily means a biological brother, not a cousin or stepbrother.
   • Scholars such as John P. Meier argue that interpreting adelphos to mean “cousin” is unnatural in Koine Greek unless context requires it.
     Source: Meier, A Marginal Jew: Rethinking the Historical Jesus, Vol. 1 (1991), pp. 316–321.
3. Absence of any clear biblical mention of Joseph having other sons:
   • Nowhere in the New Testament does it state that Joseph had sons by a previous marriage.
4. Historical-critical reading:
   • Many modern scholars, like Raymond E. Brown, suggest the most straightforward historical interpretation is that these were indeed Jesus’ biological brothers.
     Source: Brown, The Birth of the Messiah (1993), pp. 103–105.
5. Earliest Christian traditions were more fluid:
   • The idea of Mary’s perpetual virginity wasn’t firmly fixed in the first century. Scholars believe the earliest followers may not have seen a problem with Jesus having biological siblings.
     Source: Bart D. Ehrman, Jesus: Apocalyptic Prophet of the New Millennium (1999), pp. 207–209.

View 2: James and Joses were sons of Joseph by another wife (Jesus’ stepbrothers)

Evidence & Arguments:

1. Support for Mary’s perpetual virginity:
   • The doctrine that Mary remained a virgin her entire life emerged early in the church (2nd–4th century), especially among church fathers like Jerome.
   • This belief led some to reinterpret “brothers” of Jesus as stepbrothers or cousins to preserve Mary’s virginity.
     Source: Jerome, Against Helvidius (c. 383 CE).
2. Protoevangelium of James (2nd century apocryphal gospel):
   • This early Christian text asserts that Joseph was an old widower who had children from a previous marriage. Jesus’ “brothers,” including James and Joses, were Joseph’s sons by his first wife.
     Source: Protoevangelium of James §9, §17.
3. Eastern Orthodox tradition:
   • The Orthodox Church often follows this view, holding that the “brothers” of Jesus were stepbrothers from Joseph’s earlier marriage.
     Source: John Breck, The Orthodox Church: Its Faith, Worship and Life (1998), pp. 90–91.
4. Absence of Mary and Joseph’s other children at Jesus’ birth:
   • Some argue that if Mary had other biological children, they would be mentioned during the nativity narratives or during the flight to Egypt.
   • Since they are not, this is used to suggest the “brothers” came from a previous marriage of Joseph.
     Source: Richard Bauckham, Jude and the Relatives of Jesus in the Early Church (1990), pp. 23–28.

Alternate View: “Brothers” as Cousins (Roman Catholic position)

Summary:

• The Roman Catholic Church traditionally holds that James and Joses were cousins, not biological brothers.
• This interpretation was defended by Jerome, who argued that adelphos could mean cousin in a Semitic context, especially in Hebrew or Aramaic.
  Source: Jerome, Against Helvidius, 4th century.
• However, most modern critical scholars reject this view because Greek has a separate word for cousin (anepsios), and the Gospel authors used adelphos consistently.

Timeline: Interpretations of James & Joses (Brothers of Jesus)

Here is a timeline tracing the development of interpretations about James and Joses, the “brothers” of Jesus, across early Christian history. It highlights how views evolved—from probable biological brothers to stepbrothers or cousins—as theology (especially Mariology) developed.

Date	Event or Source	Interpretation	Notes
30–60 CE	Paul’s Epistles (Gal 1:19)	James = “brother of the Lord” (biological)	Paul uses “brother” (adelphos) in a familial sense. No doctrine yet of Mary’s perpetual virginity.
65–85 CE	Gospels of Mark & Matthew (e.g., Mk 6:3)	James & Joses = Jesus’ brothers (biological)	Referred to naturally as brothers. No suggestion they are cousins or stepbrothers.
90–110 CE	Gospel of John	Brothers = skeptical family members	John 7:5 shows Jesus’ brothers didn’t believe in him. No theological interpretation applied yet.
110–140 CE	Papias of Hierapolis (fragmentary)	Possibly biological brothers	May imply James was Jesus’ actual brother (but texts are ambiguous).
150–180 CE	Hegesippus (quoted in Eusebius, Church History)	James = “brother of the Lord”	Hegesippus calls James a brother but doesn’t specify biological vs. stepbrother.
~150 CE	Protoevangelium of James (apocryphal gospel)	James & Joses = sons of Joseph by previous wife (stepbrothers)	Introduces the idea that Joseph was elderly and widowed. Promotes Mary’s perpetual virginity.
~200 CE	Tertullian (On the Flesh of Christ)	James = biological brother	Tertullian holds that Mary bore other children. Earliest father to clearly reject perpetual virginity.
~250 CE	Origen (Commentary on Matthew)	Leans toward stepbrothers or symbolic brothers	Follows the Protoevangelium of James tradition. Origen supports perpetual virginity.
~383 CE	Jerome’s Against Helvidius	Brothers = cousins	Argues that Mary remained a virgin; says “brothers” refers to cousins—sons of Mary’s sister.
~400 CE	Augustine of Hippo	Cousins / stepbrothers	Supports Jerome’s view. Affirms perpetual virginity and doctrinal development.
451 CE	Council of Chalcedon	Affirms Mary as “ever-virgin”	This leads to continued reinterpretation of the brothers as either stepbrothers or cousins.
500s–present	Eastern Orthodox tradition	Stepbrothers	Follows Protoevangelium of James. James & Joses = Joseph’s sons from first marriage.
Middle Ages (Latin West)	Roman Catholic Church	Cousins (Jerome’s view)	Dominant in the Western Church for centuries. Supported by scholastic theologians.
1800s–Present	Modern critical scholarship	Return to biological brothers	Historical-critical method favors the plain reading of adelphos as “brothers.” Prominent scholars: Meier, Brown, Ehrman.

Summary of Shifting Interpretations:

Period	Dominant Interpretation
1st–2nd century	Biological brothers
2nd–4th century	Stepbrothers (to support virginity of Mary)
4th–5th century	Cousins (via Jerome’s argument)
Middle Ages	Cousins (Latin West); Stepbrothers (Greek East)
Modern era	Mostly biological brothers among critical scholars
