Notice who is speaking in Mat 13:55 ... the words are spoken by unbelieving people in Nazareth who regarded Joseph as Jesus' biological father. Context is crucial.
Mark, pointing out that the crowd “regarded Joseph as Jesus’ biological father” doesn’t help your argument — it proves my point.
Matthew’s Gospel makes clear that Joseph is
not Jesus’s biological father:
- Matthew 1:18, 20
- Luke 1: 34–35
- Luke 3:23
So the crowd’s belief is
mistaken.
And if the crowd is mistaken about Joseph’s biological relationship to Jesus, then their statement
cannot be treated as authoritative genealogical evidence about James, Joseph, Simon and Judas.
You can’t say:
- “The crowd believed Joseph was Jesus’s biological father,” even though Matthew says that belief is wrong,
but then insist:
- “The crowd must be correct about Jesus's brothers James, Joseph, Simon and Judas,”
when both claims come from the
same unbelieving, mistaken crowd in the same sentence.
That is not
“context.”
That is
selective acceptance based on the conclusion you want.
And nothing in the text requires “same womb.”
In biblical Greek,
adelphos/adelphoi regularly includes cousins, nephews, and other male relatives. So the crowd could easily be using
adelphoi ("brothers") in the ordinary Jewish sense of
“kinsmen, or relatives” just as Scripture consistently does.
And you're discarding the verses that clarify the relationship of James, Joseph, Simon and Judas to Jesus (
Matthew 27:56; Mark 15:40, 16:1; Luke 24:10; John 19:25), while fully accepting the verses that clarify Joseph’s relationship to Him (
Matthew 1:18, 20; Luke 1: 34–35, 3:23).
You can’t apply contextual correction to Joseph but forbid contextual correction to James, Joseph, Simon and Judas.
That is
selective interpretation, not consistent exegesis.
Mary, the wife of Clopas and sister-in-law of Jesus's Mother, is explicitly named
the mother of James and Joseph (Matthew 27:56; Mark 15:40; John 19:25)
— two of the men named in Matthew 13:55.
The earliest Christian writers affirm the same and add that Symeon (Simon) and Jude (Judas) are also her and Clopas's sons.
And you also agreed that
Clopas is Joseph’s brother.
So you already accept:
- Clopas is Joseph’s brother
- Mary of Clopas is the mother of James and Joseph
- Early Christian testimony identifies Simon and Jude as their siblings
So what reason do you have for accepting Joseph as Clopas’s brother and Mary as Clopas’s wife, but discarding the evidence that links Clopas and Mary's sons to Jesus’s adelphoi?
You’re
accepting half of the genealogy and discarding the half that contradicts your conclusion.
There is no verse in Matthew's Gospel that uses adelphos as other than biological siblings or spiritual brethren.
That is demonstrably incorrect. Matthew’s Gospel frequently uses
adelphos/adelphoi outside of strict biological siblings or spiritual brothers.
In biblical Greek, and within Matthew specifically,
adelphos/adelphoi are used broadly for national kinship, close associations, and community:
- Fellow Countrymen / Kinsmen:
Jesus uses adelphos in Matthew 5:22–24 when He warns against being angry with your “brother.” In this context, adelphos refers to a fellow Israelite, neighbor, or countryman — not a biological sibling and not a modern “spiritual brother."
- Familial metaphor / redefined kinship:
Jesus uses adelphoi in Matthew 12:49–50 metaphorically to describe those who do the will of His Father — including His disciples — as His “brothers,” but in a family‑redefinition context.
- Community‑level kinship (disciples):
Jesus uses adelphoi in Matthew 23:8 to refer to His followers and students as “brothers,” expressing a community‑level kinship among His disciples.
- The Apostles:
Jesus uses adelphoi in Matthew 28:10 when He tells the women to go tell His brothers to go to Galilee, specifically referencing the apostles.
Even
BDAG—
the standard Protestant Greek lexicon—notes that
adelphos/adelphoi has multiple non‑biological uses throughout the NT.
So why are you restricting adelphos/adelphoi to only “biological or spiritual brothers” within Matthew's Gospel when Matthew himself identifies James and Joseph — two of Jesus's adelphoi named in Matthew 13:55 — as sons of Mary of Clopas (Matthew 27:56), not Mary the mother of Jesus? And Mark (15:40; 16:1), Luke (24:10), John (19:25), and early Christian writers all confirm the same genealogy.
That is
selective restriction, not consistent exegesis.
If you restrict
adelphos to “
biological or spiritual brothers only” in Matthew, you end up misreading Jesus’s teaching about ordinary interactions with
fellow Israelites,
neighbors, and the
broader community. Matthew uses
adelphos/adelphoi in multiple non‑biological senses, and
the rigid rule you’re imposing simply isn’t in the text.
