David Trobisch on the Protoevangelium of James vs. the Gospel of Matthew on Mary's Postpartum Virginity

  

Filing in Narrative Gaps

 

The Infancy Gospel of James answers numerous other questions in his gospel book by providing episodes not contained in the Canonical Edition. For example, how could Mary have been born without sin? Answer: Mary’s mother, Anna, conceived without having sex (chapter 4). How could Jesus be Mary’s only child if he had brothers and sisters? Answer: The other children were from Joseph’s first marriage (chapter 8). How could one know that Mary was a virgin even after giving birth? Answer: A miracle. After the birth of Jesus, skeptical Salome performed a medical exam, and she found Mary to still be a virgin (chapter 20). The assessment of Mary’s virginity is not consistent with Gospel according to Matthew, which clearly communicates that Mary and Joseph had intercourse after Jesus was born. (David Trobisch, On the Origin of Christian Scripture: The Evolution of the New Testament Canon in the Second Century [Minneapolis: Fortress Press, 2023], 47)

 

 

“When Joseph awoke from sleep, he did as the angel of the Lord commanded him; he took her as his wife but had no marital relations with her [καὶ οὐκ ἐγίνωσκεν αὐτὴν] until she had borne a son; and he named him Jesus” (Matt 1:24–25). The story implies that Joseph and Mary had sex after Jesus was born. According to the editorial narrative of the Canonical Edition, Jesus had four brothers and at least two sisters. “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?” (Mark 6:3). “Is not this the carpenter’s son? Is not his mother called Mary? And are not his brothers James and Joseph and Simon and Judas? And are not all his sisters with us?” (Matt 13:55–56). According to the editorial narrative of the Canonical Edition, the Letters of James and Jude were written by Jesus’s brothers. (Ibid., 151 n. 22)
