Catholic Dude:
There were two apostles named James, but neither of them had a father named Joseph.
Correct. These two were James the Greater, who was the son of Zebedee and the brother of John; and James the Less, who was the son of Alphaeus and the brother of Matthew.
However, there is a
third James in Scripture, James the Righteous; and
this is the James who is called “the Lord’s brother” in Galatians 1:19. He was also the bishop of Jerusalem (Acts 21:17-18) and probably the author of the Epistle of James.
So, we have James the Righteous who is called “the Lord’s brother”. But was he the child of Joseph and Mary?
Luke 2:7 tells us that Jesus was Mary’s
first-born son. This means that if James was the child of Joseph and Mary, he would have been born after Jesus was.
So, was he?
Scripture says nothing more past this, so if you’re depending on Scripture alone, you are free to draw your own conclusions. However, as has been pointed out, there are a number of other ancient documents which tell a different story.
Hegesippus, Josephus, and Eusebius all mention James, identify him as “the Lord’s brother”, and recount his martyrdom, but two other documents give us more specific information for our purposes here.
The
Protoevangelion of James (9:2) was written between 150 and 180 AD, and recounts the story that Joseph was chosen by the priest and the local council to be Mary’s husband, she being about 16 years old. Joseph replies, “Why do you bring her to me? I am an old man, with grown sons, and she is just a girl.” So here we have a text which specifies that Joseph had sons from a previous marriage.
The second document is from Epiphanius of Salamis (315-403 AD), who wrote the
Panarion or
Adversus Haereses (377 AD); this document (78:13:2-14:5) recounts that James the Righteous was 96 years old when he was martyred in 62 AD.
This would mean that James was 34 years old when Jesus was born…and Jesus was Mary’s first-born; therefore, the only way James could have been Jesus’ brother would have been in the capacity of an older step-brother.
Take it for what it’s worth.
