How many actual brothers did Jesus have?
Mark 6:3 tells us that Jesus had four younger brothers and at least two sisters, the children of Mary and Joseph. The sisters’ names have not been preserved, but the brothers were called James (in the Hebrew, Jacob), Joses (in the Hebrew, Joseph, after his father), Simon, and Judas or Juda (also known as Jude).
Who was Jesus’s twin brother?
Didymos is Greek for twin. The implication here is that he is Jesus’ twin. But this character, of course, also appears in the Gospel of John, he’s one of the disciples, the twin.
Is James the biological brother of Jesus?
Catholics and Eastern Orthodox Christians teach that James, along with others named in the New Testament as brothers of Jesus, were not the biological children of Mary, mother of Jesus, but were possibly cousins of Jesus, or step-brothers from a previous marriage of Joseph (as related in the Gospel of James).
