Jesus had at least four brothers named James, Joseph (also called Joses), Simon, and Judas (Jude), according to the Gospels of Mark and Matthew (Mark 6:3; Matthew 13:55)

. In addition to these brothers, Jesus also had sisters, but their number and names are not specified; the texts imply there were at least two sisters (Mark 6:3; Matthew 13:56)

. The exact number of siblings is not definitively stated, but the minimum count is six siblings: four brothers and at least two sisters

. There are different interpretations about the nature of these siblings-some traditions hold they were Jesus' biological brothers and sisters, while others suggest they might have been cousins or step-siblings, but the biblical text most straightforwardly presents them as his siblings

. In summary:

• Brothers named: James, Joseph (Joses), Simon, Judas (Jude)
• Sisters: at least two, unnamed
• Total siblings: at least six

These siblings appear in various Gospel passages and are mentioned as initially skeptical of Jesus but later became followers after his resurrection (Acts 1:14; John 7:3-5)
