Direct answer: In the New Testament, Jesus is described as having siblings—primarily four brothers named James, Joses (often rendered Joseph), Simon, and Judas (often called Jude)—and at least two unnamed sisters. The brothers are mentioned in Mark 6:3 and Matthew 13:55, while the sisters are referenced but not named in Mark 6:3 and Matthew 13:56. The Gospel accounts also show a complex pattern: Jesus’ brothers initially doubt him or are absent from his ministry, but they later appear with the disciples in Acts 1:14. The traditional interpretation among many Christian traditions is that these siblings were Jesus’ maternal half-siblings, children of Mary and Joseph. Different Christian groups have varied views on whether Mary remained a perpetual virgin and how to understand the term “brothers” in this context, but the biblical texts name four brothers explicitly and imply at least two sisters.
