Jude, brother of Jesus

Jude (alternatively Judas or Judah) is believed by some to be one of the four brothers of Jesus (Greek: ἀδελφοὶ, translit. adelphoi, lit. 'brethren') according to the New Testament. He is traditionally identified as the author of the Epistle of Jude, a short epistle which is reckoned among the seven general epistles of the New Testament — placed after Paul's epistles and before the Book of Revelation — and considered canonical by Christians. Catholics believe this Jude is the same person as Jude the Apostle and that Jude was perhaps a cousin, but not a brother, of Jesus.

Mark 6:3 and Matthew 13:55 record the people of Nazareth saying of Jesus: "Is not this the carpenter, the son of Mary, the brother of James, and Joses, and of Judas, and Simon? and are not his sisters here with us?". Some Protestants, such as R.V. Tasker and D. Hill, generally relate these brothers and sisters to the Matthew 1:25 indication that Joseph "knew her not until after she brought forth her firstborn" and the implication that Joseph and Mary had customary marital relations thereafter. But K. Beyer points out that Greek ἕως οὗ (until) after a negative "often has no implication at all about what happened after the limit of the 'until' was reached".
