Jude (alternatively Judas or Judah), was an apostle often called "brother of Jesus of Nazareth", mentioned in the New Testament. He is traditionally identified as the author of the Epistle of Jude, a short epistle which is reckoned among the seven catholic epistles of the New Testament. Because this letter quotes from the apocryphal book of Enoch it is rejected by many. Nevertheless by age and use it has gained authority and is considered canonical by Christians.
