Outside the book of Jude, a "Jude" is mentioned five times in the New Testament: three times as Jude the Apostle, and twice as Jude the brother of Jesus (aside from references to Judas Iscariot and Judah (son of Jacob)). Debate continues as to whether the author of the epistle is either, both, or neither. Some scholars have argued that since the author of the letter has not identified himself as an apostle and actually refers to the apostles as a third party, he cannot be identified with Jude the Apostle. Others have drawn the opposite conclusion, i.e., that, as an apostle, he would not have made a claim of apostleship on his own behalf.
