FootnoteThe author of this letter identifies himself as Jude (or Judas), "the servant of Jesus Christ, and brother of James". Since James is mentioned here without further specification, it is likely that he was James the Lord's brother, who was prominent in the early church as a key leader of the believers in Jerusalem. Hence, although it is uncertain, it appears that Jude is the Judas mentioned in Matthew 13:55 and Mark 6:3 as one of the physical brothers of the Lord, the other physical brothers of Our Lord being James, Joses and Simon. The content of Jude's letter is similar to parts of the second letter of Peter; it was written to counter the influence of some false teachers who were making inroads into the church.
