The half brother of Jesus Christ is likely the author of Jude. The writer gives his name and identifies himself as James’s brother, and the possibility exists that he can be the brother of one of four James, which creates some uncertainty among scholars. Jude writes to Christians who have been infiltrated by false teachers and people spreading the message that promotes immorality, theological error, destructive pride and divisiveness. Jude encourages his readers to stand firm against the pressure to dilute pure Christian doctrine.
