The letter of Jude was written primarily to encourage faithfulness in the midst of disobedience and influence from false teachers. It draws on multiple examples of false teachers including, notably, an example from the pseudepigraphical book of 1 Enoch. The letter is also notorious among scholars for being difficult to date and determining if the letter was written by Jude or perhaps an authoritative teacher from the same community.
