Jude, epistle of the New Testament, the next to last book of the Bible. The Jude who wrote it has been identified since ancient times with St. Jude the apostle, but most modern scholars deny the identity and date the letter as late as A.D. 100. It is called a Catholic (or General) Epistle, but it is clearly intended for a particular audience, which it warns against some heresy that led to immorality. The dangers are shown from Old Testament examples. The book contains references to Jewish apocryphal books, Enoch and the Assumption of Moses. It ends with a doxology. Jude has a close literary relationship with Second Peter.
