The Letter of Jude

The Epistle of Jude, with its one chapter, is among the shortest writings in the New Testament and the last of the Catholic epistles. The author is Jude, brother of James.

The letter is a call to fight for the right Christian faith and a warning to the Church against those false teachers who "abuse the grace of our God for secession." The letter is characterized by sharp condemnations of these false teachers and picturesque descriptions of the judgment against them. The text makes frequent use of images, narratives and metaphors drawn particularly from the Old Testament and other Hebrew literature.
