It is a commonplace of scholarship on the epistle of Jude to lament the neglect from which the letter has suffered. However, despite the relative obscurity of the subject, a substantial number of commentaries do exist, and the major problems surrounding the epistle are clear: the nature of the heretics against whom the letter was directed, the relationship between Jude and II Peter, and the identity of the author – along with the related question of chronology. There is no unanimity in the literature, but the solutions proposed by Douglas Rowston represent a convincing resolution of the available evidence. He defines the heresy which prompted the letter as an anti-nomian gnosticism, a ‘lively libertinism’, interprets Jude as a source for II Peter, and attributes the letter to a Hellenized individual, conversant with Jewish literature, who wrote under the pseudonym of the Lord's brother in order to give his message apostolic weight in the post-apostolic age. Rowston accepts Werderman's approximate date of A.D. 80.
