The Epistles of Peter and Jude stand in close relationship to one another because of their subject matter, especially Second Peter and Jude. Peter's epistles contain eighty-four hapax legomena, words only occurring once. This is a high percentage when one considers how brief both his letters are. The knowledgeable and skillful writer Silvanus might have been Peter's amanuensis (cf. 1 Pet. 5:12-14), which would account for Peter's superb Greek style and extant vocabulary.
In both content and style, the Second Epistle of Peter is very different from the First Epistle of Peter. His expression in Greek is according to the purpose he had in mind when authoring these letters. Both in Peter and Jude's letters are passages that are beset with grammatical, exegetical, and syntactical difficulties, all of which make their diagramming analysis tantalizing.
Epistle of Jude is more like a tract than a letter, although it has an address at the beginning and closes with a liturgical form. Jude's letter is strong and dignified. The letter contains fifteen words that are not found anywhere else in the Greek New Testament. Thus, in my opinion, the Epistle of Jude is the twenty-sixth (out of twenty-seven) most difficult work to read in the Greek New Testament. It was written in a distinctive Hellenistic style while incorporating the distinctive character of Koiné Greek.
