Jude, which is rendered “Judah” in Hebrew and “Judas” in Greek, was named after its author (v. 1), one of the 4 half-brothers of Christ (Matt. 13:55; Mark 6:3). As the fourth shortest NT book (Philem., 2 John, and 3 John are shorter), Jude is the last of 8 general epistles. Jude does not quote the OT directly, but there are at least 9 obvious allusions to it. Contextually, this “epistolary sermon” could be called “The Acts of the Apostates.”
