The letters of Jude and Second Peter

Aichele uses the framework of semiotics to approach the New Testament books Jude and 2 Peter. The letter of Jude has a strong resemblance to a section of 2 Peter. Both use an authoritarian title for Christ which is absent everywhere else in the New Testament. Both are concerned about the corruption of the Church by alternative ideas claiming to be Christian. But the books have differences from each other as well.
