The Letter of Jude has been called “the most neglected book of the New Testament.” Some classical theologians, among them Martin Luther, have held that Jude is not only dependent on but even contained in II Peter.

Or does it rather indicate a proximity to Jewish Christianity, belonging therefore with Matthew and Mark? Is it a “genuine letter,” composed for the purpose of solving a real controversy, or a treatise against heresy in general?…
