Before sea maps and the appearance of contemporary forms for warning for reefs, ships used for navigation text-based books called peripli and rutters. They described the dangerous zones that had to be avoided. The letter of Jude is a text-based book on itself for navigation and avoiding dangerous spiritual reefs for the church. Jude says: in the past there have been people who have headed this direction. They rejected God’s word and God’s authority. And they all shipwrecked. God points to shipwrecks in the past so that we would not repeat them in the present.
