Jude was warning the Church that they had allowed false teachers to infiltrate the Body of Believers. These men were called Libertines, and their corrupt doctrine suggested that Christ’s grace released them from all authority or restraint. They believed in absolute freedom without any control by God’s moral law. Their creed was, “Our souls are saved by grace, so whatever we do with our bodies, which will perish anyway, doesn’t matter! So we can do whatever we want, whenever we want to.” But Jude saw it as blaspheme and corruption both morally and spiritually…and likened them to wild animals… without conscious or control.
