Jude describes the false teachers as “spots in your love feasts.” He likely refers to common interaction amongst Christians due to their love for one another. This often included feasting (cf. Acts 2:46). However, we note that such feasts were forbidden in the assembly (cf. 1 Corinthians 11:17-22). These “certain men” were causing harm to the saints by being with them. Their motivation was purely selfish, and was without regard for God.

Jude compares these false teachers to a few physical things: “hidden reefs” (NASV); “clouds without water”; “late autumn trees without fruit”; “raging waves of the sea”; “wandering stars.” These descriptions speak of the false teacher’s deception, erratic and disobedient behavior, and their destructive end. There is nothing good about a false teacher.

Jude alludes to prophecy spoken by God through Enoch to describe the end of those who teach false doctrine, and act in ungodly ways. The Lord is going to return for the purpose of judgment. All who live in disobedience, and speak against God, will ultimately be punished for their ungodly deeds. We must take heed how we live, for God will judge us in the end (cf. Hebrews 4:13; Acts 17:30-31; Romans 2:6-10).
