Jude, a servant of Jesus Christ and brother of James, greets those who are called, beloved in God the Father and kept for Jesus Christ. He had wanted to write about the salvation they share, but now urges them to contend for the faith once for all delivered to the saints. Certain ungodly people have crept in, long ago designated for condemnation, who turn the grace of God into sensuality and deny our only Master and Lord, Jesus Christ (vv. 1-4).
Jude recalls three examples: the Lord who saved a people out of Egypt afterward destroyed those who did not believe; the angels who left their proper domain are kept in eternal chains for the judgment of the great day; and Sodom and Gomorrah, which indulged in immorality, suffer the punishment of eternal fire. Likewise these dreamers defile the flesh, reject authority and blaspheme the glorious ones. Even the archangel Michael, contending with the devil about the body of Moses, did not presume to pronounce a railing judgment, but said: The Lord rebuke you (vv. 5-10).
Woe to them! They walked in the way of Cain, rushed for profit into Balaam's error and perished in Korah's rebellion. They are blemishes on your love feasts, self-feeding shepherds, waterless clouds and wandering stars. Enoch, the seventh from Adam, prophesied that the Lord will come with his holy ones to execute judgment on all the ungodly. They are grumblers who flatter for advantage (vv. 11-16).
The apostles predicted scoffers who cause divisions. The beloved are to build themselves up in their most holy faith, pray in the Holy Spirit, keep themselves in the love of God, wait for the mercy of Jesus Christ that leads to eternal life and have mercy on those who doubt. He ends with a doxology: to him who is able to keep them from stumbling and present them blameless with great joy, the only God our Savior, be glory, majesty, dominion and authority (vv. 17-25).
