[This is being written by] Jude, a slave of Jesus Christ, and a brother of James [Note: This "Jude" was probably not the apostle. See verses 17-18], to those who have been called [by God], who are also loved in [fellowship with] God the Father, and who are kept [safe] in [fellowship with] Jesus Christ.

For certain men have secretly infiltrated [your ranks]; they are men who had been written about long ago that they should be judged [and condemned] for perverting the unearned favor of our God into [a license for] living unrestrained, indecent lives, and who deny [the identity and work of] our only Master and Lord, Jesus Christ.

These people are like rotten spots [contaminating the food] at your love feasts, while they gorge themselves without fear [i.e., unashamed of their selfish indulgence]. [Note: This passage may mean "like selfish shepherds, looking out only for themselves, they eat the grain set out for the animals"]. They are like clouds that blow over without producing rain; [they are like] trees in the fall that do not produce any fruit and have been uprooted, [thus] being dead twice [i.e., fruitless and rootless].

[They are like] raging ocean waves, whose shameful actions bubble up like foam. [They are like] shooting stars [whose light quickly goes out], for whom total darkness has been reserved forever.

These people are gripers and complainers, living according to their own [evil] desires, whose mouths speak boastfully, and who show partiality [toward certain people] to gain some advantage.

These are people who cause divisions [among God's people]; they follow their natural inclinations [i.e., worldly principles], for they do not have the Holy Spirit [in their lives].
