But among you, as is proper among the saints, there must not be even a hint of sexual immorality, or of any kind of impurity, or of greed.
The apostle names three vices so abhorrent that Christians must not even speak of them: fornication, all base and impure lusts, and covetous greed. To demand this of you is nothing unusual, it befits the saints, and Paul plainly excludes fornicators, the impure, and the covetous from the fellowship of the holy altogether.
AI summary
Fornication between unmarried persons exposes men to divine wrath and shuts them from heaven without repentance. Uncleanness covers adultery, incest, sodomy, every unnatural appetite. Covetousness here means greedy insatiable lust for these very things. None of it should exist among you, much less be named with pleasure, you are sanctified by God's Spirit and Christ's blood.
AI summary
The Greek runs stronger: let these things not even be named. Uncleanness and covetousness both work from the same root, a longing to fill desire with material objects of sense, outside of God. The prohibition bites hardest on impurity, yet both sins belong to the same degraded appetite for what lies beneath Him.
