Ephesians 5:3 Meaning: The Sin That Shouldn’t Even Be Named

Three Greek words stand out here. Porneia is the root of our word “pornography,” but it covers any sexual sin: adultery, prostitution, everything outside of God’s design. Akatharsia means “uncleanness” in a moral sense, thoughts, words, or actions that stain a life meant to be pure. And pleonexia is usually translated “covetousness” but means literally “a desire to have more.” Several early commentators noted it could mean an insatiable appetite for pleasure or for money. Paul sees these as cut from the same cloth: both try to fill a God-sized hole with something that will never satisfy. Then he uses the verb onomazesthō, “let it not even be named.” This isn’t about silence; it’s about absence. These things should be so foreign to your life that there is no occasion even to speak of them among you.

Christian readers have long wrestled with Paul’s pairing of sexual sin and covetousness. Some, like John Calvin and the Geneva Bible, see covetousness as a greed for possessions, which the apostle elsewhere calls idolatry. Others, citing the way Paul uses “covetousness” in 4:19, understand it as an insatiable hunger for sensual gratification, a form of lust that never gets enough. The Cambridge Bible notes that the Greek word pleonexia had acquired a link to sensual greed by Paul’s time. Both readings agree: the sin is a grasping, discontent heart that refuses to trust God. The command “let it not even be named” has been taken as a call to avoid even the appearance of evil, so that no one among the saints has reason to gossip about such behavior.

A common misunderstanding is that “let it not even be named among you” means Christians must never talk about sexual sin or greed, that even mentioning them is wrong. In fact, Paul himself names them here, and he does so throughout his letters. He means these sins should be so absent from the church’s life that there’s no occasion to say, “I heard that so-and-so did such-and-such.” The goal is not silence about sin, but holiness that makes such conversations unnecessary.

This week, pay attention to what you let yourself want. Covetousness often hides in plain sight: scrolling homes you wish were yours, nursing resentment that someone else got the promotion, daydreaming about a relationship that isn’t yours. Paul says treat that inner grasping the same way you treat a glaring sexual sin, as something that doesn’t belong in a life set apart for God. When you feel that pull to want more, stop and hand it to God. Ask Him to shape your desires until what you want matches what He wants for you. That is walking as a saint.
