Colossians 3:5 Commentary: Killing Sin and the Idolatry of Greed

Paul writes to a young church in Colossae, a city in Asia Minor known for its ethnic and religious mixture. The letter confronts a “philosophy” (Col 2:8) that combined Jewish legalism, angelic worship, and ascetic rules. Some teachers promoted self-denial through physical disciplines (Col 2:20, 23), yet Paul insists that true mortification is not external abstinence but the inner killing of sin by the power of Christ’s death and resurrection.

Verse 5 stands in a long tradition of early Christian ethical catalogues (see Romans 1:29, 31; Ephesians 5:3, 5). Such lists adapted Jewish vice-lists to the Greco-Roman setting, where sexual immorality (πορνεία) encompassed all forms of illicit intercourse, often tolerated in pagan worship. “Uncleanness” (ἀκαθαρσία) pointed to moral impurity in thought and deed. “Passion” (πάθος) and “evil desire” (ἐπιθυμία κακή) cover the inner disorder of affections that lead to outward sin.

The final item, “covetousness” (πλεονεξία), literally means “having more.” In a culture dominated by patronage, status-seeking, and material accumulation, Paul’s equation of greed with idolatry was radical. As Calvin and Clarke note, the covetous person transfers trust and devotion from God to wealth, making money the functional god. The placement of this sin at the end of the list, with a definite article marking it as a distinct category (Jamieson-Fausset-Brown), shows Paul’s pastoral concern: earthly members include not only obvious bodily sins but the sophisticated sin of the heart that loves things over the Creator.

The historical setting thus sharpens the command: in a world of competing allegiances, believers who have died with Christ must repudiate every loyalty, whether fleshly, craving, or acquisitive, that contradicts their union with him.

The Greek text of Colossians 3:5 is stable across the major Alexandrian and Western manuscript traditions. No significant textual variants are noted by the consulted commentaries. The word order is uniform, and the vice list appears in the same sequence in all early witnesses. The modern critical editions (NA/UBS) show no variation in the verb νεκρωσατε or the nouns listed. The only minor point is that some later manuscripts insert the article before επιθυμιαν, but this does not affect meaning.

Colossians 3:5 has been a cornerstone of Christian teaching on sanctification and the mortification of sin. In the patristic period, the verse was used in catechetical instruction to renounce the vices of pagan culture; John Chrysostom preached that Paul ’calls the vices members because they cleave to us like members.’ The equation of covetousness with idolatry became a recurring theme in medieval moral theology and in the Reformation, where Luther and Calvin warned that greed was not merely a social sin but a religious offense. In Puritan devotional literature, this verse was mined for its practical advice on how to ‘kill sin’ daily. In modern evangelicalism, the verse is often cited in calls for sexual purity and in critiques of consumerism. Across traditions, the passage is recognized as a summons to a radical, Spirit-empowered break with sin that flows from union with Christ.

Three-point outline

1. The Foundation: Because you have died with Christ (Col 3:3) and your life is hidden in him, you have both the obligation and the power to put sin to death.
2. The Command: “Put to death therefore your members which are on the earth”, a decisive, aorist act of renunciation applied to sexual sins and selfish desires alike.
3. The Climax: Covetousness is idolatry. Greed is not a small failure; it is treason against God’s exclusive claim on the heart.

Five-point outline

1. The indicative precedes the imperative: what God has done (raised us with Christ) grounds what we must do (mortify sin).
2. The aorist imperative calls for a clear break, not a half-measure. “Kill at once” (Lange’s paraphrase).
3. The list refuses any division between “spiritual” and “physical” sins: sexual impurity and greed both belong to the old life.
4. Covetousness is singled out because it mimics worship. It gives the heart’s devotion to a god of silver and gold.
5. The wrath of God (Col 3:6) underscores the gravity: the “children of disobedience” live in these sins; believers must not.

Illustration hooks

• Think of a cancer patient who submits to chemotherapy. The treatment is violent but life-saving. Letting sin live is like refusing treatment because it hurts.
• When a gardener sees a weed with deep roots, she must pull it out from the root, not just snip the leaves. Mortification means getting at the root of desire.
• Covetousness as idolatry: imagine someone who spends every waking hour curating a collection of rare teapots. That collection has become their temple, their source of worth. Greed works the same way with money.

Questions your congregation is asking

• If I’m already “dead to sin” (Rom 6:11), why do I still have to fight it so hard?
• How do I know if my desire for something has crossed into idolatry?
• Is it enough to stop doing the sin, or do I need to change what I want?

This verse stands at the hinge of Paul’s teaching on Christian living. After declaring that believers have died with Christ and have a hidden life in him, he calls for a decisive act: put to death the sinful patterns that still cling to earthly existence. The list moves from sexual sins to the inner attitude of greed, which Paul dares to call idolatry. As you work through the questions, pay attention to the tension between “already dead” and “still needing to kill.” That tension is the heartbeat of the Christian life.

Discussion questions

1. Observation: What five or six specific sins does Paul tell the Colossians to put to death? How does he organize them?
2. Observation: The Greek verb νεκρωσατε is an aorist imperative. Why is that detail important? What difference does “decisive action” make compared to “try to do better”?
3. Interpretation: Why does Paul connect “covetousness” directly with “idolatry”? What makes greed a form of false worship?
4. Interpretation: How does the phrase “your members which are on the earth” relate to Colossians 3:1, 4? What is the contrast between “things above” and “on the earth”?
5. Interpretation: Some Christians read “put to death” as a one-time event; others see it as a daily discipline. How do both perspectives fit with the grammar and the rest of the New Testament (e.g., Romans 8:13)?
6. Application: What would it look like this week to “kill” a specific sinful habit rather than just manage it?
7. Application: How can the local church help members identify and turn from the idolatry of greed without becoming legalistic about money?
