Topical Lexicon
Concept and Meaning

Strong’s Greek 2636 (katalalia) denotes malicious talk that tears down another’s reputation. While gossip may pass along information carelessly, katalalia is intentional defamation—speech aimed at diminishing, discrediting, or destroying someone in the eyes of others. Scripture consistently treats it as a moral evil springing from a heart at odds with the character of God, whose own speech is always true, gracious, and life-giving.

Occurrences in the New Testament

2 Corinthians 12:20 lists katalaliai among a cluster of relational sins threatening the Corinthian fellowship. Paul fears he will find “strife, jealousy, rage, rivalries, slander, gossip, arrogance, and disorder” when he arrives. The term stands in sharp contrast to the humility and edification that should mark believers.

1 Peter 2:1 exhorts born-again readers to “rid yourselves of all malice, deceit, hypocrisy, envy, and slander”. Positioned immediately before the call to “crave pure spiritual milk,” katalalia functions as a toxic contaminant that must be abandoned if spiritual growth is to proceed.

Though the noun appears only twice, its theological weight is carried further by related verbs (katalaleō, “speak against”) and by wider biblical teaching on the tongue.

Historical and Cultural Setting

In Greco-Roman society, honor and reputation were currency. Public defamation could damage social standing, business prospects, and legal outcomes. Jewish communities likewise regarded a good name (Proverbs 22:1) as precious. Therefore the early churches would have understood katalalia not as a harmless vice but as a community-destroying assault.

Theological Significance

1. An Assault on the Image of God

Slander devalues the divine image in others (Genesis 1:26-27). Speaking evil of a brother or sister is indirectly speaking against God who made and redeemed them.

2. Opposition to Christ’s Law of Love

Jesus summed up the moral law as loving God and neighbor (Matthew 22:37-40). Katalalia violates this love, placing personal pride or bitterness above the welfare of another.

3. Evidence of Fleshly Living

Paul lists slander among the “works of the flesh” (cf. Galatians 5:20; Colossians 3:8). Its presence signals areas where the Spirit’s sanctifying work is being resisted.

4. A Threat to Church Unity and Witness

Early congregations were small, close-knit, and highly visible within hostile cultures. Slander could fracture fellowship, ruin elders’ credibility, and give the surrounding world grounds to blaspheme (cf. Titus 2:5).

Practical Ministry Implications

• Pastoral Oversight

Shepherds must guard flocks from tongue-based divisions. Matthew 18:15-17 outlines restorative confrontation that replaces back-biting with face-to-face truth spoken in love.

• Discipline and Restoration

Because katalalia is relationally corrosive, churches historically have treated persistent slander as a disciplinable offense, always aiming at repentance and reconciliation (2 Corinthians 2:6-8).

• Teaching the Positive Counterpart

Scripture does not merely forbid evil speech; it prescribes edifying speech (Ephesians 4:29), thanksgiving (Colossians 3:16), and gracious words seasoned with salt (Colossians 4:6). Replacing katalalia with encouragement is part of putting on the “new self.”

• Safeguarding Leadership

Elders and deacons must be “above reproach” (1 Timothy 3:2, 10). Unfounded accusations can unravel ministry. Careful procedures ensure that legitimate concerns are heard while malicious rumors are stopped (1 Timothy 5:19).

Warnings and Consequences

• Divine Judgment

Psalm 101:5 warns, “Whoever slanders his neighbor in secret, I will put to silence.” God defends the oppressed and will hold slanderers accountable.

• Self-Destructive Outcomes

Proverbs 10:18 teaches that slanderers are fools; their own credibility erodes. James 4:11-12 equates speaking against a brother with judging the law itself, bringing the speaker under God’s judgment.

• Hindrance to Prayer and Worship

Jesus instructs worshipers to reconcile with offended brothers before offering gifts at the altar (Matthew 5:23-24). Unconfessed katalalia clogs the believer’s communion with God.

Pathways to Redemption

• Heart Surgery by the Word

1 Peter 2:2 connects putting off katalalia with longing for the word that nourishes growth. Scripture renews inner motives, not merely outer vocabulary.

• The Spirit’s Control

Only the Holy Spirit can tame the tongue (James 3:8). Yielding daily to His influence produces speech marked by love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control.

• Practicing Confession and Apology

James 5:16 urges believers to “confess your sins to one another.” Owning slanderous words, seeking forgiveness, and making restitution restores fellowship.

Related Biblical Themes

• Gossip (psithurismos) – secret whispering that entertains rather than fabricates.
• Reviling (loidoros) – open verbal abuse.
• False witness – legal perjury, forbidden in the Decalogue.
• Blessing vs. cursing – Romans 12:14; 1 Peter 3:9.

Conclusion

Katalalia is a potent enemy of unity, holiness, and witness. Though appearing only twice by name, its destructive potential echoes through both testaments. The gospel offers both cleansing from past slanders and power to replace venomous speech with words that build up, reflect Christ’s character, and glorify the God whose truth endures forever.
