Ephesians 4:25 Commentary: Truth and the Body of Christ

Paul’s readers in Ephesus had come from a pagan culture where lying was widely accepted and even praised. Adam Clarke cites Greek poets and philosophers who taught that a lie was preferable to a hurtful truth, and that profit justified deception. Barnes notes that lying was “the universal vice of the pagan world,” and that converted pagans needed a new conscience about truthfulness, old habits died slowly. The apostle’s command therefore addressed a concrete struggle: how to live as the new man (Eph 4:24) in a society that saw deception as normal.

Paul draws on the Old Testament background. Leviticus 19:11 commands, “You shall not lie; you shall not deceive one another.” Zechariah 8:16 calls for truth in judgment. The Jewish tradition valued truth as a foundation of community, but many of Paul’s readers would not have been raised in that tradition. By quoting the prophecy with a twist, Paul links the Christian community to the eschatological hope of a holy people.

The phrase “members one of another” echoes the body metaphor already established in 1 Corinthians 12. In a Roman world where patronage and status shaped relationships, Paul insists that believers share a mutual belonging deeper than social ties. Lying fractures this bond; truth sustains it. The cultural pressure to exaggerate, flatter, or conceal for personal gain was as strong then as now. Paul’s instruction is not idealistic but necessary for the health of a community that claims to be united in Christ.

The consulted sources note no significant textual variants for Ephesians 4:25. The Greek text is well established across manuscripts, with only minor variations in word order (e.g., λαλεῖτε ἀλήθειαν vs. ἀλήθειαν λαλεῖτε) that do not affect meaning. Paul’s quotation of Zechariah 8:16 follows the Septuagint but adapts the preposition for theological emphasis.

In the early church, Chrysostom used the image of the eye and foot to illustrate how truth protects the body. His homilies on Ephesians stressed that lying destroys the mutual trust essential to Christian fellowship. During the Reformation, Calvin and the Geneva Bible emphasized that truthfulness flows from the new self created in true holiness, not from mere moral effort. Puritans like Matthew Henry applied the verse to everyday life, warning against commercial deceit and flattery. In modern missions, Barnes and the Cambridge Bible connected the command to the challenge of building honest communities in cultures where lying was routine. Across traditions, this verse has been a staple in ethical catechesis, reminding believers that their speech reflects their union with Christ and with each other.

Three-Point Outline

1. The Old Self Left Behind: “Putting away falsehood” (aorist participle) means a decisive break with the lie that once shaped our lives. The new man created in true righteousness cannot coexist with deceit (v. 24).
2. The Positive Call to Truth: “Speak truth each one with his neighbor.” Truth is not merely the absence of lies; it is active, relational integrity that builds the community.
3. The Foundation of Unity: “For we are members one of another.” Our union in Christ makes deception a form of self-harm, lying to a brother or sister is lying to ourselves.

Five-Point Outline

1. Wherefore: The connection to the new self (v. 22, 24). Truthfulness flows from our new identity.
2. Putting away lying: The aorist participle implies a past decision that must be lived out daily.
3. Speak truth: The present imperative “do speak” calls for consistent, ongoing honesty.
4. With his neighbor: The scope includes every fellow believer, but extends through them to all people.
5. For we are members one of another: The reason that transforms ethics into mutual care.

Illustration Hooks

• The double-edged tongue: A witness in court who speaks truth under oath but lies to a friend at lunch. Paul asks: why would we treat a brother or sister worse than a courtroom?
• The hidden cost of a ‘small’ lie: A church member who exaggerates his prayer life to sound spiritual. It seems minor, but over time it erodes trust until no one knows what is real.
• Chrysostom’s analogy: The eye and the foot crossing a hidden pit. If the eye signals safety when the ground is weak, the whole body falls. Truth is survival.

Questions Your Congregation Is Asking

• Is it ever okay to lie to protect someone’s feelings or to avoid conflict?
• How do I repent of habitual exaggeration or “white lies” without becoming obsessed?
• What should I do when I discover a leader in the church has been dishonest?

This verse is a practical test of our new identity in Christ. Truthfulness is not just a moral rule but a vital sign of the new self. As you discuss, keep the focus on how our unity in Christ changes the way we speak to one another.

Discussion Questions

1. Read Ephesians 4:22, 24. How does the command to “put away falsehood” connect to putting off the old man and putting on the new?
2. Paul uses an aorist participle (“having put away”). Why does the timing of our break with lying matter for daily obedience?
3. The word for “falsehood” is abstract (τὸ ψεῦδος, the lie). How does this broaden the command beyond telling outright lies?
4. What does it mean that we are “members one of another”? How would Chrysostom’s eye-and-foot illustration change the way you speak?
5. Barnes lists several modern forms of lying (in trade, turning away visitors, coloring narratives). Which of these do you find most common in your own context?
6. How does the promise “we are members of one another” make honest speech not just a duty but a gift to the community?
7. What step can you take this week to speak the truth in love to someone you normally avoid or flatter?
