Romans 12:9 Commentary: Sincere Love

Paul writes Romans to a church he had not yet visited, a community of Jewish and Gentile believers in the imperial capital. The letter’s first eleven chapters lay out God’s plan of salvation; chapter 12 marks a turn to practical ethics. In verses 3, 8, Paul has described gifts of the Spirit, from prophecy to giving to mercy. Then, beginning at verse 9, he shifts to the character that must animate every gift: sincere love.

The flow from verse 8 to 9 is abrupt. Some commentators (e.g., Lange) see verse 9 as a kind of heading or 'inscription' over the whole list of participles that follow through verse 21. The participles in Greek (abhorring, cleaving, rejoicing, weeping, etc.) function as imperatives; the Cambridge Bible notes they 'stand for hortative verbs' and 'describe in order to set a standard for endeavour.'

The call to 'abhor that which is evil' echoes Old Testament wisdom. Psalm 97:10 says 'You who love Yahweh, hate evil!' And Psalm 34:14: 'Depart from evil, and do good. Seek peace, and pursue it.' The intensity of Paul's language, apostugeō, suggests a visceral turning away from evil, not a mild disapproval. This would have resonated with a church that faced both internal tensions (Jewish, Gentile friction) and external pressures from a pagan culture where hypocrisy and flattery were social currency. The story of Joab's kiss (2 Samuel 20:9, 10) stands as a dark warning: a greeting can hide a sword.

By contrast, 'cling to that which is good' uses kollaō, the word for being glued or cemented. In a world without superglue, the image is of two surfaces pressed together so firmly they become one. The focus is on community: Paul has just finished describing how believers are 'one body in Christ' (v.5). The good to which they cling includes service to the saints and hospitality, the very activities listed in the verses just after verse 9.

The consulted sources note no significant textual variants for Romans 12:9. The Greek text is stable across the major manuscript families, and no alternative readings alter the meaning of the verse.

Romans 12:9 has been a staple in Christian ethical instruction across traditions. Early church fathers such as Chrysostom commented on the need for love without hypocrisy, linking it to the pure love of God. During the Reformation, this verse served as a concise summary of Christian sincerity; Calvin and Luther both used it to argue that true faith produces genuine love, not merely outward compliance. In the Wesleyan tradition, it has been cited alongside the call to entire sanctification, as the believer’s affections are reoriented, hating sin and loving goodness. Modern evangelical preaching often points to the verse as a moral compass: real love does not ignore evil but confronts it while actively embracing good. In Catholic teaching, it is read as part of the ‘new law of love’ that fulfills the commandments, and in Orthodox spirituality it appears in the context of the purification of the heart through the struggle against the passions. The verse continues to be used in catechesis, small group studies, and as a prayer for sincerity in relationships.

Three-point outline

1. Love without a mask. Paul begins with the absolute necessity of sincerity. The word anupokritos (unhypocritical) comes from the stage, an actor playing a part. Christian love is not a performance. It must match inner reality with outward action.
2. Hatred that is holy. The command to 'abhor evil' uses a rare, intensified verb. This is not a cool avoidance; it is turning away with loathing. That intensity is reserved for evil, not for people.
3. Glued to the good. The word for 'cleave' means to be cemented together. Genuine love does not merely tolerate what is good; it attaches itself with lasting, durable commitment, to God, to Christ, to fellow believers, to acts of kindness.

Five-point outline

1. Sincere love as the foundation of all Christian ethics (v.9a).
2. The negative half of turning from evil (v.9b), a holy abhorrence.
3. The positive half of cleaving to good (v.9c), an active, glue-like attachment.
4. Brotherly affection as the first expression of that cleaving (v.10), preferring others in honor.
5. Diligent service flowing from love (vv.11-13), fervent in spirit, serving the Lord, sharing with saints.

Illustration hooks

• A wedding ring: meant to signify a lifelong, exclusive commitment. When a spouse acts loving in public but is cold at home, that is hypocrisy. Real love shows the same face in every setting.
• A surgeon's scalpel: a good tool used for healing, but in the same moment it cuts away what is diseased. Christian love both removes evil and repairs what is broken.
• Glue that has set: think of two pieces of wood bonded so firmly that they cannot be pried apart without damage. That is the kind of attachment Paul calls for, not a loose association, but a permanent union with what is good.

Questions your congregation is asking

• Is it okay to hate anything as a Christian? The verse says 'abhor evil', how do I distinguish hating evil from hating people?
• How can I tell if my love is sincere or just polite? What are the signs of hypocrisy I should watch for?
• What does 'the good' look like in daily life? Is it just avoiding sin, or is there a positive action I'm supposed to cling to?

Romans 12:9 comes as a turning point in Paul's letter. After eleven chapters of theology and a picture of the church as a body with diverse gifts, Paul now gives a series of short, punchy commands. This verse is the doorway: love must be real, not a mask. And real love has two hands, one to push away evil, one to hold tight to good.

Discussion questions

1. Read Romans 12:9 aloud in two or three different translations. What words stand out to you in each one?
2. The word translated 'hypocrisy' comes from the Greek for actors. In what situations are Christians most tempted to 'perform' love rather than actually feel and show it?
3. Paul uses a very strong verb for 'abhor', it means to hate with horror. Why do you think he chooses such a powerful word? Is there a difference between hating evil and hating people who do evil?
4. What does 'cling to what is good' look like in your daily routine? Can you think of a specific 'good' thing, a person, a practice, a truth, that you need to glue yourself to more firmly?
5. Verses 10, 13 expand on this verse. How does 'preferring one another' or 'hospitality' help you understand what 'good' Paul has in mind?
6. Some commentators think 'evil' here refers specifically to malice or unkindness toward others (see Calvin, Barnes). Others take it as evil in general. Which reading seems more natural to you from the context, and why does it matter?
7. Think of a time when you experienced love that felt truly sincere, from someone else or from yourself. What made it sincere? How could your group encourage that kind of love in one another?
