Porque ni aun los mismos que se circuncidan guardan la ley; sino que quieren que vosotros seáis circuncidados, para gloriarse en vuestra carne.
Pois nem mesmo os que se circuncidam guardam a Lei; mas querem que vos circuncideis, para se orgulharem de vossa carne.
Car les circoncis eux-mêmes n’ observent point la loi; mais ils veulent que vous soyez circoncis, pour se glorifier dans votre chair.
Denn auch sie selbst, die sich beschneiden lassen, halten das Gesetz nicht; sondern sie wollen, daß ihr euch beschneiden lasset, auf daß sie sich von eurem Fleisch rühmen mögen.
Want ook zijzelven, die besneden worden, houden de wet niet; maar zij willen, dat gij besneden wordt, opdat zij in uw vlees roemen zouden.
Poiché neppur quelli stessi che son circoncisi, osservano la legge; ma vogliono che siate circoncisi per potersi gloriare della vostra carne.
Albowiem i ci, którzy się obrzezują, nie zachowywują zakonu sami, ale chcą, abyście się wy obrzezali, żeby się z ciała waszego chlubili.
ибо и сами обрезывающиеся не соблюдают закона, но хотят, чтобы вы обрезывались, дабы похвалиться в вашей плоти.
他們 那些受割禮的，連自己也不 守 律法； 他們願意 你們 受割禮，不過要 藉著 你們 的肉體 誇口。
Because even those who undergo circumcision do not themselves keep the law; but they would have you undergo circumcision, so that they may have glory in your flesh.

Scholars' Consensus
Commentators agree that Paul charges the Judaizing teachers with hypocrisy and self-interest. The phrase “those who receive circumcision” refers to the false teachers actively promoting the rite, not all circumcised Jews (Calvin, Cambridge). Barnes notes that no one perfectly keeps the law, but these teachers selectively enforce circumcision while ignoring weightier matters (Matt 23:23). Vincent points to the present participle peritemnomenoi, “those being circumcised”, showing their current activity in pressing the rite on others. Their failure to keep the law is not just a moral shortcoming; it exposes that their zeal has nothing to do with obedience. Their real aim is to boast in the Galatians' flesh. Clarke explains they want to say, “Behold my converts!” The Cambridge Bible calls it a “party triumph.” The consensus is clear: the teachers are driven by pride, not piety, and Paul will respond by boasting only in the cross (v.14).
How settled is the interpretation?
Interpretive difficulty: Medium
Main views:
- Hypocrisy view: The teachers consciously ignore the law despite preaching it (Barnes, Calvin, Gill).
- Inconsistency view: They are inconsistent by picking one ritual while neglecting others (Matthew Henry, Cambridge).
- Cultural badge view: They promote circumcision as a social identifier to avoid persecution (Poole, historical reading).
What is clear: The teachers' primary motivation is self-glory in external conformity, not genuine love for God or the Galatians.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| Who are 'those who receive circumcision'? | Refers to the Judaizing teachers who promote circumcision in Galatia. | Some commentators (e.g., Barnes) include all Jews generally, while others (Calvin, Cambridge) limit it to the teachers themselves. |
| What does 'keep the law' mean here? | The teachers fail to fully obey the law, whether by neglecting key parts or by not living up to its demands. | Is Paul saying that no one can perfectly obey the law (general human inability, Barnes, Cambridge), or that these teachers are deliberately inconsistent and insincere (Calvin, Gill)? |
| What is 'boast in your flesh'? | The teachers want to glory in the Galatians' external submission to circumcision. | Is the boast about the converts themselves (Matt 23:15 parallel, Clarke) or about the teachers' own zeal? Both are present. |
| Why are the teachers doing this? | They want to avoid persecution and gain status among Jews. | Whether the persecution they fear comes from Jews or from Roman authorities? Poole notes Roman tolerance for Jews, so circumcision provides a safe cover. |
Historical & Cultural Context
When Paul writes this closing section of Galatians, he is speaking into a intense conflict. False teachers, often called Judaizers, have entered his churches in Galatia, insisting that Gentile believers must be circumcised to be truly saved. Paul has already argued at length that the law cannot justify; only faith in Christ does. Now he exposes what is really driving the teachers.
At that time, the Jewish religion enjoyed legal recognition from Rome, while the Christian movement occupied a more exposed position. By requiring circumcision, the Judaizers could claim that their converts were proselytes to Judaism, thereby sidestepping persecution (Poole). The teachers wanted to “make a good impression in the flesh” (v.12) to avoid the social cost of identifying fully with the cross. Boasting in the Galatians' flesh meant they could point to tangible, visible results and gain status among their own people. Jesus had already condemned this pattern: “you travel around by sea and land to make one proselyte” (Matt 23:15). The Galatians were being treated as trophies, not as children of God.
This historical pressure explains why the teachers clung so fiercely to circumcision. It was not theological conviction but a blend of self-preservation and vanity. Paul, by contrast, will end by showing the scars of his own suffering for Christ (v.17). The cross, not the knife, is what marks true belonging.
Textual Notes
The supplied sources mention a minor variant in the participle: the present περιτεμνόμενοι (being circumcised) versus the perfect περιτετμημένοι (having been circumcised) in some manuscripts. Gill references the perfect reading, which appears in the Textus Receptus. The present participle emphasizes ongoing activity, they are currently being circumcised and actively promoting the rite. The perfect would describe a state. The difference does not affect the core meaning: these are people who have received the rite and insist on it for others. The consulted sources agree that no significant textual variant alters the interpretation.
Reception History
Augustine used this verse to argue that the law cannot justify, since even its advocates fail to keep it. The Reformers, especially Luther, applied it to hypocrisy in the medieval church, those who demanded works while not fulfilling them. Calvin drew a parallel to the “courtly apostles” of his own day, men who defended church authority for personal gain. In the Wesleyan tradition, the verse warns against using outward religion as a cover for a lack of inner transformation. Across traditions, Galatians 6:13 has been a mirror for religious leadership, calling leaders to examine whether they labor for Christ’s fame or their own.
Preaching This Verse
Three-point outline
- Inconsistency exposed. The Judaizers demand circumcision but cannot keep the law themselves. Their teaching is not backed by practice. This is a warning: our lives must match our message, or our words lose all force.
- Hidden motive revealed. Their real aim is to boast in the Galatians' flesh. Religious activity can become a performance for human approval. Paul cuts through the excuse to expose the heart.
- The cross-centered alternative. Paul contrasts their boasting with his own: “May I never boast except in the cross” (v.14). The only ground for confidence is Christ's work, not our achievements or our converts.
Five-point outline
- The teachers' target: the Galatians' bodies (circumcision).
- Their failure: they do not keep the law themselves.
- Their motive: to avoid persecution and gain status.
- Their prize: boasting in your flesh, making you a trophy.
- Their contrast: Paul's boasting in the cross and the new creation.
Illustration hooks

- In what ways might Christians today “boast in the flesh” of others, through numbers, conversions, or visible achievements?
- How does Paul's own boasting in the cross (v.14) provide a model for our attitude?
- How can we guard against the desire to use others for our own glory?
- What would it look like for your group to celebrate spiritual growth without making it about human accomplishment?

What the Commentators Say
10 public-domain commentaries, condensed into plain language.
Adam Clarke's Commentary Methodist/Wesleyan 1826
Clarke points out that the false teachers promoted circumcision not out of devotion to God’s will, but because it gave them a reason to boast. They wanted to say, “Look at my converts!” — not thrilled that people were turned to God, only that they were circumcised. Their pride was in the flesh, not in the Spirit.
Barnes' Notes on the Bible Protestant 1832
Barnes highlights the inconsistency of the Judaizing teachers: they demanded circumcision from others but did not keep the whole law themselves. Their real motive was to boast in their converts' circumcision, using it to display their own zeal and avoid persecution. This, for Barnes, reveals their hypocrisy.
Calvin's Commentaries Reformed 1564
Calvin specifies that Paul directs his charge at the teachers who insist on circumcision, not at every circumcised person. Their real fault is insincerity: they enforce the law on others but ignore it themselves whenever it suits them. Calvin compares them to his own era's church leaders who demand obedience to Rome's decrees while personally disregarding them.
Cambridge Bible for Schools and Colleges Anglican 1880
The commentator argues that Paul's accusation is based on a moral impossibility, not practical difficulties: fallen human nature makes it impossible for anyone, including the Judaizers themselves, to fully keep the Law. Their real motive is party triumph, not salvation. "Glory in your flesh" means boasting in mere outward compliance with an ordinance.
Geneva Bible Notes Reformed 1599
The Geneva Notes point out that the teachers pushing circumcision do not keep the law themselves. Their real motive is pride: they want to boast in the Galatians' outward, fleshly compliance as a mark of their own success.
Gill's Exposition of the Bible Baptist 1748
Gill argues that those pushing circumcision do not actually keep the law themselves; their real aim is to boast to fellow Jews about how many converts they have won. Even if they kept the ritual, no one can fully obey the whole law, so circumcision cannot bring righteousness or salvation. Their zeal serves self-glory, not godliness.
Jamieson-Fausset-Brown Commentary Protestant 1871
JFB notes that those pushing circumcision do not actually keep the law themselves. They single out this one ritual as if it can substitute for obedience to the whole law. Their real motive is to boast in the outward change they have produced in you, not in any inward work of the Spirit.
Matthew Henry's Commentary Reformed/Presbyterian 1710
Henry notes that Paul personally wrote this long letter as a special mark of his affection, unlike his usual practice of dictating. Paul then contrasts the false teachers, who push circumcision only to avoid persecution and boast in outward religion, with his own determination to boast only in the cross of Christ.
Vincent's Word Studies Evangelical 1887
Vincent observes that Paul's present tense "those who are receiving circumcision" highlights an active party, not a fixed group of Jews. They aggressively push circumcision on others even though they cannot keep the law themselves. Their motive is fleshly: they want to boast in the Galatians' outward conformity, not in genuine moral obedience.
Wesley's Explanatory Notes Methodist/Wesleyan 1754
Wesley points out the hypocrisy of those demanding circumcision: they themselves do not keep the whole law, yet they insist others be circumcised. Their real motive is to boast about making converts and to gain credit with other Jews, not out of genuine zeal for God's law.
