Rejoice in the Lord: The True Circumcision
Paul’s repeated call to rejoice is abruptly joined to a triple warning: beware of dogs, evil workers, and “the concision.” The last term is a sharp wordplay on circumcision—Paul contrasts mutilation with the covenant identity he describes in verse 3. “We are the circumcision,” he says of those who worship by the Spirit, glory in Christ Jesus, and refuse confidence in the flesh.
Where this fits in the story: circumcision begins as Abraham’s covenant sign in Genesis 17, but Israel’s own Scriptures already push beyond the outward sign toward the heart. Deuteronomy 30:6 promises that the LORD will circumcise the heart, while Jeremiah 4:4 commands Judah to “circumcise” the heart in repentance. Paul’s argument therefore does not invent inward covenant language from nowhere. Romans and Colossians develop the same trajectory: bodily circumcision cannot replace the inward work of God or become a basis for boasting before him.
