2 Beware of dogs, beware of evil workers, beware of the mutilation! 3 For we are the circumcision, who worship God in the Spirit, rejoice in Christ Jesus, and have no confidence in the flesh (Philippians 3:2–3, NKJV)
Christ’s apostle boldly described those who perverted the gospel (i.e., false brethren) by demanding Gentiles keep the law of Moses to be saved; They were false brethren (Acts 15:5; Gal. 2:4-5; 5:4). For emphasis, Paul gave one warning three times. (1) Beware of dogs (v. 2). Feral dogs lived in packs, scavenging for food (Ps. 59:6; 1 Kings 14:11). We must be alert against false teachers who attack and consume souls (Gal. 1:6-10; Jude 4). (2) Beware of evil workers (v. 2). Their works are wicked; Do not give them quarter (Ps. 119:115; Phil. 2:18-19). (3) Beware of the mutilation (v. 2). The doctrine of binding circumcision for salvation did nothing to remove sin because it was only a physical incision. By contrast, Christians (whether Jews or Gentiles) are “the circumcision” (the covenant people of God, whose hearts are circumcised, Rom. 2:28-29; Col. 2:11-13). Next, Paul gave three counterbalancing descriptions of Christians. (1) Christians worship God in the Spirit (v. 3). The word “worship” denotes service to God. We serve God according to the truth that the Spirit revealed, not by the error of the “dogs” (Gal. 3:1-3; 5:5-6). (2) Christians rejoice in Christ Jesus (v. 3). We have joy in Christ and do not take pleasure in evil things (Phil. 3:1; 4:4; Rom. 12:15). (3) Christians have no confidence in the flesh (v. 3). Our salvation in Christ does not depend on physical pedigree, performance, and promotion. Paul refused to trust in such things (Phil. 3:4-7). Brethren, be alert to error and those who teach it. Serve God with the confidence of the truth of the gospel.
