2. THE EXAMPLE TO BE AVOIDED (3:2–3)One particular group in Paul’s day was especially guilty of putting confidence in the flesh. These were the Judaizers. They plagued Paul and his converts constantly. Confused about the gospel, they added works of the law to faith in Christ, both for salvation and for Christian living. The Old Testament rite of circumcision was of special concern to them. They insisted that it was necessary for salvation. They did not omit faith in Christ but added works of the flesh. Paul called such men “deceitful workmen” (2 Cor. 11:13).3:2. Paul also called the Judaizers dogs, those men who do evil, those mutilators of the flesh. He considered their work dangerous and not of God. The saints were not to follow these people, but to beware of them, to watch out for them.It was common for some Jews to refer to Gentiles as dogs, which were considered unclean animals. Paul used the term to describe those Jews who mutilated the gospel by insisting on the need to mutilate the flesh in order to be rightly related to God. What they did was actually evil, even though they may have had good intentions.3:3. The Old Testament rite of physical circumcision was not only a sign of covenant relationship, but it was also intended to be related to spiritual circumcision of the heart (cf. Deut. 30:6). Writing to Gentiles, Paul made it clear that he and they were the true circumcision. This was because they had no confidence in the flesh and instead worshiped by the Spirit of God and gloried in Christ Jesus alone.Instead of boasting in human accomplishments, as the Judaizers and Jews did, a child of God should glory in Christ Jesus alone. The word glory (kauchōmenoi) used here means “boast” or “exult” (cf. 1:26; 2:16; 2 Cor. 10:17).
