1 Finally, my brethren, rejoice in the Lord. For me to write the same things to you is not tedious, but for you it is safe. 2 Beware of dogs, beware of evil workers, beware of the mutilation! (Philippians 3:1–2, NKJV)
Identifying enemies of the truth and warning against those who destroy souls with their false doctrines and sinful conduct is not pleasant. Undoubtedly, that is why many refuse to do it. They prefer to let others do the hard work of exposing “the enemies of the cross of Christ” (Phil. 3:18; Eph. 5:11). Yet, Paul said doing so was necessary for the spiritual safety of the Philippian Christians. He did not see this work as bothersome, and he would not neglect it (v. 1). He gives three warnings concerning those “whose end is destruction, whose god is their belly, and whose glory is their shame—who set their minds on earthly things” (Phil. 3:20). 1) Beware of dogs. Isaiah described the irresponsible watchmen (leaders) of Israel as “dumb” (silent), lazy, and “greedy” (Isa. 56:10-11). There are still people who scavenge for the souls of the innocent, like pack dogs. Jesus warned of these “dogs” (Matt. 7:6). 2) Beware of evil workers. You will know the false prophets who speak in the name of the Lord by their fruit when they stray from the commands of God (Matt. 7:15-21; Psa. 119:115). 3) Beware of the mutilation. Those who bound physical circumcision on Gentiles for salvation were mutilators who put confidence in the flesh instead of the Spirit (Phil. 3:3; Gal. 6:12-13; Col. 2:11-12). That is what error always does and why it must be resisted (Jude 3).
