"Beware of the dogs, beware of the evil workers, beware of the false circumcision; for we are the true circumcision, who worship in the Spirit of God and glory in Christ Jesus and put no confidence in the flesh" (Philippians 3:2-3)In reading this, we must remember that Paul is speaking of those who were seeking to infiltrate the church, to pervert the Gospel of Christ, and to lead people astray from the purity of their life in Christ. There are many dogs and evil workers in the world today, but Paul is speaking specifically of those who oppose the church and our freedom in Christ.
The Greek word for "beware" means to see, look at, and perceive. It does not carry with it any connotation of fear or worry but merely means to be aware; to live life with our eyes wide open, We must no accept everything that comes claiming to be spiritual, godly, or Christian. We must look at it, examine it, to see if it has any worth, benefit, or support in the Gospel of Christ. The truth is that there are some people to whom we must not extend the right hand of fellowship. While we should love them, we must not embrace them. It says of Jesus, "But Jesus, on His part, was not entrusting Himself to them, for He knew all men, and because He did not need anyone to testify concerning man, for He Himself knew what was in man." (John 2:24-25) While Jesus loved the whole world, there were those whom he kept at arms-length, not trusting Himself to then, because He knew what was in their hearts. The same should be with us. There are some whom we must love, but whom we should not embrace and invite into close fellowship with ourselves. Paul writes to us, "And this I pray, that your love may abound still more and more in real knowledge and all discernment, so that you may approve the things that are excellent, in order to be sincere and blameless until the day of Christ." (Philippians 1:9-10) Love is not to be blind nor is it to be ignorant. Our love ought to be grounded in true knowledge and discernment. Loving everyone, but not always approving everyone.
In speaking of dogs, Paul is referring to those worthless people who are unfit for the Kingdom of God. In the scriptures, dogs are often depicted as those who devour what is unholy. "The one belonging to Ahab, who dies in the city, the dogs will eat, and the one who dies in the field the birds of heaven will eat." (1 Kings 21:24) They are those who revel in the dark. "they return at evening, they howl like a dog, and go around the city." (Psalms 59:6) And they are those who, after repenting, always return to their sin. "Like a dog that returns to its vomit is a fool who repeats his folly." (Proverbs 26:11)
In speaking of the "false circumcision," Pual does not actually use the word "circumcision" but "concision" which means to cut around and to mutilate. These are those who believe godliness can be obtained by mutilating the flesh. Paul reminds us that, "These are matters which have, to be sure, the appearance of wisdom in self-made religion and self-abasement and severe treatment of the body, but are of no value against fleshly indulgence." (Colossians 2:23) Concision of the flesh has no power to make us holy or righteous. Mere religion cannot make us Godly and it cannot deal with the true source of our sin which is inward and not outward. Circumcision of the flesh buys us nothing, What we need is a circumcision of the heart. Paul writes, "But he is a Jew who is one inwardly; and circumcision is that which is of the heart, by the Spirit, not by the letter; and his praise is not from men, but from God." (Romans 2:29) We must not yield to those who trust in the flesh or value religion over relationship with God.
