It seems the church of the Philippians, though a faithful and flourishing church, was disturbed by the judaizing teachers, who endeavoured to keep up the law of Moses, and mix the observances of it with the doctrine of Christ and his institutions. He begins the chapter with warnings against these seducers. MHBCC 1107.2
I. He exhorts them to rejoice in the Lord (Philippians 3:1), to rest satisfied in the interest they had in him and the benefit they hoped for by him. It is the character and temper of sincere Christians to rejoice in Christ Jesus. The more we take of the comfort of our religion the more closely we shall cleave to it: the more we rejoice in Christ the more willing we shall be to do and suffer for him, and the less danger we shalt be in of being drawn away from him. The joy of the Lord is our strength, Nehemiah 8:10. MHBCC 1107.3
II. He cautions them to take heed of those false teachers: To write the same thing to you to me indeed is not grievous, but for you it is safe; that is, the same things which I have already preached to you; as if he had said, “What has been presented to your ears shall be presented to your eyes: what I have spoken formerly shall now be written; to show that I am still of the same mind.” To me indeed is not grievous. Observe, 1. Ministers must not think any thing grievous to themselves which they have reason to believe is safe and edifying to the people. 2. It is good for us often to hear the same truths, to revive the remembrance and strengthen the impression of things of importance. It is a wanton curiosity to desire always to hear some new thing. It is a needful caution he here gives: Beware of dogs, Philippians 3:2. The prophet calls the false prophets dumb dogs (Isaiah 56:10), to which the apostle here seems to refer. Dogs, for their malice against the faithful professors of the gospel of Christ, barking at them and biting them. They cried up good works in opposition to the faith of Christ; but Paul calls them evil workers: they boasted themselves to be of the circumcision; but he calls them the concision: they rent and tore the church of Christ, and cut it to pieces; or contended for an abolished rite, a mere insignificant cutting of the flesh. MHBCC 1107.4
III. He describes true Christians, who are indeed the circumcision, the spiritual circumcision, the peculiar of people of God, who are in covenant with him, as the Old-Testament Israelites were: We are the circumcision, who worship God in the spirit, and rejoice in Christ Jesus, and have no confidence in the flesh. Here are three characters:—1. They worshipped in the spirit, in opposition to the carnal ordinances of the Old-Testament, which consist in meats, and drinks, and divers washings, etc. Christianity takes us off from these things, and teaches us to be inward with God in all the duties of religious worship. We must worship God in spirit, John 4:24. The work of religion is to no purpose any further than the heart is employed in it. Whatsoever we do, we must do it heartily as unto the Lord; and we must worship God in the strength and grace of the Divine Spirit, which is so peculiar to the gospel state, which is the ministration of the spirit, 2 Corinthians 3:8. 2. They rejoice in Christ Jesus, and not in the peculiar privileges of the Jewish church, or what answers to them in the Christian church—mere outward enjoyments and performances. They rejoice in their relation to Christ and interest in him. God made it the duty of the Israelites to rejoice before him in the courts of his house; but now that the substance has come the shadows are done away, and we are to rejoice in Christ Jesus only. 3. They have no confidence in the flesh, in those carnal ordinances and outward performances. We must be taken off from trusting in our own bottom, that we may build only on Jesus Christ, the everlasting foundation. Our confidence, as well as our joy, is proper to him. MHBCC 1107.5
