Philippians 3:3

We are the circumcision - We, who have embraced the faith of Christ crucified, are now entered into the new covenant, and according to that new covenant, worship God in the Spirit, exulting, καυχωμενοι, making our boast of Christ Jesus, as our only Savior, having no confidence in the flesh - in any outward rite or ceremony prescribed by the Jewish institutions.

For we are the circumcision - We who are Christians. We have and hold the true doctrine of circumcision. We have that which was intended to be secured by this rite - for we are led to renounce the flesh, and to worship God in the spirit. The apostle in this verse teaches that the ordinance of circumcision was not designed to be a mere outward ceremony, but was intended to be emblematic of the renunciation of the flesh with its corrupt propensities, and to lead to the pure and spiritual worship of God. In this, he has undoubtedly stated its true design. They who now urged it as necessary to salvation, and who made salvation depend on its mere outward observance, had lost sight of this object of the rite. But this, the real design of circumcision, was attained by those who had been led to renounce the flesh, and who had devoted themselves to the worship of God; see the notes at Romans 2:28-29.

Which worship God in the spirit - See the notes at John 4:24; compare Genesis 17:10-14.

And rejoice in Christ Jesus - See Philippians 3:1. That is, we have, through him, renounced the flesh; we have become the true worshippers of God, and have thus attained what was originally contemplated by circumcision, and by all the other rites of religion.

And have no confidence in the flesh - In our own corrupt nature; or in any ordinances that relate merely to the flesh. We do not depend on circumcision for salvation, or on any external rites and forms whatever - on any advantage of rank, or blood. The word "flesh" here seems to refer to every advantage which any may have of birth; to any external conformity to the law, and to everything which unaided human nature can do to effect salvation. Or none of these things can we put reliance for salvation; none of them will constitute a ground of hope.

3:3 For we - Christians. Are the only true circumcision - The people now in covenant with God. Who worship God in spirit - Not barely in the letter, but with the spiritual worship ofinward holiness. And glory in Christ Jesus - As the only cause of all our blessings. And have no confidence in the flesh - In any outward advantage or prerogative.
