“For we are the circumcision; those who worship in the Spirit of God and who boast in Christ Jesus and who do not trust in the flesh.”
Indeed, in Christ’s economy, circumcision is no longer a matter of the flesh, but is a matter of the heart. To take the notion one step further, we should argue that circumcision of the flesh was always meant to be a physical symbol of an inward reality — an inward circumcision. And, as noted above, as the physical symbol changed (circumcision to baptism), the physical cutting is no longer deemed necessary while the inward reality (a circumcised heart) remains the same. Thus not only is Paul of the circumcision (physical and spiritual) the uncircumcised (physically) gentiles who were a part of the church in Philippi are circumcised in the eyes of God (spiritually). If the cutting is done out of ritual or as a sign of works it is an abomination…a mutilation of the flesh; the cutting that takes place in the heart is worked by God and by God alone upon us and is designed to prepare us for glory (as well as to equip us to live out our life in the here and now.
And ultimately, then, what is the visible mark of this inward circumcision? In addition to baptism, it is a life that is lived glorying in Christ and not trusting in the works of the flesh. It is a life marked by worship in the Holy Spirit and not by worshipping in the strength or pattern of the flesh. It is a life that is oriented around serving God (the word in this passage which we translate as “worship,” literally means “to serve in a liturgical or religious manner”).
The question we must set before us is whether or not this is how we live. Is this what we strive for? Do we still take pride in our flesh or is the only thing in which we glory the work of Christ in and over this weak flesh of ours? The former relies on an outward circumcision; the latter relies on an inward. And Paul will shortly remind us that the outward circumcision avails us nothing if we seek to stand upon it. The bottom line is that it is all about Christ, from beginning to end, it is all about Jesus.
My hope is built on nothing less
than Jesus’ blood and righteousness;
I dare not trust the sweetest frame,
But wholly lean on Jesus’ name.
