Circumcision, Baptism, the Cross, and Defeated Powers
Paul describes union with Christ through a cluster of covenant and exodus-like images. Believers receive a circumcision “made without hands,” are buried with Christ in baptism, and are raised with him through faith in God’s power. Those once dead in sins are made alive and forgiven. The record that stood against them is canceled and nailed to the cross, while principalities and powers are stripped and publicly triumphed over.
Where this fits in the story: the prophets had already pressed circumcision inward toward the heart, and the New Testament develops that trajectory around the work of Christ and the Spirit. Baptism is joined to death-and-resurrection participation, while the cross becomes both the place of forgiveness and the decisive defeat of hostile powers.
