"Do you not know that all of us who have been baptized into Christ Jesus were baptized into his death? Therefore we have been buried with him by baptism into death, so that, just as Christ was raised from the dead by the glory of the Father, so we too might walk in newness of life. For if we have been united with him in a death like his, we will certainly be united with him in a resurrection like his." (Romans 6:3–5)

"I have been crucified with Christ, it is no longer I who live, but it is Christ who lives in me. And the life I now live in the flesh I live by faith in the Son of God, who loved me and gave himself for me." (Galatians 2:19b–20)

In many Western Christian churches, particularly Anglicanism, the Pauline dying and rising theology dominates in the baptismal liturgy and therefore in our baptismal theology. The baptismal liturgy of the Canadian Book of Alternative Services circles around the image and reality of dying and rising in several different ways. One example is the concluding prayer of the litany sung on the way to the font: Grant, O Lord, that all who are baptized into the death of Jesus Christ your Son may live in the power of his resurrection and look for him to come again in glory; who lives and reigns now and for ever.

Perhaps the Pauline imagery of dying to self and living in Christ is most apparent in the outward expressions of having been “Christed” in baptism—which is primarily at the chrismation, accompanied by the words “I sign you with the cross, and mark you as Christ’s own for ever,” as well as other non-optional ritual texts.
