60 This difference between the Christian and the worldly life also arises from the fact that we are conscious of having been truly justified. Justification is produced in us by our sharing in the paschal mystery, particularly in Baptism, which is truly a rebirth, as St. Paul teaches: "All who are baptized in Christ Jesus are baptized in his death. For we are buried together with him by baptism into death: that as Christ is risen from the dead by the glory of the Father, so we also may walk in newness of life." (39)
