How then does circumcision relate to baptism? Just as circumcision was a sign and seal of the Christ who was to come, so baptism is a sign and seal of the Christ who came. Circumcision looked forward in history, and Christian baptism looks back in history, but they both testify to the same Christ, the same Lord of the Covenant. Neither circumcision nor baptism primarily testifies concerning the inward state of the individual who bears the sign and seal; they testify of Christ.
