In submitting to the Law of Circumcision, Our Lord signifies that He is the fullness and the completion of the Old Covenant. St. Paul says, in the Epistle Lesson read on the Feast: For in [Jesus] the whole fullness of deity dwells bodily, and you have come to fullness of life in Him, Who is the head of all rule and authority. In Him also you were circumcised with a circumcision made without hands, by putting off the body of flesh in the circumcision of Christ (Col. 2:9-11).
