Many don't understand what circumcision is. It's a circumcision of the heart, a doing away of sins.
Colossians 2:11-12--In whom also ye are circumcised with the circumcision made without hands, in putting off the body of sins of the flesh, by the circumcision of Christ: 12--Buried with Him in baptism, wherein also you are risen with Him through the faith of the OPERATION OF GOD, who hath raised Him from the dead
Romans 2:29--But he is a Jew, which is one inwardly; and circumcision IS THAT OF THE HEART, in the spirit, and not in the letter; whose praise is not of men, but of God.
Philippians 3:3--For we are the circumcision, which worship God in the spirit, and rejoice in Jesus Christ, and have no confidence in the flesh.
