Charles Spurgeon Commentary Colossians 2:11

"in whom ye were also circumcised with a circumcision not made with hands, in the putting off of the body of the flesh, in the circumcision of Christ;" — Colossians 2:11 (ASV)

Where there is neither Greek nor Jew, circumcision nor uncircumcision, Barbarian, Scythian, bond nor free: but Christ is all, and in all.

In the new life there is no distinction of race and nationality. We are born into one family and become members of Christ's body. And this unity is the one thing we must maintain: separation from the rest of the world, no divisions in the church, no disunity, and nothing that would cause it, for we are one in Christ, and Christ is all. Now, as we have to put off these things, that is the negative side: it is the law's side, for the law says, Thou shalt not – Thou shalt not. But now look at the positive side.

In whom also you are circumcised with the circumcision made without hands, in putting off the body of the sins of the flesh by the circumcision of Christ:

Anything good that there was in Judaism, has been secured for you in Christ. Whatever there was of blessing and privilege in the covenant mark in the flesh of those whom God made to be His people in former times, has been handed on to you by the death of Christ.
