Biblically, circumcision was a form of sacrifice (shedding of blood to establish a covenant between God and man).
It was a tiny sliver of skin which was shaved off the tip of the foreskin. Today, medical based circumcision removes the skin cover the entire gland of the penis – equivalent to 15 square inches.
When Christ died, the veil was torn, as was his body as the final sacrifice needed to atone for our sin. We no longer need to adhere to sacrificial practices of the old covenant.
We are created in the image of Christ. Christ, Himself, had a foreskin.

“Watch out for those wicked men – dangerous dogs, I call them – who say you must be circumcised. Beware of the evil doers. Beware of the mutilation. For it isn’t the cutting of our bodies that makes us children of God; it is worshiping him with our spirits.” – Phil 3:2-3

“As God has called each man, in this manner let him walk. And thus I command in all the churches. Was any man called in the circumcision [Old Covenant]? Let him not try to become uncircumcised.

Let each man remain in that condition in which he was called.” – 1 Cor. 7:17
