The modern form of circumcision is vastly worse than the Biblical form of circumcision. In the past, only the very tip of the foreskin was removed, and it was such a minor surgery that a man could be circumcised in the morning, and be able to fight a battle later that day. Today's circumcision removes the entire foreskin, requiring stiches, and weeks of recovery.

And, Biblically, Paul explicitly states in Galatians that circumcision is no longer required for Christians. To even entertain the idea that circumcision is necessary, invites Christians to become slaves to all of Hebraic law again, which does not save us, and only serves to condemn us, as no one can be perfectly saved by the law (of man). Jesus nullified all of the Hebraic laws. In Galatians, Paul was specifically rebuking the Galatian churches that had begun to judaize (the first Christian heresy), where jews of that day were trying to force the new gentile Christians into now defunct Hebraic laws.

Galatians 3:1-7

O foolish Galatians! Who has bewitched you? It was before your eyes that Jesus Christ was publicly portrayed as crucified. 2 Let me ask you only this: Did you receive the Spirit by works of the law or by hearing with faith? 3 Are you so foolish? Having begun by the Spirit, are you now being perfected by the flesh? 4 Did you suffer so many things in vain—if indeed it was in vain? 5 Does he who supplies the Spirit to you and works miracles among you do so by works of the law, or by hearing with faith— 6 just as Abraham “believed God, and it was counted to him as righteousness”? 7 Know then that it is those of faith who are the sons of Abraham.

Galatians 5:1-6

For freedom Christ has set us free; stand firm therefore, and do not submit again to a yoke of slavery. 2 Look: I, Paul, say to you that if you accept circumcision, Christ will be of no advantage to you. 3 I testify again to every man who accepts circumcision that he is obligated to keep the whole law. 4 You are severed from Christ, you who would be justified by the law; you have fallen away from grace. 5 For through the Spirit, by faith, we ourselves eagerly wait for the hope of righteousness. 6 For in Christ Jesus neither circumcision nor uncircumcision counts for anything, but only faith working through love.

Galatians 6:11-16

See with what large letters I am writing to you with my own hand. 12 It is those who want to make a good showing in the flesh who would force you to be circumcised, and only in order that they may not be persecuted for the cross of Christ. 13 For even those who are circumcised do not themselves keep the law, but they desire to have you circumcised that they may boast in your flesh. 14 But far be it from me to boast except in the cross of our Lord Jesus Christ, by which the world has been crucified to me, and I to the world. 15 For neither circumcision counts for anything, nor uncircumcision, but a new creation. 16 And as for all who walk by this rule, peace and mercy be upon them, and upon the Israel of God.
