btw, the Bible has something interesting to say about Circumcision from Galations 6. Paul literally wrote this in huge letters it was so important:

11 See what large letters I use as I write to you with my own hand!

12 Those who want to impress people by means of the flesh are trying to compel you to be circumcised. The only reason they do this is to avoid being persecuted for the cross of Christ. 13 Not even those who are circumcised keep the law, yet they want you to be circumcised that they may boast about your circumcision in the flesh.
