In response to the original post: Jack, I don't think there is a "Christian version" of circumcision in any denomination, but I may be wrong. Many Christians circumcise their male children, but not for religious reasons. I'm sure there must be a Christian religious sect somewhere that circumcises for religious purposes, but I don't know of any myself. Wikipedia seems to indicate that some Christian cultures in history have practiced circumcision for religious purposes.

Muslim circumcision, called Khitan, includes female genital mutilation in some cultures.

I'm not ready to give an outright condemnation of circumcision and other genital mutilation. I just don't know.
