In the book of Genesis we are told that circumcision was commanded by God as a sign of His covenant; interestingly, the failure to do this is described as the fault of the [8 days old] child. Genesis 17:14 states that “Any uncircumcised male who is not circumcised in the flesh of his foreskin shall be cut off from his people; he has broken my covenant.” We are, it seems, back to the God as moral monster scenario – the failure of the an infant to be circumcised is a conscious defect on the part of the infant!
As it happens, along with most Jews, I do not believe God is a moral monster – sharing, as I do as a Christian, much of the same scripture (and a far more ugly legacy of evil actions perpetuated in the name of my faith). Neither however do I believe that God takes any pleasure or delight in the ritual mutilation of infant children, whether it is done in His name or not. It was wrong when Abraham (allegedly) did it; it is also wrong now; that it is done in the name of religion or that it is conducted with pious sincerity and good intent by otherwise good people does nothing to mitigate this. Should the brit milah persist into the 21st century, let it be the voluntary act of a child or man of appropriate age making a rational and religiously meaningful act as sign of his own devotion to his faith and his decision to voluntarily stand subject to a great tradition.
