What is religious ritual except witchcraft? You are performing rites with no practical purpose, in an attempt to influence the future outcome of earthly events by either begging from a god (or angel, or demon, or saint, etc) – or else by symbolically replicating the outcome you want by dropping blood where you want rain or dressing up as the animal you want to kill – or else by sacrificing (“making sacred”, i.e. killing or destroying) an animal, child, or other valuable object.
So Abraham hears voices in his head. God tells him to sacrifice his son. He’s ready to do it, when he sees a ram caught in a bush, and the voices tell him to kill that instead. Lucky for the boy. Then God says he’ll make a deal with Abraham: worship Him only, and He’ll favor Abraham’s descendants as the Chosen People. (Seems like a good deal. It’s not being offered to anyone else. Except somehow every people on earth seems to think it’s more special than the others.)
And to prove they’re still committed to the deal, all Abraham’s descendants – forever – have to have their foreskins cut off. Which is a better blood-offering than actually killing yourself or one of your family. But this God is definitely one of the gods that likes to see a bit of blood.
And Abraham, being the first, circumcised himself. Nowadays we would just assume he was insane.
And then there are people like this man in British Columbia who figured things weren’t going right with the family because he hadn’t had his son circumcised. The doctors wouldn’t do it now that the boy was four. The man botched it. The son was hospitalized and is damaged for life. The father was convicted and jailed, and it was noted by the court that he had tried to circumcise himself a couple of years earlier.
So he’s just a lunatic, you say. (But not that different from Abraham.) You can’t apply that criticism to trained religious practitioners, you say.
Strictly speaking, the father is meant to do the circumcision if he’s able, but there’s always someone willing to be paid to do it for you. So there’s the Jewish practitioner, the mohel. Orthodox Judaism prescribes circumcision as a religious ritual, to be performed according to strict Talmudic laws. According to those laws, the mohel must suck the infant’s bleeding penis with his mouth. (How Abraham achieved this isn’t explained.) So when a mohel has a sexually transmitted disease like herpes, might there be a risk? Here’s a report of a two-week-old boy who died in New York, thanks to his mohel.
It’s not just uneducated people whose magical thinking leads to witchcraft and deaths. A religious education can be just as dangerous.
