early church people make a big thing about the judaising controversy, especially the penis part, and make these remarks about how “circumcision would get you nowhere, simply on a practical level!” but then like 500 years later along comes mr mohammed and says oh yeah u gotta clip off that hood and, sure, this is fine among the arabs and maybe the egyptians too, if they were still keeping that up from pharaoh times, but then Islam quickly spreads into Persia, a land of hooded heroes and there’s no problem there, then it keeps going into India, same deal, and all the way to Indonesia, and it doesn’t seem to be a deal, and it goes fine into the Maghreb and I presume Andalusia, and so on.
I think the foreskins of Europe owe more to Paul’s personal neuroses than any basic reticence on the part of the Romans.
