If you notice a lot of old testament scripture has to do with leading a healthier life, not just spiritual teachings.
You got it.....and in this case, as much for the ladies health as well.
Bingo. Makes my point.
However, its a common idea with Christians today (probably from the popular book in the '70s None of These Diseases) that the food regulations were all about physical health...and that puts the cart before the horse. Of course it was heathier not to eat nasty parisite-ridden wild bore in the ancient near-East.
However, the FIRST reason not to do so was a spiritual one--as pigs were an essential part of the neighboring pagan religions. If you grow up never eating pork--you won't share a ham sandwich with your evil pagan neighbors--so you won't get to be good friends...your kids won't marry them....and your posterity won't be swallowed up in a foreign pagan people. This is one reason the Jews still exist today (when did you last meet a Celt, an Amorite or a Babylonian?) as a seperate people--they don't eat like the rest of the world--hence they survive as a people. Has Kosher law ALSO aided in health? Why yes, of course--as God is a good God.
Still the first reason for it--in Old Covenant times was to keep the chosen people of God pure and separated from other evil pagan nations.
Of course we are no longer in Old Covenant times--and Christians have a Holy Spirit in them to help keep them pure--even when they share the ham sandwiches (or uncircumcision)of pagan peoples.
Though the spiritual situation has changed, do the side health benefits still remain? Of course.
I'd like to see the stats of male urinary problems and feminine cevical cancer rates in other (non-circumcising) Western countries compared to the USA. I bet we (and Israel) are amoung the best in the world for those problems.
