No, I do not agree with the assertion that modern farming and advances in biology and nutritional information have made it okay to eat the flesh of swine. But again, that’s just me and my understanding of what I have read. I don’t think that YHVH was mistaken when he wrote any of the Bible. If it was a simple matter of micro-biology (he is the author of all science) he could have simply given good cooking directions.
I've wondered if perhaps age ailments are caused by eating unclean foods...arthritis, alzheimers, vascular problems, etc. Could it be a build-up of the toxins from the food eaten over the years?
If the very detailed list of unclean foods wasn't good for humans long, long ago...I would assume it still isn't. But, maybe not. Those willing to take the risk should shoot and serve buzzard next chance they get. Yummm, I bet they're great served with carrots and parsley and wrapped in bacon. Come and get it....time for Mom's famous Buzzard explosion!
That's a strawman. - The question is whether a man can be mistaken in his interpretation of what YHWH wrote.
