Completely irrelevant on a couple of points, but particularly with regards the dietary recommendations of the OT. God promised Israel they would be protected from the diseases of Egypt, from which they had just been set free after 400 years of eating crocodiles, snakes, lizards, and birds of prey, among other things. As a result they were feeble and prone to disease. God loved them, and wanted the best for them. So He had to go over a few things they'd forgotten. The very first thing was to distinguish between what was good and what was bad for health. Nothing to do with ceremony or laying down a type or pointer to Christ. It was solely to make them a strong people, and yes, to distinguish them as His own and sanctified in the midst of nations that ate anything, including each other and their own children.
You will not find one reference in scripture to unclean food. Unclean flesh, yes. But unclean flesh was never categorized as food. Never. That was the difference between unclean and clean. One was food, the other wasn't.
Wrong, Israel left Egypt in perfect health, without a feeble person among them.
Laws of clean and unclean were completely ceremonial, including being unclean until evening after touching a dead animal, including a woman being unclean for 7 days after her period,
I proved unequivocally the truth already in an earlier post, that proved they were ceremonial because both before and after the law o Moses, all animals could then, and can now, be eaten.
Here’s the irrefutable proof I posted earlier.
God told Noah IF IT MOVES,YOU CAN EAT IT:
Clean and unclean animals was 100% ceremonial law given to Israel, as proven by the fact that before, and after, the law of Moses was given, all animals are okay to eat.
God told Noah post flood, and before the law, that if it moves, he can eat it:
Gen 9:3 Every moving thing that lives shall be food for you. And as I gave you the green plants,
I give you everything.
Noah could eat all. animals - every living thin that moves includes them all.
And in the new Covenant, Peter learned in Acts 10 that the gentiles, who were considered unclean and completely outside of Gods covenant because they ate unclean meat, could now enter into the new covenant,
because God told Peter three times that laws of clean and unclean animals were ended, and that he could kill and eat them.
Then in the passage that Paul was talking about eating meat in, he stated that there is nothing unclean of itself:
Rom 14:2 For one believeth that he may eat all things: another, who is weak, eateth herbs.
Rom 14:14 I know, and am persuaded by the Lord Jesus, that there is nothing unclean of itself: but to him that esteemeth any thing to be unclean, to him it is unclean.
Rom 14:15 But if thy brother be grieved with thy meat, now walkest thou not charitably. Destroy not him with thy meat, for whom Christ died.
Finally, Jesus tells the Jews who considered that eating unclean animals defiled the body, that there is nothing you can eat that defiles a man, for its what comes out of a man from his heart, that defiles him.
It’s pretty clear that unclean animal law was absolutely ceremonial in nature, and peculiar to the law of Moses.
Before and after the law, animals were not unclean.
