Paul did NOT go against God's health law written in Deuteronomy 14.
Paul did not say eating from the unhealthy list of meats was now miraculously clean. He taught that we are not to judge... based on what meat one eats, but he never said that somehow now unhealthy meats are now clean for our body. That's the difference. The proof of that is how many are sick from living on unhealthy foods.
So if you like dem' arteries good and clogged up, keep eating scavenger meats which God created to cleanse the earth, and that process poisons which stay in the meat and fat. With some, it takes longer for their arteries to get clogged, with others not as long, leading to heart bypass surgery.
In 1 Corinthians 10:25, Paul said whatever is sold in the shambles (market), that eat. The idea is to eat to live.
Will our flesh be healthy by eating pork and shellfish (shrimp, crab, lobster, oysters, squid, gator, catfish, ie. scavengers)? NO! And that's what God's healthy meat list He gave is about.
If you want your flesh body to be healthier by eating clean meats, that means meats that God "created to be received". Even as Christians we should never get away from that fact.
Furthermore, the Colossians 2:14 Scripture about Jesus having blotted out the handwriting of ordinances of God's law on His cross, those 'ordinances' DO NOT MEAN ALL OF GOD'S LAWS. Those ordinances specifically apply to the blood and ritualistic ordinances. If it meant all of God's law was nailed to Christ's cross, then it would now be legal to steal, lie, murder, rape, etc., you see what I mean? So do not listen to the 'lawless', because that is how Satan and his children operate.
(And NO, I am not Jewish).
