There's a lot of people who think that parts of the Bible don't apply to them. I always suggest they get a Bible they don't mind defacing, and every time they find a part they think doesn't apply they should rip that page out. Then at the end of a year, they should look back at just how much of God's word they have dismissed as irrelevant to them.
Do I eat pork? Thanks To Jesus yes I do. But the point of the pork prohibition is to abstain from unclean things. And it applies today because we likewise should abstain from the unclean things of today. Pork is no longer on that list but things like lust and idolatry still are. So while God in that dispensation told those of old to not eat unclean pork, in this dispensation it still applies that we are to likewise abstain from the unclean things of our day.
I'm afraid pork still is... on that unclean list. Christ didn't change His creation upon His cross.
Lobster, crab, shrimp, clams, catfish, scallops, (all which I love except catfish), are all still unclean too, higher in cholesterol than even beef. God created the unclean things to cleanse the earth, not be food for us. He created animals that mostly eat grains for our food.
And because of man's ignorance on these things, they tried to feed cows scrap meat mixed in their feed and that's what caused Mad Cow disease. Cows were designed by God to eat grains, to graze, not eat meat.
I was raised on pork (I'm from the South). It clogged my parents arteries, and it clogged mine, but I lived, they didn't.
When Paul said to eat whatever is put before us when we are invited to the house of the unbeliever, it was for The Gospel's sake. He didn't teach that God changed His unclean list. When Paul said to eat whatever is sold in the market (shambles), that idea is about not starving, so you eat what's available. It's not a teaching to intentionally get away from eating healthy per God's clean list.
