Majority of Christians eat pork, though it's prohibited by the bible, yet there's a pro-vegetarian trend going on, even one called Christian vegetarianism. But eating meat is not prohibited in the bible.
Why are they concerned by what God has not commanded and unconcerned by what He has commanded?
Of course most Christians would say the old testament is not binding on them, but that doesn't have anything to back it up.
Mark 7:17-23
17 After he had left the crowd and entered the house, his disciples asked him about this parable. 18 “Are you so dull?” he asked. “Don’t you see that nothing that enters a person from the outside can defile them? 19 For it doesn’t go into their heart but into their stomach, and then out of the body.” (In saying this, Jesus declared all foods clean.)
20 He went on: “What comes out of a person is what defiles them. 21 For it is from within, out of a person’s heart, that evil thoughts come—sexual immorality, theft, murder, 22 adultery, greed, malice, deceit, lewdness, envy, slander, arrogance and folly. 23 All these evils come from inside and defile a person.”
Also, I found it interesting the other day to see that God made a covenant with Noah where he said it was ok to eat anything on earth. Genesis 9:3 Everything that lives and moves about will be food for you. Just as I gave you the green plants, I now give you everything.
So, yes, "Christians", you can eat pork.
