The unregenerate refuse to understand that food laws, 1) were peculiar to Israel under the old covenant and not reiterated to the church under the new covenant, in fact, under the New C8venant, ALL FOODS are declared legal.Disagree. God's morality once said it was immoral to eat pork or clam chowder. That has changed.
2) Food laws given to Israel are not moral laws, they are food laws peculiar to Israel. We never see God punishing gentile nations for not observing food laws, do we, rossum? No, we don't. We do see them being punished for breaking the moral laws.
Regarding the moral laws, all men, believer and unbeliever alike are obligated to adhere to them. Moral laws are recorded in the 10 commandments and laws outlining unacceptable sexual behavior.
