"Are you so dull?" he asked. "Don't you see that nothing that enters a man from the outside can make him 'unclean'? For it doesn't go into his heart but into his stomach, and then out of his body." (In saying this, Jesus declared all foods "clean.") (Mark 7:18,19)That is significant, because people who magnify the Torah (Genesis through Deuteronomy) and fatally de-emphasize or avoid Jesus' teachings, aren't aware of such an important change.
For if anyone with a weak conscience sees you who have this knowledge eating in an idol's temple, won't he be emboldened to eat what has been sacrificed to idols? So this weak brother, for whom Christ died, is destroyed by your knowledge. When you sin against your brothers in this way and wound their weak conscience, you sin against Christ. Therefore, if what I eat causes my brother to fall into sin, I will never eat meat again, so that I will not cause him to fall. (1 Cor 8:10-13)
Another passage from Paul adds to all of this:
They [false teachers] forbid people to marry and order them to abstain from certain foods, which God created to be received with thanksgiving by those who believe and who know the truth. For everything God created is good, and nothing is to be rejected if it is received with thanksgiving, because it is consecrated by the word of God and prayer. (1 Tim 4:3-5)
Instead we should write to them, telling them to abstain from food polluted by idols, from sexual immorality, from the meat of strangled animals and from blood. (Acts 15:20)
It seemed good to the Holy Spirit and to us not to burden you with anything beyond the following requirements: You are to abstain from food sacrificed to idols, from blood, from the meat of strangled animals and from sexual immorality. You will do well to avoid these things. Farewell. (Acts 15:28,29)In both passages, their dietary restrictions are detailed. Again, Gentile Christians were to abstain from food sacrificed to idols. The blood they were to abstain from was the drinking or eating of it, which is not related to a blood transfusion, as misunderstood by Jehovah's Witnesses. How could it be a blood transfusion since such never existed in that day? So you can now eat pork and rabbit, if you want. Neither will make you unclean, as in Moses' day, but you'd never know that by focusing on the Torah. Now that you know what the Bible says about food, what are you going to do about it?
