I’m assuming you are talking about this verse:
(Acts 15:19-21)
But it needs to be taken in context with otherverses int he new testament:
1 Corinthians chapter 8
Also 1 Corinthians 6:12 and 1 corinthians 10:23
The point of the verse in Acts is to give rules to the gentiles who are coming in to the church through Christ so that the mingling of Jew and Gentile goes smoother. Basically, all the laws of OT were fulfilled. This is why we’re allowed to eat pork and wear mixed fabrics now. This is one of those laws. The Jews still observed them, the gentiles did not. When gentiles came in through Christ, there was a huge problem with them not following traditional law. Acts 15 is an example of how they tried to work it out, and St. Paul later clarifies it in Corinthians.
1 Cor. 8
This has nothing to do with the eating of blood or the law on clean and unclean meats. Notice verse 1: “Now, as touching THINGS OFFERED UNTO IDOLS….” And again, verse 4:”As concerning therefore the eating of those things that are OFFERED IN SACRIFCE UNTO IDOLS….” The subject matter clearly is meats offered to idols.
I Cor. 6:12 and 1 Cor. 10:23:
“All things are lawful for me” – did Paul mean robbery, or murder? Of course not. Obviously, all LAWFUL things, not unlawful things, are lawful for Paul. If eating unclean meats is unlawful, then that is not part of things lawful for Paul.
NOT ONE WORD is said about blood or unclean foods in 1 Cor. 10:23-33. The entire subject is, again, meats “offered in sacrifice to idols” (I Cor. 10:19).
It was the practice of the pagan Romans and Greeks to slaughter animals to various pagan gods. The animals could then be sold in the meat markets. Because many Christians believed the meat was somehow contaminated if the animal were killed in sacrificial rites, they avoided eating it. Paul explained that a non-existent “god” or pagan idol had no power to contaminate edible meat. If one person believed the meat had been offered in sacrifice to an idol, and was therefore contaminated, the person who knew that the idol had no power to contaminate the meat – that it was perfectly edible – should not exercise his “lawful” privilege to eat if it would offend the conscience of another. Here, the entire matter is to avoid defiling the conscience of a brother.
Paul concluded the passage by saying, “But if any man say unto you, This is offered in sacrifice to idols, eat not for his sake that showed it, and for conscience sake… Conscience, I say, not thine own, but of the other: for why is my liberty [to eat edible meat, even though sacrificed to a dead, non-existent “god”] judged of another man’s conscience?..” (v. 28-33).
