"But if any man say unto you, This is offered in sacrifice unto idols, eat not for his sake that shewed it, and for conscience sake: for the earth is the Lord's, and the fulness thereof" (1 Corinthians 10:28).
Owners of Butterball want to "Halal" turkeys ?...Paul's clear instructions here are to not eat them for THEIR sake.
1 Corinthians 10:29-33 (KJV)
29 Conscience , I say , not thine own, but of the other: for why is my liberty judged of another man's conscience?
30 For if I by grace be a partaker , why am I evil spoken of for that for which I give thanks ?
31 Whether therefore ye eat , or drink , or whatsoever ye do , do all to the glory of God.
32 Give none offence, neither to the Jews, nor to the Gentiles, nor to the church of God:
33 Even as I please all men in all things, not seeking mine own profit , but the profit of many, that they may be saved
I notice that you started after the situation was established. Let's look at verse 27 real quick:
27 If any of them that believe not bid you to a feast, and ye be disposed to go ; whatsoever is set before you, eat , asking no question for conscience sake.
So, what Paul has stated is that if you are invited to eat at a feast given by a non-believer, eat whatever is set before you without questioning the host. But if the host makes it a point to inform everyone that the meat was sacrificed to an idol, do not eat, because he has made a point out of making it public. Why? Because your testimony is at stake and might wound the conscience of those who hear about it.
Butterball did not come to your house and tell you of their halal preperations, you went asking about it. (See verse 27, where he says "asking no questions for conscience sake"?)
Paul repeatedly talked about food sacrificed to idols, and his conclusion was there was no problem with it. This portion of scripture deals with public behavior, not eating food sacrificed to idols.
