'But if any man say to you, "This has been offered in sacrifice in a temple (hierothyton)," do not eat, for his sake who revealed it, and for conscience sake. Conscience, I say, not your own, but the other's.'
Thus if someone deliberately draws their attention to the fact that the meat has been offered to idols in a temple, then they must immediately think of the effect that their eating will have on others, and abstain from eating. This not for the sake of their own conscience, but for the sake of the conscience of the other who clearly sees it as significant. It will then be a testimony that they have nothing to do with idols and idolatry, and will not sow error or doubts in the observer's mind. It should be noted that the very fact that the question is being asked should put them on the alert that their response does matter and will be judged.
