Um, did I miss something?
1 Corinthians 10:28 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:
He said there NOT to eat both as an example and testimony to the person who served meat offered to idols and for his own conscience sake.
Take that in context with 1 Corinthians 8.
“Now about food sacrificed to idols: We know that “We all possess knowledge.” But knowledge puffs up while love builds up. 2 Those who think they know something do not yet know as they ought to know. 3 But whoever loves God is known by God.
4 So then, about eating food sacrificed to idols: We know that “An idol is nothing at all in the world” and that “There is no God but one.” 5 For even if there are so-called gods, whether in heaven or on earth (as indeed there are many “gods” and many “lords”), 6 yet for us there is but one God, the Father, from whom all things came and for whom we live; and there is but one Lord, Jesus Christ, through whom all things came and through whom we live.
7 But not everyone possesses this knowledge. Some people are still so accustomed to idols that when they eat sacrificial food they think of it as having been sacrificed to a god, and since their conscience is weak, it is defiled. 8 But food does not bring us near to God; we are no worse if we do not eat, and no better if we do.
9 Be careful, however, that the exercise of your rights does not become a stumbling block to the weak. 10 For if someone with a weak conscience sees you, with all your knowledge, eating in an idol’s temple, won’t that person be emboldened to eat what is sacrificed to idols? 11 So this weak brother or sister, for whom Christ died, is destroyed by your knowledge. 12 When you sin against them in this way and wound their weak conscience, you sin against Christ. 13 Therefore, if what I eat causes my brother or sister to fall into sin, I will never eat meat again, so that I will not cause them to fall.”
In 1 Corinthians 10:29-30, Paul says, “I am referring to the other person’s conscience, not yours. For why is my freedom being judged by another’s conscience? 30 If I take part in the meal with thankfulness, why am I denounced because of something I thank God for?”
The issue is not whether a pagan idol can corrupt meat-—it can’t. Just as it can’t corrupt a Christmas tree. The issue is not causing a brother or sister to sin.
In other words, the meat is fine to eat unless you are of a mind that it isn’t. One shouldn’t violate one’s conscience to do something he believes is wrong, nor should he encourage a fellow Christian to do so.
