"Now about food sacrificed to idols: We know that we all possess knowledge. Knowledge puffs up, but love builds up. The man who thinks he knows something does not yet know as he ought to know. But the man who loves God is known by God. 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. For even if there are so-called gods, whether in heaven or on earth (as indeed there are many “gods” and many “lords”), 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. But not everyone knows this. Some people are still so accustomed to idols that when they eat such food they think of it as having been sacrificed to an idol, and since their conscience is weak, it is defiled. But food does not bring us near to God; we are no worse if we do not eat, and no better if we do. Be careful, however, that the exercise of your freedom does not become a stumbling block to the weak. 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,"
I do not read Paul saying it is okay to eat meat offered to idols. Similarly, if you're referring to 1 Cor. 10:14-21 & 27-30 where it says (NIV),
"Therefore, my dear friends, flee from idolatry. I speak to sensible people; judge for yourselves what I say. Is not the cup of thanksgiving for which we give thanks a participation in the blood of Christ? And is not the bread that we break a participation in the body of Christ? Because there is one loaf, we, who are many, are one body, for we all partake of the one loaf. Consider the people of Israel: Do not those who eat the sacrifices participate in the altar? Do I mean then that a sacrifice offered to an idol is anything, or that an idol is anything? No, but the sacrifices of pagans are offered to demons, not to God, and I do not want you to be participants with demons. You cannot drink the cup of the Lord and the cup of demons too; you cannot have a part in both the Lord’s table and the table of demons... If some unbeliever invites you to a meal and you want to go, eat whatever is put before you without raising questions of conscience. But if anyone says to you, “This has been offered in sacrifice,” then do not eat it, both for the sake of the man who told you and for conscience’ sake — the other man’s conscience, I mean, not yours. For why should my freedom be judged by another’s conscience? If I take part in the meal with thankfulness, why am I denounced because of something I thank God for?"
Then I still don't read Paul saying it is okay. Paul does seem to be undermining the admonition by leveraging the emptiness of idols and the individual's conscience but I don't read an explicit statement making it acceptable. He also implies that giving thanks to the one true God trumps the empty rituals to empty idols. So, if I've missed a text then please cite it before we continue.
