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.Have you so recently left idol worship? Materially it is NOTHING DIFFERENT FROM WHAT YOU HAVE ALWAYS EATEN. The method of slaughter is exactly the same.
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. But food does not bring us near to God; we are no worse if we do not eat, and no better if we do.
--I Cor 8:4-8
The Believers Freedom
23Everything is permissiblebut not everything is beneficial. Everything is permissiblebut not everything is constructive. 24Nobody should seek his own good, but the good of others.
25Eat anything sold in the meat market without raising questions of conscience, 26for, The earth is the Lords, and everything in it.c
27If some unbeliever invites you to a meal and you want to go, eat whatever is put before you without raising questions of conscience. 28But 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 saked
