'Idol' in the Bible

As concerning therefore the eating of those things that are offered in sacrifice unto idols, we know that an idol is nothing in the world, and that there is none other God but one.

Howbeit there is not in every man that knowledge: for some with conscience of the idol unto this hour eat it as a thing offered unto an idol; and their conscience being weak is defiled.

However, food will not bring us closer to God. We are no worse off if we do not eat food that has been offered to an idol, and no better off if we do.

For if any one see thee, who hast knowledge, sitting at table in an idol-house, shall not his conscience, he being weak, be emboldened to eat the things sacrificed to the idol?

What say I then? that the idol is any thing, or that which is offered in sacrifice to idols is any thing?

But if someone says to you, “This is food offered to an idol,” do not eat it, out of consideration for the one who told you, and for conscience’ sake.
