'Idol' in the Bible

About eating food offered to idols, then, we know that “an idol is nothing in the world,” and that “there is no God but one.”

However, not everyone has this knowledge. In fact, some have been so used to idolatry up until now that when they eat food offered to an idol, their conscience, being weak, is defiled.

What am I saying then? That food offered to idols is anything, or that an idol is anything?

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.
