'Idols' in the Bible

Now concerning food offered to idols: We know that we all possess knowledge. Knowledge puffs up, but love builds up.

Now concerning eating food offered to idols: We know that no idol is real in this world and that there is only one God.

For if anyone with a weak conscience sees you, who know better, eating in an idol's temple, he will be encouraged to eat what has been offered to idols, won't he?

Am I suggesting that an offering made to idols means anything, or that an idol itself means anything?

You know that when you were unbelievers, you were enticed and led astray to worship idols that couldn't even speak.
