1 Corinthians 8:7

but that we write to them that they abstain from things contaminated by idols and from sexual immorality and from what is strangled and from blood.

I know and am convinced in the Lord Jesus that nothing is defiled in itself; but to him who considers anything to be defiled, to him it is defiled.

But I myself am also convinced about you, my brothers, that you yourselves are full of goodness, having been filled with all knowledge and being able also to admonish one another.

Now concerning things sacrificed to idols, we know that we all have knowledge. Knowledge puffs up, but love builds up.

Therefore, concerning the eating of things sacrificed to idols, we know that an idol is nothing in the world, and that there is no God but one.

However, not all men have this knowledge; but some, being accustomed to the idol until now, eat food as if it were sacrificed to an idol; and their conscience, being weak, is defiled.

For if someone sees you, who have knowledge, dining in an idol’s temple, will not his conscience, if he is weak, be built up to eat things sacrificed to idols?

For through your knowledge he who is weak is ruined, the brother for whose sake Christ died.

Eat anything that is sold in the meat market without asking questions for conscience’ sake.

But if anyone says to you, “This is meat consecrated to idols,” do not eat it, for the sake of the one who informed you, and for conscience’ sake.

And we urge you, brothers, admonish the unruly, encourage the fainthearted, help the weak, be patient with everyone.
