1 Corinthians 8:9

7However, that knowledge isn’t in all men. But some, with consciousness of an idol until now, eat as of a thing sacrificed to an idol, and their conscience, being weak, is defiled.

8But food will not commend us to God. For neither, if we don’t eat are we the worse, nor if we eat are we the better.

9But be careful that by no means does this liberty of yours become a stumbling block to the weak.

10For if a man sees you who have knowledge sitting in an idol’s temple, won’t his conscience, if he is weak, be emboldened to eat things sacrificed to idols?

11And through your knowledge, he who is weak perishes, the brother for whose sake Christ died.
