1 Corinthians 8:7-9

But not everyone possesses this knowledge. Some people are still so accustomed to idols that when they eat sacrificial food they think of it as having been sacrificed to a god, and since their conscience is weak, it is defiled. But food does not bring us near to God; we are no worse if we do not eat, and no better if we do. Be careful, however, that the exercise of your rights does not become a stumbling block to the weak.
