Bible: 1 Cor 8:7-9
8:7 But this knowledge is not shared by all. And some, by being accustomed to idols in former times, eat this food as an idol sacrifice, and their conscience, because it is weak, is defiled. 8:8 Now food will not bring us close to God. We are no worse if we do not eat and no better if we do. 8:9 But be careful that this liberty of yours does not become a hindrance to the weak.
