1 Corinthians 8
10 Ref For 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?
11 Ref And through your knowledge, he who is weak perishes, the brother for whose sake Christ died.
12 Ref Thus, sinning against the brothers, and wounding their conscience when it is weak, you sin against Christ.
