WNT(i)
10 For if any one were to see you, who know the real truth of this matter, reclining at table in an idol's temple, would not his conscience (supposing him to be a weak believer) be emboldened to eat the food which has been sacrificed to the idol?
11 Why, your knowledge becomes the ruin of the weak believer--your brother, for whom Christ died!
12 Moreover when you thus sin against the brethren and wound their weak consciences, you are, in reality, sinning against Christ.
13 Therefore if what I eat causes my brother to fall, never again to the end of my days will I touch any kind of animal food, for fear I should cause my brother to fall.
