9 But take care that this power of yours does not give cause for trouble to the feeble.
10 For if a man sees you, who have knowledge, taking food as a guest in the house of an image, will it not give him, if he is feeble, the idea that he may take food offered to images?
11 And so, through your knowledge, you are the cause of destruction to your brother, for whom Christ underwent death.
12 And in this way, doing evil to the brothers, and causing trouble to those whose faith is feeble, you are sinning against Christ.
13 For this reason, if food is a cause of trouble to my brother, I will give up taking meat for ever, so that I may not be a cause of trouble to my brother.
