CLV(i)
9 Now beware lest somehow this right of yours may become a stumbling block to the weak.
10 For if anyone should be seeing you, who has knowledge, lying down in an idol's shrine, will not the conscience of him who is weak be inured to the eating of the idol sacrifices?
11 For the weak one is perishing also by your knowledge; the brother because of whom Christ died.
12 Now in thus sinning against brethren, and beating their weak conscience, you are sinning against Christ."
