1 Corinthians 8:8-13

But food will not commend us to God: neither, if we eat not, are we the worse; nor, if we eat, are we the better. But take heed lest by any means this liberty of yours become a stumblingblock to the weak. For if a man see thee who hast knowledge sitting at meat in an idol’s temple, will not his conscience, if he is weak, be emboldened to eat things sacrificed to idols? For through thy knowledge he that is weak perisheth, the brother for whose sake Christ died. And thus, sinning against the brethren, and wounding their conscience when it is weak, ye sin against Christ. Wherefore, if meat causeth my brother to stumble, I will eat no flesh for evermore, that I cause not my brother to stumble.
