I Corinthians 8:8-13

But food does not commend us to God; for neither if we eat are we the better, nor if we do not eat are we the worse. But beware lest somehow this liberty of yours become a stumbling block to those who are weak. For if anyone sees you who have knowledge eating in an idol’s temple, will not the conscience of him who is weak be emboldened to eat those things offered to idols? And because of your knowledge shall the weak brother perish, for whom Christ died? But when you thus sin against the brethren, and wound their weak conscience, you sin against Christ. Therefore, if food makes my brother stumble, I will never again eat meat, lest I make my brother stumble.
