9. Only be careful that this power of choice (this permission and liberty to do as you please) which is yours, does not [somehow] become a hindrance (cause of stumbling) to the weak or overscrupulous [giving them an impulse to sin].
10. For suppose someone sees you, a man having knowledge [of God, with an intelligent view of this subject and] reclining at table in an idol's temple, might he not be encouraged and emboldened [to violate his own conscientious scruples] if he is weak and uncertain, and eat what [to him] is for the purpose of idol worship?
11. And so by your enlightenment (your knowledge of spiritual things), this weak man is ruined (is lost and perishes)–the brother for whom Christ (the Messiah) died!
12. And when you sin against your brethren in this way, wounding and damaging their weak conscience, you sin against Christ.
13. Therefore, if [my eating a] food is a cause of my brother's falling or of hindering [his spiritual advancement], I will not eat [such] flesh forever, lest I cause my brother to be tripped up and fall and to be offended.
