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.
