1 Corinthians 8:11-13

8:11 So by your knowledge the weak brother or sister, for whom Christ died, is destroyed. 8:12 If you sin against your brothers or sisters in this way and wound their weak conscience, you sin against Christ. 8:13 For this reason, if food causes my brother or sister to sin, I will never eat meat again, so that I may not cause one of them to sin.
