1 Corinthians 8:10-13

8:10 For if someone weak sees you who possess knowledge dining in an idol’s temple, will not his conscience be “strengthened” to eat food offered to idols? 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.

Romans 14:15

14:15 For if your brother or sister is distressed because of what you eat, you are no longer walking in love. Do not destroy by your food someone for whom Christ died.
