1 Corinthians 8:11-13

So, in effect, by exercising your understanding of freedom, you have ruined this weak believer, a brother for whom Christ has died! And when you offend weaker believers by wounding their consciences in this way, you also offend the Anointed One! So I conclude that if my eating certain food deeply offends my brother and hinders his advance in Christ, I will never eat it again. I don’t want to be guilty of causing my brother or sister to be wounded and defeated.
