For if others see you, who possess knowledge, eating in the temple of an idol, might they not, since their conscience is weak, be encouraged to the point of eating food sacrificed to idols?
So by your knowledge those weak believers for whom Christ died are destroyed.
References for 1 Corinthians 8:11
But when you thus sin against members of your family, and wound their conscience when it is weak, you sin against Christ.
