1 Corinthians 8:9-12

9But 1take care that this 2freedom of yours does not somehow become a stumbling block to the 3weak.

10For if someone sees you, the one who has 4knowledge, dining in an idol’s temple, will his conscience, if he is weak, not be strengthened to eat 5things sacrificed to idols?

11For through 6your knowledge the one who is weak 7is ruined, the brother or sister for whose sake Christ died.

128And so, by sinning against the brothers and sisters and wounding their conscience when it is weak, you sin 9against Christ.
