10 Suppose anyone sees you, a person of enlightened mind, reclining at meat inside an idol's temple; will that really 'fortify his weak conscience'? Will it not embolden him to violate his scruples of conscience by eating food that has been offered to idols?
11 He is ruined, this weak man, ruined by your 'enlightened mind,' this brother for whose sake Christ died!
12 By sinning against the brotherhood in this way and wounding their weaker consciences, you are sinning against Christ.
