1 Corinthians 8:11

“And through thy knowledge, etc.] These words contain an aggravation of the sin such persons are guilty of, who are the means, by their example, of ensnaring weak minds, and causing them to stumble and fall, even in some sense so as to perish: shall the weak brother perish, for whom Christ died? every word almost carries in it an exaggeration of this matter; it is not some slight injury that is done to the person, but even causing him to “perish”; and this is not said of any person, but a “brother”, to whom the strongest affection, and strictest regard, should be shown; and a “weak” brother, of whom the greater care should be taken; and therefore it is an instance of cruelty to do damage to…”

“shall . . . perish--The oldest manuscripts read "perisheth." A single act seemingly unimportant may produce everlasting consequences. The weak brother loses his faith, and if he do not recover it, his salvation [BENGEL] (Rom 14:23). for whom Christ died--and for whose sake we too ought to be willing to die (Jo1 3:16).

Scripture is our rule, not our suppositions as to consequences.…”

“And through thy knowledge - Because you knew that an idol was nothing, and that there could be really no danger of falling into idolatry from partaking of these entertainments. You will thus be the means of deceiving and destroying him. The argument of the apostle here is, that if This was to be the result, the duty of those who had this knowledge was plain. Shall the weak brother - The uninformed and ignorant Christian. That it means real Christian there can be no doubt. Because: (1) It is the usual term by which Christians are designated - the endearing name of “brother;” and, (2) The scope of the passage requires it so to be understood; see the note at Romans 14:20. Perish - Be destroyed;…”

“And through thy knowledge shall the weak brother perish, for whom Christ died? - And for whom thou wilt not lose a meal's meat, so far from dying for him! We see, Christ died even for them that perish. 1 Corinthians 8:12”

“8:11 For believers to insist on eating food offered to idols—because their superior knowledge assured them that they are free to eat such food—could destroy less mature Christians (who understood eating this meat as an expression of worship of pagan gods). • for whom Christ died: Cp. Rom 14:15.”
