But if thy brother be grieved with thy meat
The apostle proceeds to give reasons why, though he was so fully persuaded that nothing was unclean of itself, and so he, and any other of the same persuasion, might lawfully eat anything; yet they should forbear, and not make use of this liberty; because if a brother should be grieved by it, that is, either should be concerned and troubled at it inwardly, both because the person that eats is thought by him to have transgressed a command of God, and because he himself is not only despised as a weak brother, but as if he was a "judaizing" Christian, and walked not uprightly, according to the truth of the Gospel; or else should be emboldened thereby to eat, and so wound and defile his weak conscience; or be so galled and offended at it, as to stumble and fall off from his profession of Christianity, and withdraw his communion, as judging there is nothing in it, no regard being had to the law of God:
now walkest thou not charitably;
this is a breach of the rule of charity or brotherly love; such an one is a brother, and though a weak one, yet he is to be loved as a brother, and to be charitably walked with: true charity, or love, vaunts not itself over, nor is it puffed up against a weak brother; nor is it unconcerned for his peace, but bears with his weaknesses, and forbears the use of things grieving to him:
destroy not him with thy meat, for whom Christ
This is to be understood, not of eternal destruction, that can never be thought to be either in the will or power of any man; such a degree of malice can never arise in the heart of any, to wish for, desire, or take any step towards the eternal damnation of another; and could any thing of this kind be among the men of the world, yet surely not among brethren of the same faith, and in the same church state; and were there any so wicked as to desire this, yet it is not in their power to compass it, for none can destroy eternally but God; see ( Matthew 10:28 ) ; besides, it is not reasonable to suppose, that eternal damnation should follow upon eating things indifferent, or be caused by an offence either given or taken through them; moreover, though such as only think themselves, or profess themselves, or are only thought by others to be such, for whom Christ died, may be eternally destroyed, yet none of those can, for whom Christ really died; for they are his special people, his peculiar friends, his own sheep, his body the church, which can never perish; and he, by dying, has procured such blessings for them, such as a justifying righteousness, pardon of sin, peace with God, and eternal life, which will for ever secure them from destruction: besides, should anyone of them be destroyed, the death of Christ would be so far in vain, nor would it appear to be a sufficient security from condemnation, nor a full satisfaction to the justice of God; or God must be unjust, to punish twice for the same fault: but this is to be understood of the destruction of such a man's peace and comfort, which is signified by grieving, stumbling, offending, and making him weak; and the words are a fresh reason, why they that are strong in the faith of Christian liberty, should nevertheless forbear the use of it, to preserve the peace of a weak brother; which is a matter of importance, and the rather to be attended to, since it is the peace of one that belongs to Christ, whom he has so loved as to die for, and therefore should be the object of the regard and affections of such as believe in Christ and love him.
