We may suppose that the substance of this verse recurs to the Apostle’s mind after the parenthetical statement just inserted, and though he does not repeat it in words, he connects on to it the sequence of his thought. “The Christian should not put a stumbling-block in his brother’s way. Not, indeed, that there is anything unclean in itself, but relatively to the person who so regards it. it is unclean. [Therefore the Christian should be careful as to what he does.] For to cause distress to another about a mere matter of food is to be uncharitable.”

The work of redemption that Christ has wrought for him is cancelled, and all that great and beneficent scheme is hindered of its operation by an act of thoughtlessness or want of consideration on the part of a fellow Christian.
