Moreover, if thy brother shall trespass against thee,.... This is said to show, that as on the one hand, if any of those that believe in Christ, should commit a trespass against his fellow Christian, his sin is not to be connived at, for fear of offending him; for what Christ has before said, is not to be taken in such sense, as to prevent private reproof, or public censures, when there is occasion for them; so on the other hand, he is not to be despised and ill used, and treated in the same injurious manner; but gentle reproofs are to be made use of, for his good.
This is spoken not to the apostles as such, but as believers in Christ; and concerns everyone that stands in the relation of a brother, or church member to each other, and only such; for they that are without, do not fall under their notice, nor are they obliged to take, nor can they take altogether, the same methods with them.
