Romans 14:1 - Joseph Benson’s Commentary on the Old and New Testaments

Him that is weak in the faith Whose conscience is scrupulous, or whose mind is doubtful, unsatisfied in, or not well acquainted with the principles of Christianity; particularly that concerning Christian liberty and freedom from the ceremonial law. “The apostle means the Jewish Christian, who, through weakness of understanding, or through prejudice, was ignorant of the doctrine of the gospel concerning meats and days; or whose persuasion of that doctrine was so weak, that it did not influence his conduct. To such persons, though in error, the apostle showed great tenderness, when he represented them as only weak in faith.” Receive ye With all love and courtesy, into Christian fellowship: but not to doubtful disputations About questionable points. “The force of the apostle's admirable reasoning, in favour of candour and mutual condescension, cannot be enervated by saying, as some have done, that here was no separation between Jewish and Gentile Christians. For had the things judged indifferent by the latter, and apprehended sinful by the former, been imposed, a separation of communion must have ensued, and the schism, on the apostle's principles, would have been chargeable on the imposers.” Doddridge.
