John Calvin: . "Some unskilful persons, from not attending to this, boldly discard the whole law of Moses, and do away with both its Tables, imagining it unchristian to adhere to a doctrine which contains the ministration of death. Far from our thoughts be this profane notion."
John Wesley: "In the highest rank of the enemies of the gospel of Christ, are they who openly and explicitly 'judge the law' itself, and 'speak evil of the law;' who teach men to break (to dissolve, to loose, to untie the obligation of) not one only, whether of the least or of the greatest, but all the commandments at a stroke. . . . The most surprising of all the circumstances that attend this strong delusion, is that they who are given up to it, really believe that they honor Christ by overthrowing His law, and that they are magnifying His office while they are destroying His doctrine! Yea, they honor Him just as Judas did when he said, 'Hail, Master, and kissed Him.' And He may as justly say to every one of them, 'Betrayest thou the Son of man with a kiss? It is no other than betraying Him with a kiss, to talk of His blood, and take away His crown; to set light by any part of His law, under pretense of advancing His gospel. Nor indeed can anyone escape this charge, who preaches faith in any such a manner as either directly or indirectly tends to set aside any branch of obedience: who preaches Christ so as to disannul, or weaken in any wise, the least of the commandments of God."
Martin Luther: "Nowadays there is a novel idea afoot! According to the promoters of this idea, the Law (that is, the 10 Commandments) should be completely removed from the Church. This is nothing else but deplorable and irreverent.
The entire Bible teaches that it is the Law which must initiate repentance.....Sin and death are not exposed by a Word of grace and comfort, but only by the Law."
