Luther was violently opposed to the scientific movement. He called Copernicus an old fool. He would hear nothing against the accepted Biblical theory of the universe. Genesis was to him, as well as to the Pope, the beginning and the end of sound science. Nor was he more friendly to philosophy. Draper truly asserts that the leaders of the Reformation "were determined to banish philosophy from the Church." Aristotle was villified by Luther as "truly a devil, a horrid calumniator, a wicked sycophant, a prince of darkness, a real Apollyon, a beast, a most horrid impostor on mankind, a public and professed liar, a goat, a complete epicure, this twice execrable Aristotle." Such was Luther's style in controversy. We commend it to the attention of Protestants who rail at the _Freethinker_. Liberty of conscience is a principle of which Luther had no conception. He claimed the right to think against the Pope; he denied the right of others to think against himself. His attitude towards the Anabaptists was fiendish. During the Peasants War he urged the authorities to exterminate the rebels, to "stab, kill, and strangle them without mercy." Melancthon taught that heretics "ought to be restrained by the sword." Luther likewise declared that whoever denied even one article of the Protestant faith should be punished severely. Referring to a false teacher, he exclaimed, "Drive him away as an apostle of hell; and if he does not flee, deliver him up as a seditious man to the executioner." Hallam, Buckle, Lecky, and all reputable historians, agree that the Protestant party held the same principle of persecution as the Catholics. It was not disputed that death was the proper punishment of obstinate heresy. The only dispute was--which were the heretics, and who should die? Luther's influence was very great in England, as Calvin's was in Scotland, and the leaders of the Reformation in our own country had no doubt as to the justice of killing men for a difference of opinion. Cranmer taught that heretics were first to be excommunicated; if that made no impression on them they were to suffer death. It satisfies one sense of the fitness of things that Cranmer himself perished at the stake. Becon taught that the duty of magistrates with regard to heretics was to punish them--"yea, and also to take them out of this life." This same Becon called upon the temporal rulers to "be no longer the pope's hangmen." He preferred their being the hangmen of Protestantism. Latimer himself said of the Anabaptists who were executed, "Well, let them go!" Bishop Jewel, the great apologist of the Protestant Church of England, in answering Harding the Jesuit, replies in this way to the charge of being of the brotherhood of Servetus, David George, and Joan of Kent: "We detected their heresies, and not you. We arraigned them; we condemned them. We put them to the execution of the laws. It seemeth very much to call them our brothers, because we burnt them."
