When, in 1525, Munzer and his associates (commonly known as the prophets of Zwickaw) claimed divine authority, Luther was foremost in denouncing and persecuting them, and their followers. According to Mosheim, their principal crimes were in denying infant baptism and the right of a distinct class to preach for hire; and asserting that "God still continued to reveal His will to chosen persons by dreams and visions." (See Mosheim Vol. II, p. 128.) They also claimed "that God in His own good time would erect to Himself a holy church possessing a perfect organization, and would set apart for the execution of this grand design, a certain number of chosen instruments divinely assisted and prepared for this chosen work, by the aid and inspiration of His Holy Spirit." As a consequence they claimed the right to rebaptizing persons coming from other churches.
Mosheim further admits, "The extreme difficulty of correcting or influencing by the prospect of suffering, or even by the terrors of death, minds that are firmly bound by the ties of religion. In almost all the countries of Europe, an unspeakable number of those unhappy people preferred death, in its worst forms, to a retraction of their opinions. Neither the view of the flames that were kindled to consume them, nor the ignominy of the gibbet, nor the terrors of the sword, could shake their invincible constancy or make them abandon tenets that appeared dearer to them than life itself and all its enjoyments." (See Mosheim Vol. II, p. 131.)
To this sect and its principles Luther was bitterly opposed, but this opposition argues nothing in his favor, nor does it strengthen his authority. It may also be added that if Rome had divine authority, Luther had no right to secede from her. But if, as Luther claimed, she had through apostasy lost her authority, then, it may be asked, From whence did Luther receive his authority? In all this, Luther's actions were indeed logical, but fatal to the claims of modern sectarians who profess to be the ministers of Christ.
Luther was simply the battle-ax of God to hew down the edifice of popery which stood in the way of human progress. The churches, which, under the leadership of Luther, Melanchthon, Zwingle, Calvin, Knox and Henry VIII. of England, separated from Rome received the name of Protestant. And this very name implies that they were merely a protest against Rome, her teachings and authority. The right of protesting being once granted, it follows that others, also, have the right to protest against them. This principle caused the long and bloody wars which were only closed by the peace of Westphalia, in 1648, and then it was found that central and northern Europe had cast off the intellectual tyranny of Rome, and had established the right of every man to think for himself.
The Protestant party having thus established its existence, by protest and separation, was obliged to submit to the operation of the same principles. A decomposition into many rival sects was inevitable. These having no central or controlling authority, and no longer in fear of their great Roman adversary, commenced bitter warfares on each other; Lutherans persecuted Catholics and Catholics persecuted Protestants, and they in turn persecuted Puritans. Even Calvin proved the darkness of his own mind when he put to death the celebrated philosopher and physician, Michael Servetus, whose greatest crimes were that in religion he denied that the Father, the Son and the Holy Ghost were one and the same person; and in science he had partially succeeded in discovering the circulation of the blood. The circumstances also were of the most atrocious character. For two hours he was roasted in the flames of a slow fire, begging for the love of God that they would put on more wood, or do something to end his torture.
Yet the death of Servetus was not without advantage to the world. Men asked with amazement and indignation if the atrocities of the Inquisition were again to be revived. They saw at once that intolerance was not confined to the Romish church.
In spite of all these commotions, science was making rapid progress. Copernicus lived at the same time as Luther and died two years before him. His was as brave a life as ever lived in story. For thirty-six years—at the very time the Protestant struggle was raging—he was working at that immortal book, in which he so clearly demonstrates the motions of the earth and the revolutions of the planets around the sun. But he did not dare to publish it until there was a lull in the political storm. He was then an old man in broken health. His book was in the printer's hands when he was on his death bed. He waited at death's door from day to day. At length the messenger arrived with the printed book. He received it with tears in his eyes, composed himself and died.
Copernicus was followed by Tycho Brahe, Kepler and Galileo, and last, but by no means least, Isaac Newton, that scientific giant, who burst through the fetters of the ages, and taught man the laws, harmony and grandeur of the Creator's works.
During these troublous times Leonardo da Vinci wrote his celebrated works on mathematics and natural philosophy; and the arts of painting, sculpture and music were greatly improved under the direction of Titian, Corregio, Michael Angelo and Filippo Neri. A few years later Bruno wrote his work on the plurality of worlds.
Copernicus having died soon after the publication of his works, was beyond the reach of his persecutors. Galileo was brought before the Inquisition, and after years of imprisonment, only saved his life by denying the great truths he had discovered. But Bruno heroically refused to recant, and was tortured to death February 16th, 1700, a martyr to the cause of truth.
