Sebastian Castellio, a well-known preacher and Scriptural scholar, was punished because he could not agree with Calvin's teaching on predestination, as was also the physician Bolsec; Ameaux one of the members of the Council was put to death because he denounced the tyranny of Calvin and of the Consistory; Gentilis was condemned to execution for differing with Calvin's teaching on the Trinity, and was compelled to make a most abject public retraction before he could obtain a reprieve. Several of the citizens were punished with long imprisonment for dancing even on the occasion of a wedding, as happened in the case of Le Fevre, whose son-in-law was obliged to flee to France because he resented warmly such methods of promoting religion. In Geneva and in the adjoining territory all Catholic practices were put down by violence, and the peasants were allowed no choice in their religious views. Possibly, however, the most glaring example of Calvin's tyranny and high-handed methods was his treatment of Michael Servetus, a Spaniard who had written against the Trinity. He was on a journey through the territory of Geneva and was doing nothing to spread his doctrines nor acting in any way likely to bring him under the ire of Calvin. The latter having heard of his presence there had him arrested, tried, and condemned to death. To justify such harshness he published a pamphlet in which he advocated death as the only proper remedy for heresy. Theodore Beza wrote strongly in support of this opinion of his master's, as did also Melanchthon who, though differing from Calvin on so many points, hastened to forward his warmest congratulations on the execution of Servetus.[3] Calvin's acts of cruelty were not the result of violent outbursts of temper. By nature cold and immovable, he did not allow himself to be hurried to extremes either by anger or by passion. How he succeeded in maintaining his position for so many years in Geneva is intelligible only to those who understand the strength of the religious fanaticism that he was able to arouse amongst his followers, the terror which his spiritual and temporal punishments inspired among his opponents, his own wonderful capacity for organisation and administration, the activity of his ministers and spies, and the almost perfect system of repression that he adopted in his two-fold character of religious and political dictator.
