In 1525, the magistracy of Zurich established a so-called State Church. Under the regulations of this Church, no preaching could be permitted within the territory of the city other than the pure Gospel of Zwingli and his associates. The books of worship of the Catholics were ordered to be delivered and burned and a similar course was taken with the Lutheran Bibles and the Lutheran works of instruction of Melanchthon. A similar action was taken in Geneva under the direction of Calvin. The altars and altar pictures were destroyed and the Catholics were ordered to deliver for like destruction their books of worship, of song, and their catechism. The Inquisition established in Geneva assumed the authority to visit houses and shops and to confiscate for destruction all heretical books. In 1539, the magistrates ordered that no book should be printed until it had received a license from the authorities. This decree was renewed in 1556 and in 1560. The burning of Servetus, under the authority of the court instituted by Calvin, occurred in 1553. In 1554, Calvin published his _Defensio Orthodoxi et Fidei de S. Trinitate contra Prodigiosos Errores Mich. Serveti Hispanii_, etc. This “Defence” bears, in addition to the name of the author, the subscriptions of fifteen of the divines of the Geneva Church. Later, Calvin called the theologians of Basel to account for permitting the publication of an anonymous monograph written as an answer to his “Defence,” and demanded that the publishers of the same should be duly punished. Even after the death of Calvin (1564), the censorship system was renewed and continued.[71]
