In 1524 Zwingli began to effect the most sweeping changes with the view of overthrowing the whole fabric of mediæval superstition. In the direction of reform he went far beyond Luther, who had retained oral confession, altar pictures, &c. The introduction of his reforms in Zurich called forth but little opposition. True, there were the risings of the Anabaptists but these were the same everywhere, and the revolt of the peasants was a general feature of the time.[51] Pictures and images were removed from the churches, under government direction, and nothing was left to distract men's attention, for Zwingli aimed at the re-establishment of the primitive Christianity in its pure, simple, and biblical form. The Holy Scriptures, expounded by the elect ministers of God, were to be men's highest guide and support. At the Landgemeinden,[52] called for the purpose, the people gave an enthusiastic assent to his doctrines, and declared themselves ready "to die for the gospel truth." Thus a national Church was established, severed from the diocese of Constance, and placed under the control of the Council of Zurich and a clerical synod. The convents were turned into schools, hospitals, and poor-houses. The famous Chorherrenstift, founded by the Carolingians, was turned into a University College, continuing to be called the Carolinum. This lasted till 1832, when it was formed into the University and Gymnasium of our own days. Zwingli was elected rector, and lectured on theology. He was also devoted to the study of Greek, and on New Year's Day, 1531, had a splendid performance of one of the plays of Aristophanes, for which he himself wrote the accompanying music, grave statesmen joining the professors and students in the representation. Zwingli was now, indeed, the idol of the people, and wielded the sceptre in his little state. Under him Zurich became a centre of learning and religious enlightenment, and its influence spread over other Swiss lands, South Germany and elsewhere. The reformed faith penetrated, but only gradually, into the northern and eastern cantons. Bern was reached in 1528, after a brilliant disputation held in that city. Basel and Schaffhausen followed in 1529, and then St. Gall, Appenzell, Graubünden, and Solothurn, though some of them had serious struggles within themselves and fell in only partly with the reforms. But in the Central or Forest Cantons it was that the fiercest opposition was encountered. Many things combined to produce this result. In the first place, the district was a very stronghold of Catholic and Conservative feeling, and religion was entwined with the fond memories of a glorious past. From the very simplicity of their lives the people ignored the degeneracy of the priesthood, and amongst these pastoral peoples the priests were of simpler manners and more moral life than those in the cities; they disliked learning and enlightenment.
