Flushed with his triumph Zwingli now proceeded to put his theories into practice. Supported by a mob he endeavoured to prevent the celebration of Mass, religious processions, the use of pictures and statues, and the solemn ceremonial associated with Extreme Unction and the Viaticum. He compiled an introduction to the New Testament for the use of the clergy, called upon them to abandon their obligations of celibacy, and set them an example by taking as his wife a woman who had been for years his concubine. He and his followers, supported by the majority of the Grand Council, went through the city destroying altars, pictures, statues, organs, and confessionals, and erecting in place of the altars plain tables with a plate for bread and a vessel for wine. The Catholic members of the Grand Council were driven from their position, and Catholic worship forbidden in Zurich (1523-5).
The system of Zwingli was much more rationalistic and, in a certain sense, much more logical than that of Luther. Imbued with the principles of pantheistic mysticism, he maintained that God is in Himself all being, created as well as uncreated, and all activity.
Hence it was as absurd to speak of individual liberty or individual action as to speak of a multiplicity of gods. Whether it was a case of doing good or doing evil man was but a machine like a brush in the hands of a painter. In regard to sin he contended man may be punished for violating the law laid down by God even though the violation is unavoidable, but God, being above all law, is nowise to blame.
Concupiscence or self-love is, according to him, at the root of all misdeeds. It is in itself the real original sin, and is not blotted out by Baptism. His teaching on the Scriptures, individual judgment, ecclesiastical authority as represented by the bishops, councils, and Pope, good works, indulgences, purgatory, invocation of the saints, and vows of chastity differed but slightly from what Luther had put forward. On the question of Justification, and particularly on the doctrine of the Eucharist, the two reformers found themselves in hopeless conflict.[3]
Zwingli's teaching did not at first find much favour in other portions of German Switzerland. Lucerne declared against it in 1524. The city authorities forbade the introduction of the new teaching, and offered an asylum to those Catholics who had been forced to flee from Zurich.
Other cantons associated themselves with Lucerne, and a deputation was sent to Zurich to request the city authorities to abandon Zwingli and to take part in a general movement for a real and constitutional reform. But the Grand Council, mindful of the political advantages which would accrue to Zurich from its leadership in the new religious revolt, declined to recede from their position.
While Zwingli was at work in Zurich, Oecolampadius (1482-1531) set himself to stir up religious divisions in Basle. He was born at Weisnberg, studied law at Bologna and theology subsequently at Heidelberg, was ordained priest, and appointed to a parish in Basle (1512). With Erasmus he was on terms of the closest intimacy, and, as Basle was then one of the great literary centres of the world, he soon became acquainted with Luther's pamphlets and teaching. Some of the clergy in Basle, notably Wolfgang Capito, a warm friend of Zwingli, were already showing signs of restlessness especially in regard to the Mass, purgatory, and invocation of the saints, and Oecolampadius was not slow to imbibe the new ideas. In 1518 he was appointed preacher in the Cathedral of Augsburg, but, having resigned this office on account of failing health, he withdrew to the convent of Altmunster, where, for some time, he lived a retired life. Subsequently he acted as chaplain to the well-known German knight, Franz von Sickingen, and finally, in 1524, he accepted the parish of St. Martin's in Basle.
He now proclaimed himself openly a supporter of Zwingli, advocated the new teaching on justification and good works, and attacked several Catholic doctrines and practices. For him, as indeed for most of the other reformers, clerical celibacy was the great stumbling block. He encouraged his followers by taking as his wife a young widow, who was subsequently in turn the wife of the two renowned Lutheran preachers, Butzer and Capito. At first the city authorities and a large body of the university professors were against him, but owing to the disturbances created by his partisans full liberty of worship was granted to the new sect (1527). Not content with this concession, they demanded that the Mass should be suppressed. In 1529 the followers of Oecolampadius rose in revolt, seized the arsenal of the city, directed the cannon on the principal squares, and attacked the churches, destroying altars, statues, and pictures. Erasmus, disgusted with such methods of propagating religion, left Basle and sought a home in Freiburg. The Catholics were expelled from the city council, their religion was proscribed, and Basle joined hands with Zurich in its rebellion against the Church.
The revolt soon spread into other cantons of Switzerland. In Berne and Schaffhausen both parties were strong and determined, and for a time the issue of the conflict was uncertain, but in 1528 the party of Zwingli and Oecolampadius secured the upper hand. Similarly in St.
Gall, Glarus, etc., victory rested with the new teaching. Other cantons, as for example, Solothurn, wavered as to which side they should take, but the three oldest cantons of Switzerland, Uri, Schweiz and Unterwalden, together with Zug, Freiburg and Lucerne, refused to be separated from the Church.
