apostolic succession, while others simply believe they were an independent group out of whom the Anabaptists arose. Ludwig Keller, Thomas M. Lindsay, Henry Clay Vedder, Delbert Grätz, John T. Christian and Thieleman J. van Braght (author of Martyrs Mirror) all held, in varying degrees, the position that the Anabaptists were of Waldensian origin. History Switzerland Anabaptism in Switzerland began as an offshoot of the church reforms instigated by Ulrich Zwingli. As early as 1522, it became evident that Zwingli was on a path of reform preaching when he began to question or criticize such Catholic practices as tithes, the mass, and even infant baptism. Zwingli had gathered a group of reform-minded men around him, with whom he studied classical literature and the scriptures. However, some of these young men began to feel that Zwingli was not moving fast enough in his reform. The division between Zwingli and his more radical disciples became apparent in an October 1523 disputation held in Zurich. When the discussion of the mass was about to be ended without making any actual change in practice, Conrad Grebel stood up and asked "what should be done about the mass?" Zwingli responded by saying the council would make that decision. At this point, Simon Stumpf, a radical priest from Höngg, answered saying, "The decision has already been made by the Spirit of God." This incident illustrated clearly that Zwingli and his more radical disciples had different expectations. To Zwingli, the reforms would only go as fast as the city Council allowed them. To the radicals, the council had no right to make that decision, but rather the Bible was the final authority of church reform. Feeling frustrated, some of them began to meet on their own for Bible study. As early as 1523, William Reublin began to preach against infant baptism in villages surrounding Zurich, encouraging parents to not baptize their children. Seeking fellowship with other reform-minded people, the radical group wrote letters to Martin Luther, Andreas Karlstadt, and Thomas Müntzer. Felix Manz began to publish some of Karlstadt's writings in Zurich in late 1524. By this time the question of infant baptism had become agitated and the Zurich council had instructed Zwingli to meet weekly with those who rejected infant baptism "until the matter could be resolved". Zwingli broke off the meetings after two sessions, and Felix Manz petitioned the council to find a solution, since he
