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.
