Major reformer in the Protestant Reformation in Switzerland.
Educated in Vienna and Basel, he was ordained a priest in 1506. An admirer of Martin Luther made his break with the church in Rome, and became increasingly active in challenging the ritualism, decadence, and hierarchy of the Roman Catholic church. The main contentions of his 67 Articles (1523) were adopted by most priests in Zürich. As his movement spread, he rejected a number of the basic teachings of the church, declaring that Jesus alone is head of the church, that the mass is an affront to Christ, and that there is no biblical foundation for the intercession of the dead or for {{link=purgatory">purgatory . He also rejected the notions of priestly celibacy, and his teachings on the sacrament of communion brought him into conflict with both Luther and the Catholic church. He was killed in a battle between Protestants and Catholics while serving as an army chaplain.
