Ulrich, or Huldrych, Zwingli of Zürich is the 'great unknown' of the Reformation in Europe, and yet his influence and ideas have penetrated into every part of the world where the Reformed tradition has been planted. He was neither a passionate man of religion like Luther, nor a superb dialectician like Calvin. But in his lucid radicalism and belief in thorough reform in Church doctrine as well as in government, Zwingli stands with his two more famous brethren as a 'Father of the Reformation'. First published in English in 1964, Jean Rilliet's biography places Zwingli in the context of Swiss church history, as well as that of the sixteenth-century upheaval of which he was a part. Covering every aspect of Zwingli's career, with detailed discussion of his more influential writings, the picture that emerges is one of a 'fighting prophet', unremittent in his search for God in this most turbulent of times.
