In this episode of pplpod, we explore the life of Huldrych Zwingli, the Swiss theologian and reformer whose challenge to Catholic authority helped launch the Swiss Reformation. The story begins in Zurich in 1522, when a group of men deliberately ate smoked sausages during Lent, openly violating the Church’s fasting rules. Zwingli defended their actions from the pulpit, arguing that religious obligations must be grounded in scripture rather than imposed by church authorities. Born in 1484 in Wildhaus, Switzerland, Zwingli was educated in Vienna and Basel, influenced by Renaissance humanism, and ordained as a Catholic priest in 1506. His early career included serving as a military chaplain to Swiss mercenaries fighting for the pope, but witnessing the slaughter at the Battle of Marignano in 1515 transformed his views on warfare, religious authority, and the relationship between church and state.

The episode follows Zwingli’s rise as a preacher at Zurich’s Grossmünster, where he abandoned traditional assigned readings and began preaching directly through the Bible, chapter by chapter. After surviving the devastating plague of 1519, he became increasingly determined to reform the Church. His defense of religious freedom during the Affair of the Sausages, his marriage to Anna Reinhardt, and his 67 Articles brought him into direct conflict with Catholic authorities. With the support of Zurich’s city council, he oversaw the removal of religious images, the dissolution of monasteries, the redistribution of church wealth for social welfare, and the replacement of elaborate Catholic worship with simpler, scripture-centered services. Yet his revolution carried troubling contradictions. Zwingli supported the persecution of Anabaptists who rejected infant baptism, clashed bitterly with Martin Luther over the meaning of the Lord’s Supper, and ultimately supported increasingly aggressive policies against Catholic cantons. In 1531, the man whose opposition to war had helped inspire his reforms died on the battlefield at Kappel. His ideas survived through Heinrich Bullinger, John Calvin, and the development of the Reformed Protestant tradition.
