Ulrich Zwingli

Ulrich Zwingli was born on January 1, 1484, in Wildhaus, a village in the Toggenburg valley of eastern Switzerland, then part of the Old Swiss Confederacy ^[1]. His birth came just seven weeks after that of Martin Luther, a coincidence later writers often noted when comparing the two reformers. His father, also named Ulrich, was a prosperous farmer who served as the local magistrate, and the family could afford a serious education for a promising son ^[2].

The boy's schooling began under his uncle Bartholomew, a priest at Weesen, before he moved on to Latin schools in Basel and Bern. In Bern his musical talent attracted the attention of the Dominicans, who tried to recruit him for their order, but his family withdrew him rather than see him become a friar ^[1]. He enrolled at the University of Vienna around 1498 and then completed his studies at the University of Basel, taking a bachelor of arts in 1504 and a master of arts in 1506 ^[2].

Basel proved decisive for his intellectual formation. There he absorbed the humanist program of returning to original texts, and he encountered the teaching of Thomas Wyttenbach, who encouraged critical questions about indulgences and the authority of scholastic theology. Anyone asking who was Ulrich Zwingli before the Reformation finds a young scholar shaped less by monastic piety than by Renaissance humanism and the study of classical languages ^[3].

Ordained a priest in 1506, Zwingli took up his first parish in Glarus, where he remained for a decade ^[1]. The post carried an unusual duty: Glarus supplied mercenary soldiers to foreign powers, and Zwingli twice accompanied its troops to Italy as chaplain, witnessing the carnage at the Battle of Marignano in 1515. The experience turned him into a vocal critic of the mercenary trade, a stance that made him enemies among local families who profited from French pensions ^[2].

In 1516 he moved to Einsiedeln, a Benedictine abbey and one of the most visited pilgrimage sites in the Confederacy. Preaching to crowds of pilgrims, he began questioning practices he considered unsupported by scripture, including the veneration offered at the shrine itself ^[4]. During these years he taught himself Greek, corresponded with Erasmus of Rotterdam, and studied the Greek New Testament that Erasmus published in 1516, reportedly copying out the Pauline epistles by hand to memorize them ^[3].

His reputation as a preacher and scholar earned him election as people's priest at the Grossmünster in Zurich, where he began work on January 1, 1519, his thirty fifth birthday ^[1]. He immediately broke with custom by abandoning the prescribed lectionary and preaching straight through the Gospel of Matthew, chapter by chapter, in the language of his hearers. Later that year plague struck Zurich and killed roughly a quarter of the population; Zwingli stayed to minister to the sick, nearly died of the disease himself, and recorded the ordeal in a set of verses known as his plague song ^[4].

The public break with the old church began over a plate of sausage. During Lent in 1522, the printer Christoph Froschauer and his workers ate meat in deliberate violation of the fasting rules, with Zwingli present though not eating. When the city arrested Froschauer, Zwingli defended the act in a sermon and pamphlet arguing that scripture nowhere commanded the Lenten fast, an event remembered as the Affair of the Sausages ^[2]. Later that year he petitioned the bishop of Constance to permit clerical marriage, and he secretly married Anna Reinhart, a widow, around the same time ^[1].

The decisive contest came in January 1523, when the Zurich council convened a public disputation. Zwingli prepared sixty seven articles, or theses, defending justification by faith, attacking the papacy, the Mass as sacrifice, the intercession of saints, and compulsory fasting ^[4]. The council ruled that he could continue preaching, effectively placing religious authority in the hands of the civic government rather than the bishop. A second disputation in October 1523 addressed images and the Mass, and over the following two years Zurich removed statues and paintings from its churches in an orderly, council supervised fashion ^[2].

Among the central Ulrich Zwingli achievements was the abolition of the Latin Mass in Zurich in April 1525, replaced by a simple communion service in German with worshippers receiving bread and wine from wooden vessels ^[1]. He also helped organize the Prophezei, a daily gathering established in 1525 where clergy and students worked through the biblical text in Hebrew, Greek, and Latin. Out of this school of translation came the complete Zurich Bible, printed by Froschauer in 1531, several years before Luther finished his full German Bible ^[5].

Reform in Zurich generated radicals who thought Zwingli moved too slowly. Former associates including Conrad Grebel and Felix Manz rejected infant baptism, arguing that baptism belonged only to confessing adults, and in January 1525 they performed the first adult rebaptisms, founding the movement their opponents called Anabaptism ^[4]. Zwingli debated them publicly and wrote against them, and the Zurich council eventually made rebaptism a capital offense. Manz was executed by drowning in the Limmat river in January 1527, a punishment carried out with Zwingli's acquiescence and long counted among the darker Ulrich Zwingli facts ^[2].

A different conflict divided him from Martin Luther. Both men rejected the Catholic Mass, but they disagreed sharply on what happens in the Lord's Supper. Luther insisted that Christ's body and blood are truly present in the bread and wine, while Zwingli read the words of institution symbolically, holding that the meal is a memorial and pledge of faith ^[3]. Their pamphlet exchange grew bitter, and in October 1529 Landgrave Philip of Hesse brought them together at his castle in Marburg to negotiate a common Protestant front. The Marburg Colloquy produced agreement on fourteen of fifteen articles, but the two sides could not reconcile their views of the Supper, and the hoped for political alliance between the Swiss and German reformations collapsed ^[1].

The disagreement outlived both men. Zwingli's sacramental theology, later refined by Heinrich Bullinger and partially merged with John Calvin's views in the Consensus Tigurinus of 1549, became a defining mark separating Reformed churches from Lutheran ones ^[5].

Zwingli's private life mirrored the transitions of his age. As a young priest he admitted to lapses from his vow of celibacy, a failing common among clergy of the period, and he later argued that mandatory celibacy created hypocrisy and should be abolished ^[2]. His clandestine union with Anna Reinhart, begun in 1522, was made public in a church wedding in April 1524, only months before the birth of their first child. The couple had four children together, and Anna also brought three children from her first marriage to the innkeeper Hans Meyer von Knonau ^[1].

Contemporaries described Zwingli as sociable, quick in argument, and devoted to music. He played several instruments, including the lute and violin, yet he removed organs from Zurich's churches because he found no scriptural warrant for instrumental music in worship, a distinction between private enjoyment and public liturgy that puzzled some observers ^[4]. He kept up a wide correspondence, read voraciously in the classics, and cited Seneca and Plato alongside the prophets.

Unlike Luther, whose table talk and letters preserve a vivid personality, Zwingli left fewer intimate records, and his surviving writings are mostly polemical or exegetical. His household in Zurich nevertheless became a gathering point for reform minded clergy and refugees, and Anna Reinhart earned a reputation for hospitality toward exiles arriving in the city ^[5].

By the late 1520s the Swiss Confederacy had split along confessional lines. Zurich, Bern, Basel, and other reformed cities faced the five inner cantons (Lucerne, Uri, Schwyz, Unterwalden, and Zug), which remained Catholic and allied themselves with Ferdinand of Austria ^[1]. Zwingli, convinced that the gospel could not spread while the Catholic cantons blocked reformed preaching in the shared territories, pressed for a hard line. A first confrontation in June 1529, the First War of Kappel, ended without battle when negotiators arranged a peace, sealed according to tradition by soldiers of both sides sharing a large pot of milk soup on the frontier ^[2].

The settlement satisfied no one. Zurich imposed a food blockade on the inner cantons in 1531, hoping economic pressure would force them to admit Protestant preachers. Instead the Catholic cantons declared war and marched suddenly in October, catching Zurich unprepared ^[4]. On October 11, 1531, a hastily assembled Zurich force of perhaps 2,000 men met an army roughly three times its size at Kappel am Albis. The battle was a rout. Zwingli, serving as chaplain and carrying arms as custom required, was wounded and then killed on the field at the age of 47 ^[1].

The victors treated his corpse as that of a heretic and traitor: it was quartered and burned, the ashes mixed with dung and scattered so that no relics could remain ^[3]. The Second Peace of Kappel that followed froze the confessional map of Switzerland, allowing each canton to determine its own religion and halting the further spread of the Reformation in the Confederacy for generations.

Zurich's reformation did not die at Kappel. Within weeks the city chose the 27 year old Heinrich Bullinger as Zwingli's successor at the Grossmünster, and over the next four decades Bullinger consolidated the reformer's work, corresponded with Protestant leaders across Europe, and composed the Second Helvetic Confession, which carried Zwinglian ideas into Reformed churches from Scotland to Hungary ^[5]. The alliance of Zurich's theology with Calvin's Geneva produced the broad Reformed tradition, the second great family of Protestantism alongside Lutheranism ^[3].

Any balanced Ulrich Zwingli biography must weigh his innovations against his severities. He pioneered continuous expository preaching in the vernacular, championed a church stripped to what scripture explicitly warranted, and sponsored one of the earliest complete Protestant Bibles ^[4]. At the same time he fused church and civic authority so tightly that dissenters like the Anabaptists faced exile and execution, and his willingness to advance the gospel through blockade and war ended in his own death in battle ^[2].

Modern Zurich remembers him with a bronze statue beside the Wasserkirche, sword and Bible in hand, erected in 1885, and the Swiss Reformed churches trace their institutional descent directly to his ministry ^[1]. Historians continue to study him as the most political of the first generation reformers, a figure who demonstrated that the Reformation could be carried not only by a prince or a university but by a city council persuaded, sermon by sermon, to remake its religious life ^[5].
