In this blog post, we will examine the life and ideas of Jan Hus, a medieval Czech reformer, as well as the historical significance of his legacy.
Before Jan Hus, Bohemia experienced a brief period of revival during the reign of Charles IV, but subsequently fell into decline with the establishment of the Kingdom of Bohemia. The primary causes of this decline were the Black Death and the corruption of the medieval Church. The Black Death pushed people’s anxiety to its peak, and many believed that failing to properly follow the teachings of the Bible had provoked God’s wrath. It was against this historical backdrop that Jan Hus emerged to lead the Reformation.
The medieval European church had become deeply involved in secular politics and had become so corrupt that it had lost its original mission as a shepherd and strayed far from the apostolic example. The Pope raised funds to wage the Crusades and sold indulgences for this purpose. In addition to simony, the Church exercised taxing authority over its own lands, collecting various taxes and fees. It even operated taverns, inns, and gambling houses near churches, focusing on the accumulation of wealth.
Jan Hus was born in 1369 in the small town of Husinec. He enrolled at Charles University, earning a Bachelor of Arts degree in 1393 and a Master’s degree in 1396, and began teaching as a professor in 1398. In 1401, he became Dean of the Faculty of Philosophy, and in 1402, he was appointed Rector of the University; in 1403, he was appointed parish priest.
While serving as rector, he was influenced by the ideas of the English thinker John Wycliffe. Wycliffe argued that since the Church was unable to relinquish its secular power on its own, the state must intervene. Hus opposed the sale of indulgences and criticized Catholic priests, raising issues not only in theory but also in practice. These activities earned him widespread support from the Bohemian court, the nobility, and various social classes. Historians regard Wycliffe and Hus as figures who illuminated the “eve” of the Reformation. In particular, since Hus’s name means “goose” in Czech, he is sometimes described as “the goose that honked loudly on the eve of the revolution.”
The year after he became a priest, Hus began preaching at the Bethlehem Chapel. He condemned the Crusades as acts of massacring the innocent and criticized the sale of indulgences as blasphemy. As a result, pressure from the Church intensified: his sermons were banned, the chapel was destroyed, and measures were taken in Prague to suspend the sacraments. Hus left Prague and continued his literary work in southern cities, carrying on the Bohemian Reformation.
His reforms contained the following five key tenets.
First, he argued that the church should be a “place where virtue is realized” and that priests must be held to high moral standards. The disorderly lives of priests at the time were a serious problem.
Second, he argued that sermons and Bible readings should be conducted in the vernacular, and that all Christians should receive the full Eucharist. This undermined the clergy-centered hierarchy and became a symbol of the rejection of social privileges.
Third, he opposed the sale of indulgences, arguing that the forgiveness of sins comes solely through God’s grace, not through the Pope’s declaration or human merit.
Fourth, he opposed papal decrees that contradicted the Bible, emphasizing that the Bible is the supreme authority, surpassing even church leaders and councils.
Fifth, he believed that the pope was not the head of the church, and that the church should be an organic community with Christ as its head, rather than a clergy-centered institution.
These arguments led to the Protestant Reformation across Europe. In particular, innovations in language and space took place. Worship services were conducted in the vernacular rather than Latin, and in the Bethlehem Chapel—which differed from traditional cathedral structures—all believers could stand equally before the Word. While preaching at Bethlehem Chapel at Charles University, Hus gained such popular influence that he was called the “Teacher of the People,” and he continued to publish collections of sermons and write hymns. The Czech Reformation began at the university, and Charles University fully supported Hus. This was, in essence, a reform movement led by critical Christian intellectuals.
Hus strongly criticized the clerical authoritarianism advocated by the Church. In his seminal work, he stated, “The devil, the worst of sophists, tempts the priests,” likening priests who abused religious power to the devil’s minions. This ecclesiology demonstrates that he did not cease his criticism even after being exiled from Prague.
At the Council of Constance, held from 1414 to 1418, Holy Roman Emperor Sigismund summoned Hus to end the schism in the papacy. Although the emperor promised to guarantee his safety, Hus was arrested less than a month after arriving in Constance. He was denied the opportunity to defend himself at his trial and was ultimately burned at the stake in 1415. As he was being burned at the stake, Hus left behind the words, “Today they burn a ‘goose,’ but in a hundred years a ‘swan’ will appear and cry out louder than I.” This is interpreted as a prophecy of the future appearance of the Reformer Martin Luther and holds symbolic significance.
Even after Hus’s death, his reform movement did not cease. Czech nobles rebelled against the decisions of the Council of Constance, declaring, “We will obey the Pope only to the extent that it does not contradict God’s will.” In response, the Pope continued his crackdown, including the closure of Prague University and a ban on priestly ordinations. As the conflict intensified, the First Throwing of the Windows incident occurred. Ultimately, following the death of the King of Bohemia, the conflict escalated into a direct clash between the Hussite nobles and the papal authority, leading to the outbreak of the Hussite Wars.
The early Hussite Wars were led by Jan Žižka, known as the “One-Eyed General.” Using the city of Tabor as his base, he won several battles against the imperial army. Although there were five imperial offensives between 1420 and 1431, the emperor was ultimately unable to subdue the Hussites and began seeking a compromise. However, internal conflict within the Hussite movement intensified as factions split into moderates and hardliners. Eventually, the moderates prevailed over the hardliners, leading to a compromise with the emperor. The emperor recognized the practice of double communion and the freedom to preach the Gospel, while the Hussites acknowledged the emperor’s right to the Bohemian throne.
The “swan” prophesied by Hus was none other than Martin Luther. Luther identified himself as a Hussite and carried on Hus’s ideas. At the Diet of Worms, Luther criticized the church that had condemned Hus and emphasized the necessity of reform. Huss not only exerted an external influence on Luther but also sparked a theological awakening regarding the need for the church to become a Christ-centered, evangelical community. However, there is a difference in that while Luther’s Reformation was more theological, theoretical, and legal in nature, Huss led a practical, pastoral, and dynamic reform.
October 31, 2017, marked the 500th anniversary of Luther’s publication of the 95 Theses, and July 6, 2015, marked the 600th anniversary of Jan Hus’s burning at the stake. While many people commemorate Luther’s Reformation, the Reformation actually began in Bohemia 100 years earlier. Luther’s Reformation was an extension and further development of Hus’s, and Hus’s Reformation was by no means merely a precursor. Therefore, we must commemorate and remember not only Luther’s Reformation but also Jan Hus’s Reformation—which can be called the “First Reformation”—as a complete and distinct reform in its own right.
