A fifteenth-century Bohemian sermon on the sole authority of Scripture and the path to salvation
What the Work Is
On Knowing the True Way to Salvation is a sermon delivered by Jan Hus, the Czech theologian and church reformer who became a central figure in the Bohemian Reformation of the early fifteenth century. Written and preached in Latin during a period of intense ecclesiastical controversy, the sermon represents Hus’s mature theological voice as he increasingly distanced himself from the institutional church’s claims to exclusive authority. The work survives as one of his most direct statements on how a Christian may be saved, and it reflects the reformer’s conviction that Scripture alone provides the reliable guide for salvation.
What the Book Is About
The sermon addresses what Hus regarded as the most fundamental question facing every Christian: how one can know the true way to salvation. For Hus, the answer lay in the Bible as the sole authority for Christian belief and practice. He condemned the sale of indulgences as a perversion of genuine repentance and insisted that no human institution, however venerable, could supersede the clear teaching of Scripture. The sermon thus functions as both a pastoral guide for ordinary believers and a polemical intervention in the theological disputes of his day, challenging the church’s claims to mediate salvation through its own institutional mechanisms.
Key Ideas and Themes
At the heart of Hus’s sermon lies the principle that Scripture constitutes the only trustworthy authority for every person seeking salvation. This conviction, which he shared with the English reformer John Wycliffe, placed the Bible above popes, councils, and ecclesiastical tradition. Hus did not merely assert this principle theoretically; he drew practical consequences from it that brought him into direct conflict with church authorities.
The sermon’s treatment of indulgences is particularly significant. Hus argued that the church’s practice of selling indulgences—remissions of temporal punishment for sin—had no biblical foundation and corrupted the true meaning of repentance. By attacking indulgences, Hus struck at a practice that was both theologically dubious and financially lucrative for the papacy, making his sermon not merely a devotional text but a direct challenge to the church’s institutional power.
Hus’s understanding of salvation was thoroughly grace-oriented. He maintained that human beings cannot earn their salvation through works or religious observances, but must rely on divine grace. This emphasis on grace over human merit anticipated themes that would become central to the Protestant Reformation a century later, though Hus himself never left the Catholic Church and continued to regard himself as a faithful son of the church even as he criticized its corruptions.
The sermon also reflects Hus’s conviction that the church as an institution was fallible and that its leaders could err. This belief in the fallibility of the church, even of the papacy itself, was a radical departure from the prevailing theology of his time, which tended to invest the institutional church with near-absolute authority. For Hus, the church’s authority was conditional on its fidelity to Scripture; when it departed from biblical teaching, it forfeited its claim to obedience.
Structure and Approach
The sermon follows the homiletic conventions of late medieval preaching, beginning with a scriptural text and developing its themes through exegesis and application. Hus’s method was to ground his arguments in biblical passages, which he interpreted with a directness and clarity designed to make the path to salvation intelligible to ordinary Christians. His approach was pastoral as much as theological: he sought not merely to expound doctrine but to guide his hearers toward a living faith that would issue in genuine repentance and holy living.
The sermon’s style reflects Hus’s training as a university master and his experience as a preacher in the Bethlehem Chapel in Prague, where he had preached in Czech to a largely lay congregation. Even in Latin, his preaching retains a directness and urgency that distinguishes it from the more speculative theology of his academic contemporaries. He was concerned with the practical question of how a Christian should live, not with abstract speculation.
Significance and Influence
On Knowing the True Way to Salvation occupies an important place in the history of pre-Reformation theology. Hus’s insistence on the sole authority of Scripture and his rejection of indulgences placed him among the forerunners of the Protestant Reformation, alongside figures such as Peter Waldo and John Wycliffe. Martin Luther himself later recognized Hus as a predecessor, and the Bohemian reformer’s teachings had a direct influence on the development of Hussitism, the movement that emerged in Bohemia after his execution at the Council of Constance in 1415.
The sermon’s significance extends beyond its immediate historical context. It represents a moment when the question of authority in the Christian church—whether it resides in Scripture or in the institutional hierarchy—was posed with unprecedented clarity. Hus’s answer, that Scripture alone is the sure guide to salvation, would echo through the following centuries, shaping the theology of the Reformation and the subsequent development of Protestant Christianity.
The work also illustrates the continuity between medieval reform movements and the Protestant Reformation. Hus did not invent his ideas in isolation; he drew on the legacy of earlier reformers, particularly Wycliffe, and his own teachings would in turn inspire later generations. The sermon thus stands as a link in a chain of reformist thought that stretched from the fourteenth century to the sixteenth and beyond, demonstrating that the questions Hus addressed were not merely local or temporary but touched on enduring issues in Christian theology.
For historians of Christianity, the sermon offers valuable insight into the intellectual and spiritual ferment of late medieval Bohemia, a region that became a crucible of reformist ideas. It shows how a theologian trained in the scholastic tradition could nonetheless challenge the institutional church on the basis of Scripture, and how pastoral concern for ordinary believers could fuel theological controversy. The sermon’s survival and continued study testify to its importance as a document of Christian reformist thought.
The source material places Hus within a broader historical framework of individuals and movements that historians have identified as forerunners to the Protestant Reformation. The article on Proto-Protestantism notes that before Martin Luther and John Calvin, the main forerunners of the Reformation were Peter Waldo, John Wycliffe, and Jan Hus. The source further states that Martin Luther himself saw it as important to have forerunners of his views and praised figures such as Girolamo Savonarola, Lorenzo Valla, and Wessel Gansfort as prefiguring some of his views.
The source material specifically identifies the Hussites as a 15th-century group in Bohemia that emerged after the execution of Jan Hus. It confirms that Hus was influenced by the writings of John Wycliffe, and it reiterates that Hus condemned indulgences and believed the scriptures to be the only authority for every man. This places the sermon’s core tenets—the condemnation of indulgences and the sole authority of Scripture—as defining characteristics of the movement that arose from his teachings.
Related Movements and Successionism
The source material also describes various factions and related movements that followed Hus. The Taborites, a faction of the Hussite movement, are noted for denying transubstantiation, the veneration of saints, prayers for the dead, indulgences, and confession to clergy, as well as renouncing oaths. The Utraquists, another group, insisted on communion under two kinds, apostolic poverty, “free preaching of the gospel,” and the use of Czech in scripture reading.
The source material also discusses the concept of successionism, which is the idea that proto-Protestants are evidence of a continuous hidden church of true believers. It notes that John Foxe was the first English Protestant author to defend Protestantism from charges of novelty by claiming the continuity of a proto-Protestant piety since apostolic times. The source also mentions that Baptist successionism postulates an unbroken lineage of churches with beliefs similar to those of current Baptists, and it includes the Hussites (partly) and Lollards (partly) in this lineage.
Criticism of the Proto-Protestant Category
The source material includes a section on criticism of the proto-Protestant concept. It states that the idea has been criticized as a diverse category whose only commonality is a perceived anti-Catholicism rather than any adherence to the five solae. The idea of successionism has been criticized as lacking historical evidence, linking unrelated groups, and as fabricated to serve a polemical need. The source specifically mentions that the inclusion of the Cathars or Albigenses as a Protestant forerunner has been a matter of controversy.
