Jan Hus

Jan Hus (c. 1369–1415) was a Czech theologian, philosopher, and church reformer who served as rector of the University of Prague and preached at Bethlehem Chapel, where he delivered sermons in Czech to large popular audiences. Drawing heavily on John Wycliffe, he attacked ecclesiastical corruption, simony, and the temporal power of the papacy, arguing that the true church was the community of the predestined rather than the institutional hierarchy. His treatise De Ecclesia (1413) became the doctrinal core of his reform program and a foundational text for later Protestant ecclesiology. Summoned to the Council of Constance under an imperial safe-conduct, he was nonetheless tried for heresy, refused to recant, and was burned at the stake on 6 July 1415 — a martyrdom that ignited the Hussite Wars and made him a lasting symbol of conscience over coercion. His movement in Bohemia directly prefigured the Protestant Reformation and his influence on Luther was acknowledged by Luther himself.
