On the Church
Jan Hus wrote this systematic treatise on the nature of the church in 1413 while serving as rector of the University of Prague, amid growing tensions between Bohemian reformers and the papal hierarchy. The work emerged from his lectures defending the theological positions that would soon bring him before the Council of Constance, where he would be condemned and executed despite promises of safe conduct.
Hus argues that the true church consists not of the institutional hierarchy but of the predestined elect, those chosen by God for salvation. Drawing heavily on John Wycliffe's ecclesiology while developing his own theological framework, he distinguishes between the visible church of mixed membership and the invisible church of the truly faithful. The treatise systematically dismantles claims of papal supremacy, arguing that Christ alone is the head of the church and that papal authority depends entirely on the pope's conformity to Christ's will and teaching. Hus contends that church officials, including the pope, can err and fall into sin, making obedience to ecclesiastical authority conditional on that authority's faithfulness to Scripture. He develops a theology of church membership based on divine election rather than sacramental participation, fundamentally challenging medieval Catholic ecclesiology.
The work became a cornerstone text for Protestant reformers, particularly in its insistence that Scripture trumps church tradition and that institutional authority must be subject to biblical critique. Its influence extended through the Hussite movement into the broader Reformation, shaping Lutheran and Reformed thinking about church government and authority. Who should read this: students of ecclesiology and Reformation history who want to understand the theological foundations that challenged medieval Christendom, and those interested in the development of Protestant church polity. This is not devotional reading but requires familiarity with medieval theological categories and Latin scholastic method.
