An Erasmian Strategy: The Role of Jan Hus in Johannes Cochlaeus’ De immensa Dei misericordia erga Germanos (1538)

This article examines Johannes Cochlaeus’ De immensa Dei misericordia erga Germanos (1538) as a pivotal moment in the transformation of Catholic anti-Lutheran polemic. By contrasting Jan Hus’ moral sermons with Luther’s apocalyptic rhetoric, Cochlaeus strategically reconfigures the traditional Hus–Luther typology: Hus becomes a limited and partially reformist dissenter, while Luther appears as the true architect of schism. The study situates this rhetorical inversion within the broader political and theological context of the 1530s – marked by the prospect of a general council, the intensification of anti-conciliar propaganda, and the spread of Hussite ideas in Central Europe. Cochlaeus, driven by a concern to preserve the unity of Christendom and historical continuity, and to reclaim Hus from Protestant appropriation, constructs a rhetorical inversion in which Hus’ limited heterodoxy serves as a foil to Luther’s radical apostasy, employing the language of divine mercy to advocate the restoration of ecclesial unity through compassion rather than coercion. Particular attention is devoted to Cochlaeus’ Erasmian foundations: his emphasis on divine mercy, penitential renewal, and conciliar reconciliation. The article argues that De Immensa functioned as both a weapon against Lutheran radicalism and a programmatic attempt to integrate Erasmian humanism into pre-Tridentine Catholic strategy.
