Marcin Kromer

The chapter reconstructs the apologetic thought of Marcin Kromer, whose theological contribution is less widely recognised than his work as a historian, diplomat, and churchman. Particular attention is given to his Apologetyka, in which Kromer uses the literary form of dialogue to confront Catholic and Protestant positions. His method combines biblical exegesis, patristic testimony, conciliar teaching, historical evidence, and rational argumentation. The central area of his apologetics is ecclesiology, especially the defence of the primacy of the Bishop of Rome and the four marks of the true Church. The chapter presents Kromer as the author of a coherent programme for defending Catholic identity in the context of Reformation controversies.
