Stanislaus Hosius

The chapter presents Stanislaus Hosius as one of the leading Catholic theologians of the Reformation era and a major representative of Polish Counter-Reformation apologetics. It examines his biography and ecclesiastical activity as well as his principal polemical writings, in which he formulated a comprehensive defence of the Catholic understanding of Revelation and the Church. Central to his thought is the inseparable relationship between Sacred Scripture, Apostolic Tradition, and the teaching authority of the Church. His ecclesiology focuses on the four classical marks of the Church as well as its historical continuity and unity. The chapter also shows that, despite the polemical language characteristic of the period, Hosius’ work can be interpreted as an attempt to preserve Christian unity grounded in doctrinal truth.
