Maciej Sieniatycki

The chapter presents Maciej Sieniatycki as a representative figure of Polish pre-conciliar apologetics and fundamental theology. His system followed the classical structure of demonstratio religiosa, demonstratio christiana, and demonstratio catholica, moving from the rational justification of religion to establishing the truth of Christianity and the Catholic Church. Sieniatycki’s reflection was deeply rooted in neo-scholasticism and the anti-Modernist context. Revelation was understood primarily in doctrinal terms, while the Church was presented as a visible institution entrusted with the authoritative transmission of revealed truth. The chapter highlights both the systematic strength of his project and the limitations characteristic of pre-conciliar Catholic theology.
