4. The Doctrine of Papal Supremacy
The Doctrine of Papal Supremacy, central to Roman Catholic theology, asserts that the Pope holds supreme authority over the entire Church. This principle has profoundly influenced Western Europe’s politics and society, particularly during the medieval period. It played a pivotal role in events such as the Crusades, the formation of nation-states, and conflicts with secular monarchs, shaping church-state relations that continue to evolve today. For a comprehensive understanding, refer to the Britannica entry on Papacy.
