What does Gregory the great extend authority of the papacy to raise?

Gregory the Great, who served as pope from 590 to 604, significantly extended the authority of the papacy by emphasizing the pope's role as a spiritual leader and a political authority. He asserted the pope's supremacy over the Church in the West and took an active role in addressing doctrinal disputes and secular affairs. Gregory also promoted the idea that the pope was a key mediator between God and humanity, which enhanced the papacy's influence in both religious and temporal matters. His efforts laid the groundwork for the centralization of ecclesiastical power in the papacy.
