What is the Church Hierarchy? How was the Catholic Church governed?

Church hierarchy is the location of ranks (spiritual dignities) in the church, which are in a certain relationship to each other. If we talk about the Catholic Church, then the Pope is above all, followed by archbishops and cardinals, followed by bishops, then priests and deacons. The Pope has indisputable authority, and the church is governed by a council of archbishops and cardinals. Bishops govern the territories entrusted to them. The priests are in charge of their parishes, and the deacons are the lowest rank in the hierarchy.
