Ecclesiastical hierarchy refers to the structured organization of authority within a religious institution, particularly in Christianity. It typically includes various levels of leadership, such as bishops, priests, and deacons, each with specific roles and responsibilities. This system helps maintain order and governance within the church. In many denominations, the hierarchy is often represented as a pyramid, with the Pope or Patriarch at the top, followed by higher-ranking clergy, and then local leaders. This structure facilitates decision-making, the administration of sacraments, and the overall spiritual guidance of the congregation.
