Clerical hierarchy refers to the structured organization of roles and responsibilities within religious institutions, particularly in Christianity. It typically includes various levels of authority, starting from the lowest rank, such as deacons, to higher positions like priests and bishops. Each level has specific duties and functions, contributing to the overall governance and spiritual leadership of the community. This hierarchy helps maintain order and ensures that religious practices and teachings are consistently upheld. It also provides a clear pathway for individuals seeking to advance in their religious careers, allowing for mentorship and guidance from those in higher positions, such as cardinals and the pope.
