At the head of secular clergy of the Roman Church was the Pope, (the Eastern Orthodox Church was headed by the Patriarch of Constantinople).
The cardinals were archbishops who were additionally empowered to elect a pope when one was needed.
The archbishops were lords over lesser bishops.
The bishops were lords over parish priests. In addition to the duties of the priests, they had the power to ordain priests and confirm believers.
The Priests were lower, they had the power to baptize, perform marriages and funerals, and say Mass.
Deacons were allowed to perform such sacraments as baptism, but not Mass.
