Priestly Orders refer to the different levels of ordained ministry within certain religious traditions, particularly in Christianity. These orders typically include the diaconate, priesthood, and episcopate. Each order has specific roles and responsibilities, with deacons assisting priests, priests serving congregations, and bishops overseeing multiple congregations and clergy. In the Catholic Church, for example, the sacrament of Holy Orders is conferred through a ritual that includes the laying on of hands. This sacrament signifies the recipient's commitment to serve the church and its members, following the example of Jesus Christ and the apostles.
