The Hierarchy of Orders and Jurisdiction
The Hierarchy of Orders and Jurisdiction.—The Orders of the clergy may be considered, not only in reference to power over the real Body of Christ (i.e., the Eucharist), but also in reference to power over the mystical Body of Christ (i.e., the Church). Those who have power over the members of the Church belong to the hierarchy, and this is understood in two senses:
(a) the hierarchy of Orders is composed of those who receive in Ordination a permanent superiority over others in reference to the worship of God and the sanctification of souls by the ministry of the Sacraments. From divine institution this hierarchy is composed of the three ranks of bishops, priests, and deacons; and from ecclesiastical institution of the lower clergy in Orders. Thus, the deacon is able to baptize and administer Communion as extraordinary minister; the priest is the ordinary minister of Baptism and the Eucharist, and only a priest can act as minister of Penance and Extreme Unction; the bishop is the minister, not only of the Sacraments mentioned, but also of Confirmation and Orders;
(b) the hierarchy of jurisdiction is composed of those members of the Church who receive in their accepted election or canonical commission a power over the faithful which can be lost or resigned, and which relates to the instruction and government of subjects in matters of faith and morals. From divine law this hierarchy is composed of the Supreme Pontificate and the subordinate Episcopate; from ecclesiastical law there are other ranks of authority, such as those of parish-priest, prelate, abbot, archbishop, primate, patriarch and cardinal.
