Hierarchy of the Catholic Church

What is the Hierarchy of the Catholic Church

The hierarchy of the Catholic Church consists of its bishops, priests, and deacons.[1][2] In the ecclesiological sense of the term, "hierarchy" strictly means the "holy ordering" of the Church, the Body of Christ, so to respect the diversity of gifts and ministries necessary for genuine unity (1 Cor 12).

What is Bishop?

The bishop or eparch of a see, even if he does not also hold a title such as Archbishop, Metropolitan, Major Archbishop, Patriarch or Pope, is the centre of unity for his diocese or eparchy, and, as a member of the College of Bishops, shares in responsibility for governance of the whole Church (cf. Catechism of the Catholic Church, 886). As each local particular Church is an embodiment of the whole Catholic Church, not just an administrative subdivision of something larger, the bishop who is its head is not a delegate of the Pope. Instead, he has of himself primary teaching, governance and sanctifying responsibility for the see for which he has been ordained bishop.

What is a Parish Priest? What does a Parish Priest do?

The parish priest is the proper pastor of the parish entrusted to him. He exercises the pastoral care of the community entrusted to him under the authority of the diocesan Bishop, whose ministry of Christ he is called to share, so that for this community he may carry out the offices of teaching, sanctifying and ruling with the cooperation of other priests or deacons and with the assistance of lay members of Christ's faithful, in accordance with the law
