179. Why did Christ institute an ecclesiastical hierarchy?
Christ instituted an ecclesiastical hierarchy with the mission of feeding the people of God in his name and for his purpose gave it authority. The hierarchy is formed of sacred ministers,; bishops, priests, and deacons. Thanks to the sacrament of Orders, bishops and priests act in the exercise of their ministry in the name and person of Christ the Head. Deacons minister to the people of God in the diakonia (service) of word, liturgy, and charity.

180. How is the collegial dimension of Church ministry carried out?
After the example of the twelve Apostles who were chosen and sent out together by Christ, the unity of the Church's hierarchy is at the service of the communion of all the faithful. Every bishop exercises his ministry as a member of the episcopal college in communion with the Pope and shares with him in the care of the universal Church. Priests exercise their ministry in the presbyterate of the local Church in communion with their own bishop and under his direction.
