The sacrament of Holy Orders is composed of three degrees which are irreplaceable for the organic structure of the Church: the episcopate, the presbyterate and the diaconate.
The anointing of the Spirit seals the priest with an indelible, spiritual character that configures him to Christ the priest and enables him to act in the name of Christ the Head. As a co-worker of the order of bishops he is consecrated to preach the Gospel, to celebrate divine worship, especially the Eucharist from which his ministry draws its strength, and to be a shepherd of the faithful.
