“Holy Orders is the sacrament through which the mission entrusted by Christ to his apostles continues to be exercised in the Church until the end of time…It includes three degrees of order: episcopate, presbyterate, and diaconate” (CCC 1536). Deacons, priest and bishops are essential to the Catholic Church because we believe that they continue the work begun by the apostles.
Ordination is the rite at which the Sacrament of Holy Orders is bestowed. The bishop confers the Sacrament of Holy Orders by the laying on of hands which confers on a man the grace and spiritual power to celebrate the Church’s sacraments.
Who Receives Holy Orders?
The Second Vatican Council reminds us that the mission of ordained clergy, while unique, is interrelated to the mission of the lay faithful:
Though they differ from one another in essence and not only in degree, the common priesthood of the faithful and the ministerial or hierarchical priesthood are nonetheless interrelated: each of them in its own special way is a participation in the one priesthood of Christ. The ministerial priest, by the sacred power he enjoys, teaches and rules the priestly people; acting in the person of Christ, he makes present the eucharistic sacrifice, and offers it to God in the name of all the people. But the faithful, in virtue of their royal priesthood, join in the offering of the Eucharist. They likewise exercise that priesthood in receiving the sacraments, in prayer and thanksgiving, in the witness of a holy life, and by self-denial and active charity. (Lumen Gentium 10)
