"Holy Orders is the sacrament through which the mission entrusted by Christ to the apostles continues to be exercised in the Church until the end of time: thus it is the sacrament of apostolic ministry" (CCC, 383).
The entire Church is composed of a priestly people. Through Baptism, all the faithful participate in the priesthood of Christ, which is referred to as the 'common priesthood of the faithful.' Alongside this common priesthood, there exists another form of participation in Christ’s mission: the ministry conferred through the sacrament of Holy Orders. This ministry involves serving in the name and person of Christ the Head within the community.
