Holy Orders is the sacrament through which the mision entrusted by Christ to his apostles continues to be exercised in the Church until the end of time: thus it is the sacrament of apostolic ministry. From the moment of Jesus' conception in the womb of Mary until his Resurrection, he was filled with the Holy Spirit. In biblical language, he was anointed by the Holy Spirit and thus established by God the Father as our high priest. As Risen Lord, he remains our high priest. . . . While all the baptized share in Christ's priesthood, the ministerial priesthood shares this through the Sacrament of Holy Orders in a special way.
