# Priesthood of Christ ## Catechism of the Catholic Church The unique high priest, according to the order of Melchizedek. Christ fulfilled everything that the priesthood of the Old Covenant prefigured. (cf. _Heb_5:10, 6:20). He offered himself once and for all (_Heb_10:14) in a perfect sacrifice upon the cross. His priesthood is made present in a special way in the Church through the ministerial priesthood, conferred through the Sacrament of [[holy-orders|Holy Orders]] ([[2.2.3.6.p4t#^ccc-1539|1539]], [[2.2.3.6.p4t#^ccc-1544|1544]], [[2.2.3.6.p4t#^ccc-1547|1547]], [[2.2.3.6.p4u#^ccc-1554|1554]]).
