II. The Sacrament of Holy Orders in the Economy of Salvation

From The Catechism of the Catholic Church

1544
Everything that the priesthood of the Old Covenant prefigured finds its
fulfillment in Christ Jesus, the “one mediator between God and
men.”¹⁵ The Christian tradition considers Melchizedek,
“priest of God Most High,” as a prefiguration of the priesthood of
Christ, the unique “high priest after the order of Melchizedek”;¹⁶
“holy, blameless, unstained,”¹⁷ “by a single offering he
has perfected for all time those who are sanctified,”¹⁸ that is,
by the unique sacrifice of the cross.
