The biblical origins of the Mass and the New Testament priesthood are rooted in the Old Testament. Both the Old and New Testaments provide clear evidence that the Mass is a true sacrifice, offered by a priest, and the Victim is the Body and Blood, soul and divinity of Jesus Christ.
God stated three times that the Passover sacrifice would be an ordinance for ever, not for a temporary period, such as until the Messiah came. This sacrifice, and other Old Covenant sacrifices, find their culmination in Christs sacrifice on Calvary (Ex. 12:14, 17, 24; cf. Lk. 22:7-20). Christs sacrifice at the Last Supper was a sacrifice of His Body and Blood, soul and divinity (cf. Catechism, nos. 1362-67, 1373-77). Much as the sacrifice offered at the Last Supper fulfilled the Old Covenant sacrifices, the priesthood of Christthe priesthood of Melchizedekreplaced the Levitical priesthood of the Old Testament. This New Testament priesthood, handed on to the apostles and their successors, allows Christs sacrifice on Calvary to fulfill the perpetual ordinance of a sacrifice through the celebration of the Mass (cf. Heb. 6:19-7:28).
