Melchizedek's Role In The Old Mosaic Law

Though Melchizedek is a mysterious figure in the Old Testament, his role is made clear by the New. His unique role as a priest-king made him a type of Christ, a representation of what God intended to do in the latter days. His superior position over Abram makes him superior to any of Abram’s descendants. His duration as a priest is timeless, because his priesthood never ends. So, ultimately, his superior priesthood implies the inferiority of the Levitical priesthood, which necessitates a transition from the old Mosaic law to the new Christian law. And all these points came from merely two texts. The author of Hebrews skillfully arranged both and thoroughly exegeted them, using midrash to draw out the myriad of implications found in both. The
result of this detailed exposition is the furtherance of the author’s main point about Jesus’ superiority and proof of His current high priesthood in heaven. Both thoughts are anchors for the faith of all Christians, for not only are they part of a superior system, they have a superior high priest who provides direct access to the God of creation (Heb. 4:14-16; 6:19-20).
