Why is Melchizedek important in the context of Christ's priesthood?

Melchizedek serves as a crucial figure in understanding the priesthood of Christ as he embodies the qualities of an eternal priest and king, being both the King of Righteousness and the King of Peace (Hebrews 7:2). Unlike the Levitical priests, who belonged to a specific tribe and lineage, Melchizedek's priesthood is depicted as transcending these limitations, pointing to the unique nature of Christ's eternal priesthood. His appearance in Genesis reflects a divine appointment and suggests that God's perfect plan for redemption is realized in Christ, who surpasses all previous models of priesthood (Hebrews 7:3).
