For this Melchizedek, king of Salem, priest of the Most High God, met Abraham returning from the slaughter of the kings and blessed him, and to him Abraham apportioned a tenth part of everything. He is first, by translation of his name, king of righteousness, and then he is also king of Salem, that is, king of peace. He is without father or mother or genealogy, having neither beginning of days nor end of life, but resembling the Son of God he continues a priest forever.
Hebrews 7: 1-3
The first priest in the Bible was not a Levite but the father of priests. The priest without genealogy the priest who existed before time existed. Could this high priest from the Old Testament come as the Lamb for sacrifice in the New Testament?
Melchizedek, King of Salem brought out bread and wine.
He brought out what would one day happen in the future as He made a covenant with Abraham son of man.
Melchizedek who I personally believe is the pre-incarnate Christ made a covenant with humanity. Melchizedek the pre-incarnate Christ makes a covenant with Abraham the father of nations. That one day Abraham’s seed which we are may be justified through grace. The bread depicting His body and the wine His blood. That one day Christ will suffer and die for humanity. This was a symbolic prophecy.
Therefore this covenant with Abraham was of utmost significance because this covenant with Abraham which is linked with the covenant of Christ with the Church. When the heavenly bridegroom comes for His bride the Church.
Now coming back to Melchizedek, who is this King and priest with no genealogy? I believe He is Christ our Lord. Why did this King and priest make a covenant with Abraham? So that the Father of nations depicting humanity would one day enter the holy of holies through the blood and body of Christ who died on the cross.
I believe that the meeting with Melchizedek and Abraham is the day time did a paradigm-shift. When Jesus walked back into time to meet this man called Abraham and the day Abraham walked into the future. The meeting of the two climaxed with a spiritual bang and Melchizedek blessed the father of many nations. When Melchizedek blessed Abraham He blessed us all because we are the children of Abraham.
