Melchizedek is mentioned in only three books of the Bible - Genesis, Psalms, and Hebrews. Here is what those writings tell us about Melchizedek:
Melchizedek lived on earth during the time of Abraham.
Melchizedek was the king of Salem, which is biblical Jerusalem.
Melchizedek has no earthly family record.
Melchizedek was a divine priest of God, not a human priest like Aaron.
Melchizedek means “king/ruler of righteousness.”
Priestly order of Melchizedek is everlasting.
Christ is our divine priest from the order of Melchizedek.
There are two priestly orders mentioned in the Bible - priestly order of Melchizedek and the priestly order of Aaron. Both came from God. The priestly order of Melchizedek is a spiritual/heavenly order that is holy and complete. The priestly order of Aaron is an earthly/physical order that is incomplete and serves as a shadow of the prefect priestly order of Melchizedek.
Christ came in the order of both. As the Messiah, Christ is eternal, he is not part of creation, he is the Creator. When Christ went to the cross it wasn’t earthly blood being shed, it was divine blood that was shed. Christ sacrifice wasn’t an earthly human sacrifice, that would have been an incomplete sacrifice not able to cleanse and save. It was a Divine sacrifice. When Christ put himself on the cross all of creation witnessed a spiritual communication out of this world that is holy and complete, fully capable of cleansing our conscience and making us righteous, restoring unto us our created identity. It was also spiritual communication to our enemy that he is defeated. Christ also fulfilled the priestly order of Aaron as he was made in our likeness, the personhood of Jesus.
Christ being the fulfillment of both priestly orders makes the old priestly order of Aaron obsolete, and established a new covenant where there is only one high Priest and he is Christ. Through Christ all are made righteous with God. This is what Christ meant when he said in John 14:6 — “I am the way, the truth, and the life. No one comes to the Father except through me.”
