Paul explicitly notes the setting aside of the law and argues that if the first covenant were flawless, there would be no need for another. The prophet thus admonishes, as the Lord promises a new covenant with the house of Israel and Judah, distinct from the covenant established when He brought them out of Egypt; for, they did not adhere to that covenant, prompting Him to disregard them. He declares that He will place His laws within their minds and inscribe them on their hearts, promising to be their God, and they will be His people. No one will need to instruct their neighbor to know the Lord, for all will know Him, as He will be merciful to their transgressions, forgetting their sins and iniquities.
Further, by calling it "new," He highlights the obsolescence of the first covenant, which is indeed near to its end. Therefore, the law lacks the power for sanctification. Yet, justification in Christ and its accompanying service is far greater, as evidenced by God's voice through the prophets, who addressed those clinging to the inadequate commandments. "Wash yourselves; cleanse your hands," and "I desire mercy, not sacrifice."
We are redeemed in Christ, wherein we see and know the Father, able to trace countless proofs within the Scriptures where service under the law does not please God. To remain on topic, we turn to Abraham, who, upon learning of his nephew Lot's peril in Sodom, bravely assembled his household and allies to rescue him from captivity. Upon returning triumphantly, the king of Sodom encountered him in the Valley of Shaveh, which was the king's field.
Additionally, Melchisedec, the king of Salem and a priest of the Most High God, offered Abraham bread and wine, proclaiming him blessed by God, the creator of heaven and earth, for delivering his enemies into his hands. Remarkably, Abraham gave him a tenth of everything, illustrating the superiority of Melchisedec's priesthood over that of the law, as the lesser is blessed by the greater.
The narrative signifies that Melchisedec prefigures Christ, as all blessings in every instance flow from a higher source. Even the great priesthood represented by Aaron and Levi is subordinate to the divine priesthood of Christ. As Levi was yet in Abraham's lineage when Melchisedec blessed him, it symbolizes the ultimate righteousness granted by the ministry of Christ, of which Melchisedec is a foreshadowing.
It is evident that the greater blessing bestowed upon Abraham by Melchisedec represents an incomparable elevation. While some speculate that Melchisedec may have been simply a mere angelic figure or a glorious spirit, it is underscored that Melchisedec was indeed a king and a man, ruling in the city of Salem, where he symbolized both peace and truth.
As some scholars contend Melchisedec was not a man but rather a higher spiritual entity, they miss the core truth: no created being exists without genealogical reference or limits in time. The interpretation that Paul presents in relation to the priesthood of Melchisedec aimed to convey the idea that Jesus Christ became fully man to reveal God's righteousness and to open the way into a new covenant, ensuring peace with God.
In linking Melchisedec to Christ, Paul emphasizes the significance of his priesthood as a prototype of the one to come. The elements of bread and wine, offered by Melchisedec, foreshadow the sacramental blessings of the New Covenant, which we receive through Christ interceding on our behalf before the Father.
Melchisedec's blessing of Abraham, which acknowledged God's deliverance of enemies, mirrors the blessing Jesus offers us as our high priest, praying, “Holy Father, keep them in Your truth.” Through understanding the significance of these images, we recognize how they prefigure the work of Christ in establishing a new order of worship and relationship with God, fulfilling the promise of a deeper union with Him.
Thus, it becomes clear through scriptural references that Melchisedec is properly understood as a man, a king, and a priest, with Christ as His ultimate fulfillment, securing for us the everlasting blessings through His sacrifice and resurrection.
