In the context of the biblical tithing system, a significant change is noted in the administration of tithes under the New Covenant. The priesthood has been conferred on Christ, now our High Priest according to the order of Melchizedek. Since the tithing law predates the Levitical priesthood and remains in force, tithes are now to be given to Jesus Christ, our High Priest, for use by the church. This adjustment in the law applies specifically to the ceremonial aspects related to the Tabernacle, Temple, and priesthood, ensuring that the principle of tithing continues under His authority.

In the discussion of priesthood, a distinction arises between the Aaronic priesthood and the priesthood after the order of Melchizedek. While it remains unclear whether the holy priesthood and royal priesthood mentioned are one and the same or represent different groups, it is evident that the establishment of the order of Melchizedek brought a change to the Aaronic priesthood. Our High Priest, Melchizedek, who is Jesus Christ, has torn away the veil, opening the way to the Tabernacle and granting us access to the Holy of Holies at any time. Only those chosen by God the Father can come to Him on the authority of Jesus Christ. As our King and High Priest, He is worthy of our lives, our praise, and our every breath. We must strive every minute of every day to uphold the name of our High Priest, who provides us unlimited access to the Most High, His Father and ours.

Psalm 110 provides the central biblical foundation for understanding the Order of Melchizedek as it applies to Jesus Christ. This psalm, composed of two divine oracles each followed by a glimpse of fulfillment, presents Christ first as King (verses 1-3) and then, in a new oracle beginning at verse 4, as eternal Priest: "The Lord has sworn and will not relent, 'You are a priest forever according to the order of Melchizedek.'" This shift in verse 4 moves the psalm's focus away from Messiah as a powerful ruler who conquers His enemies and toward Messiah as Priest, establishing that the Father Himself swears the highest and most irrevocable of oaths that His Son will hold this priestly office forever. The significance of this verse lies in answering a critical theological question: how can Jesus Christ qualify as High Priest when He is not a Levite and does not descend from Aaron? The order of Melchizedek resolves this problem because it represents a priesthood that exists prior to and supersedes the Levitical priesthood. The author of Hebrews expands on this single verse extensively across six chapters, from Hebrews 5 through Hebrews 10, demonstrating precisely how Christ qualifies for this office. The proof rests on the account of Abraham paying tithes to Melchizedek—since Levi was still in the loins of Abraham at that time, and since the lesser always pays tithes to the greater, this establishes that the order of Melchizedek holds a higher rank than the Levitical priesthood itself. Melchizedek's name itself carries theological weight: it means King of Righteousness, and since he ruled from Salem, he is also King of Peace—titles that both fit Jesus Christ perfectly. This reveals that unlike human systems requiring separate men to fill the offices of king and priest, Christ alone fulfills both offices simultaneously and perfectly. He is not merely King and not merely Priest, but King-Priest, the Anointed One who combines governmental authority with priestly mediation in a single divine Person. This truth connects directly to the psalm's concluding verses (5-7), which depict this same Priest-King returning in wrath to execute judgment among the nations, filling the earth with the dead bodies of His enemies, before being satisfied with complete victory—refreshing Himself and lifting up His head in triumph. The Priest-King thus conquers the world, establishing His Kingdom so that He may rule both as King and Priest, bringing peace and prosperity to creation. This vindicates the entire prophetic structure of the psalm: the same divine Person addressed as Adon in verse 1, who ascends to sit at the Father's right hand, is revealed in verse 4 as the eternal High Priest of the Melchizedek order, and finally in verses 5-7 as the victorious Judge and Ruler. The order of Melchizedek therefore stands as the divine, God-established priesthood, filled by God Himself through the Son, in contrast to the Levitical priesthood, which God ordained but staffed by mere human beings.
