Melchizedek appears in only three verses of Genesis (14:18–20) — a mysterious king-priest of Salem who brings bread and wine to Abraham, receives his tithes, and blesses him — yet those three verses generate the longest typological argument in the New Testament. The author of Hebrews grounds Christ's priesthood not in Levitical genealogy but in a divine oath from Psalm 110:4: "Thou art a priest for ever after the order of Melchisedec." The argument turns on Melchizedek's apparent genealogical void: Scripture records no parentage, no birth, no death — not because he had none, but so that he stands as a figure of perpetual priesthood, pointing to the one whose priesthood requires no succession. Thomas Aquinas, compiling patristic commentary, drew the Eucharistic implication from the Genesis 14 offering itself: "Christian mysteries were before the Jewish" — Melchizedek's non-bloody oblation of bread and wine is "in all things like the Son of God," preceding the Levitical system by centuries and anticipating the Lord's Supper. Peter Lombard listed the Genesis 14 encounter explicitly as the third Old Testament type of the Eucharist. Hebrews 7 adds the argument from tithes: Abraham paid a tenth to Melchizedek, and since Levi was "in the loins of Abraham," Levi himself — through his ancestor — implicitly honored Melchizedek's higher priesthood. Matthew Henry follows Hebrews to its climax in Psalm 110: "The same Lord that said, Sit thou at my right hand, swore, and will not repent, Thou art a priest" — a sworn, unchangeable priesthood contrasting with every humanly appointed and hereditary line. Luther and Calvin both anchor the typology in this oath, and Andrew Murray distills the result: because Christ is Melchizedek, "King of Righteousness," he reigns as "King of Salem, King of Peace," fulfilling the prophetic hope that righteousness and peace would at last coincide.
What the primary sources show
"So also Christ glorified not himself to be made an high priest; but he that said unto him, Thou art my Son, to day have I begotten thee. As he saith also in another place, Thou art a priest for ever after the order of Melchisedec." — the divine oath from Psalm 110:4 applied to Christ: priesthood not by human appointment or genealogy, but by the Father's sworn word, establishing Melchizedek as the OT type for what the Levitical system could only shadow.
"Hence learn that the Christian mysteries were before the Jewish. Melchisedech offered bread and wine, being in all things like the Son of God, to Whom it is said, Thou art a Priest for ever after the order of Melchisedech; and of Whom it is here said, Jesus took bread." — Aquinas's catena on the Last Supper, placing Melchizedek's Genesis 14 offering as the Eucharistic type that antedates and supersedes the Levitical sacrificial order.
