Contradiction with Hebrews 7:3
Melchizedek is described as having neither beginning of days nor end of life, contradicting Genesis 14:18 where he appears as a historical king with a specific role.
Hebrews 7:3: Without father, without mother, without descent, having neither beginning of days, nor end of life; but made like unto the Son of God; abideth a priest continually. [without descent: Gr. without pedigree]
Contradiction with Psalm 110:4
Describes Melchizedek's priesthood as eternal, contradicting the temporal event in Genesis 14:18 where he is a king and priest at a specific time.
Psalm 110:4: The LORD hath sworn, and will not repent, Thou [art] a priest for ever after the order of Melchizedek.
Contradiction with John 6:53-54
Jesus speaks of eating His flesh and drinking His blood to have eternal life, contradicting the sacrificial offering of bread and wine by Melchizedek in Genesis 14:18 as a symbol without explicit eternal life promise.
John 6:53-54: Then Jesus said unto them, Verily, verily, I say unto you, Except ye eat the flesh of the Son of man, and drink his blood, ye have no life in you.
Paradox #1
Genesis 14:18 mentions Melchizedek as both a king and a priest, which could be seen as a contradiction because, later in the Bible, the roles of king and priest are typically kept separate under the Mosaic Law, especially in the context of Israelite society. This separation is exemplified by the distinct lines of King David from the tribe of Judah and Aaron from the tribe of Levi, who held the priesthood. Melchizedek's dual role challenges this later-established separation.
Paradox #2
One potential contradiction in Genesis 14:18 is the mention of Melchizedek as both a king and a priest. In historical context, the combination of king and priest roles in one individual is rare and not well-documented in ancient Near Eastern societies, leading to debates about the historicity and origin of Melchizedek's character.
