Shalam and Greetings,
Christ is not Melchizedek, but instead came in the similitude of Melchizedek:
Heb. 7:15 And it is yet far more evident: for that after the similitude of Melchisedec there ariseth another priest,
The order of Melchizedek is the priesthood order which came before the Levitical priesthood.
Melchizedek according to Hebrew records is Shem. He was the priest who taught and raised Abraham in the word of the Most High. Shem’s priesthood came before that of Levi’s and Christ came in that same order.
Jasher, Go to Chapter 16:11-12. There you will find that Adonizedek/Melchizedek is not the messiah but is in fact Shem,
11. And Adonizedek king of Jerusalem, the same was Shem, went out with his men to meet Abram and his people, with bread and wine, and they remained together in the valley of Melech.
12. And Adonizedek blessed Abram, and Abram gave him a tenth from all that he had brought from the spoil of his enemies, for Adonizedek was a priest before God.
The same who taught Abraham. Yashaya is after the order of the high priest
Heb 6:20 Whither the forerunner is for us entered, even Yashaya, made an high priest for ever after the order of Melchisedec.
The Book of Josephus says this about Shem aka Melchizedek
2. So Abram, when he had saved the captive Sodomites, who had been taken by the Assyrians, and Lot also, his kinsman, returned home in peace. Now the king of Sodom met him at a certain place, which they called The King’s Dale, where Melchisedec, king of the city Salem, received him. That name signifies, the righteous king: and such he was, without dispute, insomuch that,
on this account, he was made the priest of God: however, they afterward called Salem Jerusalem. Now this Melchisedec supplied Abram’s army in an hospitable manner, and gave them provisions in abundance; and as they were feasting, he began to praise him, and to bless God for subduing his enemies under him. And when Abram gave him the tenth part of his prey,
he accepted of the gift: but the king of Sodom desired Abram to take the prey, but entreated that he might have those men restored to him whom Abram had saved from the Assyrians, because they belonged to him. But Abram would not do so; nor would make any other advantage of that prey than what his servants had eaten; but still insisted that he should afford a part to his friends that had assisted him in the battle. The first of them was called Eschol, and then Enner, and Mambre.
Book of Jubilees Chapter XIII.
25 for Abram, and for his seed, a tenth of the first-fruits to the Lord, and the Lord ordained it as an ordinance for ever that they should give it to the priests who served before Him, that they should possess it for ever.
26. And to this law there is no limit of days ; for He hath ordained it for the generations for ever that they should give to the Lord the tenth of everything, of the seed and of the wine and of the oU and of the cattle and of the sheep.
27. And He gave (it) unto His priests to eat and to drink with joy before Him. 28. And the king of Sodom came to
him and bowed himself before him, and said : ” Our Lord Abram, give unto us the souls which thou hast rescued, but
let the booty be thine.” 29. And Abram said unto him : ” I lift up my hands to the Most High God, that from a
thread to a shoe-latchet I shall not take aught that is thine, lest thou shouldst say I have made Abram rich ; save only what the young men have eaten, and the portion of the men who went with me—Aner, Eschol, and Mamre. These will take their portion.”
Even in the footnotes of the same book:
Patriarchae incircumcisi fuerunt, ut Melchisedech qui ipsi Abrahae jam circumciso . . . panem et vinum obtulit incircumcisus. To evade such attacks some Jewish writers declared that Melchizedek was born circumcised (Ber. rabba 43 ; for other references see Singer, p. 122 note) ;also that Melchizedek was identical with Shem (Targum Jon. and Jerus.
on Gen. xiv. 18 ; Nedar 32 & ; Ber. rabba 44 :
Book of Jashar [Diet, des Apocr. ii. 1125) ; see Beer, Leben Abrahams, 142 ; Singer, Das Buch der JubUden, 122
note for further references). These evasions were apparently unknown to Philo and Josephus. In connection with the fact that Melchizedek was called ” a priest of the most high God ”
(Gen. xiv. 18) we should remember that the Maccabeans called themselves by this title (see note on xxxii. 1). Now since our author (see lutrod. § 21) is an apologist of the Maccabean dynasty, it is not probable that he would omit all reference to Melchizedek who first bore.
so Shem is Abrams Great Great Great Grandfather if not more
