[20]  Melchizedek was Cainan in the post flood system and Jared in the pre flood system

Melchizedek is a key character in the scriptures, but no man in recent times has known who he was. So, OK, put down your Agatha Christie novel, turn off your favourite detective series, put on your Sherlock Holmes hat, and lets do some detective work with the bible to find this elusive character. Paul describes Melchizedek as follows...

1 For this Melchizedek, king of Salem, priest of the Most High God, who met Abraham returning from the slaughter of the kings and blessed him.
2 and to whom Abraham apportioned a tenth from all things, is first of all, by translation, "King of Righteousness," and is then also king of Salem, that is, "King of Peace."
3 In being fatherless, motherless, without genealogy, having neither a beginning of days nor an end of life, but having been made like the Son of God, he remains a priest perpetually.
4 Behold, then, how great this man was to whom Abraham, the family head, gave a tenth out of the chief spoils.
5 True, the men from the sons of Levi who receive their priestly office have a commandment to collect tithes from the people according to the Law, that is, from their brothers, even if these have issued from the loins of Abraham.
6 But the man who did not trace his genealogy from them took tithes from Abraham and blessed him who had the promises (Hebrews 7).

God himself is both fatherless and motherless, being uncreated (whatever that means). All the rest of creation has both a father and a mother. But here Melchizedek is fatherless and motherless having no genealogy and no beginning of days nor end of life, this is the precise DNA of God. 

Lets us build up a detective's white board for Melchizedek, like chief inspector Cluseau would do.

1. Melchizedek was non adamic, being made like the son of God.
2. He was without genetic/physical parents. 
3. He had everlasting life. 
4. He was in some sense without genealogy.
5. He was not a son of Abraham.
6. He was a high priest, with a priesthood greater than the Levitical priesthood
7. Abraham paid tithes
(10% of everything) to him.

These are 7 distinguishing features of Melchizedek. Who else in the scriptures matches this profile? Well there is a chap with a very strange genealogy who lived at the time when Abraham paid tithes to Melchizedek, called Cainan.

Luke says that Cainan was a son of Arpachshad and that Shelah was a son of Cainan.

35 Son of Eber
Son of Shelah
36 Son of Cainan
Son of Arpachshad
Son of Shem
Son of Noah (Luke 3)

Whereas Moses describes Shelah as the son not of Cainan but of Arpachshad both in Genesis 10 and in Genesis 11. 

24 And Arpachshad became father to Shelah, and Shelah became father to Eber (Genesis 10).

12 And Arpachshad lived 35 years. Then he became father to Shelah. 
13 And after his fathering Shelah Arpachshad continued to live 403 years. Meanwhile he became father to sons and daughters.
14 And Shelah lived 30 years. Then he became father to Eber
15 And after his fathering Eber Shelah continued to live 403 years. Meanwhile he became father to sons and daughters (Genesis 11).

So now please dear reader, indulge the writer whilst he asks a load of transparently rhetorical questions. Was the God who created all of our languages in one instant at the tower of Babel (Genesis 11:7), unable to get two of his bible writers to write consistent accounts about Cainan? Is the one who stretched out the heavens by his own understanding, incapable of understanding the genealogy of one man? 

12 He is the Maker of the earth by his power, the One firmly establishing the productive land by his wisdom, and the One who by his understanding stretched out the heavens [Yes, an expanding universe, not known by mankind until Edward Hubble in 1929]. (Jeremiah 10 NWT)

Did the one whose abundance in dynamic energy created all the stars (Isaiah 40:26) run out of batteries when it came to inspiring both Luke and Moses?

Evidently not. So if we cannot reconcile these two accounts then it is our understanding and our power that is failing, not God's. So how do we reconcile these two accounts? Well the key line is to be found in Luke...

23 Furthermore, Jesus himself, when he commenced [his work], was about 30 years old, being the son, as the opinion was, of Joseph, [son] of Heli (Luke 3).

Luke is a genealogy that is not wholly physical. For Jesus was not a physical son of Joseph. Whereas Genesis 11, being an old testament genealogy, is entirely physical. So the ancestral path of Genesis from Arpachshad to Shelah is entirely physical, and Shelah was Arpachshad's genetic son, whereas the ancestral path of Luke from Arpachshad to Cainan to Shelah cannot have been entirely physical.

But nonetheless Cainan replaces Arpachshad who was Shelah's genetic father. How can this be? Well, Luke is telling us that Arpachshad was not Shelah's genetic father at the time Shelah had Eber, whereas Genesis is telling us that he was Shelah's genetic father at the time Arpachshad had Shelah. So between his birth and his fathering of Eber, Shelah must have changed fathers somehow. In other words he changed human bodies. We do know how he did this because being Christians, we believe in the resurrection of the dead. So Shelah died and was resurrected. Cainan is therefore the father of Shelah by resurrection. In other words Cainan resurrected Shelah.

In this way Lazarus also had two physical fathers, his genetic father and Jesus. Because his genetic father did not father the second body of Lazarus, Jesus mediated the creation of that body. It was actually a non-adamic body, because Lazarus, having died, was no longer under an adamic death sentence. No doubt Lazarusí second body looked exactly like the first, but his second father was the eternal father, Jesus Christ. You may ask then why did Lazarus die a second time? - See U9.

A resurrection is really the highest form of human priesthood. It was not possible for a son of post fall Adam, being under a death penalty himself, to resurrect anyone, during the Alienation Times (a priesthood malediction - see U128) before Jesus died and ransomed Adam both angelically and humanly,  releasing both him and his sons from that death penalty and ending the Alienation times on 33Sivan5, when God took the ransom he was given on 33Nisan16. Peter resurrected Dorcas and Paul resurrected Eutychus after Jesus died. 

40 But Peter put everybody outside and, bending his knees, he prayed, and, turning to the body, he said: Tabitha, rise!" She opened her eyes and, as she caught sight of Peter, she sat up (Acts 9).

9 Seated at the window, a certain young man named Eutychus fell into a deep sleep while Paul kept talking on, and, collapsing in sleep, he fell down from the third story and was picked up dead.
10 But Paul went downstairs, threw himself upon him and embraced him and said: Stop raising a clamour, for his soul is in him.
11 He now went upstairs and began the meal and took food, and after conversing for quite a while, until daybreak, he at length departed.
12 So they took the boy away alive and were comforted beyond measure (Acts 20).

All the resurrections of the old testament (including those by Elijah and Elisha) were in fact performed by non adamic humans. So Cainan was a non adamic priest. But Luke describes him as a son of Arpachshad. Well Melchizedek was fatherless and motherless in the post flood system, and the genealogy of Luke is not entirely genetic. So this is a spiritual fattherhood, a fatherhood by baptism. Arpachshad baptised Cainan into the PCC (the Peleg Church Covenant), just as John baptised Jesus into the 1EC (the 1st Elijah Covenant) inferior to the ICC (the Isaaic Church Covenant). So Cainan was Arpachshad's son through the PCC. In fact as we shall see in section I28, Melchizedek mediated the FRC and since he met Abraham in Genesis14, he mediated the 1AC (First Abrahamic Covenant) to Abraham. For more on this see the technical note below.

In fact Peter and Paul both had everlasting life when they performed their resurrections - see U506 on the research site. One cannot direct the Holy Spirit (which is the collection of all the holy spirits - see I11), without being oneself a holy spirit, i.e. having oneself been declared righteous in the spirit, i.e. having been given everlasting life - see U13. Also no son of Adam could resurrect anybody during the priesthood malediction of the Alienation Times from 2488Sivan BC to 33Sivan5 AD. So Cainan, who resurrected Shelah, was non adamic and had everlasting life. 

But if Melchizedek just beamed down to the post flood system, where did he come from?

Well he was made like the son of God. So he was a non adamic son to surrogate parents. These parents did not exists in the post flood system for which he had no traceable genealogy. So they existed in the preflood system.  There were 3 non adamic patriarchs in that system, Jared, who lived 962 years (2 too many for an adamic), Enoch, who was transferred so as not to see death and therefore was not under the adamic death sentence and therefore was non adamic, and Methuselah who lived 969 years (9 too many to be adamic). We saw that Michael possessed Enoch in I16. Methuselah was a non adamic but had a non adamic genealogy from Enoch who was his non adamic father. Whereas the father of Jared is listed as Mahalalel, who was adamic. So Mahalalel was the surrogate father of the adamically conceived Jared. But then God gene zapped him to be non adamic and that made his fatherless and motherless and without a human genealogy. So Jared was Melchizedek.

So Jared, died not judicially but sacrificially (being non adamic), and then beamed down as a non adamic human to be Cainan (who was Melchizedek), then Jehoiada, then Daniel, then Simeon. Furthermore each time he beamed down he presided over the entrance of the Angel Gabriel into another non adamic human. Understanding this, is the key to unlocking the identities of all 15 or more non adamic humans in the bible - see I21

Technical Note: How exactly was Arpachshad Cainan's father ?

The Septuagint (the first Greek translation of the Hebrew Old Testament, made by 70 Greek scholars in Alexandria in the 3rd century BC), helps us out here. 

And Arpachshad lived 135 years and begat Cainan. And Arpachshad lived after he begat Cainan 430 [400] years and begat sons and daughters and died.
And Cainan lived 130 years and begat Sala (Shelah) and Cainan lived after he begat Shelah 330 years and begat sons and daughters and died.
And Shelah lived 130 years and begat Heber (Eber). And Shelah lived after he begat Eber 330 years and begat sons and daughters and died (LXX Genesis 11).

These 'begat's are all second births, since we know from the BHS (the Hebrew old testament) that the first births were much earlier...

24 And Arpachshad became father to Shelah, and Shelah became father to Eber (Genesis 10).

12 And Arpachshad lived 35 years. Then he became father to Shelah. 
13 And after his fathering Shelah, Arpachshad continued to live 403 years. Meanwhile he became father to sons and daughters.
14 And Shelah lived 30 years. Then he became father to Eber
15 And after his fathering Eber, Shelah continued to live 403 years. Meanwhile he became father to sons and daughters (BHS Genesis 11).

But a second birth is being born again - see I12, which is a type of baptism. Arpachshad was born in 2369 BC. So he baptised Cainan into the PCC 135 years later in 2234 BC. Peleg was born in 2270BC. So he would have become the mediator of the PCC at 30 years old in 2340, 6 years before Cainan was baptised into it. This was necessary in order for Cainan to become the high priest of God's true people, the sons of the PCC, at that time. 

Cainan needed to be placed in the paternal Line to Jesus, a line of 77 people from Adam to Immanuel to Jesus, not 76. He could only join that line by baptism. His baptism put the line back together again. In fact Satan may have thought that by killing Shelah he would terminate the line to Jesus. This could have been fixed by another son of Arpachshad in theory but the bible does not describe him as having any more sons than Shelah. If he had no other sons, then to put the line back together again, God had to resurrect Shelah after baptising Cainan, his resurrection father, into the line. 

Melchizedek is the King of Eden2

Jared was the first non adamic human born after Adam sinned. So he is the firstborn non adamic human. So he is the firstborn edenic or kingdom human. So he is the head of all humans in the first Kingdom of God which was established on Eden2 - see U54. He is King of Salem1. Jerusalem is Salem2. 

2 and to whom Abraham apportioned a tenth from all things, is first of all, by translation, "King of Righteousness," and is then also king of Salem, that is, "King of Peace" (Hebrews 7).

And since it is written...

6 Just as he says also in another place: You are a priest forever according to the manner of Melchizedek. (Hebrews 5)

Melchizedek has everlasting life and will never lose it or his priesthood. Melchizedek is the second Adam. Jesus is the last Adam, the last son of Man.

1 For this Melchizedek, king of Salem, priest of the Most High God, who met Abraham returning from the slaughter of the kings and blessed him.
2 and to whom Abraham apportioned a tenth from all things, is first of all, by translation, "King of Righteousness," and is then also king of Salem, that is, "King of Peace."
3 In being fatherless, motherless, without [human] genealogy [being a non adamic son of God like Adam, the second Adam in fact], having neither a beginning of days [in the peri-flood system, having descended into it in adult form. He did have a beginning of days in the pre-flood system in Jared] nor an end of life [got everlasting life], but having been made [originally] like the Son of God [like Jesus. So he was a non adamic human, Jared, with surrogate adamic parents, Mr and Mrs Mahalalel], he remains a priest perpetually.
4 Behold, then, how great this man was to whom Abraham, the family head, gave a tenth out of the chief spoils.
5 True, the men from the sons of Levi who receive their priestly office have a commandment to collect tithes from the people according to the Law, that is, from their brothers, even if these have issued from the loins of Abraham.
6 But the man who did not trace his genealogy from them took tithes from Abraham and blessed him who had the promises (Hebrews 7).
