G,
I think you are making far more of these two things than can really be warranted.
Point #1 (that people called Capernaum Jesus' "hometown") is just
an element in a in a literary source.
Point #2 (that the Gnostic Heracleon thought that Capernaum was "code" for the heavens of the Demiurge (a creator-god unaware of the higher god) is a later
interpretation of point #1. Heracleon, I am sure, saw many passages in the NT, Gospels and Pauline letters, suitable for
interpretation by means of allegory. This is a second order interpretation, as the proto-orthodox had themselves used allegory to
re-interpret passages in the Judean scriptures (Hebrew for the earliest royal messianists, and the Greek Lxx translation of same for the later "Christians" as we have come to know them) to produce point #1, among the many others folks like Heracleon saw as indications of the redeemer myth.
Point #3 is not correct. Points #1 & #2 can not be "coincidental" in themselves, but only in relation to one another, if that is how one wants to
interpret these two points. Same goes for your
interpretation that they are not coincidental. You have become Heracleon in the way you are thinking.
I prefer to attempt to understand the rationalization process by which interpretation takes place. If Leon Festinger's theory of 'cognitive dissonance" is correct, folks either try to reduce the dissonance they perceive by means of 1) reduction of the importance of the elements that produce the dissonance (circling the wagons to create a defensive position or "bubble," or attacking the elements to do away with them), or 2) synthesize them into their interpretive framework for understanding how the world works.
The latter is clearly what early Christians ended up doing with passages considered part of sacred literature (predicting a royal end-times leader who would usher in a millennial age of Judean dominance and prosperity), which came to clash with the real-world events that overtook them (the Judean war, the crushing defeat of the rebels and the subsequent loss of confidence that a Judean state could be imposed), producing a "spiritual kingdom" to be imposed by God, but not through war and military might, to be led by an already resurrected Jesus waiting in heaven at God's side to come back to take ceremonial command. Of course, he (as Jesus) was also believed to have instituted a new spiritual means of "sin removal" by his vicarious sacrifice, replacing the need for bloody temple sacrifices on Yom Kippur (the annual Day of Atonement practiced by the Judeans until their temple was destroyed).
Heracleon also did this, but created a new interpretation that something more was going on, that the national God worshipped by Jews and the creator God worshipped by Christians, was actually a secondary god and not the supreme one. In fact, the created world was a mistake and a poor copy of divine models at that, and that the true Supreme God was moved to take corrective action, sending Christ (an anointed - or officially sanctioned - representative) from the Supreme God's realm of existence to redeem the souls imprisoned in the material world who were capable of being reunited with the realm of the Supreme God. So, Jesus was much more than simply a redeemer sanctioned by the creator god. Now what events overcame Heracleon's circles to produce this new synthesis probably have to do with Egyptian politics, history and philosophy of which I am not fully familiar.
Why should we treat the third order interpretations of Heracleon as somehow implied by the earlier authors of second order interpretations in the NT books? Are you suggesting that the NT was in fact a production of Heracleon's time (that is, later than Christian tradition places them)?
Successive synthetic rationalizations by different parties over time seems to be more like the real world than books composed in the 2nd century CE that were artificially set in the 1st century, before the Judean rebellion, which suddenly becomes a "hit" with everybody because it was imposed from above (Gnostic
illuminati, Constantine, etc.)?
Seems conspiratorial, not rational.
Gotta go measure appliances (our refrigerator died and the stove is already a piece of junk) for replacement. At least $1,500 going down the drain!
