Now, the Fall of the Temple c 70 CE is the event that caused the story of Jesus, the Son of God, "one like the son of Man" to be fabricated.
The Jesus story was not initially fabricated for a new religion but was an EXPLANATION [propaganda] for the destruction of the Temple of the Jewish God.
It was claimed that the Evil Jews KILLED the Son of God and therefore God destroyed Jerusalem and his own Temple.
It was AFTER people started to believed the propaganda that a New Religion was formed and the story was changed to include Salvation and Remission of Sins by Sacrifice when no such thing is in the early story of Jesus in gMark.
I am inclined to agree. Except that I think the "our holy city, temple, religion and way of life were destroyed because we did something wrong" meme was created by Jews. Josephus confirms this.
Contemporaneously with the date of the alleged composition of the gospels, the historian Josephus wrote that the calamity of AD 70 occurred because the then High Priest, Ananus was killed by fellow Jews.
"I should not be wrong in saying that the capture of the city began with the death of Ananus; and that the overthrow of the walls and the downfall of the Jewish state dated from the day on which the Jews beheld their high priest,
the captain of their salvation, butchered in the heart of Jerusalem." (Josephus, The Jewish Wars, 4.5.2 318)
The Book of Hebrews refers to Jesus as the High Priest.
Therefore, holy brothers and sisters, who share in the heavenly calling, fix your thoughts on Jesus, whom we acknowledge as our apostle and high priest. (Hebrews 3:1)
...and as "
the pioneer of their salvation"...
"In bringing many sons and daughters to glory, it was fitting that God, for whom and through whom everything exists, should make
the pioneer of their salvation perfect through what he suffered." (Hebrews 2:10)
So we have the Jewish state and the sacrificial system destroyed because the High Priest, Ananus, was butchered in the heart of the city. And where was the High Priest, Jesus, allegedly flayed and given the death sentence? In the heart of the city.
I say "allegedly" because while the death of the High Priest Ananus as well as the significance of that event is recorded by Josephus, the existence of the Christian sect and the death of its founder didn't rate so much as a footnote from the historian.
But I digress.
Christians say that sacrifices are no longer necessary because Jesus died for us once and for all. But isn't it much more likely that, in response to the ending of the sacrificial system caused by the destruction of the Temple, some 1st century Jews who wanted their religion to maintain some semblance of coherence came up with the idea of a man, a High Priest, who's death served as a final sacrifice rendering all future sacrifices unnecessary?
And isn't it just as likely that these new age Jews also used the death of this High Priest to explain why God had punished them "to the utmost" (1 Thess 2:14-16) by destroying the holy city and the Temple?
Josephus (Book 6, Chapter 5, Section 3 of The Wars of the Jews or History of the Destruction of Jerusalem)
has an account of another Jesus, Jesus ben Ananias who, like Jesus of Nazareth, prophesied the destruction of Jerusalem.
Both Jesus'...
1) were from the lower classes
2) preached a gloomy message about the fate of Jerusalem and it's people.
3) were arrested by the Jewish authorities
4) were then beaten by the Jewish authorities
5) refused to speak or represent themselves
6) after being interrogated and whipped by the Jewish authorities, were then brought to the Roman procurator
7) were then whipped by the Roman Procurator
8) did not cry out in pain during the whipping
9) were asked to identify themselves
10) were identified as madmen
11) were going to be released by the Roman procurator
12) last words were statements of despair about their own fates
13) were killed by the Romans
It would seem that significant plot elements of the gospel story were appropriated from Josephus. Or the story of Jesus ben Ananias was well known in the 1st century, became conflated with stories about the executed high priest and found their way into the gospels. Either way, the idea of the high priest's death resulting in the end of the Temple and the sacrificial system was not unique to Christianity.
All claims that Jesus died for Remission of Sins by Sacrifice and the resurrection was fabricated AFTER the Jesus story in gMark.
The author of the short gMark only knew a story that Jesus would be delivered up by the Jews, that he would be killed and resurrected.
Passages like Mark 4:12 tend to confirm your hypothesis. After all, if Jesus came to save people why did he couch his message in obscure language so as to insure that people would be damned?
10 When he was alone, the Twelve and the others around him asked him about the parables. 11 He told them, “The secret of the kingdom of God has been given to you. But to those on the outside everything is said in parables 12 so that,
“‘they may be ever seeing but never perceiving,
and ever hearing but never understanding;
otherwise they might turn and be forgiven!’” (Mark 4)
