All "we" know is that you have a personal belief that the story was made up (for no apparent reason); you base your belief on the profound misconception that the story was set during a time of mass slaughter which actually did not start until forty years later.
What you are telling me is that you have never read Josephus; because, He declares loud and clear that the Romans crucified thousands of Jews during their occupation of Israel much before the destruction of the Temple in 70 ACE. Therefore, the mas slaughter of Jews was mostly done during the regime of Pilate in Judea.
Josephus tells of a Roman soldier guarding the outer periphery of the Temple grounds during Passover, who started a major riot by dropping his pants and mooning the crowd. I am sure this was not "policy" but I don't therefore doubt that it happened.
Right, it was not a Roman policy to behave thus, as it was not to spear pierce crucifieds to check if they were dead or not.
That is precisely what Paul DENIED in 1st Corinthians, that the risen Jesus was the kind of "flesh" body who eats-and-excretes. It was the DISCIPLES IN JERUSALEM who taught that the risen Jesus ate and drank (in later times, it was especially the Ebionites, the Jewish Christians who followed James the Righteous and detested Paul, who emphasized that the risen Jesus ate).
The disciples of Jesus thought nothing of the sort. It was Luke, a Hellenistic former disciple of Paul's, who said that Jesus appeared to his disciples for 40 days after his passion with infallible proofs that he was not a spirit but a living man, eating and drinking just as he used to do before.(Acts 1:3; Luke 24:39-43)
Both Jews and Christians produced pseudepigraphic books (falsely attributed to noted figures from the past) by the bushel load. I am astounded that you take for granted the genuineness of dubious texts (nobody had ever heard of "epistles to Timothy" until Paul had been dead 100 years, and they aren't in Paul's style or native dialect), while casually dismissing texts which tell their stories straightforwardly with every appearance of honesty.
I have no problem with that. IMO, most of the Tanach was written rather by Ezra than by the Jews whose names entitle them. Besides, it doesn't matter to me; as long as Jews wrote the Jewish Scriptures and not Hellenistic Gentiles.
