My personal suggestion:
Jesus Nazarene (or better, the Son of God possessing the mere son of man) was hungry in a spiritual sense (and not in a physical sense): his spiritual hunger of the coming Kingdom of God (the crucifixion of the son of man).
His spiritual hunger was reassured (and not ''frustrated'' as the usual vulgata wants it!) by the sight of the fig tree without fruit.
The disciples saw therefore a real fact: they didn't hallucinate the entire episode (as I had thought it was your opinion, wrongly) but the episode was real for both Jesus and the disciples (in the story).
Only, the mistake of the idiot Peter was the same of Matthew : To interpret the words of Jesus, at the light of the real fact of the drying of the fig :
...as words of condemnation of the fig and not instead as words of hope basing on a positive omen: the summer is near. THere is no more need of physical fruit because the spiritual fruit is coming!Mark “May no one ever eat fruit from you again.”
Therefore the miracle happens that the drying of the fig did satiate the spiritual hunger of Jesus: not only it did not bear fruit but even dried, confirming again and again the hope of Jesus that the end is already coming!
In short:
According to Peter and the idiot disciples | According to Son of God possessing a mere son of man | |
Jesus is hungry | the son of man is hungry for physical food | the Son of God has spiritual hunger of the Kingdom of God (=the crucifixion of the son of man). |
“May no one ever eat fruit from you again.” | words of condemnation of the fig (physical temple?) by the son of man | words of hope for the end of physical concerns and the arrival of a spiritual 'son of man': the new Israel, the pauline sect. |
drying of the fig | an omen that the son of man will destroy the physical temple (the fig) and the Romans. | a confirmation of the hope of the Son of God: there is no need of a fig (a physical temple), because there is no need of physical fruit. The spiritual fruit is already coming! The spiritual hunger is already satiated. |
Truly, I say to you, whoever says to this mountain, ‘Be taken up and thrown into the sea,’ | words empty of meaning | Read 1 Corinthians 13:2 |
And whenever you stand praying, forgive, if you have anything against anyone, so that your Father also who is in heaven may forgive you your trespasses.” | words empty of meaning | the fig is an insider! |
If the fig is an insider, then the blind of Betsaida, when he saw men as trees, was realizing that the trees know more than the idiot disciples.
