I've put a lot of thought into that over many years, and I'm still not sure, but currently I'm thinking that one of the meanings is a prophet who teaches by acting out a story, like Ezekiel. In fact, Jesus could be referring to Ezekiel specifically, as a clue to what he is doing. Not bringing the same message, but teaching in the same way.
You have no idea how much the title 'Son of man' is important.At least i saw it like that.
I don't remember which Jewish Rabbi was , but looking into Jewish understanding i saw that God can incarnate.
Genesis 19:24 reads:
'Then Yahweh rained on Sodom and Gomorrah brumstone and fire from Yahweh out of Heaven'
And the Hebrew actually says here Yahweh twice.
So how can Yahweh be here and there is the question.
You can see also in Amos 4:11
'I have overthrown some of you, as Elohim overthrew Sodom and Gomorrah, and ye were as a firebrand plucked out of the burning: yet have ye not returned unto me, saith YHWH'.
The Hebrew word for 'God' in this verse is given the transliteration as ALEIM, which a form of ELOHIM , which, in turn, is a form of EL. It is used as a plural intensive, that is, the plural form is used as a singular in order to intensify the meaning, as in our English superior or superlative forms. The basic form is EL, which has the basic meaning of strength, might, power.
You might look into this:
Daniel 7:13
'In my vision at night I looked, and there before me was one like a son of man,coming with the clouds of heaven. He approached the Ancient of Days and was led into his presence.'
But the old testament tells us that only YHWH comes in the clouds of heaven.
So again we have two God figures in some sence.
The interesting thing is Daniel 7:14:
'He was given authority, glory and sovereign power; all nations and peoples of every language worshiped him. His dominion is an everlasting dominion that will not pass away, and his kingdom is one that will never be destroyed.'
Again , we have 'worship'.
As you may know YHWH is a jealous God according to the OT.
Worship is mentioned in the Bible 100+ times and is due to God alone.
So again we have conflict between two figures , YHWH - Son of Man.
So who is YHWH and who is Son of Man.
We know who is YHWH by Exodus 3:14
אֶהְיֶה אֲשֶׁר אֶהְיֶה
'I am that I am' or just 'I am' as it is said "tell them that 'I am' has sent you.
So , we have Jesus claiming both 'Son of Man' and YHWH.
The term, Son of man, is used by Jesus 80 times as a way to refer to himself.
-32 times in Matthew
-14 times in Mark
-26 times in Luke
-10 times in a qualitatively different way from the Synoptic Gospels in John
In all these texts Jesus is the speaker; no one ever addresses him as Son of man.
So where is the connection between Son of Man and YHWH?
John 8
"Jesus replied, 'If I glorify myself, my glory means nothing. My Father, whom you claim as your God, is the one who
glorifies me.Though you do not know him, I know him. If I said I did not, I would be a liar like you, but I do know him and obey his word.Your father Abraham rejoiced at the thought of seeing my day; he saw it and was glad.
'You are not yet fifty years old,' they said to him, 'and you have seen Abraham!'.
'Very truly I tell you,' Jesus answered,
'before Abraham was born, I am!' At this, they picked up stones to stone him, but Jesus hid himself, slipping away from the temple grounds."
And Mark 14 where the Sanhedrin adresses Jesus
"Then the high priest stood up before them and asked Jesus, 'Are you not going to answer? What is this testimony that these men are bringing against you?' But Jesus remained silent and gave no answer.
Again the high priest asked him, 'Are you the Messiah, the Son of the Blessed One?'
'
I am,' said Jesus. 'And you will see
the Son of Man sitting at the right hand of the Mighty One and coming on the clouds of heaven."
I clearly see that in the accounts of the Gospels Jesus claims to be God.Clearly , that's not even a matter of opinion.
I see that also in the second part of the NT.
