The early Jewish and Christian interpretation of Daniel’s Son of Man
From the very beginning the Son of Man of Daniel was identified as the Messiah. In fact this has been the traditional orthodox interpretation, one held by the majority of both Jews and Christians for over seventeen hundred years, as even noted critical liberal Biblical scholars and commentators admit:
“IV. Traditional Interpretations. The earliest interpretations and adaptations of the ‘one like a human being,’ Jewish and Christian alike, assume that the phrase refers to an individual and is not a symbol for a collective entity.263
In the Similitudes of Enoch (1En 46:1), the white-headed ‘head of days’ is accompanied by one ‘whose face had the appearance of a man, and his face [was] full of grace, like one of the holy angels.’ He is explicitly called ‘messiah,’ or anointed one, in 48:10; 52:4, and ‘his name was named’ before creation (48:3).
In 4 Ezra 13 the man who rises from the sea and flies with the clouds of heaven is also a messianic figure, but like ‘that Son of Man’ in the Similitudes, he is a preexistent, supernatural figure (13:26; ‘This is he whom the Most High has been keeping for many ages’).
The messianic interpretation prevails in rabbinic literature 264 and remains the majority of opinion among the medieval Jewish commentators. The tradition is not entirely uniform. In some circles the two figures in Dan 7:9-14 were taken as two manifestations of God, apparently in reaction to the heretical view that they represented two powers in heaven. The collective interpretation is not clearly attested in Jewish circles until the Middle Ages…
In summary, the traditional interpretations of the ‘one like a human being’ in the first millennium overwhelmingly favor the understanding of this figure as an individual, not as a collective symbol. The most usual identification was the messiah, but in the earliest adaptations of the vision (the Similitudes, 4 Ezra, the Gospels) the figure in question had a distinctly supernatural character.” (Hermeneia – A Critical and Historical Commentary on the Bible, A Commentary on the Book of Daniel, by John J.
