Critics define Messiah in a way which excludes Jesus which is nothing more than agenda driven scholarship.
By the way, Jesus FAILED to fulfill more of the Messianic prophecies than he fulfilled. No world peace, no universal prosperity, no Temple in Jerusalem where the sacrifices can be made in accordance with the Eternal Covenant...
Jesus failed, next Messiah wannabe, please...
'Not only Nickelsberg study of 1 Enoch but also Peter Flint's contributions on the Dead Sea Scrolls and Joseph Trafton's study of Psalms of Solomon dismantle the stereotype held by many today that ''the Jews'' were all expecting a warrior Messiah...The Apocryphon of Daniel (...4Q246) references a coming ''Son of God'' who ''will be called great'' and ''Son of the Most High''(see Luke 1:32-35)

4Q246, also known as the Aramaic Apocalypse, is one of the Dead Sea Scrolls found at Qumran which is notable for an early Messianic mention of a Son of God.
It is a single page with a short text. Column 1 (right hand) is damaged and requires some interpretative restoration. Column 2 (left hand) begins:
"He will be called the Son of God, and they will call him the Son of the Most High like a shooting star."
Even though this may be related to one like a Son of Man in Daniel 7:13-14, is interesting to note the fragment is quite like Luke 1:32-33, 35.
"[X] shall be great upon the earth.[O King all (people) shall] make [peace], and all shall serve [Him. He shall be called the Son of] the [G]reat [God], and by His Name shall He be hailed (as) the Son of God, and they shall call Him Son of the Most High like a shooting star."
In both we are told here and Luke that he will be "great"; that he will be "called" "Son of the Most High" and "Son of God."
