He said to him, "Most assuredly, I tell you, hereafter you will see heaven opened, and the angels of God ascending and descending on the Son of Man."
The answer to the first question is an emphatic negative.  Jesus meant by the title "Son of man" to affirm his deity and Godhead just as dogmatically as the title "Son of God" could have done it, but with the additional advantage of stressing his unique relationship to the human race as well. It is evident that THE Son of man cannot be any mortal being.  Dummelow pointed out that the Greek words so translated cannot mean "A Son of man," but definitely and emphatically, "THE Son of man."[58]
