It is NOT "the Son of Man"! Quit capitalizing Man! It is written "the Son of man", that is short form for "THE SON (of God) of man (or human)". "THE SON" because Jesus was and is God's ONLY begotten Son that is why it is NOT written "a Son of man" . Jesus had half-brothers so "the Son" would not be accurate if referring to his earthly family. As you can plainly see in all these verses copy and pasted from the KJV, ONLY "Son" has a capital "S", "man" has a small "m" for a reason. It does not say "a Son of a man" or "a Son of man" but " THE SON - of man", "of man" because Jesus had an eartly woman as His mother which made Him human with flesh and blood.
