Why did the Lord Jesus the Christ refer to Himself as the Son of Man?

Because he (God himself) had appeared in a humble human form. Please ref Philippians 2:6-8 and let the Bible answer your question.

God bless you brother.

The thing you call: lord jesus chris, can't refer itself as ' something '. Only its creator is able to do that, but only via its adventures.

Many novels have been written about it, the more well-known is called: Bible.

if He were to explicitly use the reference 'son of God' it would have been a sin.  The bible clearly shows that when asked if he was the son of God, He responded by saying 'if that’s what they say, it must be true'.  There are many instances where he used words and phrases which only the Son of God could use, and it was on the basis of those sayings that the Pharisees could validate their charges against Him. 

Because he came to earth as God and Man, born of the human, Mary.

Follow the lineage to Adam the first man.

Goat Herders thought it was cool 

because He was born fully mortal man.......

So that someone would look in the bible 

to see if he was lying or not. 

He also referred to Himself as the Son of God showing both His humanity and divinity

He didn't know who his real daddy was....
