Yes, I'm well aware that Luke also traces Christs genealogy back to Adam. In my question to you I pointed that out. Like I stated God is not biology and Joseph is the step father of Jesus. His real Father is God. Why do you think that Jesus referred to Himself on numerous occasions as the "Son of God" and as the "Son of Man?"
He's the Son of God on His Fathers side which is deity. He's the Son of Man on His mother's side which is human being. Also, Jesus was accused of blasphemy for claiming God the Father was His own Father making Himself equal with God. (John 5:17,18.) At John 10:33 the Jews again accused Jesus of blasphemy for making Hinmself out God when Jesus stated at John 10:30, "I and My Father, we are one."
Jesus quotes Psalm 82:6 to the Jews and at vs 36 He says, "do you say of Him whom the Father sanctified and sent into the world. You are blaspheming because I said, "I am the Son God?" And at the trial of Jesus at Matthew 26:63 the high priest Caiaphas ask Jesus to swear as to His identity . "I adjure You by the living God that You tell us whether You are the Christ, the Son of God."
At Luke 22:70 Jesus says, "Yes, I am." The high priest Caiaphas is asking the one person of Jesus Christ two questions. (1) are you the Christ/Messiah and (2) are you the Son of God. Now think for a second? Why would the high priest ask Jesus and accuse Him of blasphemy if He was the Son of God when the Jews themselves also believe their the sons of God as well?
I found the following article on this subject and some of it is "sort of speculation" and some of it makes sense. I prefer the following view because it does make sense.
Lesson 14: The Genealogy of Jesus (Luke 3:23-38) | Bible.org
"A further support for this view is that it fits Luke’s purpose. Since he was writing for a largely Gentile audience, Luke wanted to trace Jesus’
physical descent (which had to be through Mary), showing that He was not only the son of David, but also son of Abraham (through whose descendants God promised to bless the nations), and son of Adam (which relates Jesus to the entire human race). Matthew, on the other hand, writing for primarily a Jewish readership, wanted to authenticate Jesus as the legal heir of the throne of David through Solomon, who was Joseph’s ancestor. Since Jesus was Joseph’s adopted son, Matthew traces the legal right to the throne through him."
IN GOD THE SON,
