If you do not believe that God's Word and Breathe share in his divinity, then naturally it couldn't be said that Christ is God made flesh, because The Word is not divine.
But you are expressing a lot of positions that do not simply contradict what the church has always believed, but what is the testimony of scripture.
It is very necessary that Christ is God, as this ties up a line of prophecy that began when the ancient Israelites demanded a human king like everyone else.
The scriptures make it clear that Jesus Christ was born of the virgin Mary. She was not impregnated by Joseph. The church knows that Mary herself was a descendant of David through her parents Joachim and Anna. Joachim being from the tribe of Judah and a descendant of David. Anna was from the tribe of Levi.
I think it is important to note that The Catholic Church has always been the Christian Church. The thing that makes it somewhat confusing these days is that The Latin church which goes by the name "Catholic" actually broke off from the Catholic Church over a thousand years ago, and have officially been in schism for about a thousand years. Since then, they have made further innovations which make reconciliation nearly impossible. We have never accepted Papal Supremacy as a doctrine.
