No, it does not. Jesus the man was born. The Deity is eternal and has no birth nor death.
But Jesus by his own words said "I and the Father are one". Ergo, Jesus is Lord. And Mary is mother of the Lord Jesus in the flesh as Elizabeth addressed her.
Now here I am defending what is true in the Catholic church. There are many things that I don't accept any more and some I'm not sure of.
Who told you to divide the man from the deity? God didn't. Jesus said when you see Him, you see the Father. He is fully man AND fully divine... there is no division within Him.
