Catholics understand the dual nature of Jesus as human and divine. It was stated that the Word became Flesh. The two natures are combined and not separate.
So through the grace and actions of God, Mary became the Mother of God, Jesus, both his human and divine natures.
So do you not believe that God can do all things? Do you not believe that Jesus is both God and human? So do you split Jesus in half and deny that He is both? Your logic and reason escapes me.
Did you listen to whole interview of Tim Staples where he explains the importance of Mary and the need to accept her as the Mother of God?
Lots of people do. That's why the term *mother of Jesus* is accurate and *mother of God* is not.
