How do you divide Christ Jesus' human nature from His God nature? BTW, Mary didn't just bear Him, give birth to Him; the Bible speaks of "His mother." Even the angels say, "Take the Child and His mother" etc. Matthew 2:10-12, 13-15, 19-20. The wise men worshipped the Child, not His mother. Same here.
No need to "divide" them. Christ has a dual nature, as affirmed in the Athanasian Creed.
Christ received His divine nature from His perfect, divine Father, and His human nature from his human, fallible mother.
Here's a good explanation. Read it and learn...
When Elizabeth heard Mary’s greeting, the baby leaped in her womb, and Elizabeth was filled with the Holy Spirit. 42 In a loud voice she exclaimed: “Blessed are you among women, and blessed is the child you will bear! 43 But why am I so favored, that the mother of my Lord should come to me? 44 As soon as the sound of your greeting reached my ears, the baby in my womb leaped for joy. 45 Blessed is she who has believed that the Lord would fulfill his promises to her!”When the wife of a Jewish priest is talking about "her Lord" she's referring to the Lord God of Abraham, Isaac, and Jacob, the Lord of Glory, the Master of the Universe and she wasn't making any silly distinctions about "human nature" versus "divine nature" and the former being something to be described by the word "merely." Mary is the only mother God ever had. He was God-incarnate from the moment of conception; he experienced gestation and birth and was nursed and cared for by his mother (leaving aside for the moment the much later claim that he went to ex utero from in utero in an unusual way--to preserve a concept of virginity that is as bizarre as your concept of what motherhood entails).
