My view:
Mary is the mother of Jesus human nature. Yes human nature, when people have a son they only make the body(this case the Holy Spirit and Mary),
This is the exact heresy that was popular at the time, and the reason for which the title Theotokos was given to her. Like all the Marian doctrines, it was defined because of Christ, to clarify the Teaching of the Apostles concerning Him.
When you read the history of the early heresies, you will see that this point was, indeed, argued vigorously. In the end, the Church proclaimed the teaching of the Apostles that Jesus is fully God, and fully man, two natures in one Person.
I am not sure why you think the soul of a person is not also part of their personhood, but when a person is born, they are body, soul, and spirit. We do not know at which point the soul and spirit are joined with the body, but to be on the safe side, we consider that life begins at the moment of conception. Human life is comprised of all these elements. A mother gives birth to a person, body, soul, and spirit - not a “nature”. Indeed, Jesus human nature did come from Mary, whereas His divine nature He possessed forever. In Him, these two natures were joined in one Person.
I agree with you that it is a great mystery, and one quite beyond the feeble comprehension of our limited human minds. However, we do know certain things by revelation, and that Mary is the Mother of God is one of those revelations.
Code:
Also remember Jesus gave up His God status when He came to Earth.
I am not sure what this means to you. Do you think that Jesus did not have a divine nature?
, Mary was His mother in His lifetime as a human because He already was, “before Abraham I was”. So Mary is the mother of Jesus human nature.
God bless.
Mary is the mother of Jesus, His person. That means, she is the mother of the Son of God, who emptied Himself, and became flesh, and dwelt among us. To deny this is to deny the incarnation, which is why the term was chosen.
