Big, BIG logical non sequitur. Mary was the host mother of Jesus' body, not His Personality, not His soul and spirit that preexisted the body given to Him by The Father:
"Wherefore when he cometh into the world, he saith, Sacrifice and offering thou wouldest not, but a body hast thou prepared me:" (Heb 10:5 AV).
(That, by the way, is the First Christmas Carol, IMO.)
Mary was not the mother of The Jehovah that entered into that body. He existed before The Beginning of time, dimensions, and matter. Mary's predecessors were made in Elohim's image, not vice versa.
Your thoughts are so sad.
“Since Mary is Jesus’ mother, it must be concluded that she is also the Mother of God: If Mary is the mother of Jesus, and if Jesus is God, then Mary is the Mother of God. There is no way out of this logical syllogism, the valid form of which has been recognized by classical logicians since before the time of Christ.”
And:
“The Nestorian claim that Mary did not give birth to the unified person of Jesus Christ attempts to separate Christ’s human nature from his divine nature, creating two separate and distinctpersons—one divine and one human—united in a loose affiliation. It is therefore a Christological heresy, which even the Protestant Reformers recognized. Both Martin Luther and John Calvin insisted on Mary’s divine maternity. In fact, it even appears that Nestorius himself may not have believed the heresy named after him. Further, the “Nestorian” church has now signed a joint declaration on Christology with the Catholic Church and recognizes Mary’s divine maternity, just as other Christians do.
Since denying that Mary is God’s mother implies doubt about Jesus’ divinity, it is clear why Christians (until recent times) have been unanimous in proclaiming Mary as Mother of God.
The Church Fathers, of course, agreed, and the following passages witness to their lively recognition of the sacred truth and great gift of divine maternity that was bestowed upon Mary, the humble handmaid of the Lord. “
