Likewise, just as the air that is in the balloon continues to also exist outside of the balloon, so likewise the Spirit of God continues to exist apart from the incarnation as the omnipresent Spirit. This is not what I am saying. I believe that Mary contributed to part of Jesus' humanity. That God also had to have contributed to Jesus' humanity is evident in that if Mary alone would have added the human element to Christ's existence, Jesus could have only been a female. All that Mary's egg could have offered were X chromosomes.
X chromosomes produce females.
It takes the presence of Y chromosomes to produce a male child. Only men have this Y chromosome. Without a contribution of this Y chromosome Jesus could not have been born a human male. The only answer can be that it was supplied by the Holy Ghost in the conception. Because God contributed an element necessary to Jesus' human existence, it is necessary to confess that Jesus received part of His humanity from the Father.
