It's only partial error, but it's enough.
I see you just won't step away from this hobby-horse though, not matter how many ways it's been shown (from a year or more ago?) to not be a good fit for the sought for application.
It's the syllogism itself which is the problem -- because it does not reflect the actual truth of the matter, but instead is an oversimplified version of the relationship (more on par with how strictly human relationships go, not fully God and fully human relationship).
You have not even attempted to explain how a woman can have a son who is God without being the mother of God.
Of course, there IS no way that can happen, unless 2+2=5.
