You can call me Alex.
The Eternal God existed before Mary, and Mary gave birth to Him.
Thank you Alex.
I am glad that you agree that the Eternal God existed prior to the birth of Mary.
It is therefore necessary to conclude that you mean something different when you quote the "Mother of God" forumlation, for it is not possible that it means that Mary pre-existed God and gave rise to this God that pre-existed her. You mean what you are saying in formulaic language and that is all I need to know.
