I disagree. This is good example of a human become a God or Goddess in mythology as being born without sin (above all humans), Mother of God and Queen of Heaven. Just because the Roman Church claims something to self-define it self under separate rules than anyone else does make it so. Considering the images of Mary bear a striking resemblance to the Roman Goddess is not a coincidence.
From:
Theotokos: How the Mother Goddess became Mary
Mary becomes Mother of God: The year 431 A.D. was a momentous one in the history of the Queen of Heaven. That’s the year the church fathers, meeting in Ephesus in modern day Turkey, officially declared that
Mary is Theotokos, literally, in Greek, the one who gave birth to God. More commonly her title is paraphrased as Mother of God. This was an important political step, as it clarified for the theologians that Jesus was both God and man. Perhaps just as importantly, however, it pacified the people, who were demanding that Mary be acknowledged as a divinity.
Technically, the church denied Mary as divine, as a Goddess, but in practical terms,
it conveyed a sense of holiness which made her a viable rival to that other popular Roman/Greek/Egyptian hybrid Goddess of the time, represented variously as Diana, Cybele, and Isis. As a result of their decision, Mary’s divinity has been able to shine through in art and writing and devotion of those who love her.
Beautiful artwork throughout the world depicts Mary holding her infant son exactly as Isis had done for thousands of years before her. Many a home today displays a Christmas creche with Mary tenderly watching over the babe who is God incarnate. Mary is referred to as Mother of God in both the Roman Catholic and Eastern Orthodox churches, which together represent the majority of the Christian faithful."
Canaanite, Ugarit, Babylonian, Roman and Greek mythology are woven all through Christianity.
We also disagree that the Trinity, is Tritheism, therefore our disagreement continues.
