“Mary was simply a nice lady, probably made it into heaven,”
“...from henceforth all generations shall call me blessed.” Luke 1:48. Sounds like much more than “nice” or “probably made it into heaven”.
“and has no other function in the Divine Scheme beyond being the mother of our Lord.”
Except that 1 Corinthians 6:3 shows that all of us who are Christians will have other functions in the “Divine Scheme”.
“Her adaptation as a Goddess is simply a conversion from paganism of the Great Mother with a thin veneer of Christian words.”
Except no one here thinks of Mary as a goddess. No one. No Catholic I have ever met thinks of her that way. So, apparently, the “conversion” you speak of has taken place in your mind and really no where else.
The Lord Himself has made it clear we are all on the same level before Him.....
Jesus answers.....as he stretched forth his hands to his disciples....”Behold my mother and brothers”.....
“Who is my mother?”....and ...”who are my brothers?”.... Whosoever shall do the will of my father who is in heaven, the SAME is my brother, and sister, ‘AND’ mother.” ...Matt 12
And further.....”My mother and my brothers are those who hear the word of God and do it”...Like 8
