See my post nine.
You are correct that Mary is not a goddess.
But she is presented as a goddess by some.
See this example: “her immaculate conception, perpetual virginity, assumption into heaven, her Queenship, and her role in God’s plan of salvation as Co-redemptrix”
Those are properties of a goddess.
By whom? If you are asserting she is viewed by Catholics as a goddess, you are either ignorant, or deliberately uttering calumnies. There really is no third choice, so which is it? Or perhaps you're referring to some outside of the Catholic church who view Mary as a goddess. Perhaps you've seen, "Mists of Avalon," one too many times (Hint: It's fiction).
"...Those are properties of a goddess."
That she has a role in God's plan makes her a goddess? That would make you and I goddesses as well; we all have a role in God's plan. Mary's role is a quite unique and special one, to be sure, but anybody reading the first chapter of Luke would know that. If Mary finds special favor with God, I suspect it's ok for the rest of us to view her the same way...
