Wow, pure blasphemy
Nothing blasphemous about it. (Luther didn't think it was blasphemous, either. He agreed with it. Do you want me to post the quotation?)
Is Jesus your King or isn't he? What do you call the King's mother?
I'll answer that question: in the Davidic monarchy of ancient Israel, she was called "great lady" ("gebirah" in Hebrew) and was (in protocol terms) the second most important person in the kingdom after the king himself.
