She is definitly the mother of God's Person of Jesus while he was on Earth. But so what? It's not like she was there before Jesus or before the other persons of the trinity. She did not gave God anything, which he could not have had otherwise. She was very blessed because she was allowed to experience the most time with Jesus incarnate. Also she was very brave and faithful! But I don't see, why the earthly mother of Jesus should get any special treatment in comparison to other faithful christians.
