No demand. You object to "mother of God" because some illiterate Christians might think Mary preexisted God, but you insist on the attribute of God that grossly distorts His image.
"No demand."
Even before the Law God was demanding a "ransom" for sin.
Job 33:23, "If there be a messenger with him, an interpreter, one among a thousand, to shew unto man his uprightness: Then he is gracious unto him, and saith, Deliver him from going down to the pit: I have found a ransom. His flesh shall be fresher than a child's: he shall return to the days of his youth: He shall pray unto God, and he will be favourable unto him: and he shall see his face with joy: for he will render unto man his righteousness."
