It’s good to see that you agree that Mary did not contribute to the divine (God part) of Jesus so thus is not the “mother of God”.
Mary is the mother of Jesus. Mary is the mother of Emmanuel. Emmanuel is interpreted by the Holy Spirit before your very eyes as God with Us." Mary is the mother of "God with Us." Mary is the mother of God. 20 But while he thought on these things, behold, the angel of the Lord appeared unto him in a dream, saying, Joseph, thou son of David, fear not to take unto thee Mary thy wife: for that which is conceived in her is of the Holy Ghost. 21 And she shall bring forth a son, and thou shalt call his name Jesus: for he shall save his people from their sins. 22 Now all this was done, that it might be fulfilled which was spoken of the Lord by the prophet, saying, 23 Behold, a virgin shall be with child, and shall bring forth a son, and they shall call his name Emmanuel, which being interpreted is, God with us.
