Those who have a problem with seeing Mary as “Mother of God” also have a problem with Jesus Christ as both Man and God. To be mother of the flesh of Jesus is to be mother of God, since the two are inseparable by reason of assumption of humanity which God has done for the sake of saving all mortal flesh. What is not assumed is not saved by God, if Jesus was not fully God and fully man in one person we cannot say that God died on the cross for: “being found in human form he humbled himself and became obedient unto death, even death on a cross(Philippians (RSV) 2:8).
The two are yoked, his humanity and his divinity. What is predicated of the man is predicated of God. This is why the Catholic Church declares Theotokos, see the ecumenical council of Ephesus for more reasons why Catholics believe this is. To have ignorance of this role and title of Mary is to have ignorance of Christ.
It started in a.d. 431 when the Council of Ephesus declared that Mary was to be honored as Theotokos, the God-bearer or Mother of God. And we can understand that correctly, since Jesus is, in one person, both man and God. However, the term carried more than a small hint that something inherent in Mary made her enough like God to bear his Son.
Next the Catholic Church declared that Mary was conceived without original sin (Immaculate Conception) and later that she was taken up bodily into heaven immediately upon her death (Assumption). And through the years, the poor, humble virgin mother has been called Immaculate Heart, Virgin of the Golden Heart, Virgin of the Poor, Lady of All Nations, Mother of the World, Queen of Peace—even, though not yet officially, Co-Redemptrix.
How unlike the Mary of Scripture we remembered earlier. Wouldn’t she be embarrassed at the adoration and the myth making? If the next step is taken to officially declare her Co-Redemptrix, there will be no hiding the idolatry behind all the extrabiblical attributes assigned to her.
Will some in that church even know who the “other” Redeemer is supposed to be? Will it matter? Will Christmas become more of a Marymas?
You don’t have to know much Scripture to see what’s wrong here. Consider: When the angels appeared to the shepherds in Bethlehem, they proclaimed the birth of the Savior and not a word about his mother. After the shepherds saw Mary, Joseph, and Jesus, they spread the word about “the child,” not his mother. And the Magi from the east came to worship the infant King, not his mother.
Clearly, when we allow anything or anyone to draw attention away from Jesus, we miss the point of Christmas altogether. Remember for your Christmas: Mary was forever blessed. Jesus is forever the Blesser.
