The Virgin Mary gave birth to a Person . That Person (the child Jesus) was both God and man. She is thus birth giver of God or Theotokos. He took His flesh from her and while His divinity obviously didn't originate from her she is still the mother of God because God the Son dwelt in her womb and she gave birth to him. This is basic Christology 101 and most Protestants traditionally accepted this**. Now a days some of them are so opposed to anything that honors the Virgin Mary that they often fall into Nestorianism to combat it. They bring back that old argument of Nestorius that the Virgin Mary is merely mother of His humanity. As if only the human nature existed in her womb (separated from His divinity) and not the Person of Christ who is BOTH man and God.
The ironic thing is even the so called "Nestorian Church" (The Assyrian Church of the East) has come to an agreement with the Catholic Church that Mary can be called "Theotokos" and that the term is accurate! So these Protestants are even more Nestorian than the "Nestorian Church" !
** Look what the Protestant reformers themselves said about her:
"She is rightly called not only the mother of the man, but also the Mother of God ... It is certain that Mary is the Mother of the real and true God."
"It is an article of faith that Mary is Mother of the Lord and still a Virgin."
Martin Luther
"Elizabeth called Mary Mother of the Lord, because the unity of the person in the two natures of Christ was such that she could have said that the mortal man engendered in the womb of Mary was at the same time the eternal God."
John Calvin
"It seems to me impossible that we should obtain the reward of Heaven without the help of Mary. There is no sex or age, no rank or position, of anyone in the whole human race, which has no need to call for the help of the Holy Virgin."
John Wycliffe
"I esteem immensely the Mother of God, the ever chaste, immaculate Virgin Mary."
Ulrich Zwingli
