Once again I repeat: The title is NOT to be found in the Bible.
I get that. The words ‘mother of God’ are not found anywhere in the Bible. As I stated in another post:
Very well. The phrase mother of God is not found anywhere in Scripture. But does the fact that a specific phrase is not mentioned make it not so? Does that mean that the Son of God is not the Second Person of the Trinity because that specific phrase is not found in the Bible?
More importantly, is the concept or the essential truth of Mary as Mother of God found in Scripture? Does Scripture contradict the teaching that Mary is the Mother of God?
There are many verses that support the teaching that Mary is the mother of God. One such verse is:
And the angel answered and said unto her, The Holy Ghost shall come upon thee, and the power of the Highest shall overshadow thee: therefore also that holy thing which shall be born of thee shall be called the Son of God.
This supports the concept that the child that shall be born was fully human and fully divine at the time of His birth. And by conceiving in her womb and bringing forth that holy thing that shall be called the Son of God, Mary did become the mother of this child in His humanity and in His divinity; that is, the mother of God incarnate.
I have not found anything in Scripture that contradicts this. It would be Scripture contradicting itself.
