Mary, the Blessed Virgin ("all generation shall call me blessed"), is the Mother of the Man-God, the Person Jesus Christ. As Jesus is True God, and He is one Person, not two, Mary is the Mother of God. She is NOT the origin of God, but she is the mother of the person who is the Man-God, Jesus Christ, who became incarnate through the power of the Holy Ghost.
“She is NOT the origin of God, but she is the mother of the person who is the Man-God, Jesus Christ, who became incarnate through the power of the Holy Ghost.”
I agree. But we have to be careful when we say she is the “Mother of God.” Many take this to mean she is the intercessor, the co-redemptrix or sinless and deserving of worship. These characteristics belong to Jesus Christ.
Luke 1
46 And Mary said: “My soul exalts the Lord,
47 And my spirit has rejoiced in God my Savior.
48 “For He has had regard for the humble state of His bondslave; For behold, from this time on all generations will count me blessed.
49 “For the Mighty One has done great things for me; And holy is His name.
50 “AND HIS MERCY IS UPON GENERATION AFTER GENERATION TOWARD THOSE WHO FEAR HIM.
51 “He has done mighty deeds with His arm; He has scattered those who were proud in the thoughts of their heart.
52 “He has brought down rulers from their thrones, And has exalted those who were humble.
53 “HE HAS FILLED THE HUNGRY WITH GOOD THINGS; And sent away the rich empty-handed.
54 “He has given help to Israel His servant, In remembrance of His mercy,
55 As He spoke to our fathers, To Abraham and his descendants forever.”
