Mary is Mother of God
In order to save mankind from the death’s horrors of and from the sin, the Son of God had to become incarnate, poor pilgrim on the earth Himself. He needed a Mother.
How perfect this privileged woman had to be! God had been preparing Her in wisdom for all the eternity. And it was Mary, the one who is dismayed and humbles herself before the announcing Angel, but shouts to Heaven: “Here is the maid of the Gentleman! Fiat!” and the sweet and tremendous mystery is performed, God’s Son is the Son of Mary.
