Mary, Mother of God, pray for us
By taking our nature and offering it in sacrifice, the Word was to destroy it completely and then invest it with his own nature, and so prompt the Apostle to say: This corruptible body must put on incorruption; this mortal body must put on immortality.
This was not done in outward show only, as some have imagined. Our Savior truly became man, and from this has followed the salvation of man as a whole. Our salvation is in no way fictitious, nor does it apply only to the body. The salvation of the whole man, that is, of soul and body, has really been achieved in the Word himself.
What was born of Mary was therefore human by nature, in accordance with the inspired Scriptures, and the body of the Lord was a true body: It was a true body because it was the same as ours. Mary, you see, is our sister, for we are all born from Adam.
The words of St John, the Word was made flesh, bear the same meaning, as we may see from a similar turn of phrase in St Paul: Christ was made a curse for our sake. Man’s body has acquired something great through its communion and union with the Word. From being mortal it has been made immortal; though it was a living body it has become a spiritual one; though it was made from the earth it has passed through the gates of heaven.
