Today, 8 December, we celebrate the Solemnity of the Immaculate Conception. I wish you all a Blessed and Holy Feast Day!
Pope Benedict XVI, Angelus, 8 December 2012
“I would like to emphasise that Mary is Immaculate through a freely given gift of God’s grace, which, however, found perfect willingness and cooperation in her.  It is in this sense that she is “blessed” because “she believed” (Lk 1:45) and because she had steadfast faith in God.  Mary represents that “remnant of Israel”, that holy root which the Prophets proclaimed.  The promises of the Old Covenant find a ready welcome in her.  In Mary, the Word of God is met with listening, acceptance and a response, He encounters that “yes” which enables Him to take flesh and to come and dwell among us.
In Mary, humanity and history are truly opened to God, they welcome His grace and are prepared to do His will.  Mary is a genuine expression of Grace.  She represents the new Israel, which the Scriptures of the Old Testament describe with the symbol of the bride. And St Paul takes up this language in his Letter to the Ephesians where he speaks of marriage and says “Christ loved the Church and gave himself up for her, that he might sanctify her, having cleansed her by the washing of water with the word, that he might present the Church to himself in splendour, without spot or wrinkle or any such thing, that she might be holy and without blemish” (5:25-27).  The Fathers of the Church developed this image and thus the Doctrine of the Immaculate Virgin first came into being with reference to the Church virgin-mother and, subsequently, to Mary.  Thus Ephraim the Syrian writes poetically:  “Just as [it was] because these bodies themselves have sinned and are themselves dying, that the earth, their mother was also accursed (cf. Gen 3:7-19), because of this body which is the incorruptible Church, her land was blessed from the outset.  This land is the body of Mary, a temple in which a seed was sown” (Diatessaron 4, 15: sc 121, 102).
The light that shines from the figure of Mary, also helps us to understand the true meaning of original sin.  Indeed that relationship with God which sin truncates is fully alive and active in Mary.  In her there is no opposition between God and her being, there is full communion, full understanding.  There is a reciprocal “yes” – God to her and her to God.  Mary is free from sin because she belongs entirely to God, she empties herself totally for Him.  She is full of His Grace and of His Love.
To conclude, the Doctrine of the Immaculate Conception of Mary expresses the certainty of faith that God’s promises have been fulfilled and that His Covenant does not fail but has produced a holy root from which came forth the blessed Fruit of the whole universe, Jesus the Saviour.  The Immaculate Virgin shows that Grace can give rise to a response, that God’s fidelity can bring forth a true and good faith.”
Room of the Immaculate Conception
Following the proclamation of the dogma of the Immaculate Conception by Pius IX, which took place on 8 December 1854, the pontiff decide to celebrate the event with a cycle of frescoes.
The large room adjacent to the Raphael Rooms was chosen and the task was assigned to Francis Podesti (1800-1895), a painter originally from Ancona but rooted in the Roman artistic and academic panorama.  The artist, along with his team of workers, worked on the commission from 1856 to 1865, planning it and following its execution in all its aspects –  the wooden doors and window frames and the inlaid marble work, as well as the installation of the Roman mosaic from Ostia Antica, purchased specifically for this space.
The pictorial decoration proceeds from the ceiling, with allegorical scenes alluding to the virtues of the Virgin;  it continues along the northern wall with the homage of the continents to the Church enthroned;  it continues on the west wall, devoted to the Discussion of dogma in St Peter’s Basilica and concludes on the east wall, with the Coronation of the Image of Mary, an event following the Proclamation, which took place in St Peter’s.  Podesti, who was present, included a self-portrait here.
