The consecration of Russia to the Immaculate Heart was reportedly requested by Our Lady on several occasions beginning in Fatima, Portugal in 1917. This consecration as requested by Our Lady has never been performed.
The three children Lucy, Francisco and Jacinta said that in the apparition on June 17, 1917, the Virgin said to them:
I shall come to ask for the Consecration of Russia to my Immaculate Heart. If people attend to my requests, Russia will be converted and the world will have peace.”
They said that on July 13, 1917 the Virgin told them:
God wishes to establish in the world devotion to my Immaculate Heart. If what I say to you is done, many souls will be saved and there will be peace. The [First World] war is going to end; if people do not cease offending God, a worse one will break out during the pontificate of Pius XI. When you see a night illumined by an unknown light, know that this is the great sign given you by God that He is about to punish the world for its crimes, by means of war, famine, and persecutions of the Church and of the Holy Father. To prevent this, I shall come to ask for the consecration of Russia to my Immaculate Heart....
If my requests are heeded, Russia will be converted, and there will be peace. If not, she will spread her errors throughout the world, causing wars and persecutions of the Church. The good will be martyred, the Holy Father will have much to suffer, and various nations will be annihilated. In the end, my Immaculate Heart will triumph. The Holy Father will consecrate Russia to me, and she will be converted, and a period of peace will be granted to the world.”
Sr. Lucy reported that the Virgin of Fatima appeared to her again on June 13, 1929, and said:
This is the moment when God asks
1. the Holy Father to make,
2. in union with all the bishops of the world,
3. the consecration of Russia to my Immaculate Heart.
He promises to save it by that means. So many are the souls which the justice of God condemns for sins committed against me that I come to ask for reparation. Sacrifice yourself for this intention and pray.”
And Sr. Lucy added:
Later on through an intimate communication, Our Lord said: ‘They have not chosen to heed my request… As the King of France, they will regret it and then will do it, but it will be too late. Russia will already have spread her errors throughout the world, provoking wars and persecutions against the Church, the Holy Father will have much to suffer.’”
Sr. Lucy asked our Lord why He would not convert Russia without the solemn public consecration of that nation specifically. Jesus answered:
Because I want My whole Church to acknowledge that consecration as a triumph of the Immaculate Heart of Mary, so that it may extend its homage later on, and put the devotidevotion to this Immaculate Heart beside the devotion to My Sacred Heart.”
Consecration never completed
In response, Popes Pius XII (1942), John Paul II (1984) and Francis (2013) consecrated the world to the Immaculate Heart, with Pius XII also specifically consecrating “the peoples of Russia” in 1952.
However one can dispute that a valid consecration of Russia, fulfilling the requirements of the apparition at Tuy, has been carried out since the consecration has never been performed in union with all the Catholic bishops of the world as was requested, and that the specific mandate “Consecration of Russia” is not expressed verbatim in the wording.
