The five First Saturdays Devotion requested by Our Lady of Fatima is connected to the consecration of Russia to the Immaculate Heart of Mary.

July 1917 apparition. At this apparition, Our Lady showed hell to the children. Afterward, she said “You have seen hell where the souls of poor sinners go. To save 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.” *

Mary went on to say a worse war would break out if people don’t stop offending God. And then she said “To prevent this, I shall come to ask for the consecration of Russia to My Immaculate Heart, and the Communion of Reparation on the First Saturdays. 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.”

On March 19,1939, Sister Lucia said “Whether the world has war or peace depends on the practice of this devotion, along with the consecration of Russia to the Immaculate Heart of Mary.”

Our Lady made the request to Lucia on Dec. 10, 1925. The request is:

With the intention of making reparation for the offenses against the Immaculate Heart, we are asked to do the following on 5 consecutive first Saturdays (source: https://www.bluearmy.com/first-saturday-devotion/):

• Go to Confession (may be 8 days before or after, if you are in a state of grace)

• Receive Holy Communion (can be received at a Saturday evening anticipatory Mass).

• Pray five decades of the Rosary

• Keep Our Lady company for 15 minutes while meditating on one or more of the mysteries of the Rosary.

In addition to peace, Our Lady has promised “final perseverance” at the hour of death to those who fulfill the Five First Saturday’s devotion.
