In 1689, our Lord gave a message to St. Margaret Mary Alacoque that the King of France was to consecrate France to His Sacred Heart. The king disobeyed our Lord's request and exactly one hundred years later, the French Revolution began. The Revolution in France, contrary to what we were all taught in school, caused so much devastation and destruction to the French way of life, the Catholic Church in France, and the lives of many French priests and nuns. (A side note: St. John Marie Vianney received his First Holy Communion in a barn in hiding as a direct result of the French Revolution.)
Imprisoned during the Revolution and shortly before losing his head at the guillotine, the French king finally made the consecration of his nation in obedience to God's request. The French Revolution truly devastated the Church in France and brought many, many evils. In many ways, the revolution we are seeing today (from the Errors of Russia) is but a continuation of the French Revolution on a global scale.
We are nearing one hundred years that the popes have disobeyed Our Lady at Fatima. They have failed to reveal the full text of the Secret of Fatima (in totu) and they have not consecrated Russia to Our Lady's Immaculate Heart in the manner requested by Heaven. Our Lord told Sr. Lucia that the pope would eventually consecrate Russia, but it would be too late, like the French king. Terrible chastisements have already inflicted our world and worse ones are coming so long as this disobedience continues. Terrible wars and natural disasters are on the horizon, nations will be annihilated, and the True Faith will be completely lost in many places. We must each do our best to do as our Lady asked.
Our Lady has promised that once she is obeyed there will be a time of peace in the world (complete peace!). Russia will convert en masse to the one true and only Catholic Church, outside of which there is no salvation. A period of glorious flourishing will occur for mankind and the Catholic Church. The Immaculate Heart of Mary will be honored everywhere. Let us pray that this glorious restoration will occur soon, and let us do our part. (Small note: The Miracle of Fatima took place on 13 Oct 1917, however, it was not until 1929 that Our Lord told Sr. Lucia that now was the time for the Holy Father to consecrate Russia.)
It is extremely important for every Catholic to be familiar with Our Lady's Message and strive to live it as best as possible. This includes (1) the Daily Recitation of the Rosary, (2) The First Saturday Devotion, (3) Making acts of Reparation to her Immaculate Heart (and the Sacred Heart and Blessed Sacrament), (4) Doing Penance, especially the duties of our state in life, (5) Wearing her Brown Scapular, and (6) Praying and doing penance for the Pope, especially so that the Pope, in union with all the bishops of the world, will consecrate Russia to the Immaculate Heart of Mary.
Heaven gave us several unique and special prayers at Fatima. We should pray these often as well. You can find them HERE (just scroll down a bit).
