The secrets guide us to conversion and a turn back to God…which is the essential message of the Gospel in general terms.
As the Vatican site states:
[left]Fatima is undoubtedly the most prophetic of modern apparitions. The first and second parts of the “secret”—which are here published in sequence so as to complete the documentation—refer especially to the frightening vision of hell, devotion to the Immaculate Heart of Mary, the Second World War, and finally the prediction of the immense damage that Russia would do to humanity by abandoning the Christian faith and embracing Communist totalitarianism.
“To save souls” has emerged as the key word of the first and second parts of the “secret”, and the key word of this third part is the threefold cry: “Penance, Penance, Penance!” The beginning of the Gospel comes to mind: “Repent and believe the Good News” (Mk 1:15). To understand the signs of the times means to accept the urgency of penance – of conversion – of faith. This is the correct response to this moment of history, characterized by the grave perils outlined in the images that follow. Allow me to add here a personal recollection: in a conversation with me Sister Lucia said that it appeared ever more clearly to her that the purpose of all the apparitions was to help people to grow more and more in faith, hope and love—everything else was intended to lead to this.
Furthermore, Sister Lucia had already given an indication for interpreting the third part of the “secret” in a letter to the Holy Father, dated 12 May 1982:
*“The third part of the secret refers to Our Lady’s words: ‘If not [Russia] 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; various nations will be annihilated’ (13-VII-1917). *
*The third part of the secret is a symbolic revelation, referring to this part of the Message, conditioned by whether we accept or not what the Message itself asks of us: ‘If my requests are heeded, Russia will be converted, and there will be peace; if not, she will spread her errors throughout the world, etc.’. *
*Since we did not heed this appeal of the Message, we see that it has been fulfilled, Russia has invaded the world with her errors. And if we have not yet seen the complete fulfilment of the final part of this prophecy, we are going towards it little by little with great strides. If we do not reject the path of sin, hatred, revenge, injustice, violations of the rights of the human person, immorality and violence, etc. *
And let us not say that it is God who is punishing us in this way; on the contrary it is people themselves who are preparing their own punishment. In his kindness God warns us and calls us to the right path, while respecting the freedom he has given us; hence people are responsible”.(5)
