Fatima: Miracle of the Sun, this date is history

I would like finally to mention another key expression of the “secret” which has become justly famous: “my Immaculate  Heart will triumph”. What does this mean? The Heart open to God, purified by contemplation of God, is stronger than guns and weapons of every kind. The fiat of Mary, the word of her  heart, has changed the history of the world, because it brought  the Saviour into the world—because, thanks to her Yes, God  could become man in our world and remains so for all time.  The Evil One has power in this world, as we see and experience continually; he has power because our freedom continually lets itself be led away from God. But since God himself took a human  heart and has thus steered human freedom towards what is good,  the freedom to choose evil no longer has the last word. From that  time forth, the word that prevails is this: “In the world you will have tribulation, but take heart; I have overcome the world”  (Jn 16:33). The message of Fatima invites us to trust in this promise.    Joseph Card. Ratzinger Prefect of the Congregation for the Doctrine of the Faith
