…and perhaps you missed this earlier, this may help you.
,According to Matthew 5:8, the “immaculate heart” is a heart which, with God’s grace, has come to perfect interior unity and therefore “sees God”. To be “devoted” to the Immaculate Heart of Mary means therefore to embrace this attitude of heart, which makes the fiat—“your will be done”—the defining centre of one’s whole life. It might be objected that we should not place a human being between ourselves and Christ. But then we remember that Paul did not hesitate to say to his communities: “imitate me” (1 Cor 4:16; Phil 3:17; 1 Th 1:6; 2 Th 3:7, 9). In the Apostle they could see concretely what it meant to follow Christ. But from whom might we better learn in every age than from the Mother of the Lord?
…And so we come to the final question: What is the meaning of the “secret” of Fatima as a whole (in its three parts)? What does it say to us? First of all we must affirm with Cardinal Sodano: “… the events to which the third part of the ‘secret’ of Fatima refers now seem part of the past”. Insofar as individual events are described, they belong to the past. Those who expected exciting apocalyptic revelations about the end of the world or the future course of history are bound to be disappointed. Fatima does not satisfy our curiosity in this way, just as Christian faith in general cannot be reduced to an object of mere curiosity. What remains was already evident when we began our reflections on the text of the “secret”: the exhortation to prayer as the path of “salvation for souls” and, likewise, the summons to penance and conversion.
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.
