Father Alonso, the official Fatima archivist had this to say on the Third Secret:
‘In Portugal, the dogma of the Faith will always be preserved’: The phrase most clearly implies a critical state of Faith, which other nations will suffer, that is to say, a crisis of Faith; whereas Portugal will preserve its Faith.3
In the period preceding the great triumph of the Immaculate Heart of Mary, terrible things are to happen. These form the content of the third part of the Secret. What are they?
If ‘in Portugal the dogma of the Faith will always be preserved,’ ... it can be clearly deduced from this that in other parts of the Church these dogmas are going to become obscure or even lost altogether.4
Thus it is quite possible that in this intermediate period which is in question (after 1960 and before the triumph of the Immaculate Heart of Mary), the text makes concrete references to the crisis of the Faith of the Church and to the negligence of the pastors themselves.5
One conclusion does indeed seem to be beyond question: the content of the unpublished part of the Secret does not refer to new wars or political upheavals, but to happenings of a religious and intra-Church character, which of their nature are still more grave.6
Knowledgeable Church authorities have confirmed Father Alonso’s conclusions about the Third Secret, that it concerns an unprecedented loss of faith, an apostasy, from which Portugal will be preserved. In 1984 the Bishop of Fatima said, "the loss of Faith of a continent is worse than the annihilation of a nation; and it is true that Faith is continuously diminishing in Europe." And in his 1984 interview with Vittorio Messori, Cardinal Ratzinger confirmed this conclusion when he said that the final part of the Secret speaks of "dangers threatening the faith and life of Christians, and therefore the world."
Finally, we know that the fulfillment of the prophecy of the Third Secret began to be realized in 1960 because when Sister Lucy was asked why the Third Secret was to be revealed no later than 1960, she responded "because it will be clearer then." Since 1960 we have seen the prophecy of the Third Secret unfold before our eyes, and it is clear that since that time the world has been progressively suffering from a terrible loss of faith.
