Is it because the clerics of Holy Mother Church had been unfaithful and remiss in their sacred offices and duties that our Lord has deigned to visit us with such calamities? Perhaps Our Lady of the Rosary at Fatima meant to warn them of this very thing in the Third Secret, that they may amend and repair for their negligence, which allowed modernism to pervert the clergy and layfolk.
I don't agree with this.
I personally believe the
Third Secret was specifically addressed to the upper hierarchy, whilst the message of Our Lady of the Rosary at Fatima in its entirety was addressed to the whole of Christendom (clergy and laity). I do not see how Our Lady would have kept the Third Secret unpublished until 1960 if the contrary were true. Sr. Lucia did not get to publish it, but she gave enough information for us to discern its contents. Moreover, Sr. Lucia herself became the embodiment of the Third Secret (cf. Apoc. cap. x., 9-10; Ezech. cap. iii., 1 sqq.): knowing what happened to her would be a key to discovering the Third Secret's contents. The contents of the Secret are to be found in various places of Holy Writ (such as the Prophecies of Daniel, Ezechiel, Jeremias, Lamentations, and Habacuc; the Books of Kings; the eschatological discourse of Our Lord in the holy Gospels; the Apocalypse of St. John, etc.). I believe the Third Secret foretold the present-day crisis assailing Holy Mother Church.
Sr. Lucia's extraordinary vocation was to be a marvelous coalescence of the lives of the Seraphic Virgin, St. Catherine of Sienna, and of the Little Flower, St. Thérèse of the Child Jesus: a victim soul who would make reparation through horrible suffering for the iniquities of the faithful in a hidden, contemplative life, particularly in impetration for the liberty and exaltation of Holy Mother Church in the triumph of the Immaculate Heart of Our Blessed Mother -- which is the reign of the Sacred Heart of Jesus all the more perfectly established, according to the doctrine of St. Louis-Marie.
The same could be said of Padre Pio, though in a more extraordinary way.
The fruits of both their apostolates of prayer and sacrifice can be seen in the manner in which a great number of the faithful persevere in the practice and profession of the Catholic faith, particularly in the devotion to the Holy Rosary.
These are just my personal observations.
