What unites heretics of all times is their intolerance of the cult reserved for the Blessed Virgin Mary and the Marian doctrine it presupposes and of which it is the liturgical expression. Moreover, this is not surprising: Satan sees in the Mother of God she who in Her Son has crushed the head of the Ancient Serpent, she who in the course of History has defeated the assaults of Hell against the Church and who at the end of time will achieve the final victory over the Antichrist and Satan.
The Most Holy Trinity is pleased to share the work of Redemption with Our Lady, to Whom it has granted privileges that no creature has ever even been able to conceive of, the first of which is having preserved Her from original sin and having preserved her Virginity intact before, during, and after the birth of the Savior. In Mary, the New Eve, Satan sees the creature who triumphs over him, making reparation for the temptation and fall of Eve: this is why She is Co-Redemptrix, in union with Christ the New Adam.
Filial devotion to the Blessed Mother is very difficult to eradicate among the Christian people: even after the Protestant pseudo-reform and after the Anglican schism, devotion to the Virgin survived, to the point of requiring particular efforts to erase it: it is difficult to rip out love for the heavenly Mother from the hearts of the simple when it is so spontaneous, natural, and comforting. I think of the cases of heretics who returned to the womb of the Church thanks to devotion to Mary Most Holy, even if only because of one Hail Mary that their mother had taught them to say as little children. And this devotion is simple, humble, sweet, confident, and most pure; it does not decrease in those who are ignorant of the lofty peaks of theological doctrine, because it sees us as children and Her as Mother, beyond everything else, recognizing Her as the Savioress [Salvatrice], the Merciful One, the Advocate, to whom we always have recourse, despite all of our faults, even when it frightens us to raise our gaze towards Her Divine Son whom we have offended. “Behold Your Mother” (Jn 19:26-27).
This is why Satan hates “the Lady,” as he calls Her during exorcisms: he knows all too well that the power of Jesus Christ not only is not in the least obscured by His Mother but rather it is exalted by Her, because while Satan’s pride has sunk Him into Hell, Her humility has exalted Her above all creatures, allowing Her to carry in Her womb the Son of God whose Incarnation, in which he assumed a human body, Lucifer could not tolerate.
The decline of Marian devotion after the Council is only the latest expression, and I would say the most aberrant and scandalous, of the aversion of Satan towards the Queen of Heaven. It is one of the signs that that assembly did not come from God, just as those who dare even to question the titles and merits of the Most Holy Virgin do not come from God. On the other hand, what son would allow his own mother to be put down in order to please his father’s enemies? And how much more serious is this abject complicity with heretics and pagans when the honor of the Mother of God and our Mother is at stake? The Beloved of the Trinity, She has been chosen by God the Father as His Daughter, by God the Son as His Mother, and by God the Holy Spirit as His Spouse.
I believe that the gift of my “conversion” – of my becoming aware of the conciliar deception and the present apostasy – became possible thanks to my constant devotion towards the Blessed Mother, which I have never ceased to have. I carry the vivid memory of the recitation of the Holy Rosary ever since I was a child, when during the Allied bombardment – in April 1944 – my mother carried me into the air-raid shelter under our house in Varese and held me close to her as she invoked the protection of the Madonna, whose image was illuminated by a small lamp. The blessed “Crown” of Our Lady [the Rosary] has always animated my prayer.
It will be the Holy Virgin, with Her heel, who will crush the infernal idols that infest and profane the Church of Her Son; She is the one who will restore the regal Crown to Her Son, ousted by His own Ministers; She is the one who supports and protects the Good in this hour of darkness; She is the one who implores the graces of conversion and repentance for sinners.
