The reason Roman Catholicism refuses to answer the question, as I asked, is because
Speaking of the so-called 'Immaculate Conception" (and the so-called dogma of 'Original Sin'):
"... Ineffabilis Deus;
The Immaculate Conception; Pope BI. Pius IX - 1854 ...
... Our predecessors, indeed, by virtue of their apostolic authority, gloried in instituting the Feast of the Conception in the Roman Church. They did so to enhance its importance and dignity by a suitable Office and Mass, whereby the prerogative of
the Virgin, her exception from the hereditary taint, was most distinctly affirmed. As to the homage already instituted, they spared no effort to promote and to extend it either by the granting of indulgences, or by allowing cities, provinces and kingdoms to choose as their patroness
God’s own Mother, under the title of
“The Immaculate Conception.” ...
... Finally, in their desire to impress this doctrine of
the Immaculate Conception of the Mother of God upon the hearts of the faithful, and to intensify the people’s piety and enthusiasm for
the homage and the veneration of the
Virgin conceived without the stain of original sin, they delighted to grant, with the greatest pleasure, permission
to proclaim the Immaculate Conception of the Virgin in the Litany of Loreto, and in the Preface of the Mass, so that the rule
of prayer might thus serve to illustrate the rule of belief. ...
... All these things our illustrious predecessor, Alexander VII, summed up in these words: “We have in mind the fact that the Holy Roman Church solemnly celebrated the Feast of the Conception of
the undefiled and ever-Virgin Mary ... We also desired to protect this piety and devotion
of venerating and extolling the most Blessed
Virgin preserved from original sin ... we renew the Constitutions and Decrees issued by the Roman Pontiffs, our predecessors, especially Sixtus IV,[8] Paul V,[9] and Gregory XV,[10] in favor of the doctrine asserting that the soul of the Blessed Virgin, in its creation and infusion into the body, was endowed with the grace of the Holy Spirit and
preserved from original sin ...
... Even
the Council of Trent itself, when
it promulgated the dogmatic decree concerning original sin, following the testimonies of the Sacred Scriptures, of the Holy Fathers and of the renowned Council,
decreed and defined that all men are born infected by original sin; nevertheless, it solemnly declared that it had no intention of including the blessed and immaculate Virgin Mary, the Mother of God, in this decree and in the general extension of its definition. Indeed, considering the times and circumstances, the Fathers of Trent sufficiently intimated by this declaration that the Blessed Virgin
Mary was free from the original stain; and thus they clearly signified that nothing could be reasonably cited from the Sacred Scriptures, from Tradition, or from the authority of the Fathers, which would in any way be opposed to so great a prerogative of the Blessed Virgin.[12] ...
... saying,
“I will put enmities between you and the woman, between your seed and her seed”[13] — taught that by this divine prophecy the merciful Redeemer of mankind, Jesus Christ, the only begotten Son of God, was clearly foretold:
That his most Blessed Mother, the Virgin Mary, was prophetically indicated; and, at the same time, the very enmity of both against the evil one was significantly expressed. Hence,
just as Christ, the Mediator between God and man, assumed human nature, blotted the handwriting of the decree that stood against us, and fastened it triumphantly to the cross,
so the most holy Virgin, united with him by a most intimate and indissoluble bond, was, with him and through him, eternally at enmity with the evil serpent, and most completely triumphed over him, and thus crushed his head with her immaculate foot.[14] ...
(just read that last part again)
... Accordingly, the Fathers have never ceased to call
the Mother of God the lily among thorns, the land entirely intact, the Virgin undefiled, immaculate, ever blessed, and free from all contagion of sin,
she from whom was formed the new Adam,
the flawless, brightest, and most beautiful paradise of innocence, immortality and delights planted by God himself and protected against all the snares of the poisonous serpent, the incorruptible wood that the worm
of sin had never corrupted, the fountain ever clear and sealed with the power of the Holy Spirit, the most holy temple, the treasure of immortality, the one and only daughter of life — not of death — the plant not of anger but of grace, through the singular providence of God growing ever green contrary to the common law, coming as it does from a corrupted and tainted root. ...
... As if these splendid eulogies and tributes were not sufficient, the Fathers
proclaimed with particular and definite statements that when one treats of sin, the holy Virgin Mary is not even to be mentioned;
for to her more grace was given than was necessary to conquer sin completely.[24] ...
... They affirmed that the same Virgin is, and is deservedly, the first and especial work of God, escaping the fiery arrows the the evil one; that she is beautiful by nature and
entirely free from all stain; that at her Immaculate Conception she came into the world all radiant like the dawn. ..." -
