St. Bonaventure on Mary being freed from the woe of concupiscence or the guilt of original sin at the conception of Christ βFinally, the cure of original sin takes place in this way. It is cured as regards guilt, but the temporal punishment remains, as appears in baptized infants; it is cured as regards eternal punishment, but the actual inclination of concupiscence remains; it is cured in the parent, but even so, transmitted to offspring by the very one who was healed in baptism. Its stain is blotted out, but its consequences remain, to be fought against as long as life lasts; for in no human being, assuredly, has concupiscence ever been extinguished by ordinary grace. We say this because in the case of the Blessed Virgin, concupiscence was extinguished by extraordinary grace when she conceived the Son of God.β
The Breviloquium
βSecondly, we must consider that Mary was not only free from the threefold
woe of actual guilt, but also from the threefold woe of original misery, i. e., from the misery of them that are born, from the misery of them that bring forth, and from the misery of them that die. The woe of the misery of being born is the woe of the weakness of concupiscence; the woe of them that bring forth is the woe of the pains of travail; the woe of the dying is the misery of being reduced to dust and ashes. Because of these three woes is it said to the inhabitants of the earth: "Woe, woe, woe to the inhabitants of the earth!" The woe of those who are born is the woe of the fuel of sin which is born in us, by which, according to our original corruption, we are so weak unto good and so prone to evil; so that each one is born with the "fomes peccati," and by this is
weak and wounded, and can truly say with Jeremias: "Woe is me for my destruction, my wound is very grievous. But I said, truly this is my own evil, and I will bear it" (Jer. X, 19.) But alas! not only is there in those that are born weakness and misery, inclining them, when adults, to actual sin; but also the woe of stain and of guilt, bringing them even as little infants under the wrath of God. Therefore the Apostle saith: "All are born children of wrath" (Eph. II, 3.) Oh, how far from this woe of them that are born was the most holy Nativity of Mary, who was not only free from original sin, but also from the fuel of misery, in so far as it leads
to sin, for she was conceived without stain. Because the Nativity of Mary was so far removed from this woe, she is saluted by Ave.β
Mirror of the blessed Virgin Mary, Chapter II
Iβm simply saying itβs possible for Mary to be immaculately conceived and still have some traces of concupiscence left, even if they donβt act up.
