Thanks, Vico. I was struggling to come up with a way to explain it to Mardukm, but that simple definition actually does it, at least to some degree (keeping in mind that this is not a doctrine I’m invested in, and I find it unnecessary at best). Ineffabilis Deus makes a big deal out of differentiating between ‘the first instance of conception and the second’, without really explaining what either of those actually are. So, if taken in concert with the quote from Pope Alexander VII, the ‘first instance’ of conception must include the infusion of the soul into the body (as per the quote), but not the physical conception of St. Mary by Joachim and Anna (as per Mardukm’s objection). The trouble with that, of course, is that conception does refer to physical conception (even in Catholic sources, as you’ve shown), regardless of whether or not there are additional ideas about the infusion of the soul in the process (which, I have to wonder, if when that happens is not the point, why is this part of it? The quote from Pope Alexander VII talks about “the first instant”, and the rest of the paragraph talks about “the first and second” conceptions, so clearly this is about solving some kind of temporal problem or laying out some kind of temporal sequence). It seems like another instance where words mean whatever Rome wants them to mean, and if you object to that you just don’t “get” it. Well, fine. I don’t get it. That much is clear. I don’t understand why this is necessary in the first place, after all.
The choice of words is not arbitrary but is in response to the terms used throughout the ages by the Doctors of the Church.
From 1854 we see the reason for the definition at that time:“Accordingly, from ancient times the bishops of the Church, ecclesiastics, religious orders, and even emperors and kings, have earnestly petitioned this Apostolic See to define a dogma of the Catholic Faith the Immaculate Conception of the most holy Mother of God. These petitions were renewed in these our own times; they were especially brought to the attention of Gregory XVI, our predecessor of happy memory, and to ourselves, not only by bishops, but by the secular clergy and religious orders, by sovereign rulers and by the faithful.”
The basic idea is that Eve was free from corruption (this means more than virginity) when she was addressed by the serpent. By implication it seems to follow that Mary too was free from all corruption when she was greeted by the angel.
In patristic times, St. Augustine shows the belief in the sinlessness of the Virgin Mary.
In the early Church in the west, St. Augustine wrote against Pelagius (who reckoned a number of persons were presumably sinless in support that human nature was not corrupted by original sin). St. Augustine said these persons were not sinless “except the holy Virgin Mary, of whom, for the honor of the Lord, I wish to raise no question when discussing sin.”

The Second Council of Orange, 529 A.D., condemned Semi-Pelagianism, that is, that one can make the first move towards God without grace. CANON 6. If anyone says that God has mercy upon us when, apart from his grace, we believe, will, desire, strive, labor, pray, watch, study, seek, ask, or knock, but does not confess that it is by the infusion and inspiration of the Holy Spirit within us that we have the faith, the will, or the strength to do all these things as we ought; or if anyone makes the assistance of grace depend on the humility or obedience of man and does not agree that it is a gift of grace itself that we are obedient and humble, he contradicts the Apostle who says, “What have you that you did not receive?” (1 Cor. 4:7), and, “But by the grace of God I am what I am” (1 Cor. 15:10).
Then in the Middle Ages:
- Sanctifying grace was not yet a developed idea. The original sin was thought of as a positive element transmitted through the marital act, rather than a lack of sanctifying grace.
- It was not clear how an Immaculate Conception would be congruent with universal redemption though Christ.
- Duns Scotus provided an way with the concept of preservation from (stain of) original sin, and remarked that “no one who is able to honor his mother would fail to do so”.
- Sixtus IV in 1477 made the celebration universal in the Latin Church. (Bull Cum praeclesa, 1476).
We see that St. Thomas Aquinas failed to understand that the grace of redemption might be of preservation and prevention simultaneously. According to St. Thomas, the human body is animated successively in vegetative, sensitive, and rational soul, such that the body of the Blessed Virgin Mary, descended from Adam materially and seminally, contracted the bodily defects which are conveyed by seminal generation, and are the results of the privation of original justice. Redemption could occur only once there is a rational soul, the third step. The dogma has decided against that position.
The dogma clarifies the issue, especially needed in light of the great respect for St. Thomas Aquinas.
The dogma counters Semi-Pelagianism because the Blessed Virgin Mary made her election only
with God given grace. Semi-Pelagianism arose
again later at the Reformation.
