Could Jesus Have Possibly Inherited Original Sin?

Could Jesus Have Possibly Inherited Original Sin? November 11, 2021

Was Mary’s Immaculate Conception Necessary to Prevent Such a Scenario, or Only “Fitting”? Jesus’ Two Natures & Impeccability

This is a rare disagreement with my very good friend and apologetics ally Paul Hoffer. He commented underneath my article, Was Mary Sinless? (vs. 3 Church Fathers & Jason Engwer) [11-9-21]. His words will be in blue.


As I commented on your wonderful earlier article, everything we teach about Mary is really teaching something about Christ. The teaching about Mary’s sinlessness really is about Jesus’ sinlessness. Most Christians today supposedly believe that Jesus was fully human, yet fully divine-what we call the Hypostatic Union. We teach and the Scriptures state that Jesus was like us in all things but sin. Now, Jesus received His human nature from Mary. If Mary was a sinner, Jesus would have received her sin nature. If she was sinless as the Church teaches, then Jesus would not have received a sin nature which confirms what the Scriptures teach.

The ECFs, beginning with St. Irenaeus, taught that just as Jesus was the New Adam, Mary was the New Eve, What Adam injured by his sin, Jesus healed by His sinlessness applied though His death on the cross. What Eve bound by her sin, Mary loosed by her life of sinlessness and bearing Our Lord (which was perfected by the special application of Jesus’ death on the Cross-which is the basis of the Immaculate Conception).. Irenaeus refers to this as the Recapitulation.

This could not have happened if Mary had or retained a sinful nature. Of course, Mary’s role in God’s plan of salvation is purely secondary and dependent on Her Son’s perfect sacrifice, but her role reminds us that all of humanity participates in God’s plan of salvation. WE all have a part to play in making it happen.

Now 21st century science confirms this theological teaching. During pregnancy, children and mothers share cells which remain within both the child and the mother during their entire life. If Mary sinned she would have shared her sinful nature with her Son and if Jesus was sinless, He would have shared His sinless nature with her. God can not abide the presence of sin so how could Our Lord abide the intimate presence of Mary’s sinful nature within Him if her sinful nature was within Him?

Where Protestants go wrong here is their assumption that human beings are totally depraved and that human feelings or weakness are the result of sin. We know this is not true as Jesus got sad, wept, argued, cursed, scolded, got angry, felt anguish, satisfaction, happiness, and expressed love for His family and friends. He had a body that experienced hunger, fatigue, pain, and death. He expressed the full range of human emotions and physicality. In other words, human weakness is not the result of sin; it is the result of us being human.

I believe Church teaching does not hold that Mary had to be sinless, lest Jesus become infected with her sin. The Church teaches that her Immaculate Conception was, rather, “fitting.”

As far as I understand, it’s not possible for Jesus to inherit original sin [i.e., only created, fallen, rebellious human beings were ever subject to that in the first place], since He is God (anymore than it was possible for Him to commit actual sin [impeccability] ). His conception was sui generis, having been from the Holy Spirit.

Sin can never enter God’s nature, and this includes Jesus’ human and divine natures. Therefore, Mary could possibly have been a sinner and still bear Jesus. He wouldn’t and couldn’t inherit sin in any event.

I wrote about this twice:

“Was Mary’s Immaculate Conception Absolutely Necessary?” (12-8-17).

Mary’s Immaculate Conception: Necessary or “Fitting”? (4-26-18)

Hi Dave, I think this is only the second time I have ever disagreed with you (the other about Chief Wahoo).

Of course, you are right to say that Mary did not have to be conceived without sin or to be sinless. I suppose God, being God, could have figured something else out to save us besides coming to us through the Incarnation. I would note that Saints Irenaeus and Athanasius would disagree with that and argue that since sin came into the world through man, our salvation had to come though man as well – any other way would have violated God’s own nature by self-denying His own justice or His mercy.

While it is certainly “fitting”, as in proper, appropriate, just, or right that God chose to save us in this manner, once He chose to save us in this way, it would have been necessary for Mary to be sinless. (Of course, this depends on whether one believes in the doctrine of original sin.) I would point out that the Catechism of the Catholic Church § 490 does use the word necessary as part of its definition of Mary’s maternity and Immaculate Conception:

To become the mother of the Savior, Mary “was enriched by God with gifts appropriate to such a role.” The angel Gabriel at the moment of the annunciation salutes her as “full of grace”. In fact, in order for Mary to be able to give the free assent of her faith to the announcement of her vocation, it was necessary that she be wholly borne by God’s grace.

There is a reason that Mary was conceived without sin. I was focusing on the purpose of her sinlessness-to give Jesus a sinless nature. While you stated that you believed that “Church teaching does not hold that Mary had to be sinless, lest Jesus become infected with her sin” I would suggest that the implications of the Immaculate Conception and the notions of Mary as the New Eve and the New Ark of the Covenant indicate Mary was sinless was so Jesus would inherit a sinless human nature from her.

To argue otherwise would separate the divine Jesus too much from the human Jesus. Jesus was fully man as well as fully divine. If Jesus did not fully inherit His human nature from Mary, then He can not be fully human. And if Jesus truly took His flesh from Mary, then He would have also received the same human nature she had. Since Jesus is like us in all things but sin, if Mary was not preserved from sin through the Immaculate Conception, then Jesus would have inherited her sinful nature as well.

Further as the New Eve, Mary was able to undo what Eve did, which is why Mary is called the Undoer of Knots. She cooperated with God, having that perfect free will that Eve surrendered in sin.

Similarly, the analogy that the early fathers made to Mary being the Ark of the Covenant also was being made because just as the Ark of the Covenant had to be spotless without any defilement do the Glory/Presence of God could dwell there. The divine nature of Jesus Christ demanded that His mother be kept from the pollution of sin so that He, the Glory/Presence of God, could dwell within her.

Mary, as the New Eve, protects the dignity of Jesus’ human nature while Mary, as the Ark of the Covenant, protects the dignity of His divine nature.

Again, to emphasize the point I made that Marian doctrines all point to Christological doctrines, if God had simply created Jesus alone without sin in a sinful Mary’s womb, could we say He was fully human? To be fully human is to share the very flesh of one’s mother. That is the whole point of the Incarnation and why we say in the Creed that Jesus was born of the Virgin Mary. Unless you are a Docetist, Nestorian or some Protestant variation thereof, Chalcedonian Christianity teaches that Jesus inherits His human nature from his mother, not an abstract human nature separated from his mother.

Since God chose the Incarnation as the fitting means of our salvation, it then became “necessary” that Mary be sinless so that Jesus; human nature could be sinless. It was necessary that Jesus had to inherit her human nature in order to save humanity through His Incarnation. Or as Saint Athanasius puts it in his opus “On the Incarnation,” what is not assumed is not saved. The Immaculate Conception and Mary’s subsequent sinlessness were the means that God chose to make sure that Jesus did not inherit a sinful human nature, but a sinless perfect one.

Based on the above, Mary, in one sense, is a sinner because she too needed a savior. However if Mary bore Jesus, she could not have been a sinner in a different sense of the word. She gave Him her sinless human nature which was sinless only because of the special application of the grace of Her Son’s sacrifice on the cross. Jesus did not inherit a sinful human nature from Mary only because God chose to ensure that she did not have one through the Immaculate Conception. Thus, Mary’s sinlessness was a necessary part of God’s economy of salvation if God is to be both just and merciful.

It’s true we rarely disagree! I wrote in the second paper I linked to above:


Blessed Pope Pius IX, in his 1854 declaration on the Immaculate Conception (Ineffabilis Deus) wrote:

For it was certainly not fitting that this vessel of election should be wounded by the common injuries, since she, differing so much from the others, had only nature in common with them, not sin. In fact, it was quite fitting that, as the Only-Begotten has a Father in heaven, whom the Seraphim extol as thrice holy, so he should have a Mother on earth who would never be without the splendor of holiness.

In his treatise “On the Virginal Conception,” St. Anselm expounded the principle on which the doctrine rests in the fallowing words: “It was fitting that the conception of that man (Christ) should be accomplished from a most pure mother. For it was fitting that that Virgin should be resplendent with such a purity, . . .”

The Catechism teaches the same:

#722 The Holy Spirit prepared Mary by his grace. It was fitting that the mother of him in whom “the whole fullness of deity dwells bodily” should herself be “full of grace.” She was, by sheer grace, conceived without sin as the most humble of creatures, the most capable of welcoming the inexpressible gift of the Almighty. . . .”

Facebook friend René Albert commented: “I agree that it’s ‘fitting’. But if we consider how a bad tree cannot produce good fruit (Matt 7:18), wouldn’t Jesus have inherited Original Sin through Mary?”

I reply:

It’s not possible because:

1) Jesus is God, and God cannot sin (He is impeccable), nor can He rebel against Himself (which is what caused original sin). This remains so whether Mary in fact sinned or not.

2) Jesus was not part of created humankind, which rebelled against God, bringing about original sin.

3) Jesus was not the offspring of a human father and mother. His was a miraculous conception through the Holy Spirit (virgin birth). This also bypasses any notion of “inherited sin” as a possibility in His case.

This gets into the doctrine of Jesus’ Two Natures and His impeccability. Fernand Prat, S. J. wrote: “Jesus, being by his nature impeccable, cannot be made a sinner by his contact with sinners, . . .” (The Theology of St. Paul, Westminster, Maryland: Newman Bookshop, 1952, Vol. II, 205).

Ludwig Ott (Fundamentals of Catholic Dogma, translated by Patrick Lynch, edited in English by James Canon Bastible, Rockford, Illinois: TAN Books and Publishers, Inc., fourth edition, 1960, p. 169) says that Christ “could not sin” and based that on the Hypostatic Union: “His human actions are actions of a Divine Person.” He adds: “From the Hypostatic Union there arises a physical impossibility of sinning and from the Beatific Vision a moral impossibility . . .” Ott classifies this as a sententia fidei proxima doctrine (regarded generally by theologians as a truth of revelation). He adds:

The Fifth General Council of Constantinople (553) condemned the teaching of Theodor of Mopsuestia, which asserted that Christ only became completely impeccable after the resurrection (Denzinger 224). It follows from this that He was already impeccable.

Likewise, Fr. John A. Hardon, S. J., in his Modern Catholic Dictionary (Garden City, New York: Doubleday & Co., 1980, “Impeccability of Christ,” 269), states that this means the “absolute impossibility of Christ committing any sin.”

The bishops have rendered their authoritative opinion as well:

Review of Fr. McBrien’s Catholicism, National Council of Catholic Bishops’ Committee on Doctrine, April 9, 1996:

A. Examples of Inaccurate or Misleading Statements

1) The Impeccability of Jesus Christ

Catholicism insists that it is possible to hold the faith of the church while maintaining that Jesus Christ could have sinned. “It is not that Jesus Christ was absolutely incapable of sin, but rather that he was able not to sin and, in fact, did not sin” ( p. 547). The book argues that “both views – the one favoring impeccability and the one that does not – are within the range of Catholic orthodoxy” (p. 547). This position, however, cannot be reconciled with the Christology of the councils.

[Footnote 2: In the anathemas against the Three Chapters, the Second Council of Constantinople (553) condemned the opinion attributed to Theodore of Mopsuestia that Jesus attained impeccability only with the resurrection (Denzinger-Schonmetzer, Enchiridion Symbolorum 434).]

In two natures, Jesus Christ is only one hypostasis (or person), the hypostasis of the Word. With Christ there is no possible subject of the verb to sin. There are indeed two wills in Christ, but only one person, one subject. The contention that Jesus could have sinned, if followed to its logical conclusion, inevitably implies a Nestorian or an adoptionist Christology, though it must be said that Catholicism does not draw such extreme conclusions.

Fr. William Most, Comments on Richard McBrien, Catholicism, 3rd Edition:

The sinlessness of Jesus

He admits that Jesus did not sin, yet He was capable of sinning (p. 547). He was not immune to sexual desires (pp. 562-63).

McBrien grants that the Church does teach, as does the NT, that Jesus was without sin. But he has trouble about the impeccability, inability to sin, of Jesus. He quotes the Third Council of Constantinople (381) saying that His human will is “compliant, it does not resist or oppose, but rather submits to the divine and almighty will.” We grant this does not explicitly state impeccability. McBrien continues saying it seems better to conclude that it is the “clear and constant belief and teaching of the Church that Jesus Christ was perfect in his humanity.” He seems then to think of the Council of Chalcedon which he cited earlier saying He was “like us in every respect apart from sin,” and the similar statement of Hebrews.

So McBrien says the NT does not go in for theological speculation. And the official texts do not formally teach impeccability. This is true.

Nor are there many patristic texts on impeccability, not enough to satisfy the requirement of being practically unanimous. St. Cyril of Alexandria wrote (R 2141): “they are stupid, who affirm, I do not know how, that even Christ could have sinned.” St. John Damascene is more helpful (R 2386): “Because there is one person of Christ, and in Christ, there is one who wills through each nature: as God, in approving, and as man, being made obedient.” (Cf. also St. Athanasius in R 798).

But we can sharpen this up a bit: We do not say it is nature that sins, but a person sins. But in Christ there was only one Person, even though two natures. If He had sinned, the sin would have been attributed to the one Person, a Divine Person. Which of course is impossible.

Finally we mention Canon 12 of the second General Council of Constantinople, in 553 (DS 434) which spoke of Theodore of Mopsuestia as “impious” because he spoke of Christ as “suffering from passions of soul and desires of the flesh, and gradually going away from the worse things, and so becoming better by advancing in works . . . merited divine sonship . . .”

The revised version of Ott, Fundamentals of Catholic Dogma (2018) deals with the impeccability of Jesus on pp. 183-185. The statement: “Christ was free from all sin, from original sin as well as from all personal sin” is De Fide dogma.

Ott, after citing DH 1347, states:

As original sin is propagated by natural generation, and since Christ entered life in a supernatural manner through conception, by the Holy Spirit . . . it follows that He was not subject to the general law of original sin.

From this it follows that Mary need not have been necessarily immaculate in order for Jesus to be free from original sin. He would have been in either case. We believe she was immaculate, of course, but because it was “fitting” rather than necessary for the sake of Jesus. Ott continues:

The Fathers and the theologians infer Christ’s freedom from original sin from the Hypostatic Union, which being a most intimate connection with God, excludes the condition of separation from God implied by original sin.

You cite the Catechism (#490) and state that it “does use the word necessary as part of its definition of Mary’s maternity and Immaculate Conception.” But I think you are misreading that. It uses the word “appropriate” which is a synonym of “fitting.” When it refers to something as “necessary” it is “for Mary to be able to give the free assent of her faith to the announcement of her vocation.” So it had to do with her fiat and undoing of Eve’s “no”; nothing to do with some supposed necessity of keeping Jesus from inheriting original sin.

Ineffabilis Deus: the proclamation of the Immaculate Conception, uses the word “fitting” three times. “Necessary” appears once, but again has nothing to do with the topic at hand:

[T]he 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.

“Original sin” appears ten times in the document, but never is it in conjunction with this notion that Our Lady’s preservation from it was necessary in order to conceive a sinless, God-Man Jesus Christ. Certainly, if this were true, then the infallible ex cathedra proclamation making the dogma binding upon all Catholics would spell it out clearly, as the most important reason for the dogma and the reality it describes to exist in the first place.

Since it doesn’t do so, we can reasonably conclude that it is a non-issue (Christ’s Two Natures and impeccability making it so), having nothing to do with the dogma of the Immaculate Conception of Mary. In other words, this solemn proclamation would be the place of all places, to explain this supposed “necessity” if in fact it existed. It would be the central reason for it: yet another Christocentric emphasis. But it’s utterly absent.

The argument basically is this All Mariology is actually Christology. In a nutshell, I contend that there are implications of the dogma of the Immaculate Conception that adds to and enriches our understanding of our Chalcedonian Dyothelite Christology. The Incarnation means the Logos/Word was made flesh, meaning that the Divine Person of the Son took on a human body, a human nature, and a human will. When Mary conceived Jesus in her womb by the power of the Holy Spirit, the question becomes what did she contribute to the Incarnation? Did she only provide Him a Jesus suit that God put on, or did she give Him something more than that? If she did not provide Him His human nature or His human will, where did they come from? And how is it if she did give Christ His human nature and human will, His nature was not sinful and that His human would be fully conformable with His divine will?
if Mary was a sinner, it is a lot harder to refute a heretic’s argument that Jesus did not inherit her sinful nature as well if we are going to argue that Jesus was fully human. On the other hand, the Immaculate Conception resolves that because the implication of Mary being preserved from sin from the moment of her conception means she would have given her Son a human nature that also was not sinful.
The Orthodox do not have the same understanding of original sin that we Catholics do nor do they believe in the Immaculate Conception. Some Orthodox even question whether Mary sinned.
I will flesh this out (no pun intended) by next week.

I asked my friend, Catholic theologian Dr. Robert Fastiggi, to offer his opinion on this dispute. Here is his answer, sent to my email:

Reply on the necessity or fittingness of the Immaculate Conception

I read through your exchange with Paul Hoffer on whether it was necessary or fitting for Mary to be conceived without original sin. I think you both have good insights. Many of the Fathers and medieval theologians believed Mary was free from all sin at least by the time of the Annunciation. This is the position of most of the Eastern Orthodox today. It’s as if, by intuition, they sense that our Lord could not assume a human nature from a mother who is sinful. Is this a matter of necessity or fittingness? We need to understand, of course, that we must be very careful in stating that it’s absolutely necessary for God to do this or that. It was not absolutely necessary that God create, yet it was it in accordance with his goodness that He would create (cf. CCC, 296).

St. Thomas Aquinas, in the ST, p. III, q. 1 a. 2 raises the question whether it was necessary (necessarium) that the Word become incarnate for the reparation of the human race. He argues that something can be considered necessary in two ways: 1) in the absolute sense when the end cannot be achieved without it; and 2) in a secondary sense when the end is attained in a better and more convenient way, as a horse is necessary for a journey. The Incarnation was not absolutely necessary in the first sense because God, in his omnipotence, could have redeemed the human race in many ways; but it was necessary in the secondary sense. Aquinas then proceeds to give multiple reasons why the Incarnation was necessary in the secondary sense of congruity.

With regard to the Immaculate Conception of Mary a similar mode of analysis is in order. In terms of absolute necessity, the Word could have received a sinless human nature from a Mother who had been purified rather than preserved from original sin. In terms of secondary necessity, it seems altogether fitting that the Word would receive his human nature from a mother who was never under sin. As Pope Leo the Great says: “From the Mother of the Lord, nature, not guilt was assumed” (DH, 294). I think Paul Hoffer might do better to argue that the Immaculate Conception is necessary in the secondary sense of congruity. This is similar to the argument of Bl. John Duns Scotus: God could preserve Mary from original sin; it was fitting that He do so; therefore, He did it (potuit, decuit; ergo fecit).

We could also follow the reasoning of St. Louis de Montfort who, in True Devotion, 14, states that God never had any absolute need of Mary. In True Devotion, 15, however, St. Louis states that since God has decided to begin and accomplish his greatest works through Mary, He will not change his plans.  This could be put in terms of God’s absolute will and his ordained will. In terms of his absolute will, the Immaculate Conception was not necessary. In terms of his ordained will, it was.

The question is speculative. I think it’s sufficient simply to affirm the fittingness of Mary’s Immaculate Conception. Because this privilege is fitting and congruous to God's ordained plan for redemption, it has a type of necessity to it. But this is a necessity in a secondary and not in an absolute sense.

I hope these thoughts are of some help.

If Paul replies further, I will include that here. I concur with Dr. Fastiggi and have nothing more to add.

Summary: Was Mary’s Immaculate Conception absolutely necessary in order for Jesus to not contract original sin at His conception? I maintain that the Church says “NO”.
