On this day, March 7, in the year 1274, seven hundred and thirty six years ago, St. Thomas Aquinas departed from this life, and thus today is his traditional feast day.¹ Last year, on this day, I began a series of posts intending to show how St. Thomas’s theology helps explain the soteriology set forth in the decrees and canons of the Council of Trent. This post is a continuation of that series.  Having laid out what St. Thomas wrote about original sin,  here I examine and explain what the Fifth Session of the Council of Trent taught concerning original sin.

Temptation, Fall, and Expulsion
Brothers Limbourg (1411-1416)

When a Catholic monk named Martin Luther posted ninety-five theses on the door of the Castle Church in Wittenberg in October of 1517, he initiated a controversy that eventually led not only to his excommunication on January 3, 1521, but to the subsequent separation of Protestants from the Catholic Church. During the following two decades the Church attempted to effect a reconciliation with Protestants. These efforts culminated in Pope Paul III convoking an ecumenical council in 1542, the nineteenth ecumenical council in the history of the Church.² This council met in the city of Trent, and had its first session in 1545. The purpose of the Council was two-fold: to extirpate various heresies that had arisen, and to reform the morals among the clergy and the lay faithful.³

The First Session formally opened the Council. The Second Session set forward the manner in which the bishops should conduct themselves during the Council. The Third Session expressed the Creed of the Church. The Fourth Session addressed the canon of Scripture. The Fifth Session addressed the doctrine of original sin. And the Sixth Session addressed the doctrine of justification.

It was not by accident that the Council addressed the doctrine of original sin before taking up the doctrine of justification. The doctrine of justification depends in part on the doctrine of original sin, as I shall show below. So in order rightly to understand the Council’s teaching on justification, one must first understand its teaching on original sin. In previous posts in this series, I presented and explained St. Thomas’s theology of original sin. (See “Aquinas and Trent: Part 2,” in which I explain the essence of original sin, according to St. Thomas, and “Aquinas and Trent: Part 3,” in which I explain the effect of original sin, according to St. Thomas.) I will not repeat here what I have said there; and what I say here presupposes that the reader has read at least those two posts in this series.

Why is the Council of Trent relevant to the reconciliation of Protestants and Catholics? Shouldn’t we just put the past behind us, and move forward? The reason why the Council of Trent remains relevant is that the canons of the Council of Trent are infallible, so the Church has no authority to overturn them. Whatever was declared heretical at Trent will remain heretical until Christ returns in the clouds in glory. The authority of the canons does not depend on whether those claims were in fact affirmed by any person. Nor does it depend on the bishops’ degree of understanding of the Protestants’ theological positions. But the canons condemn only the claims stated in the canons; they do not condemn unstated positions that may have been held by Protestants. Doesn’t the infallibility of the canons of Trent make ecumenical dialogue pointless? Not at all. To understand why, see my post titled “Two Ecumenicisms.” Protestants and Catholics can be reconciled only by coming to the truth concerning their separation in the sixteenth century. And that requires coming to terms with the Council of Trent. Protestants can no more reject the Council of Trent on the basis of their own interpretation of Scripture than any other heresy in the history of the Church could justifiably reject the teaching of an ecumenical council on the basis of its own interpretation of Scripture.

The Fifth Session: The Decree Concerning Original Sin

The Decree of the Fifth Session begins with an introductory paragraph:

That our Catholic faith, without which it is impossible to please God,⁴ may, after the destruction of errors, remain integral and spotless in its purity, and that the Christian people may not be carried about with every wind of doctrine,⁵ since that old serpent,⁶ the everlasting enemy of the human race, has, among the many evils with which the Church of God is in our times disturbed, stirred up also not only new but also old dissensions concerning original sin and its remedy, the holy, ecumenical and general Council of Trent, lawfully assembled in the Holy Ghost, the same three legates of the Apostolic See presiding, wishing now to reclaim the erring and to strengthen the wavering, and following the testimonies of the Holy Scriptures, of the holy Fathers, of the most approved councils, as well as the judgment and unanimity of the Church herself, ordains, confesses and declares these things concerning original sin:

Here the Tridentine Fathers affirm that the Church’s faith, without which it is impossible to please God, includes things concerning original sin and its remedy.  In other words, the gospel includes a teaching on original sin. The bishops explain that they are addressing this subject in response to what they believe to be the work of the devil in stirring up dissensions new and old concerning the doctrine of original sin and its remedy. They state again that they are assembled as a “general and ecumenical” council, in accordance with the laws of the Church, and presided over by legates of the Apostolic See (i.e. Rome). For this reason they are assured of the presence and guidance of the Holy Spirit, who guides the Church into all truth (John 16:13), most assuredly when her bishops are assembled in ecumenical council.⁷ The Council states its intention to bring back those sheep that are erring, and to strengthen those sheep that are wavering. Lastly, the bishops affirm that what they are teaching regarding original sin follows both the testimony of the Holy Scriptures, and that of the unanimity of the Church, not only at that time but throughout the 1500 year history of the Church preceding the Council.

Next the Council in five paragraphs addresses five errors pertaining to original sin. I will examine each of these five paragraphs in turn.

I. The Error of Denying Original Sin

In the first paragraph the Council declares:

1. If anyone does not confess that the first man, Adam, when he transgressed the commandment of God in paradise, immediately lost the holiness and justice in which he had been constituted, and through the offense of that prevarication incurred the wrath and indignation of God, and thus death with which God had previously threatened him,⁸ and, together with death, captivity under his power who thenceforth had the empire of death, that is to say, the devil,⁹ and that the entire Adam through that offense of prevarication was changed in body and soul for the worse,¹⁰ let him be anathema.

In this first paragraph, the Council is condemning the error of denying that Adam, by his sin, lost the original holiness and righteous that God had given him. According to the Council, when Adam transgressed God’s commandment, the following five things happened: (1) he lost the holiness and justice in which he had been constituted, (2) he incurred the wrath and indignation of God, (3) he incurred the death with which God had previously threatened him, (4) he incurred captivity under the power of the devil who from that time on had the empire of death, and (5) he was changed for the worse both in body and soul. The statement about the change in “body and soul” is a reaffirmation of the first canon of the Second Council of Orange (529 AD), which canon was intended to refute the error of those who taught that not the soul but only the body was damaged by Adam’s sin.

The loss of the original holiness and justice in which man had been constituted refers to the loss of what St. Thomas treats as the third good of human nature, explained here and here in previous posts in this series. There too I laid out his explanation for death as the result of sin, and what it means to be “changed for the worse” both in body and in soul. The wrath and indignation of God I discussed in my post on St. Thomas’s doctrine on the Passion of Christ. St. Thomas discusses man’s captivity under the power of the devil in Summa Theologica III Q.49 a.2.

The most important thing to understand in this first paragraph, with respect to reconciling Protestants and the Catholic Church, is what the Council is saying when it teaches that by his sin Adam lost the holiness and justice in which he had been constituted. The holiness and justice to which the Council refers are due to the presence of sanctifying grace and agape in Adam’s soul. Adam was holy because he had sanctifying grace in his soul, that is, he was a participant in the divine nature (2 Peter 1:4), and enjoyed the indwelling of the Trinity.¹¹ And he was just (or righteous) because he had agape, i.e. love for God as Father. This original holiness and justice was not something Adam produced by his own nature. Nor were they part of the essence of his human nature; otherwise, in losing them he would have ceased to be human.

Why is this important for Protestant-Catholic reconciliation? Many Protestants believe that grace is only for the forgiveness of sins, and hence only something Adam and Eve received after they sinned. For this reason they tend to treat salvation prior to the Fall as by human-works-apart-from-grace, and salvation after the Fall as by grace-apart-from-human-works. But the notion that Adam and Eve, apart from grace, could have merited the Beatific Vision, is a form of Pelagianism.¹² Only God has His [divine] inner life and the perfect happiness of seeing God, by His very nature. Man could have the Beatific Vision by his nature without grace only if he were God. But man is not God; man is a creature. Therefore, in order to attain the Beatific Vision, which is supernatural end [i.e. an end above the reach of man's nature as such], man needs grace. In order for man to enter into heaven, i.e. into the perfect beatitude of the inner Life of the Trinity, God must give to man a participation in this inner Life; man must receive the gift of grace from God.

The Second Council of Orange (AD 529), which was primarily responding to Pelagianism, declared:

“Even if human nature remained in that integrity in which it was formed, it would in no way save itself without the help of its Creator.” (Can. 19)

Notice that “save” is not only from punishment, because human nature would remain in that integrity in which it was formed, only if Adam had not sinned. And where there is no sin, there is no punishment. But yet, according to Orange contra the Pelagians, even a sinless Adam and Eve would have needed divine help in order to be “saved.” In other words, they would have needed grace, to attain heaven, even if they had not sinned. St. Thomas concurs, writing:

But man’s perfect Happiness, as stated above (Question 3, Article 8), consists in the vision of the Divine Essence. Now the vision of God’s Essence surpasses the nature not only of man, but also of every creature, as was shown in the I, 12, 4. For the natural knowledge of every creature is in keeping with the mode of his substance: thus it is said of the intelligence (De Causis; Prop. viii) that “it knows things that are above it, and things that are below it, according to the mode of its substance.” But every knowledge that is according to the mode of created substance, falls short of the vision of the Divine Essence, which infinitely surpasses all created substance. Consequently neither man, nor any creature, can attain final Happiness by his natural powers.¹³

And that is why, in Catholic theology, Adam and Eve were given grace by God, prior to their Fall. It was by grace that they were able to walk with God in the cool of the day. No one can have friendship with God apart from grace, because no one can have friendship with God without agape, and no one can have agape without grace. Agape is supernatural;¹⁴ it is poured out into our hearts by the Holy Spirit.¹⁵ Man does not cease to be man if he loses agape. Hence, agape is not an essential component of our human essence or human nature. If agape were had by nature, then man without agape would be a contradiction in terms. God did not have to walk with Adam in the cool of the day. He did not have to form a friendship with man. He did this gratuitously, as a gift. This divine friendship with man as Father to son was a superadded gift of grace, not something man has by his nature as man.¹⁶

Yet, when we recognize that grace was necessary prior to the Fall, in order for Adam and Eve to have merited the Beatific Vision, then we no longer have a principled basis for excluding works done in grace from being meritorious toward the Beatific Vision under the New Covenant. And the role of works under grace is explicitly one of the points of disagreement between Protestants and the Catholic Church. It is also addressed in the Sixth Session of the Council of Trent. So here we see that rightly understanding the reasons for a doctrine taught in the Sixth Session requires understanding what was taught in the Fifth Session.

II. The Error of Denying that Adam’s Sin Deprived His Posterity of Original Holiness and Justice

In this second paragraph, the Council declares:

2. If anyone asserts that the transgression of Adam injured him alone and not his posterity,¹⁷ and that the holiness and justice which he received from God, which he lost, he lost for himself alone and not for us also; or that he, being defiled by the sin of disobedience, has transfused only death and the pains of the body into the whole human race, but not sin also, which is the death of the soul, let him be anathema, since he contradicts the Apostle who says: By one man sin entered into the world and by sin death; and so death passed upon all men, in whom all have sinned.¹⁸

In this second paragraph, the Council is condemning the error of denying that Adam’s sin deprived his posterity of original holiness and justice. The Council here affirms three things: (1) Adam’s transgression did not only injure himself, but also his posterity, (2) Adam’s transgression lost not only for himself but also for us his posterity the original holiness and justice that he had been given by God, (3) Adam’s transgression transfused to us not only bodily pains and bodily death, but also transfused sin, which is the death of the soul, into the whole human race. Adam was supposed to be propagate sanctifying grace to his offspring. In this way, the sexual act would have been a means of grace for the child conceived. But, by his sin, Adam passed on to his offspring the privation of sanctifying grace and agape, and hence the privation of holiness, righteousness. And that is precisely what original sin is, the privation of original righteousness. That is what it means for the soul to be dead, not for it to lack natural life, but for it to lack divine life, i.e. sanctifying grace and agape.

In addition,  because Adam lost the original righteous he had been given, he also lost the preternatural gifts (integrity of powers of the soul, infused knowledge, impassibility, and immortality)  he had enjoyed, and therefore he passed on concupiscence, ignorance, suffering, and death to his offspring. Those who claim that grace is only needed for forgiveness of sin, falsely conclude from the fact that the infant has committed no actual sin that the infant does not yet need grace for salvation, and therefore does not yet need baptism. This again, is Pelagianism, because it denies that sanctifying grace is absolutely needed to attain to heaven.  Similarly, those who mistake concupiscence (i.e. disordered appetites) for original sin find that such disordered appetites remain after baptism, and falsely conclude that baptism is not the remedy for original sin. But the fundamental problem of man, is not that he has disordered lower appetites, but that he lacks sanctifying grace, and hence lacks agape.  That’s what original sin is; the privation of sanctifying grace and agape. And for that, the remedy is baptism, as we will see in the next paragraph.

III. Errors Regarding the Remedy for Original Sin

3. If anyone asserts that this sin of Adam, which in its origin is one, and by propagation, not by imitation, transfused into all, which is in each one as something that is his own, is taken away either by the forces of human nature or by a remedy other than the merit of the one mediator, our Lord Jesus Christ,¹⁹ who has reconciled us to God in his own blood, made unto us justice, sanctification and redemption;²⁰ or if he denies that that merit of Jesus Christ is applied both to adults and to infants by the sacrament of baptism rightly administered in the form of the Church, let him be anathema; for there is no other name under heaven given to men, whereby we must be saved.²¹ Whence that declaration: Behold the Lamb of God, behold him who taketh away the sins of the world;²² and that other: As many of you as have been baptized, have put on Christ.²³

In this third paragraph, the Council condemns two errors. The first error is to claim that the remedy for original sin is something other than the merit of Jesus Christ, the Second Adam. The second error is to deny that adults and children receive Christ’s merit through the sacrament of baptism. Positively, in this paragraph the Council is teaching three things: (1) the sin of Adam that is transfused into all his posterity by propagation, not by imitation, is in each of us as something that is our own, (2) this sin [of Adam] in each of us is not taken away either by the forces of human nature or by any remedy other than the merit of the one mediator, our Lord Jesus Christ, who has reconciled us to God in His own blood, and (3) the grace that Christ merited in His Passion, by which the sin [of Adam] in us is removed, is applied both to adults and to infants by the sacrament of baptism rightly administered in the form of the Church.²⁴

This paragraph is relevant to the reconciliation of Protestants with the Catholic Church because many Protestants deny that baptism is anything more than a sign or symbol, not recognizing baptism as the sacrament Christ established as the means through which we receive the sanctifying grace He merited for us in His Passion. For these Protestants, to be forgiven only requires believing the message about Christ and trusting in Him; baptism is something one does subsequently in obedience to Christ’s command. But the Church has always believed and taught that it is in baptism that we are joined to Christ, and receive the grace He merited for us in His Passion. This is what we say in the Creed: “one baptism for the forgiveness of sins.” And the efficacy of baptism as the sacrament of salvation is taught unanimously by the Church Fathers.²⁵ Of course faith does come by hearing. But in Catholic doctrine the sanctifying grace through which we have the virtues of faith, hope and agape, comes to us through the sacrament of baptism. We first come to believe the good news, and have love for Christ, by hearing the gospel.²⁶ But in the sacrament of baptism, faith, hope and agape are deepened; they are made to be firmly planted dispositions in our soul. In baptism they become theological virtues.²⁷ In baptism we are ingrafted into Christ (cf. Rom 6), and by becoming firmly rooted dispositions faith, hope, and agape become part of who we are, not just acts we do.²⁸

IV. The Error of Denying that Infants Need Baptism as a Remedy for Original Sin

4. If anyone denies that infants, newly born from their mothers’ wombs, are to be baptized, even though they be born of baptized parents, or says that they are indeed baptized for the remission of sins,²⁹ but that they derive nothing of original sin from Adam which must be expiated by the laver of regeneration for the attainment of eternal life, whence it follows that in them the form of baptism for the remission of sins is to be understood not as true but as false, let him be anathema, for what the Apostle has said, by one man sin entered into the world, and by sin death, and so death passed upon all men, in whom all have sinned,³⁰ is not to be understood otherwise than as the Catholic Church has everywhere and always understood it.

For in virtue of this rule of faith handed down from the apostles, even infants who could not as yet commit any sin of themselves, are for this reason truly baptized for the remission of sins, in order that in them what they contracted by generation may be washed away by regeneration.³¹ For, unless a man be born again of water and the Holy Ghost, he cannot enter into the kingdom of heaven.³²

In this fourth paragraph the Council condemns two errors. The first is the error of denying that infants are to be baptized. The second is the error of denying that infants should be baptized for the remission of original sin. Positively, the Council here teaches four things: (1) Newly born infants are to be baptized, even if born of baptized parents, (2) Newly born infants are to be baptized for the expiation of original sin from Adam for the attainment of eternal life, (3) The words of the Apostle Paul in Romans 5:12 should not be understood otherwise than as the Catholic Church has everywhere and always understood them, and (4) According to this rule of faith [i.e. how Romans 5:12 has everywhere and always been understood by the Church] handed down from the apostles, even infants who could not as yet commit any sin of themselves, are (like adults) truly baptized for the remission of sins in order that what they contracted by generation [i.e. original sin] may be washed away by regeneration.

The primary problem for the newborn infant, prior to baptism, is not that he is not yet a member of the covenant family by a public sign or seal. The primary problem for the newborn infant is that he does not have sanctifying grace and agape, and thus does not have original righteousness or holiness, and thus is not in friendship with God. And that problem infinitely outweighs all other problems because what is at stake is eternal life and eternal separation from God. Doing a baby-dedication is a pious act, but Christ never instituted ‘dedication’ as a means by which anyone would receive grace; He instituted baptism. We know, of course, that God is capable of acting in extraordinary ways to give grace to whomever He wills at whatever times He wills. It is surely not beyond His power to do so. But we must not treat the possibility of the extraordinary as an excuse not to pursue with all our effort the ordinary means God has established through Christ by which adults, children, and infants are given the grace that translates them from death to life, from enemies of God to His friends.

V. Errors Regarding the Removal of Sin Through Baptism

5. If anyone denies that by the grace of our Lord Jesus Christ which is conferred in baptism, the guilt of original sin is remitted, or says that the whole of that which belongs to the essence of sin is not taken away, but says that it is only canceled or not imputed, let him be anathema. For in those who are born again God hates nothing, because there is no condemnation to those who are truly buried together with Christ by baptism unto death,³³ who walk not according to the flesh,³⁴ but, putting off the old man and putting on the new one who is created according to God,³⁵ are made innocent, immaculate, pure, guiltless and beloved of God, heirs indeed of God, joint heirs with Christ;³⁶ so that there is nothing whatever to hinder their entrance into heaven. But this holy council perceives and confesses that in the one baptized there remains concupiscence or an inclination to sin, which, since it is left for us to wrestle with, cannot injure those who do not acquiesce but resist manfully by the grace of Jesus Christ; indeed, he who shall have striven lawfully shall be crowned.³⁷ This concupiscence, which the Apostle sometimes calls sin,³⁸ the holy council declares the Catholic Church has never understood to be called sin in the sense that it is truly and properly sin in those born again, but in the sense that it is of sin and inclines to sin. But if anyone is of the contrary opinion, let him be anathema. This holy council declares, however, that it is not its intention to include in this decree, which deals with original sin, the blessed and immaculate Virgin Mary, the mother of God, but that the constitutions of Pope Sixtus IV, of happy memory, are to be observed under the penalties contained in those constitutions, which it renews.³⁹

In this fifth paragraph the Council first condemns two errors. The first is the error of denying that by the grace of Christ which is conferred at baptism, the guilt of original sin is remitted. The second is the error of claiming that the whole of that which belongs to the essence of sin is not taken away, but that the [debt] of sin is merely canceled or not imputed. The Council then proceeds to teach six things: (1) God hates nothing in those who are born again [i.e. those who are regenerated through the grace conferred in baptism], because by their baptism they have been buried together with Christ, put off the old man, put on the new man, made innocent, free from condemnation, immaculate, pure, guiltless, beloved of God, heirs of God, and heirs with Christ, so that nothing hinders their entrance into heaven, (2) In baptized persons there remains concupiscence, which is an inclination to sin, and which is left with us to wrestle with, (3) Concupiscence cannot injure those who do not give into it, but manfully resist it by the grace of Jesus Christ, (4) Those who have lawfully resisted concupiscence shall be crowned⁴⁰ (5) The Catholic Church has always understood concupiscence not to be sin in the sense that it is truly and properly sin in those who are born again, but to be sin in the sense that it is of sin (as an effect) and inclines to sin (as a cause), and (6) What this Council says about the universality of original sin in mankind should not be taken to apply to the blessed Virgin Mary.

Of all five paragraphs in the Fifth Session of the Council of Trent, this last one was the one most incompatible with the theology of Luther and Calvin. Luther and Calvin agreed that the grace of Christ that is conferred at baptism remits original sin. But, they denied that this grace removes the whole of that which belongs to the essence of sin. Instead, they claimed that sin remained in the baptized person, but the debt of sin was canceled, and the remaining sin was not imputed or counted. This is typically referred to as simul iustus et peccator (simultaneously justified and sinner), illustrated in the cartoon at right.⁴¹ Whereas in Catholic doctrine, the grace of Christ given to us through the sacrament of baptism truly removes all our sin, in Luther and Calvin’s opinion, the grace of Christ does not remove all our sin; it leaves sin in our soul, but by God’s favor on account of Christ, sin in our soul is no longer counted  against us.

Two things need to be said here. First, in Catholic doctrine, there is a sense in which that cartoon is correct, but there is also a sense in which that cartoon is heretical. In order to understand these two senses, we must distinguish between mortal and venial sin. Mortal sin removes agape from the soul; venial sin does not. That’s because in mortal sin the sinner directly chooses something else over God as his last end.  By contrast, the person committing venial sin still loves God more than himself, and still seeks God as his final end, but chooses something other than the best path by which to attain to God. Even the saints sinned venially every day (the Blessed Mother excepted). So, if the sign held by the person in the cartoon above is referring to venial sin, then it is true that the baptized person remains a sinner. But even so, it is not that Christ’s righteousness hides or covers his venial sin. God sees every venial sin. But He sees it as venial, as still coming from a heart that loves Him above all else. And so He sees it with mercy, not wrath. Yet if the sign in the cartoon is referring to mortal sin, then the cartoon is heretical, because then it is affirming the second error condemned in this fifth paragraph of the Fifth Session of Trent.

The reason why it is impossible to be simultaneously in a state of mortal sin, and justified, is because God cannot lie. God can only count as righteous that which is actually inherently righteous. That’s because the relational problem between man and God necessarily depends upon the internal condition of man. As St. Thomas said, “But the effect remains so long as the cause remains. Wherefore so long as the disturbance of the order remains the debt of punishment must needs remain also.”⁴² In other words, so long as man is turned away from God, and without agape, the debt of sin remains, because the cause of that debt remains. God does not only look at the outside of man; He looks at the heart, and is related to man according to the condition of the man’s heart.⁴³ If a man has sanctifying grace and agape in his soul, then his relation with God is one of friendship and he is justified, and the God who cannot lie cannot claim that he is unjust. But if a man does not have sanctifying grace and agape, then he is not a friend of God, and the God who cannot lie cannot say that he is just, without first making him just in his soul.

The Protestant response is to claim that God is speaking truly when He declares us just, because He performs an extrinsic relational transaction in which the merits of Christ are credited to our account, and the demerits of our sins are credited to Christ’s account. However, the problem with that position is that for a God from whom nothing is hidden, there can be no difference between what one is internally, and what is in one’s account. Necessarily, before the God of Truth, what is in one’s ‘account’ is always and only what one actually is. God cannot pretend that I am Christ or that Christ is me. God cannot pretend that my account is His, or that His account is mine. He always sees everything for exactly what it is, nothing more and nothing less. And therefore for a God of Truth, there can be no swapping of accounts. Because our ‘accounts’ are based on what we really are, the notion of account swapping presupposes that God is capable of deceiving Himself into thinking that Christ’s account is mine, and that my account is Christ’s. But a God of Truth cannot be deceived, and therefore there can be no swapping of accounts.

When Protestants think about being inherently righteous, they tend not to think about agape, but about having perfectly kept every law, and not having any wayward thoughts. And they tend to think that that is impossible, and so find forensic imputation much more plausible and attractive than this [seemingly] impossible standard of perfect legal righteousness that God expects of us. So, for example, they find vices in themselves after baptism, and take that as evidence that they are in fact unrighteous, and that provides the attraction of simul iustus et peccator. Yet in Catholic doctrine the law is fulfilled by those having agape,⁴⁴ and venial sins (by definition) do not remove agape from the soul. Our righteousness before God (as friends of God) is not determined by or effected by our venial sins. So, while at the Judgment we are judged for all that we have done in the body, yet, our justification only requires that we have agape. Not having the mortal-venial distinction makes many Protestants conceive of the Catholic life as one of losing justification many times a day. And that seems (rightly) ridiculous to them. But in Catholic doctrine it is agape by which we fulfill the law, and mortal sin (in which agape is lost) is not something we should (ordinarily) be committing on a daily basis.

The second thing that needs to be said about this fifth paragraph, concerns concupiscence (i.e. disordered appetites). The Catholic Church teaches that concupiscence is not itself a sin. Concupiscence comes from sin, and it inclines to sin. But it itself is not sin, because sin requires the use of the will.⁴⁵ , and the motions of concupiscence are not willed. We discussed this in Aquinas and Trent: Part 2. Nor is concupiscence original sin. Baptism removes original sin, by giving the person sanctifying grace. But baptism does not remove concupiscence. Christ leaves us with concupiscence so that we, by manfully resisting it, may merit a greater reward. The early Protestants, however, believed that concupiscence was itself sin. And therefore, finding concupiscence in themselves daily, even after baptism, and not recognizing  the mortal-venial distinction, they concluded that justification does not depend upon the internal condition of the sinner, but upon a forensic declaration. Because they [wrongly] believed that concupiscence was sin, and because they [rightly] believed that concupiscence remained after baptism, they concluded that after baptism there remains in us something that God hates, and for that reason were drawn toward to the notion of simul iustus et peccator.

From the Catholic point of view, the notion that we are simul iustus et peccator, where the sin in question is mortal sin, is extremely dangerous, because it leads people to think that their sin doesn’t really matter, so long as they continue to trust in God. This notion removes all motivation for pursuing the holiness without which no one will see the Lord.⁴⁶ It produces no saints. Its danger cannot be underestimated, because what is at stake is eternal life. The notion of simul iustus et peccator could lead persons who are in a state of mortal sin, and thereby at risk of dying in a state of mortal sin and remaining eternally separated from God, to think that they are right with God. Of course some Protestants think that the Catholic Church teaches a false gospel. I will address that when we discuss the Sixth Session of the Council of Trent, on the doctrine of justification.

May Christ our Lord lead all Protestants and Catholics to unity in the truth, and full reconciliation. In the Name of the Father, and of the Son, and of the Holy Spirit. Amen.

12. Pelagianism ultimately reduces to one of two claims: it either denies that man has a supernatural end, and thus denies that man needs grace [i.e. participation in the divine nature] to attain man’s natural end, or it denies that grace is a participation in the divine nature, and thus implies that man, by his own natural power, can attain to the supernatural end that is heaven. The former denies that God has called man to enjoy eternal participation in His inner Life. The latter essentially denies the Creator-creature distinction. It claims that man, who is infinitely below God, can by his own natural power of intellect and will ‘climb up’ into the inner Life of the eternal Trinity. [↩]

14. All virtues have as their final scope to dispose man to acts conducive to his true happiness. The happiness, however, of which man is capable is twofold, namely, natural, which is attainable by man’s natural powers, and supernatural, which exceeds the capacity of unaided human nature. Since, therefore, merely natural principles of human action are inadequate to a supernatural end, it is necessary that man be endowed with supernatural powers to enable him to attain his final destiny. Now these supernatural principles are nothing else than the theological virtues. They are called theological: (1) because they have God for their immediate and proper object; (2) because they are Divinely infused; (3) because they are known only through Divine Revelation. The theological virtues are three, viz. faith, hope, and charity [agape]. (Catholic Encyclopedia article ‘Virtue‘.)

28. This becomes relevant to Session 6 Canon 9, because that canon is condemning the notion that merely believing the message about Christ is entirely sufficient for justification, and that repentance (as a preparation for baptism) and baptism itself are not also necessary for the justification we receive through the sacrament of baptism, wherein belief in Christ is made to be the virtue of faith.
