Within the realm of Christian theology there are many fiercely debated topics. One such topic is the question of the how the Law is to be understood in the Christian faith, especially in the light of the gospel and in the life of the Christian.
Taking on this task, Reformation thinkers Martin Luther and John Calvin both put forth ideas of how the Law is to be understood within Christianity.
When given a cursory reading, it will be noticed that Luther put forth two different uses of the Law, whereas Calvin put forth three, a distinction which has caused a fair amount of dispute between Lutheran and Reformed theologians to this day.
In order to gain a better understanding of this doctrine is helpful to compare and contrast these two great thinkers’ views on the topic, paying careful attention to how and why they draw the distinctions that they do. For John Calvin, it will be necessary to analyze his Institutes of the Christian Religion, where he lays out what he sees to be the three uses of the Law. For Martin Luther, it will be necessary to first look at his Commentary on Galatians, where he lays out what he sees to be the two primary uses of the Law; with this done, it will also be necessary to look at various other of Luther’s writings to discern whether or not he indeed limits the use of the Law to those two areas.
Because Calvin is more systematic in his approach to the topic of the uses of the Law, it will be helpful to discuss him first, and thereby gain a solid understanding of the field to be analyzed; with this done we can consider how Luther compares in his writings, both explicitly and implicitly.
John Calvin’s Three Uses of the Law
What the Law Refers To
In discussing Calvin’s uses of the Law, it is first necessary to discern what it is that Calvin refers to when he refers to the Law.
For this one may turn to the seventh chapter of the second book of Calvin’s Institutes of the Christian Religion, where Calvin begins his in-depth discussion of the Law. Here Calvin states explicitly that ‘the Law’ he understands to refer to “not only the Ten Commandments, which contain a complete rule of life, but the whole system of religion delivered by the hand of Moses.”
This definition of the Law is given in the context of pointing out that the Law is not something that exists merely as a negative, detracting from the hope of Israel for Christ. Rather, Calvin argues that this was given through Moses for the sake of ‘renewing’ the Abrahamic promises, to be seen as “types and shadows of corresponding truth.” Thus Calvin begins his discussion of the Law by pointing out that the Law is not a bad thing. Indeed, Calvin goes so far as to say in reference to the religious aspect of the Law that “the fullness of grace, of which the Jews had a foretaste in under the Law, is exhibited in Christ,” in reference to the priestly offices that they would come to inhabit.
After this ceremonial and religious aspect of the Law, Calvin goes on to discuss the more explicitly moral aspect of the Law, which serves to point out the fact that eternal life awaits perfect obedience of the Law. By this the Law serves to show that the people fall under the curse, the result of which is “despondency, confusion, and despair.” Regardless, Calvin notes, the fact that perfect obedience to the Law is nowhere to be found does not mean that the Law has therefore been given in vain, for through justification by faith the people learn to embrace the goodness offered in the gospels.
The ‘office’ of this moral law, Calvin continues, itself consists of three parts, which is where one enters fully into Calvin’s understanding of the three uses of the Law.
Three Uses of the Law: Serving as a Mirror
In beginning his discussion on the three parts of the moral law, Calvin first points to the use of the law as it exhibits “the righteousness of God – in other words, the righteousness which alone is acceptable to God.”
Pointing out what righteousness is acceptable to God in turn convicts and condemns the people of their pride and serves as “a kind of mirror” in which “we discover any stains upon our face” such that the people will observe their own impotence, iniquity, and the curse and consequence of those. This aspect of the Law is that aspect experienced by those who are “sinners not yet regenerated.”
In continuing his defense of the Law, Calvin points out that the fact that the Law serves to only condemn does not detract from the excellence of the law, since the reason the Law is insufficient for salvation is because of our lack of obedience, and thereby not any fault in the Law itself. The Law if further not marred because God has declared that his end goal is not to “allow all to perish” but to that he might take mercy upon them by turning them to the mercy offered in Christ.
Thus, the first use of the law is that it serves as a mirror, showing mankind their iniquity and convicting them of their subsequent condemnation, and through this driving them to take refuge in the mercy of God in Christ.
Three Uses of the Law: Serving as a Curb
The second use of the Law, Calvin argues, is that through the fear of punishment that it might “curb those who, unless forced, have no regard for rectitude and justice.” These individuals have their behavior curbed, Calvin argues, not because their hearts are changed or they are “inwardly moved and affected”, nor do they change their behavior in order to better please God. Rather, they are restrained through the force of “terror and shame”, terror of the punishment which will come to them if they act against the Law, and the shame which will be attached to their actions.
This outward restraint does not lead to an inward change of heart; just the opposite, due to having to restrain themselves Calvin argues that they become even more hostile to God – the Lawgiver – more inflamed, such that they “rage and boil”, ready to break out whenever the fear of the law is gone.
In spite of the fact that this aspect of the Law doesn’t avail in changing the hearts of those who are under it, Calvin argues that it too is still a good thing. This goodness comes not from the impact of the Law upon those whom it inflames, but on the overall good of society. This is so because through restraining these individuals society’s peace is “secured by a provision but for which all things would be thrown into tumult and confusion.”
Furthermore, even though the unregenerate might not be driven to holiness by this aspect of the Law, Calvin argues that it does train those who will eventually be converted in how to “bear the yoke of righteousness.”
That is, it gives them a sort of head start in what it is like to live as a Christian. Lastly, this use of the law for these individuals keeps them from “giving full scope to their passions, and thereby utterly losing all desire after righteousness.” Calvin here argues that the law keeps the yet-to-be-regenerated individual from giving in fully to their passions and thereby retaining in them at least some desire for righteousness. This is such that should God not immediately bring an individual to salvation, he may prepare them for salvation by cultivating that rightful fear which a child ought to have of their Father.
Thus, in its second use, the law serves both the good of society in restraining individuals from wicked behavior as well as cultivating in some of those individuals the discipline and fear that they should rightfully have when they eventually become children of God.
Three Uses of the Law: As a Rule of Life
In his commentary Calvin notes that there is a tendency for theologians to relegate the entire use of the law to the increase of transgressions as presented in Galatians 3:19. He goes on to note that Paul speaks of the law as profitable for doctrine and notes that “the definition here given of the use of the law is not complete, and those who refuse to make any other acknowledgment in favor of the law do wrong.”
Following his discussion of the uses of the law as a tool for turning people toward reliance on God and as a tool for curbing behavior which would be harmful to society, Calvin turns toward what he refers to as the ‘principal use’ of the Law, and what is known in theology at large as simply ‘the third use of the Law’.
This use of the Law differs from the previous two uses in that while the first two uses of the Law apply – in Calvin’s system – primarily to the unregenerate, this third use is the Law as it is applied to the regenerate, to believers who are already following God.
In speaking of this use of the Law, Calvin begins by pointing out that believers already have the Law written on their hearts along with a desire to obey God. In light of this state of believers Calvin says that there are still two different ways that the Law can be useful for them. The first of these ways is that the Law is still the “best instruction for enabling them daily to learn… what that will of the Lord is which they aspire to follow.”
That is to say, study of the Law increases the wisdom of the believer in regards to what the will of God for them is. The second of these ways is that through meditating on the Law, Calvin asserts that the believer will be further motivated toward obedience and further drawn away from the temptation of sin; this can perhaps be best summed up in Calvin’s statement that “If it cannot be denied that [the Law] contains a perfect pattern of righteousness, then, unless we ought not to have any proper rule of life, it must be impious to discard it.”
In this the Law no longer serves to condemn the believer – even though they still cannot live up to it – but it points believers toward the goal to which we strive and exhorts them in this task, exhorts them in the task of working towards perfection as a rule of life.
From what has been observed it can be seen that Calvin allotted three uses to the Law. Firstly, it serves as a mirror to show us our unrighteousness and drive us toward dependence on God. Secondly, it serves as a curb to keep those who wish to do evil in check through fear of the punishments associated with the Law. Thirdly, it serves as a rule of life for believers to follow, instructing them in the will of God which they seek to follow.
One of the areas of note here is that in Calvin’s approach to understanding the different ways in which the Law operates, he places a great emphasis on the the Law as it applies to the unregenerate versus the Law as it applies to the regenerate. Thus, the first use applies to the nonbeliever, to drive them toward God. Similarly the second use applies to the nonbeliever, to curb their wicked desires. The third, contrary to these, applies to the believer, giving them a guide to Christian living.
Martin Luther’s Two Uses of the Law
While Calvin is very systematic in his approach to the Law, Luther is somewhat more sporadic and – indeed – pastoral and periodic, addressing his concerns more in response to a given issue rather than developing out each of his ideas in strict logical fashion.
For this reason it is necessary to look at a variety of Luther’s works, centering around his Commentary on Galatians, in which he presents his case for the two different uses of the Law.
Law and Gospel; Active and Passive Righteousness; Sinner and Saint
In looking at Martin Luther’s use of the Law, it is helpful to see how it is that he relates the one notion of the Law to the other of the Gospel, what he calls the active righteousness of the one to the passive righteousness of the other.
Luther begins his Commentary on Galatians with a discussion of the various types of righteousness. After a brief mention of the civil righteousness of abiding by the laws of the state and the ceremonial righteousness of the manners taught by parents, Luther enters into a discussion of the righteousness of the Law – as exemplified in the Ten Commandments – and the righteousness of faith.
These latter two types of righteousness differ from one another in that the righteousness of the Law is what Luther refers to as an active righteousness, a righteousness which actively seeks to fulfill God’s Law. Luther notes this active righteousness as being in vain, through which “sin is made exceedingly sinful.”
In realizing the vainness of this active righteousness, the person then turns to embrace the passive righteousness of Christ. Thus, the unbeliever is to oppressed with the Law until they are “thirsting for comfort”, at which time the Law is removed and the Gospel is placed before them. In turn, Luther argues, both Law and Gospel are necessary, but “both must be kept within their bounds” where the righteousness of the Law applies to the ‘old man’ and the righteousness of faith to the ‘new man’.
This notion is imperative to properly understanding Luther’s understanding of the Law, for the ‘old man’ and the ‘new man’ does not merely refer to the unregenerate and the regenerate.
Rather, the ‘old man’ and the ‘new man’ exist both within the believer, hence Luther states that “a Christian man is both righteous and sinner, holy and profane, an enemy of God and yet a child of God.” In the same way he asserts: “both these continue whilst we here live. The flesh is accused… bruised by the active righteousness of the law; but the spirit reigneth, rejoiced and is saved by this passive and Christian righteousness.”
Further on in his commentary he builds upon this notion, asserting that though he commits sins, these do not plague his conscience since he knows he is in Christ; instead he directs the chastisement of his sins towards his body, making the point that the Law cannot touch the conscience, though it may be directed towards the flesh.
It is only with this dual nature of man in mind that one may move on to understand the way that Luther appropriates the Law.
Two Uses of the Law: The Civil Use
When it comes time for Luther to discuss the nature of the Law in a more systematic manner, he states that there is a double use of the law. This first use, he argues, is the civil use. The civil use, simply put, is that the law is given in order to restrain sin. This restraint of sin does not lead to righteousness; rather, the very fact that there are sin to be restrained is signal that the individual is unrighteous, for it is only person who is prone to sin who needs to be threatened against sinning. Thus, this first use of the Law is “to bridle the wicked.” For this purpose there have been created governments and civil ordinances, ready to bind the person who acts against the law. While this use of the law does not produce salvation, it does provide for the public peace and “the preservation of all things.”
Two Uses of the Law: The Spiritual Use
Following his discussion of the civil use of the law in his Commentary on Galatians, Luther then turns to discuss what he calls the ‘theological’ or ‘spiritual’ use of the Law.
This use of the Law, as Luther argues, is that it is used in order to reveal to man his sin and his contempt of God, and in turn reveal the judgment and wrath which the man deserves from God. This use, Luther argues, is “the proper and the principal use of the law.”
The purpose of the law is thereby to terrify, to “rend in pieces that beast which is called the opinion of righteousness.” That is, the purpose of the law is to defeat the pride of the individual, to reveal sin, and to make the individual feel the burden of the law so that they might despair.
This use of the law Luther connects with God’s work at Mount Sinai, the place where Moses received the Ten Commandments, which “brought that holy people into such a knowledge of their own misery, that they were thrown down even to death…” On top of this use of acting as a mirror, one finds in Luther’s other writings that he is willing to connect the law driving the individual “to despair of himself” with the result that it causes them “to seek the help which he does not find in himself elsewhere.”
Other Uses of the Law in Luther
It is noteworthy that in his Commentary on Galatians, Luther only points to two uses of the Law. Yet, if one looks to his other writings, a larger picture begins to appear. Thus, in Against the Heavenly Prophets, one may find Luther writing of the five different articles of the Christian faith. The first is the law of God, the second the gospel. The third article is what Luther calls ‘judgment’, which is “the work of putting to death the old man”, and it is followed by the fourth article of “love toward the neighbor”, and a fifth article to “ proclaim the law and its works” to the “crude masses” such that they will “know what works of the law they are to do and what works ought to be left undone”; yet these works are not put before the Christian “as if one through them were upright or a sinner.”
Luther does not answer directly here the question of how one is to put to death the old man, or where one might look to discern what it is to love one’s neighbor, yet in his Instructions for the Visitors of Parish Pastors he gets closer to doing so, stating that the “third element” of Christian life is “the doing of good works”; works which include “to be chaste, to love and help the neighbor, to refrain from lying, from deceit, from stealing, from murder… [etc].” Here Luther lays out at least four of the ten commandments as the ‘doing of good works’ which is an element of Christian life.
One may also turn to the most practical area of Luther’s writings, his catechisms.
Here Luther’s addresses the Ten Commandments in the life of the Christian, instructing his readers that they should not act contrary to the Commandments, that God promises blessings to those who keep the Commandments, and that Christians should “gladly do according to His commandments.”
In his Larger Catechism he then states that the one who knows perfectly the Ten Commandments will be able to “counsel, help, comfort, judge, and make decisions in both spiritual and temporal matters.” He later follows this statement up with the assertion that the Ten Commandments are “the true channel through which all good works must flow,” that doing these works will result in God’s blessing, and that “everyone is to make them his daily habit in all circumstances.”
Yet in contrast to this there is also the idea present in Luther’s Concerning the Letter and the Spirit that since the Christian “lives in the Spirit as the law demands; indeed, he no longer needs any law to teach him, for he knows it now by heart… there no teaching or law is needed; everything happens as it should happen.”
In figuring out how these apparent works of the law can be present in the Christian life of good works, it is necessary to see a further distinction Luther makes in his writings. In his Lectures on Romans, Luther makes the point that ‘the works of the Law’ are those that take place at the urging of the law, while the works of faith are those done “solely for the love of God.”
Thus, it could be argued that for Luther the same act could be either a work of the law or a work of faith, depending on the motivation for the act; “thus we gain a genuine desire for the law, and then everything is done with willing hearts, and not in fear.”
In light of this it is not incongruent for Luther to utter statements such as the one that the Christian should call upon God “according to the second commandment.”
Similarly, when Luther adamantly asserts that there is not teaching of the law and no need for the law, it seems that this should be read firstly to mean that there is no teaching of the law-as-condemning-force.
Luther’s practical use of the Law seems to demonstrate that when Luther talks of the Christian not needing the Law to teach him due to him knowing it by heart, he seems to be speaking more idealistically, of the ideal Christian.
In all of these other writings of Luther it may be observed then: (1) adhering to the law works nothing for justification; (2) yet there are good works to be done by the Christian, and that these ‘good works’ include acts synonymous with certain commandments of the Law, for indeed, the heart has been changed to naturally act out the Law; (3) that the Christian should abide by the Ten Commandments, which will result in his being blessed by God; (4) that it is the motivation behind these acts that distinguish them from being ‘works of the law’, such that when done for the glory of God it is no longer law but faith.
In summing up his view on the two different uses of the law Luther states that “the law is good and profitable, but in his own proper use; which is, first to bridle civil transgressions, and then to reveal and to increase spiritual transgressions.”
The Law, for Luther, is primarily a light, but one that shows only sin and death. The Gospel, on the other hand, is a light which shows the mercy of God in Christ.
There are various noteworthy aspects to understanding Luther’s understanding of the Law. One of these aspects is the way in which Luther’s second use of the law is already contained in his first use of the law. As he said, the first use is to bridle the wicked, and the very fact that they need a bridle demonstrates that they are wicked, at least in a general way. The second use, then, narrows down this general demonstration of wickedness to terrify and convict the individual. This restriction and conviction is the extent of the Law for Luther.
Rather than go any further than this, where the Law ends for Luther, the Gospel may begin. The Law makes the individual despair so that the Gospel may come and give hope, the active righteousness of trying to live up to the law is replaced with the passive righteousness of Christ.
Most noteworthy in Luther’s understanding of the Law is that his primary focus is upon the old man verses the new man.
This is important because both the old man and the new man exist in the person of the believer. Thus, when the old man causes the individual to sin, the Law points to that sin in the life of the believer, but it doesn’t convict, for then the righteousness of Christ – the Gospel – is there to cover the sin. Yet in this it can be noted that the Law does still exist in the life of the believer for Luther, as he says: “among Christians we must use the law spiritually, as is said above, to reveal sin.”
In the writings of Luther as a whole it was observed that Luther does – in practice – use the law for more than merely keeping the wicked in check and revealing sin. He also seemed to promote good works as a Christian – works of faith – which were synonymous in content with the works of the Law, with the difference that they were done not out of the fear of the condemnation of the Law, but out of love for God and the desire to be blessed. In desiring to do these good works Luther advises the believer to meditate on the Ten Commandments, the same Ten Commandments he also equated with the righteousness of the Law.
Thus it might be observed that while in some instances Luther seems to clearly reject out of hand the use of the law in the life of the Christian, it seems that this may be in large a semantic error of Luther simply refusing to refer to this use of the law as a guide as a use of the ‘law’, for he desired to equate this with faith rather than Law.
In contrast to this it might be contended that “love by its very nature is ready to serve and be subject to him who is loved” and that because the new man does not need the Law as an instruction, for the Law is written on his heart and he will act this out naturally and spontaneously; yet, Luther’s practical use of the Law seems to assume that the Christian can get instruction in good works from the law, and it is simply that fact that when discussing this facet Luther refrains from referring to it as the law.
Comparing & Contrasting Luther and Calvin
In comparing and contrasting Luther and Calvin there are many things which can be discussed. Perhaps the best place to start with this is to figure out where the two thinkers agree.
The first use of the Law that Luther put forward was what he called the civic use, which was noted as serving the purpose of bridling sin for the good of the society through the fear of the law. In the same way Calvin’s second use of the Law was that it served the purpose of curbing sin for the good of society through the fear of the law. In this use of the law Luther and Calvin seem to be in full agreement; there is only the relatively minor difference in how Luther points out that this use indicates the wickedness of man, whereas Calvin points out that this use serves the dual purpose of further inflaming the wickedness of man and training those who do not yet believe.
The second use of the Law put forth by Luther was what he called the spiritual use. In this way the law was used to terrify and convict people of their sin, to reveal their sin to them as in a mirror. Furthermore, whereas in his Commentary on Galatians he left the second use at that, in his Freedom of the Christian Luther alluded to the fact that this despair drives the individual somewhere besides themselves. In like manner, Calvin’s first use of the law was that of a mirror. This mirror shows people their unrighteousness and convicts them of their impending condemnation, and through this drives them to take refuge in the mercy of God in Christ.
While this second set of uses for the law by Luther and Calvin, both serving as mirrors, seem to be identical, there is an important distinction to note. This distinction is that – for Calvin – this mirror’s purpose rests in convicting the unbeliever, the unregenerate. Calvin’s mirror seems to only be for the unregenerate man prior to his conversion. In contrast to this, Luther’s mirror is ever present.
This is because rather than focusing on the regenerate/unregenerate distinction, Luther focuses on the old/new man distinction, and this is a distinction which stays with the believer even after regeneration.
Therefore, while Calvin’s mirror is used by the individual prior to conversion, Luther’s mirror is used by the individual both before and after conversion, a fact which will be important when analyzing the different ways the two thinkers apply the law in the believer’s life.
With this in mind, one may then turn to the third use of the Law as presented by Calvin.
It was noted that for Calvin, this use was the one in which the law served to instruct and guide the believer after conversion, increases the believer’s wisdom in regards to the will of God. With regeneration, the individual is able to make the move from using the Law as a mirror to using it as a guide.
Luther would have been unable to follow Calvin here for a variety of reasons.
Firstly – as has been noted – Luther’s focus was not on the regenerate/unregenerate distinction. Because for Luther the old man is always there with the new man – and because the mirror applies to the old man – the individual is never fully able to put the mirror down.
Thus, for Luther, when the Law comes up it necessarily comes up as that mirror.
Because the old man is always present in the life of the individual, the Law must always serve the purpose of driving that old man to despair, that he might find relief in the Gospel.
This sharp Law/Gospel distinction is important for understanding Luther in that whereas Calvin was comfortable placing a close connection between the Law revealing sin and in turn driving the individual toward Christ (and thereby having the Gospel implicit in the Law), Luther drew a much sharper distinction between Law and Gospel; thus for Luther the most the Law could do in revealing sin was drive the individual away from themselves, he doesn’t take the next step with Calvin in asserting that it drives them to Christ.
Rather that asserting that the Law drives the unbeliever to Christ, Luther prefers to speak of the move in terms of the Law driving them solely to despair and then the Gospel coming in as a balm and a comfort.
Thus, not only does Luther have an old/new man focus over against Calvin’s regenerate/unregenerate distinction, but Luther also has a much sharper separation of the law from the gospel than Calvin.
Yet, Luther also has a stronger connection between them in another sense, for in Luther both the law and the gospel are ever present and presented together.
The old man is always present, and therefore the law must always be there to terrify, and at the same time the gospel always be there to comfort. When talking of the Christian as a whole, Luther still has a place for the law, which is, for condemning the works of the old man in the body of the believer. He does not expel the law from the life of the believer, but he takes care when referring to ‘the law’ to refer to it in exclusive reference to the old man.
While asserting that Luther cannot follow Calvin into Calvin’s formulation of the third use of the Law due to the differing angles at which each thinker is approaching the Christian system, Luther does have his own variety of this.
Whereas Calvin’s third use is the Law applied to the regenerate man, Luther’s ‘third use’ might be said to be the Law applied the ‘new man’ (though as noted above Luther would not use that language).
While this sort of use was not discussed systematically by Luther, it is implied in various of his writings. In this it was observed Luther suggesting that knowledge of the Ten Commandments made one able to make decisions in both spiritual and temporal matters, that good works flowed from them, good works which would cause God to bless the individual.
Yet, while a position such as Calvin’s this might seem to roughly fit the criteria of his third use of the law, the distinction for Luther was that – at least semantically – these are not uses of the law. A use of the law for Luther would have been something that was necessarily done under compulsion, and therefore incompatible with good works or the faith of the Christian. Rather, these same works are works of faith – not works of law – even when they are centered around the same principles as the ‘law’.
In light of this analysis, it might be stated that while Calvin and Luther do have some genuine differences in their approaches to way the Law is to be used, much of this difference can be attributed to viewing the same truths from different angles and with different foci; this is to be expected, for these men existed within space and time and were reacting against their own given environments.
Though a detail of biographies was outside the scope of this study, it might be noted – for instance – that Luther was much more closely tied to his reaction against the abuses of Rome, and this reaction shaped how he focuses his theology.
On top of this difference of foci, Luther and Calvin are also separated by what it is often the hardest bridge to cross in theology, the bridge of semantics.
To a large extent the approaches taken by Luther and Calvin to the Law have the same result and are getting at the same points, but using different categories and different terminology which makes the similarities difficult to see.
Thus, Calvin uses the Law as a guide for believers, whereas Luther also in practice uses that same Law as a guide, but is careful not to refer to it in that manner due to way that he has defined ‘Law’ in his understanding; it is simply incongruent for Luther to imagine applying the term ‘Law’ to something utilized by the new man, for the Law to him can only apply to the old man.
Yet, there are still differences here, and these differences do affect the way Christians go about their lives. The way in which Luther keeps the mirror of the Law at hand, and in turn the comfort of the Gospel, has the practical result of constantly driving the individual back to the Cross for their comfort.
This can be a helpful attitude to take when dealing with sin; and yet it can also be helpful to have a guide to aid one in avoiding sin and for instructing one in how to live a life pleasing to God. Calvin’s focus is more helpful in addressing this aspect of the Law.
Thus, it can be asserted that neither John Calvin nor Martin Luther is necessarily ‘correct’ in this matter.
When they discuss the uses of the Law they are seemingly discussing the same matter, but they are discussing it in very different manners for different reasons, with different foci and different terminology. Neither has the perfect system, and neither has a defunct system; rather, each has a system which is helpful and unhelpful in turn, true and false in differing ways.
In looking back over these various uses, it can be found that they all have some legitimacy. The civic use of the law found in both Luther and Calvin is viable in either context. Calvin’s first use of the law is helpful for bringing the unbeliever to faith, and yet as it is used in Luther, it also serves a use in the life of the believer, continuing to drive them to Christ and the rest that He provides, as well as subdue the flesh; Calvin can be corrected by Luther here, in that the mirror may still have a use after conversion. Finally, with Christ as the goal, Luther may be corrected by Calvin in noting that it can be helpful for the Christian to gain wisdom of God’s will through the study of the law.
