A Foundational Inquiry into Grace, Free Will, and the Interpretation of Scripture
Book One, Question One: The Problem of Romans 7 and the Law
We are at the very opening of the work, where Augustine addresses Simplician’s first query concerning the meaning of Paul’s epistle to the Romans, specifically the passage from Romans 7:7–25, which deals with the relationship between the law, sin, and the human will.
Augustine begins by acknowledging that Simplician has asked him to explain the difficult passage in which Paul writes, “I had not known sin, but by the law: for I had not known lust, except the law had said, Thou shalt not covet” (Romans 7:7). Augustine immediately identifies the central puzzle: if the law is holy, just, and good, how can it be said to provoke sin? He presents the Apostle’s own logic: the law enters so that sin might increase, for without the law sin is dead — yet the commandment that was intended to bring life actually brings death, because sin seizes the opportunity afforded by the commandment to produce all manner of covetousness. Augustine insists that this is not a condemnation of the law, but a revelation of what sin truly is. The law serves as a mirror, showing the will its own impotence. Before the law, humans might think themselves able to fulfill righteousness by their own effort; when the law commands what they cannot do, their sin becomes “exceedingly sinful” precisely because it is now transgression against a known command, not mere ignorance.
Augustine then walks through the Apostle’s cry: “For the good that I would I do not: but the evil which I would not, that I do” (Romans 7:19). He argues that this statement cannot apply to Paul himself, the enlightened apostle, but must be read as Paul speaking in the person of the old man — the unregenerate person still under the law, not yet under grace. The key distinction is between being under the law and being under grace. A person under the law knows what to do but lacks the power to do it; the law commands but does not help. The will approves the law’s goodness, but this very approval shows that the will is divided — it wants to obey, yet it is overpowered by the flesh, the inherited habit of sin. Augustine describes this as a war in which the mind serves the law of God, but the flesh serves the law of sin. This is not a description of the Christian’s normal state, but of the state of someone struggling without the aid of the Holy Spirit.
Augustine clarifies: “The law therefore was given that grace might be sought; grace was given that the law might be fulfilled.” The purpose of the law is not to save by itself, but to drive the proud soul to despair of its own strength and thus to cry out for a physician. The law functions as a schoolmaster that leads to Christ, not by enabling obedience, but by demonstrating the impossibility of obedience without grace. The person who tries to fulfill the law by his own will becomes aware that his will alone is insufficient; this awareness is the first step toward humility and toward seeking the help of God. The law does not heal the will; it exposes the wound. In this way, the law is not evil but good — a diagnosis that points toward the only cure.
Book One, Question One (continued): The Will, Grace, and the Call of God
We remain within the same question, but now Augustine turns from the general problem of the law to a more specific analysis of how the human will operates in relation to God’s call and the gift of grace.
Augustine presents the core difficulty: if the law cannot save, and if grace alone enables obedience, then how does human freedom remain meaningful? He cites Paul’s own words: “It is not of him that willeth, nor of him that runneth, but of God that sheweth mercy” (Romans 9:16). This seems to suggest that human willing is irrelevant. Augustine responds by distinguishing between the natural capacity to will and the power to do good. Every human being has a will, but the will is not free in the sense of being equally capable of good and evil. Before the fall, Adam possessed a free will that could choose either righteousness or sin without any internal compulsion. After the fall, the will is wounded; it retains its freedom to choose among various objects, but it is captive to sin, meaning it cannot, by its own natural power, choose the highest good — God. The will is free in the sense that it acts voluntarily, but it is bound in the sense that it cannot escape its own disordered desires.
Augustine uses the example of someone who desires to rise from bed but is held down by a heavy chain. The person wills to rise, but the chain prevents it. So too, the human will may genuinely wish to obey God, but the chain of concupiscence — the inherited habit of sin — holds it down. The will is not destroyed; it is impeded. Grace is the power that breaks the chain, not by forcing the will against its inclination, but by changing the inclination itself. Augustine calls this the delight of the will: when God gives grace, He infuses a new sweetness, a new pleasure in righteousness, so that what the will previously loved (sin) becomes distasteful, and what it previously could not love (righteousness) becomes desirable. The will is not coerced; it is healed. The person now wills freely what before he could not will, because the object of his love has been transformed.
Augustine then addresses the question of why God calls some and not others. He insists that the call of God is not based on any foreseen merit in the person. Paul says, “Jacob have I loved, but Esau have I hated,” before either had done anything good or evil. Augustine interprets this to mean that God’s choice is entirely gratuitous — it is an act of unmerited mercy toward some, and just judgement toward others. The difference between the saved and the lost is not in their wills, but in God’s hidden decree. Yet Augustine immediately warns against despair: the fact that God’s choice is hidden does not mean it is arbitrary or unjust. God owes mercy to no one; He owes justice to all. If He punishes all, He is just; if He saves some, He is merciful. The will of the saved person cooperates with grace, but this cooperation itself is a gift — the will to cooperate is given by God. As Augustine writes: “He who wills and he who runs are nothing, but God who shows mercy is everything; yet the one who wills and the one who runs are still themselves, but they will and run only because God works in them both to will and to do.” There is no part of salvation that belongs to human effort as an independent contribution; all is from God, yet the human person truly acts.
“Therefore, the law was given so that grace might be sought; grace was given so that the law might be fulfilled.”
This passage crystallizes Augustine’s entire argument in this question. The law has a pedagogical function: it does not enable, but it reveals, humbles, and drives the soul to seek help. Grace does not abolish the law; it fulfills the law by giving the will the power to obey what the law commands. Without the law, the soul is complacent; without grace, the soul is condemned. The law and grace are not enemies but stages in a divine pedagogy — the law exposes the illness, grace heals it. Augustine is careful to preserve both the reality of human willing and the absolute priority of divine action. The will is not passive; it actively wills and runs. But the very act of willing good is a gift, because the will cannot heal itself any more than a blind person can restore his own sight. This is Augustine’s mature understanding of grace, developed precisely through wrestling with Romans 7 and 9: human freedom is real, but it is only truly free when it is liberated by grace to love what is good. Outside of grace, the will is free to choose among evils, but not free to choose the Good itself.
Book One, Question Two: The Interpretation of Romans 9 and the Potter’s Clay
We move to the second question of Book One, where Simplician asks Augustine to explain Paul’s controversial discussion of God’s hardening of Pharaoh’s heart, the potter’s power over the clay, and the apparent injustice of God choosing some for salvation and others for destruction — all from Romans 9:14–23.
Augustine begins by acknowledging the gravity of the question: how can God be just if He hardens whom He wills and then punishes the hardened for their sins? The objector, whom Augustine channels through the Apostle’s own wording, would say: “Why doth He yet find fault? For who hath resisted His will?” (Romans 9:19). If God’s will is irresistible, and if He hardens Pharaoh without any apparent cause in Pharaoh’s own action, then it seems God is the author of sin and cannot justly punish the sinner. Augustine insists that this objection misunderstands both the nature of God’s justice and the nature of human sin. He argues that God does not harden anyone by creating evil in them, but by withdrawing His grace — a punishment that is justly deserved because of original sin, which all humans inherit from Adam. All humans are born as a mass of sin (massa peccati), a lump of clay that is worthy of destruction. God owes mercy to no one. If He does not give grace, the will remains in its natural state of bondage to sin, and the person sin freely and voluntarily. Pharaoh’s hardening was not God actively making him evil, but God justly leaving him to his own wicked will.
Augustine then develops this by distinguishing two kinds of divine action. On the one hand, God works internally to convert the will — this is mercy. On the other hand, God works internally to leave the will to itself — this is judgment. The same sun that melts wax hardens clay; the same divine presence softens the hearts of the elect and hardens the reprobate. But the difference is in the nature of the material, not in the sun itself. Using this analogy, Augustine argues that God’s call is one, but it produces different effects depending on the condition of the heart. However, he immediately corrects this: the condition of the heart is itself a result of God’s grace or the lack thereof. The “material” is not neutral; it is already corrupted by original sin. God does not find some hearts soft and others hard; He makes the soft hearts soft by His grace, and He leaves the hard hearts hard by His just judgment. No one can claim that God is unjust, because all deserve destruction. If God saves some, it is pure mercy; if He punishes others, it is pure justice. Both are good, because justice is good and mercy is good. The mystery lies in why God chooses this one and not that one — a secret Augustine does not attempt to penetrate, but he insists that it is a hidden wisdom, not an injustice.
Augustine uses the image of the potter from Romans 9:21: “Hath not the potter power over the clay, of the same lump to make one vessel unto honour, and another unto dishonour?” He explains that the “same lump” refers to the single mass of humanity, all condemned equally by original sin. The potter (God) makes vessels of honor (the elect) by His merciful grace, and vessels of dishonor (the reprobate) by His just judgment. The dishonor of the reprobate is not something God inflicts as an evil; it is simply allowing the lump to remain in its natural dishonor. The vessels of honor are not honored because of any merit in the clay, but because of the potter’s free choice. Augustine emphasizes that this is not fatalism or determinism in the pagan sense: human actions are real, and humans are responsible for their sins. The reprobate sin because they love sin; they are not compelled to sin against their will. But their will is justly left in bondage to sin, because they are part of the mass of perdition. The saved, on the other hand, have their will freed by grace, so that they both will and do good, but this willing itself is a gift — the potter has made them vessels of honor.
“Both mercy and judgment are in the hands of God. Judgment is rendered to those who deserve it; mercy is given freely to those who do not deserve it.”
This passage sums up the theological logic Augustine employs. All human beings, as descendants of Adam, are a condemned lump; no one has a claim on God’s mercy. If God punishes all, He is just; if He saves some, He is merciful. The problem of why God saves some and not others is not a problem of justice, because justice does not require mercy — mercy is always gratuitous. Augustine’s point is that the question “Why this one and not that one?” cannot be answered by pointing to any foreseen difference in merit, for none exists. The only answer is the inscrutable will of God. But this is not a cruel or arbitrary will; it is a will that is itself the highest justice and the highest goodness, even if its reasons are hidden from human understanding. The purpose of this entire discussion is to humble human pride: if salvation depended on human will or effort, then people would boast. Instead, “he that glorieth, let him glory in the Lord.” This is the foundation of Augustine’s theology of grace, which he develops here with unprecedented precision, responding directly to the objections that would later resurface in the Pelagian controversy.
Book One, Question Three: The Governance of the Will and the Nature of Temptation
We are now in the third question of Book One, where Augustine turns from the specific problems of Romans 7 and 9 to a broader inquiry into how God governs human wills, particularly in relation to temptation, sin, and the testing of faith.
LOCATE: This question addresses a practical and pastoral problem emerging from the previous discussion: if God is sovereign over the will, how do we understand the process of temptation, the role of the devil, and God’s permission of evil in the lives of believers?
PRESENT: Augustine begins by examining the mechanism by which a person falls into sin. He argues that temptation operates through a three-stage process: suggestion, pleasure (*delectatio*), and consent (*consensus*). The suggestion comes from an external source—the devil, the world, or the memory of past experiences—but this suggestion alone is not yet sin. The devil can present an image or thought to the mind, but the person retains the power to refuse it. However, if the mind takes pleasure in the suggestion, and then consents to act upon that pleasure, sin is committed. Consent is the decisive moment: it is the act of the will that makes the sin fully one’s own.
Augustine then introduces a crucial distinction regarding temptation in the lives of the godly versus the ungodly. For the ungodly, the pleasure itself may be so overwhelming that consent follows almost automatically, as the will is already enslaved to desire. But for the godly, who are under grace, the process is different. The will is now healed enough to resist the initial pleasure, but it is still weak and requires divine assistance to remain steadfast. Augustine writes that even the godly can experience the arousal of pleasure without consenting; this is what he calls concupiscence—the lingering inclination toward sin that remains even after baptism and justification. This concupiscence is not itself sin in the regenerate, but it is the material from which sin arises when consent is given.
CLARIFY: Augustine is clarifying how the sovereignty of grace works in the daily life of the believer. The three-stage model (suggestion, pleasure, consent) shows that sin is not a mechanical inevitability but a moral act requiring the will’s participation. At the same time, Augustine insists that even the ability to resist consent depends on grace, for the healed will is still fragile and must be sustained by God. This sets up the central tension of the Christian life: the believer is no longer under the law’s condemnation, but still struggles with the presence of concupiscence, which can only be fully eradicated in the resurrection.
Book One, Question Three (continued): The Role of the Devil and God’s Permission of Evil
LOCATE: Augustine now deepens the analysis by asking why God permits the devil to tempt human beings, and what this reveals about the divine governance of the will.
PRESENT: The devil, Augustine explains, is a fallen angel who operates only within the limits God sets. The devil cannot compel the human will to consent; he can only suggest. The suggestion itself is a form of external pressure, but the will must internalize it through pleasure and consent for sin to occur. This is why Augustine insists that the devil’s power is derivative: he has no power to create evil ex nihilo, but only to exploit the corrupted inclinations already present in fallen human nature. The devil is essentially the tempter (*tentator*), not the author of sin.
“The devil does not cause sin; he suggests it. The consent to sin is from the will itself.”
Augustine then addresses the deeper theological question: If God is good and sovereign, why does he allow the devil to tempt anyone at all? The answer has two parts. First, temptation serves a pedagogical purpose for the elect: it humbles them, teaches them their dependence on grace, and trains them in virtue. Without the experience of temptation, believers would not know their own weakness and would be prone to pride. Second, the permission of temptation is an act of judgment upon the reprobate: God allows them to be tempted and to fall precisely because he has already abandoned them to their own desires, withholding the grace that would enable them to resist. This is not a failure of love on God’s part, but a manifestation of his justice.
CLARIFY: Augustine is wrestling with the problem of evil in a way consistent with his earlier points about predestination. The devil is not an independent counter-force to God, but a tool within God’s providence, serving both the mercy of the elect and the judgment of the reprobate. The crucial point is that temptation does not occur outside God’s control; it is permitted for definite ends. The elect are tested and strengthened; the reprobate are left to their own devices, which inevitably leads to their condemnation. This is a hard doctrine, but Augustine insists it is the only one that preserves both God’s sovereignty and human responsibility.
Book One, Question Four: The Problem of Human Suffering and the Goodness of God
LOCATE: The fourth question of Book One shifts from the internal dynamics of temptation to the broader problem of suffering in the world, asking how the existence of pain, disease, and disaster can be reconciled with the goodness of a sovereign God.
PRESENT: Augustine begins by acknowledging that the question is an ancient one, raised by pagans and believers alike. He rejects any solution that would limit God’s power or goodness: God is both omnipotent and perfectly good, so suffering must serve some purpose within his providence. Augustine distinguishes between two kinds of evil: sin (*malum culpae*), which is committed by the will, and suffering (*malum poenae*), which is inflicted as punishment. All suffering, he argues, is ultimately a consequence of sin—either the original sin of Adam or the personal sins of individuals. This does not mean that every specific instance of suffering is a direct punishment for a specific sin (Job’s case shows this), but it does mean that suffering exists in the world only because sin has entered it.
Augustine then introduces an important nuance: suffering in this life can also be medicinal. Pain serves to correct the sinner, to restrain the proud, to remind human beings of their mortality, and to purify the faithful. Just as a physician may cause pain to heal a wound, so God uses suffering to cure the soul of its deeper illness—pride and self-reliance. Even the wicked, by experiencing punishment in this life, receive a foretaste of the judgment to come, which may serve as a warning to others.
CLARIFY: Augustine is not offering a theodicy in the modern sense of justifying God before the tribunal of human reason. Instead, he is explaining the logic of divine justice and mercy within a world that has already fallen. Suffering is not a defect in God’s creation but a response to the corruption introduced by sin. For the believer, suffering is a means of sanctification; for the unbeliever, it is a warning and a just penalty. In both cases, God remains good. The key insight is that suffering does not exist in God’s original design but is a consequence of creaturely rebellion, and God redeems even this consequence for his purposes.
Book One, Question Five: The Purpose of the Law and the Weakness of the Will
LOCATE: Augustine now turns to a more detailed examination of the relationship between the law of God and the human will, moving from the general problem of suffering to the specific question of why the law was given if it cannot save.
PRESENT: The question begins with a puzzle drawn from Paul’s epistles: if the law cannot justify, why was it given at all? Augustine presents the law not as a remedy for sin but as a revealer of sin. The law commands what is good—”You shall not covet”—but it does not give the power to obey. Instead, it exposes the depth of human rebellion. Augustine writes that before the law, sin lay dormant; the prohibition stirred up the very desire it forbade. This is the paradox of the law: it is holy and good, yet it provokes transgression. Augustine quotes Paul: “I would not have known sin except through the law” (Romans 7:7). The law thus serves a pedagogical function. It teaches the sinner the true extent of his sickness, driving him to seek a physician. The law is not a ladder to heaven but a mirror that reveals the filth on the face. Augustine clarifies that the law is not evil; rather, it is the flesh—the fallen human nature—that is weak and unable to fulfill what the law commands. The law demands perfection, but the will, enslaved to concupiscence, cannot meet that demand. The result is that the law increases guilt, not because the law is bad, but because the sinner is now without excuse. Before the law, sin was present but not recognized as a direct violation of a clear command; after the law, sin becomes transgression—a deliberate crossing of a known boundary. This heightens both the sin and the punishment. Augustine uses the analogy of a patient who refuses medicine: the doctor’s prescription does not heal the patient but makes the patient’s refusal more culpable. So too, the law prescribes the remedy of obedience, but the will, corrupted by pride, rejects it. The only hope is a grace that not only commands but also enables—a grace that writes the law on the heart, as promised in the prophets.
“The law was given that grace might be sought; grace was given that the law might be fulfilled.”
CLARIFY: This is a crucial move in Augustine’s argument. The law is not an alternative to grace but its necessary precursor. By exposing human inability, the law humbles pride and creates the hunger for grace. The purpose of the law is not to save but to diagnose. Augustine is dismantling any notion that human effort, even in response to divine commands, can achieve righteousness. The law is good, but it cannot fix what is broken; it can only reveal the break. This prepares the reader for Augustine’s full doctrine of grace: salvation comes not through the law but through the Spirit, who enables what the law commands.
Book One, Question Six: The Distinction Between Command and Fulfillment
LOCATE: Augustine moves from the purpose of the law to the mechanics of obedience and disobedience, focusing on the distinction between knowing what is good and actually doing it.
PRESENT: The question opens with a reflection on Paul’s statement in Romans 7:18: “For I know that nothing good dwells in me, that is, in my flesh.” Augustine unpacks this in terms of the will and the power to act. He distinguishes between velle (to will) and posse (to be able). The unregenerate person can will what is good in a general sense—he knows that God should be obeyed—but he lacks the power to actually perform it. This is not merely a matter of weakness but of slavery. The will is divided: one part desires the good, but another part, dominated by concupiscence, drags it downward. Augustine uses the image of a man who wants to stand but is held down by a heavy weight. The weight is the habit of sin, developed over time through repeated choices. This habit becomes a second nature, a bondage that the will cannot break on its own. Augustine insists that the will is free in the sense of being voluntary—no external force compels it—but it is not free in the sense of being able to choose the good without grace. The will has lost its liberty through sin. He quotes Paul: “The good that I will, I do not do; but the evil I will not, that I practice” (Romans 7:19). This is not a description of an unregenerate person merely struggling with temptation; it is a description of the human condition under the law, without grace. The person in this state can see the good, approve of it, and even desire it, but cannot achieve it. The law provides the knowledge; grace provides the power. Augustine stresses that the will is not destroyed by sin—it remains willing—but its willing is misdirected. It wills what is evil because it is captivated by the pleasures of the flesh. The only escape is a delight in the good that outweighs the delight in sin—a delight that is a gift of the Holy Spirit.
“The law commands; grace gives the power to fulfill the command.”
CLARIFY: Augustine is developing a psychology of the will that will become foundational for later Western theology. He rejects any simple Pelagian notion that knowledge is sufficient for obedience. The will is not neutral; it is weighed down by the weight of habit and concupiscence. Knowing the good is not the same as loving the good, and only love—infused by grace—can move the will to action. This distinction between command and fulfillment underscores the absolute necessity of grace for any truly good action. Without grace, the will remains trapped in a cycle of willing and failing, which produces only frustration and guilt.
Book One, Question Seven: The Call of God and the Response of the Will
LOCATE: Augustine now addresses the nature of the divine call that brings a person from bondage to freedom, examining how God’s call works in relation to human will.
PRESENT: The question focuses on the phrase from Romans 8:28: “All things work together for good to those who are called according to his purpose.” Augustine distinguishes between two kinds of calling: the external call that comes through preaching and the internal call that works directly on the heart. The external call can be resisted; many hear the gospel and refuse it. But the internal call is a call that causes the desired response. Augustine calls this the effectual call or vocatio efficax. This call does not merely invite; it draws. It creates in the person both the will and the ability to respond. Augustine compares it to the lure that attracts an animal: just as a piece of meat attracts a dog, so the Holy Spirit presents the soul with a delight in the good that overcomes the delight in sin. This delight is not coercive; it is sweet, and the soul follows it willingly. But the soul would not follow unless it had been given this delight. Augustine quotes John 6:44: “No one can come to me unless the Father who sent me draws him.” The drawing is not by force but by love. The will is not dragged kicking and screaming; it is captivated by a superior beauty. Augustine insists that this does not destroy human freedom; rather, it restores it. Before grace, the will was in bondage; after grace, the will is liberated to choose the good freely. The call of God is therefore the beginning of all salvation. It is not based on any foreseen merit in the person; it is purely a matter of God’s sovereign choice. Some are called and respond; others are not called in this effectual way. Why? Augustine appeals to the hidden wisdom of God, which we cannot fully comprehend but must reverence. The effectual call is an act of mercy; the lack of it is an act of judgment. Both flow from God’s will, which is always just, though not always transparent to human understanding.
“The grace of God not only offers righteousness to the unwilling but also makes the unwilling willing.”
CLARIFY: This is a pivotal section for understanding Augustine’s doctrine of predestination. The effectual call is not merely an invitation that can be accepted or rejected by a neutral will. It is a creative act of God that transforms the will itself. The will remains free—it follows what it loves—but God determines what the will loves by giving the gift of delight. This is not compulsion but conversion: a change in the heart’s deepest orientation. Augustine is careful to preserve human responsibility—the person who responds does so willingly—while affirming that the response itself is a gift. This sets the stage for the later controversies between Augustinian and semi-Pelagian views of grace.
Book One, Question Eight: The Distinction Between the Letter and the Spirit
LOCATE: We have moved through seven questions exploring the law, the will, grace, suffering, temptation, and the divine call, and now Augustine turns to Question Eight, which examines Paul’s distinction between the letter and the spirit in 2 Corinthians 3:6—”the letter kills, but the spirit gives life.”
PRESENT: Augustine opens this question by acknowledging that this Pauline statement has been the source of considerable confusion among readers. The apostle writes, “Who also has made us competent ministers of the new covenant, not of the letter but of the spirit; for the letter kills, but the spirit gives life.” Augustine insists that Paul is not speaking about two different kinds of biblical interpretation—as some have suggested—but about two different relationships to the law of God. The “letter” refers to the law as a written commandment that demands obedience without supplying the power to obey. The “spirit” refers to the grace of the Holy Spirit that enables the fulfillment of the law. The letter kills because it commands what human beings cannot do on their own, thereby exposing their sin and bringing condemnation. The spirit gives life because it heals the will and empowers the soul to love what God commands.
Augustine draws on the apostle’s own argument in Romans 7, which he has already discussed at length. Paul describes the experience of someone under the law but without grace: “I delight in the law of God according to the inward man, but I see another law in my members, warring against the law of my mind and bringing me into captivity to the law of sin” (Romans 7:22-23). This is the condition of the person who has the letter but not the spirit—who knows what God requires but lacks the love that makes obedience joyful and possible. The letter commands, but it does not heal. It reveals the disease of sin but does not provide the medicine of grace. The spirit, by contrast, is the gift of the Holy Spirit who pours the love of God into the heart (Romans 5:5), transforming the will so that what the law commands becomes the object of genuine desire.
“The letter, therefore, which commands, is useful for showing the wound, but it does not heal it; indeed, it kills, because it increases the desire for sin, unless grace comes to the aid of the soul.”
Augustine then considers the relationship between the Old and New Covenants. The Old Covenant was written on stone tablets—the literal letter of the law. The New Covenant is written on the hearts of believers by the Holy Spirit. This is the prophecy of Jeremiah 31:33, which Augustine quotes: “I will put my law within them, and I will write it on their hearts.” The difference is not that the moral content changes—the same commandments remain—but that the mode of obedience is transformed. Under the Old Covenant, obedience was external, motivated by fear of punishment. Under the New Covenant, obedience is internal, motivated by love and delight in righteousness. The spirit gives life precisely because it produces this inner transformation, making the law not an external burden but an internal principle of joy.
CLARIFY: This question provides the theological foundation for Augustine’s entire understanding of grace and law. The letter-spirit distinction is not about allegorical versus literal interpretation, as some later readers would claim, but about the difference between a law that demands and a grace that enables. The letter kills because it commands the impossible without a transformed will. The spirit gives life because it provides both the desire and the power to fulfill what God commands. This directly connects to Augustine’s earlier arguments about the will’s bondage and the necessity of grace. The person who has only the letter is like the person in Romans 7 who wills the good but cannot perform it. The person who receives the spirit is like the person in Romans 8 who walks according to the Spirit and fulfills the righteousness of the law.
Book One, Question Eight (continued): The Spirit and the Freedom of the Will
LOCATE: Augustine continues his exploration of the letter-spirit distinction by examining how the spirit actually operates in the human soul to produce genuine freedom and obedience.
PRESENT: Augustine argues that the spirit does not abolish the law but fulfills it, and it does so by giving the soul a new principle of action. The key concept here is delight or pleasure (*delectatio*). Earlier, Augustine had described how the will is moved by what delights it most. Now he applies this directly to the work of the Holy Spirit. The spirit gives life by infusing a new delight in righteousness, a love for what God commands, so that the soul no longer obeys reluctantly but willingly and joyfully. The law written on the heart is not a new set of external regulations but a new disposition of the heart that spontaneously loves what the law commands.
Augustine draws an important distinction between fear and love. He observes that someone can obey the law out of fear of punishment, but this is not the obedience that pleases God. The apostle John writes, “There is no fear in love, but perfect love casts out fear, because fear involves punishment” (1 John 4:18). The obedience that comes from fear is servile and external; the obedience that comes from love is filial and free. The spirit produces this filial love, making believers sons and daughters who obey not because they must but because they want to. This is what Paul means when he says, “You have received the spirit of adoption as sons, by which we cry, ‘Abba! Father!'” (Romans 8:15). The spirit transforms the very motivation of obedience.
Augustine then considers an objection: If the spirit makes obedience joyful and spontaneous, does this mean that believers never struggle with sin? He answers by pointing to the ongoing battle between the flesh and the spirit described in Galatians 5. Even after receiving the spirit, believers continue to experience resistance from the flesh—the old habits and desires that remain from their former life. The spirit gives life, but this life is progressive, not instantaneous. The believer must continue to “walk by the Spirit” and “not gratify the desires of the flesh” (Galatians 5:16). The difference from the person under the law alone is that the believer now has an internal resource—the Spirit’s power and the new delight in righteousness—to resist sin and grow in holiness.
“This life, then, which the spirit gives, is that by which we are made to love what the law commands and to fulfill the law with the freedom of those who delight in it, not with the servitude of those who fear it.”
Augustine concludes by emphasizing that the spirit is not a reward for human effort but a gift of divine grace. The letter-spirit distinction is not merely a description of two historical eras (Old Covenant versus New Covenant) but of two conditions of the human soul. Even in the Old Testament, there were believers who received the spirit and obeyed from love—Abraham, David, the prophets. And even in the New Testament, there are those who have the external letter of the gospel but lack the internal spirit—those who profess Christ but do not truly love him. The decisive factor is not the age in which one lives but the presence or absence of the Holy Spirit’s transforming work in the heart.
CLARIFY: This section deepens Augustine’s psychology of grace. The spirit does not merely give information or external help; it transforms the very springs of action by giving a new delight. This is the fulfillment of Augustine’s earlier argument that the will is determined by what it loves. The spirit changes what the will loves, and therefore the will freely and spontaneously moves toward obedience. This is why Augustine can speak of the spirit giving “freedom”—not freedom from constraint (which the will never has) but freedom from the bondage of sin, which is the compulsion to love the wrong things. The struggle with the flesh remains, but the spirit provides both the desire and the power to overcome it, making obedience not merely possible but gradually more joyful and natural.
Book One, Question Nine: The Distinction Between the Law of Works and the Law of Faith
LOCATE: In Question Nine, Augustine continues his Pauline exegesis by examining the distinction Paul draws in Romans 3:27 between “the law of works” and “the law of faith,” and how this distinction relates to justification and boasting.
PRESENT: Augustine begins by quoting Paul: “Where, then, is boasting? It is excluded. By what law? Of works? No, but by the law of faith” (Romans 3:27). He notes that some readers have misunderstood this passage, thinking that Paul is contrasting two different systems of salvation—one based on works and one based on faith. But Augustine insists that the distinction is more nuanced. The “law of works” does not refer to the moral law itself—which is good and holy—but to a particular way of relating to the law. The law of works is the law as it operates when one tries to fulfill it by one’s own strength, apart from grace. This law produces either pride (if one thinks one has succeeded) or despair (if one realizes one has failed). Either way, it leads to boasting—if not in actual achievement, then in the self-righteousness that comes from comparing oneself to others.
The “law of faith,” by contrast, is the law as it operates when one recognizes one’s inability to fulfill it and casts oneself on God’s mercy. The law of faith does not abolish the law but fulfills it through Christ. Paul writes, “Do we then overthrow the law by this faith? By no means! On the contrary, we uphold the law” (Romans 3:31). The law of faith upholds the law by acknowledging that the law’s demands are just and that we cannot meet them on our own, thus driving us to seek the grace that Christ provides. The law of works says, “Do this and you shall live.” The law of faith says, “Believe in the one who has done it for you, and you shall live.”
“The law of works, therefore, is that which threatens punishment and commands works; the law of faith is that which asks for mercy and grants forgiveness.”
Augustine then explores the term “boasting” (*gloriatio*) more deeply. He argues that all human boasting is excluded by the law of faith because it humbles the soul before God. The person who tries to establish his own righteousness through works of the law inevitably boasts—if not openly, then secretly in his heart. The person who receives righteousness by faith has nothing to boast about, because everything is a gift. This is what Paul means when he writes, “For by grace you have been saved through faith, and that not of yourselves, it is the gift of God, not of works, so that no one may boast” (Ephesians 2:8-9). The law of faith humbles the proud and exalts the humble, because it teaches that salvation is entirely from God’s mercy, not from human achievement.
Augustine also addresses the relationship between faith and works. The law of faith does not mean that works are unnecessary, but that works follow from faith rather than preceding it. Faith is the root, works are the fruit. The law of faith produces good works by first giving the grace that makes them possible. The law of works commands good works without giving the power to perform them. The difference is not in the content of the works but in their source and motivation. The works done through the law of faith are done in love and gratitude, not in fear and self-assertion.
CLARIFY: This question directly anticipates the Reformation debates about justification by faith alone, though Augustine’s formulation is more nuanced than later polemics would suggest. The key insight is that the “law of works” is not the moral law as such but a particular posture toward it—the attempt to establish one’s own righteousness through self-effort. The “law of faith” is not a different set of commands but a different way of relating to God’s commands—through humble trust in Christ’s righteousness and the Spirit’s enabling power. Augustine thus preserves both the goodness of the law and the necessity of grace, while excluding all human boasting. This is entirely consistent with his earlier arguments about the will’s bondage and the gift of delight.
Book One, Question Ten: The Calling of God and the Purpose of Election
LOCATE: In the tenth and final question of Book One, Augustine returns to the theme of divine calling and election, now focusing on how God’s call relates to the purpose of election and the fulfillment of God’s eternal plan.
PRESENT: Augustine begins by examining Paul’s statement in Romans 8:28: “And we know that for those who love God all things work together for good, for those who are called according to his purpose.” He notes the precision of Paul’s language: not simply “those who are called” but “those who are called according to his purpose.” This distinction, Augustine argues, points to the difference between the general call and the effectual call. Many are called in the general sense—the gospel is preached to them, they hear the invitation—but only those who are called according to God’s purpose respond with faith and love. The general call can be resisted; the effectual call cannot, because it is accompanied by the gift of grace that makes the will willing.
Augustine then explores the meaning of purpose (*propositum*) in this context. He argues that God’s purpose is not something that can be thwarted or frustrated by human resistance. What God purposes, he accomplishes. This purpose is eternal, predestined before the foundation of the world. Paul writes, “For those whom he foreknew he also predestined to be conformed to the image of his Son” (Romans 8:29). Foreknowledge here does not mean simply knowing in advance what humans will freely choose. It means God’s loving, electing knowledge—the knowledge that chooses and sets apart. This is the same kind of knowledge Paul describes when he says of Jacob, “Jacob I loved, but Esau I hated” (Romans 9:13). God’s foreknowledge is not passive observation but active election.
Augustine also considers the relationship between calling and perseverance. He argues that those who are called according to God’s purpose not only respond to the call initially but also persevere to the end. This is because the call itself contains the gift of perseverance. Paul writes, “He who calls you is faithful; he will surely do it” (1 Thessalonians 5:24). The same God who initiates the work of grace in the soul also sustains it and brings it to completion. Augustine draws on Philippians 1:6: “He who began a good work in you will carry it on to completion until the day of Christ Jesus.” The effectual call is the beginning of a process that God himself guarantees will reach its intended end.
“Those who are called according to the purpose, therefore, are those who have been chosen in Christ before the foundation of the world, and who are not only called but also justified and glorified through the grace of God.”
Augustine concludes Book One by emphasizing the security of the elect. Those who are called according to God’s purpose can have confidence that God will complete what he has started. This is not a confidence that leads to carelessness or presumption—Augustine insists that the elect must continue to pray, to struggle, to grow in holiness—but it is a confidence that rests on God’s faithfulness rather than human effort. The purpose of God is immutable, and those whom God has chosen will certainly be saved. This is the ultimate comfort for believers who are aware of their own weakness and the temptations that surround them.
CLARIFY: This final question of Book One brings Augustine’s theology of grace to its logical conclusion. The effectual call is rooted in God’s eternal purpose, which cannot fail. This is the beginning of Augustine’s mature doctrine of predestination, which would become so controversial in later centuries. The purpose of God is not conditional on human response; rather, human response is itself the result of God’s purpose. The effectual call creates the faith it requires, ensures the perseverance it promises, and guarantees the glorification it foretells. Yet Augustine never allows this to slide into fatalism. The call is still a call—it addresses human beings as responsible agents, it requires their response, and it leads to a life of active faith and obedience. The mystery is that God’s sovereign purpose and human responsibility are both real, though their ultimate harmonization lies beyond human comprehension.
