Grace

← Encyclopedia

Grace, in Christian theology, is the unearned favor of God toward human beings — help and acceptance given as a gift rather than as wages owed for anything done to deserve them. The Greek word behind it, charis, carries the ordinary senses of favor, kindness, and gift; in the letters of Paul the Apostle it becomes a technical term for the way God acts toward people who, on the doctrine’s own telling, have no claim on him. From the start the idea defines itself against an alternative it rejects: that a person might earn standing before God by merit. Paul sets the two side by side as exclusive accounts of how a human being comes to stand right with God — if it is by grace, it is no longer of works, and if of works, grace is no longer grace. The whole later history of the concept is an attempt to hold that exclusion without making the human being a stone.

A word that became a doctrine

Before Paul, charis was an unremarkable word of Greek social life: the graciousness of a host, the gift exchanged between friends, the kindness shown to one who could not repay. The Hebrew scriptures had their own vocabulary for the same reality — ḥen, favor found in the eyes of another, and ḥesed, the steadfast loyal love by which God keeps covenant with a people who break it. The Septuagint, the Greek translation of the Hebrew scriptures, often rendered both with charis, and Paul inherited the word already weighted with that covenantal sense. What he did was sharpen it into a near-technical term for a single movement: God turning toward the undeserving first, before and without any qualifying act on their side. In the Letter to the Romans the argument is relentless — Abraham was reckoned righteous by faith and not by works, so that the promise might rest on grace; where sin increased, grace abounded all the more. The word ceases to describe an attitude and begins to name the structure of salvation itself.

The early Greek-speaking church kept charis close to its scriptural register, often hearing in it the deifying gift by which the human being is drawn into the divine life — the strand that later Eastern theology would develop as a doctrine of participation. The decisive technical pressure came in the Latin West, where gratia and the sharp Roman vocabulary of merit, debt, and law gave the grace-against-works question an edge it never quite lost.

Augustine and Pelagius

The fault line that runs through the history of the concept opened in the early fifth century, in the dispute between Augustine of Hippo and the monk Pelagius, traditionally said to be British. Pelagius, an ascetic teacher active at Rome in the years around 410, held that human beings could, by free will and effort, keep God’s commands and so play a real part in their own salvation; to say otherwise, he reasoned, was to excuse moral laziness and to make God unjust for commanding what cannot be done. Augustine answered that the will itself is wounded — turned in on itself by the inherited fault of the first human refusal — and cannot turn toward God unless grace moves it first. Grace, on his account, does not merely assist a will already inclined to the good; it heals, frees, and inclines the will, working in the person so that they will and do what is right. He pressed the point to its limit: even the first stirring of faith, the initial turning, is itself a gift, and God’s choice of whom to draw is eternal and unmerited.

The Church sided with Augustine. A synod at Carthage in 418 condemned the Pelagian positions, and Pelagius and his abler follower Caelestius were excommunicated; the second Council of Orange in 529 ratified an Augustinian account of grace as prior to every human good act while stopping short of his harshest teaching on predestination. A middle party — later labeled Semipelagian, gathered around the monasteries of southern Gaul and articulated by John Cassian — had argued that grace and the will cooperate from the start, the human being making the first small movement of assent that grace then completes; Orange rejected even that concession to a self-started faith. The questions Augustine’s answer raised never closed. If grace alone saves, what remains of human freedom? If God chooses whom to save, what of those not chosen? These are the twin debates — grace against works, grace against free will — that recur in every later century.

The medieval system

Medieval theology built grace into a system of sacraments, the channels through which it was held to be conveyed, and refined the single word into a working vocabulary. It distinguished the grace that first turns a person toward God — prevenient or operating grace, which goes before any movement of the will — from the cooperating grace that sustains and perfects the turning once begun. It separated actual grace, the transient divine help given for a particular act, from habitual or sanctifying grace, a settled quality infused into the soul that makes the person genuinely pleasing to God and a sharer in the divine life. The sacraments were understood to confer this latter grace by the working of the rite itself, ex opere operato, so that grace became something the visible Church administered rather than only an invisible favor.

Thomas Aquinas gave the architecture its most exact form in the treatise on grace in the Summa Theologiae (the questions of the Prima Secundae, roughly 109 through 114). Drawing Aristotle’s metaphysics into Augustine’s theology, he defined sanctifying grace as a created supernatural quality, an elevation of the soul above its own nature, and worked out the order in which grace and free will act: God moves the will, yet moves it precisely as a will, so that the free assent is genuinely the person’s own act and genuinely caused by grace. Merit returns, but only inside grace — the justified can merit further grace and reward, yet the first grace, the one that begins the whole movement, can never be merited, since to earn it one would already need it. The account is at once thoroughly Augustinian on the priority of the gift and carefully protective of a real, secondary human cooperation. That balance held the medieval West together; the Reformation broke it.

Sola gratia: the Reformation

The Reformation broke hard on this point. Martin Luther, an Augustinian friar tormented by the demand that he love a God who judged him, found his release in Paul’s Letter to the Romans: the righteousness God requires is the righteousness God himself gives, received by faith and not produced by the sinner. From this came sola gratia — by grace alone — and its companion sola fide, by faith alone: salvation is wholly God’s act, the sinner declared righteous on Christ’s account rather than made righteous by infused quality and accumulated merit. Luther fixed the issue in his clash with Erasmus, who had defended a modest freedom of the will to turn toward or away from grace; Luther’s reply, On the Bondage of the Will (1525), insisted with Augustine that the unredeemed will is in bondage and cannot will its own rescue. The medieval machinery of merit and the sacrament-administered treasury of grace he rejected as a transaction that turned the gift back into wages.

John Calvin gave the Reformation account its most systematic form. In the Institutes of the Christian Religion he traced every stage of salvation to God’s free decision and pressed the logic to election and predestination — the teaching that God has eternally chosen the saved, and (in the form Calvin did not flinch from) passed over the rest. Grace here is particular and effectual: it does not offer itself to all and wait, but actually accomplishes in the elect the turning it intends. The Reformed tradition that followed compressed this into the doctrine that fallen humanity is wholly unable, that election is unconditional, and that the grace which calls the elect is not finally resisted.

Trent and the Arminian recovery

The Catholic response came at the Council of Trent, whose long Decree on Justification (1547) affirmed grace as primary while holding that the justified genuinely cooperate with it. Trent taught that the whole movement begins with prevenient grace, freely given and in no way merited, which awakens and assists a will that then freely assents; it condemned both the view that a person can be justified by their own works apart from grace and the view that human freedom plays no part at all once grace has touched it. Justification, on this account, is not merely a declaration but a real renewal, grace infused so that the person becomes righteous, with the cooperation of a will that grace has set free. Against the Reformers it preserved merit within grace and the sacramental economy; against any Pelagian reading it made the first grace pure gift.

Within Protestantism itself a counter-current soon recovered a wider human freedom. Jacobus Arminius, a Dutch Reformed theologian, and the Remonstrants who carried his teaching forward after his death set out five articles in 1610: grace is the beginning, continuance, and completion of every good, so that nothing good is done without it — but the grace that calls is resistible, and the human being may finally refuse what is offered. The Synod of Dort (1618–1619) condemned the Remonstrance and reasserted an uncompromising Reformed account, but the Arminian position survived and spread, shaping later Methodism and much of evangelical Protestantism. Each of these settlements reads the same scriptures and reaches a different conclusion; the disagreements are precise, not loose, and they remain live.

The efficacious-grace quarrels

The Augustinian fault did not close with the Reformation; it reopened inside Catholicism over the exact mechanics by which grace and the will meet. Late in the sixteenth century the Jesuit Luis de Molina proposed that God offers sufficient grace to all, which becomes efficacious — actually fruitful — only when the free will consents, God foreknowing through a special knowledge how each will would freely respond; the Dominican Thomists, led by Domingo Báñez, answered that efficacious grace moves the will intrinsically and infallibly to its consent, lest the decisive factor be the human choice rather than God’s gift. The dispute grew so heated that Rome convened a special commission, the Congregatio de Auxiliis (1598–1607), to adjudicate it; the commission ended without a verdict, forbidding each side to brand the other heretical, and the question of how grace can be wholly God’s and the consent wholly free was left standing.

It returned in fiercer form with the Jansenists, who read Augustine against the Jesuit accommodations and held that the grace which truly saves is efficacious of itself, irresistibly drawing the will it touches — a position the papacy condemned across the seventeenth century. Blaise Pascal, drawn into the controversy through the convent of Port-Royal, defended the Augustinian-Jansenist account against what he saw as a Jesuit moral laxism that made grace cheap and salvation easy; his Provincial Letters (1656–1657), written under a pseudonym, turned the technical quarrel over sufficient and efficacious grace into a public scandal and a landmark of French prose. Pascal’s own writing carries the doctrine into the register of experience: in the parchment he sewed into his coat after the night of fire of November 1654, and in the unfinished apology gathered as the Pensées, the God who is found is the one who first seeks — a person could not look for him, in the famous figure, who had not already been found by him.

Grace as experience: quietism and the inner life

Where grace is held to be wholly God’s act, a recurring temptation follows: that the right human posture is not effort but cessation — to stop acting and let grace work. This is the impulse that runs through Christian contemplation and that came to a crisis in quietism, the late seventeenth-century movement that prized a radically passive interior prayer and a “pure love” so disinterested that it would consent even to its own loss. Madame Guyon, the French laywoman whose Short and Easy Method of Prayer (1685) democratized this contemplative path, taught a state in which the soul, sensing God taking possession of it, ceases its own acts and rests in total abandonment. The French Church, through the Conferences of Issy and the condemnation of the work that her defender François Fénelon wrote on her behalf, judged that this pressed the priority of grace into the suppression of the will and the sacraments themselves, and quietism was condemned — even as its abandon-mysticism crossed confessional lines to shape Protestant Pietism and later evangelical devotion.

Beneath the technical quarrels lies a single intuition that the traditions share even where they divide over its mechanics: that the decisive movement in salvation comes from God’s side, not the human one. Across the divisions, grace has been spoken of less as a doctrine than as a thing undergone — of being met, forgiven, or lifted beyond one’s own capacity. The contemplative tradition mapped in Christian mysticism describes the same gift in the language of union, and the older current of gnosis traced a turning that the self cannot initiate from within itself — kindred grammars of an unearned change, each set within its own cosmology and meaning something exact there. Christian grace is bound tightly to a particular story: the disordered will and inherited fault named as sin, the divine descent into a human life, and the reconciliation worked through the cross — the architecture of Christianity itself.

That binding has been part of the doctrine’s identity since the second century, when Marcion of Sinope pushed the logic of grace to a breaking point, opposing the gracious God of the gospel to the just God of the law so sharply that he severed them into two deities and cut the Hebrew scriptures away — a reading the Church rejected precisely to keep grace and judgment, the gift and the law, within one God and one story.

Scholarship and primary sources

The standard modern history of the doctrine in its narrower form — justification, the act in which grace makes a sinner righteous — is Alister McGrath’s Iustitia Dei: A History of the Christian Doctrine of Justification, whose substantially rewritten fourth edition (Cambridge University Press, 2020) reaches from the Hebrew and Greek semantic background through the medieval and Reformation settlements; McGrath’s Christian Theology: An Introduction gives the doctrinal map in survey. The primary texts are largely public and largely available. Augustine’s anti-Pelagian treatises — On Nature and Grace, On the Spirit and the Letter, On the Predestination of the Saints — survive in the nineteenth-century Nicene and Post-Nicene Fathers translations; the philosophical setting of his thought on grace and the will is mapped in the Stanford Encyclopedia of Philosophy entry on Augustine. Aquinas’s treatise on grace is online in the English Dominican translation at Question 109 of the Prima Secundae, where the questions on the necessity, essence, division, and cause of grace run in sequence. For the Reformation, Calvin’s Institutes of the Christian Religion (Books II and III, on the bondage of the will and on the mode of receiving Christ’s grace) is hosted complete in the Beveridge translation; Luther’s On the Bondage of the Will answers Erasmus directly. The confessional settlements that fixed the modern divisions are gathered in Philip Schaff’s Creeds of Christendom, whose third volume sets the Remonstrance and the Canons of Dort side by side; the Catholic settlement is the Tridentine Decree on Justification of Session VI (1547). The contemplative reception of grace as an experience to be undergone rather than a doctrine to be parsed is read in the anonymous fourteenth-century Cloud of Unknowing.

What the word finally names is a refusal to make the relation to the divine a transaction — the claim that the gift comes first.
