Christian Classics
The greatest Christian books of all time. From the early church fathers to the Puritans and beyond, these works have shaped Christian thought and devotion across the centuries.
Early Church
5 of 5 availableThe Didache
Anonymous
TreatiseThe earliest Christian manual outside the New Testament, probably written in the first or early second century. Covers ethics, baptism, fasting, prayer, the Eucharist, and church leadership in plain, direct language.
The Letters of Ignatius of Antioch
Ignatius of Antioch
TreatiseSeven letters written by Ignatius, bishop of Antioch, as he traveled under guard to his martyrdom in Rome around 107 AD. Each addresses a different congregation or person, urging unity with the bishop, refuting heresies that denied Christ truly suffered in the flesh, and expressing Ignatius's own longing to die for Christ. Written within two generations of the apostles, the letters contain the earliest known use of the phrase 'the Catholic Church' and remain the clearest early witness to episcopal structure as the norm of Christian life.
The First Apology
Justin Martyr
TreatiseWritten around 155 AD and addressed to Emperor Antoninus Pius, this defense of Christianity is the earliest surviving detailed account of what Christians believed and how they worshiped. Justin argues that Christians are loyal citizens who deserve legal protection, drawing on philosophy, prophecy, and comparison with pagan religion to make his case. It contains the first written description of Sunday worship and baptism, making it one of the most important documents from the second-century church.
On the Incarnation
Athanasius of Alexandria
TreatiseThe definitive early Christian defense of why the eternal Son of God became a human being and why his death and resurrection were necessary. C.S. Lewis called it one of the greatest works in Christian theology and wrote the introduction to its modern translation.
Confessions
Augustine of Hippo
AutobiographyAugustine's spiritual autobiography traces his long journey from ambition and restlessness to faith, addressed directly to God in prayer. It gave the Western church both its most personal theological voice and its most searching account of what it means to be human.
Medieval
1 of 3 availableOn Loving God
Bernard of Clairvaux
TreatiseA brief and luminous treatise on why and how we should love God, tracing the soul's ascent through four degrees of love. Bernard writes with warmth and precision, grounding mystical language in solid theological reasoning.
Proslogion
Anselm of Canterbury
TreatiseWritten as a prayer addressed to God, the Proslogion argues from the concept of a being than which nothing greater can be conceived to the conclusion that God exists necessarily and possesses every perfection. The argument has occupied philosophers for nearly a thousand years, but Anselm wrote it as an act of faith seeking understanding rather than a formal proof, and the sustained meditation on God's goodness, justice, and mercy that follows the opening argument is the heart of the work. Written at Bec in 1077, it is the most concentrated reflection on the divine attributes in the medieval tradition.
Coming soonCur Deus Homo
Anselm of Canterbury
TreatiseAnselm's dialogue on atonement argues that human sin creates an infinite debt that only God can pay but only humanity owes, and that the incarnation and death of the God-man was therefore not arbitrary but logically necessary. Written around 1097 at Bec, it is the foundational work on the doctrine of satisfaction in Christian theology: the Reformers drew on its framework directly, and the Westminster divines worked within the assumptions Anselm first articulated. The dialogue form gives the argument unusual clarity, with Anselm walking his interlocutor Boso through each step of the problem and its resolution.
Coming soonReformation
11 of 14 availableInstitutes of the Christian Religion
Calvin's four-volume systematic theology, the defining text of Reformed doctrine. Moving from the knowledge of God and humanity, through Christ and salvation, to the church and its sacraments.
Institutes of the Christian Religion: Book One

TreatiseThree Forms of Unity
The confessional standards of Continental Reformed churches: the Belgic Confession, the Heidelberg Catechism, and the Canons of Dort.
Westminster Standards
The confessional documents produced by the Westminster Assembly from 1643 to 1649, defining Reformed doctrine, worship, and church governance for Presbyterian and Reformed churches worldwide.
The Freedom of a Christian
Martin Luther
TreatiseLuther's most readable exposition of the Reformation's central insight: that the Christian is at once completely free through faith and completely bound in loving service to the neighbor. A short essay that captures the heart of the gospel.
The Bondage of the Will
Martin Luther
TreatiseLuther's most rigorous theological work, written in response to Erasmus on the freedom of the will. Luther argues that without God's grace the human will is bound in sin and incapable of turning to God. Luther himself considered it the most important work he ever wrote.
The Obedience of a Christian Man
William Tyndale
TreatiseTyndale's bold argument that every Christian owes obedience first to God's Word and then to earthly rulers, written in exile. A defense of Scripture in the vernacular, a rebuke of corrupt clergy, and a direct appeal to the king to reform the English church.
The Small Catechism
Martin Luther
CatechismWritten for ordinary Christians and their households, Luther's Small Catechism teaches the Ten Commandments, the Apostles' Creed, the Lord's Prayer, and the two sacraments in plain question and answer form. Simple, direct, and profound, it has shaped Christian formation across Protestant traditions for five centuries.
Puritan
11 of 22 availableThe Bruised Reed
Richard Sibbes
TreatiseA tender and searching meditation on Christ's promise not to break the bruised reed nor quench the smoking flax. Sibbes draws out the compassion of Christ for weak, doubting, and afflicted believers with pastoral warmth that has brought comfort across four centuries.
The Rare Jewel of Christian Contentment
Jeremiah Burroughs
TreatiseDrawn from Philippians 4:11, this treatise argues that contentment is not passive resignation but a learned grace: an active inward disposition that comes from knowing God, knowing oneself, and drawing on the sufficiency of Christ. Burroughs delivered these sermons to his London congregation during the upheaval of the English Civil War, and the book was published posthumously in 1648. Among Puritan works on the inner life, it is distinguished by pastoral warmth and precise application.
Precious Remedies Against Satan's Devices
Thomas Brooks
TreatiseThomas Brooks catalogues the specific tactics Satan uses against the soul and pairs each with remedies drawn from scripture, written with the pastoral heat of a London Puritan minister who believed spiritual warfare was the daily reality of every Christian. First published in 1652 and dedicated to the Parliament of England, the book went through multiple editions in Brooks' own lifetime and has been reprinted in every century since. Brooks writes not for the scholar but for the congregant, matching each device not with abstract doctrine but with concrete, applicable counsel.
Of the Mortification of Sin in Believers
John Owen
TreatiseOwen's treatise on Romans 8:13 lays out the Puritan case for the ongoing mortification of sin as the vital work of every believer. Written in 1656 at the height of Puritan pastoral theology, it argues that only the Holy Spirit can accomplish true mortification, and proceeds through fourteen chapters of searching diagnosis and practical direction. Few works have shaped the Reformed understanding of sanctification more deeply across four centuries.
The Reformed Pastor
Richard Baxter
TreatiseA pastoral treatise written during Baxter's ministry at Kidderminster and based on his program of systematic personal instruction across every household in his parish. Baxter presses two arguments: ministers must first be genuinely converted and spiritually alive themselves before they can rightly shepherd others, and Sunday preaching is not enough without the direct personal examination and instruction of every soul in their care. The book has shaped Reformed ideals of the pastoral office for nearly four centuries.
A Call to the Unconverted
Richard Baxter
SermonBaxter's urgent appeal to the unconverted, originally a series of sermons. Direct, warm, and relentless in pressing the claims of the gospel on those outside of Christ. It reportedly led to hundreds of conversions and remained in print for three centuries.
All Things for Good
Thomas Watson
TreatiseWritten in 1663, the year after Watson and two thousand other Puritan ministers were ejected from their pulpits by the Act of Uniformity, this treatise on Romans 8:28 is the theology of a man who had just lost everything and still believed God works all things for good. Watson moves through eight tightly argued chapters, from the certainty of the privilege to the doctrine of election, showing why both the best and the worst things in a believer's life serve their eternal good. It remains one of the clearest and most pastoral expositions of divine providence in the English tradition.
Grace Abounding to the Chief of Sinners
John Bunyan
AutobiographyBunyan's spiritual autobiography, written in prison, recounts his years of spiritual terror and eventual peace through the gospel. Raw, honest, and theologically serious, it reads like a spiritual companion to Augustine's Confessions.
Keeping the Heart
John Flavel
TreatiseA short, direct pastoral treatise on guarding the inner life based on Proverbs 4:23. Flavel examines the times and conditions in which the heart is most at risk, and gives practical counsel for each season of life.
The Pilgrim's Progress
John Bunyan
AllegoryThe greatest allegory in Christian literature, following Christian's journey from the City of Destruction to the Celestial City through trials, companions, and temptations. After the Bible, it was the most widely read book in English for two centuries.
Sinners in the Hands of an Angry God
Jonathan Edwards
SermonThe most famous sermon in American history, preached at the height of the Great Awakening. Edwards uses the image of God holding the sinner over the pit of hell to drive home the urgency of repentance, but the sermon ends with the offer of mercy.
The Art of Prophesying
William Perkins
TreatiseThe foundational Puritan manual on preaching. Perkins lays out a Reformed theology of Scripture, principles of biblical interpretation, and a method of sermon construction that shaped the entire generation of preachers who built Puritanism. Compact and direct, it remains one of the most influential books on preaching ever written.
Coming soonPrayer
John Bunyan
DevotionalA practical guide to the nature and practice of prayer, drawn from Bunyan's own spiritual struggle and Scripture. Bunyan defines true prayer, explains why believers find it difficult, and shows how the Holy Spirit carries the soul into genuine communion with God. Simple, honest, and deeply encouraging.
Coming soonThe Godly Man's Picture
Thomas Watson
TreatiseA systematic portrait of the Christian character, drawn entirely from Scripture. Watson works through the distinguishing marks of genuine saving grace, making it an invaluable guide for self-examination and one of the clearest practical theologies of the Christian life in the Puritan tradition.
Coming soonThe Doctrine of Repentance
Thomas Watson
TreatiseA thorough and searching treatment of true repentance. Watson identifies the essential ingredients of genuine repentance and exposes the counterfeits that leave the soul unchanged, insisting throughout that repentance is not a single act but a lifelong posture of the heart.
Coming soonA Sure Guide to Heaven
Joseph Alleine
TreatiseOne of the most searching evangelistic books ever written, originally published as An Alarm to the Unconverted. Alleine examines the marks of an unconverted soul with unusual precision and then pleads for immediate response with the force and tenderness of a man who knows the weight of eternity.
Coming soonFacing Grief
John Flavel
DevotionalWritten originally to comfort parents who had lost children, this is one of the most tender books in the Puritan library. Flavel draws on deep personal loss and Scripture to meet those crushed by sorrow, pointing them to Christ as the only true consoler and the only one who can redeem grief.
Coming soonThe Mystery of Providence
John Flavel
DevotionalA rich meditation on how God's particular providence works in every area of the believer's life. Based on Psalm 57:2, Flavel teaches the Christian to read God's hand in ordinary events and sustains the soul under hardship with the conviction that nothing happens outside the Father's careful design.
Coming soonA Body of Divinity
Thomas Watson
TreatiseWatson's sermons on the Westminster Shorter Catechism, delivered to his London congregation and organized by doctrine, make up the most accessible systematic theology produced by any Puritan divine. Watson moves through all 107 catechism questions with characteristic clarity, warmth, and illustrative application, covering the nature of God, the covenants, Christ, justification, sanctification, and the sacraments. Published posthumously in 1692, a decade after Watson was ejected from his pulpit by the Act of Uniformity, it remains the most practical introduction to Reformed doctrine in the English language.
Coming soonA Divine and Supernatural Light
Jonathan Edwards
SermonEdwards draws a sharp line between natural knowledge about God and the saving knowledge given by the Spirit: the first can be achieved by study and reason, the second only by divine illumination acting directly on the soul. Preached in Northampton in 1733, the sermon is one of Edwards' most precise theological statements and the doctrinal foundation beneath his Great Awakening preaching. It remains the clearest Reformed account of how regeneration transforms the quality, not merely the quantity, of what a person knows about God.
Coming soonThe Excellency of Christ
Jonathan Edwards
SermonEdwards meditates on the union of infinite divine majesty and gentle human meekness in the single person of Christ, asking what it means that the same being holds together qualities reason says cannot coexist. Preached in 1736 and published two years later, the sermon gave the Great Awakening a Christological center that extended beyond fear and conviction to wonder and adoration. It is frequently read as the most devotionally rich of Edwards' short works.
Coming soonHeaven Is a World of Love
Jonathan Edwards
SermonThe final sermon in Edwards' series of fifteen on 1 Corinthians 13, this piece describes heaven not as abstract bliss but as a society ordered entirely by love, where every relationship reflects the eternal love within the Trinity. Preached in 1738 and not published until 1852, it circulated privately for generations before reaching wider audiences. Often excerpted apart from the series, it is the most sustained and beautiful description of heavenly life in the Puritan tradition.
Coming soonModern
4 of 11 availableAbide in Christ
Andrew Murray
DevotionalThirty-one daily meditations on John 15 and the call to remain in Christ. Murray's devotional style is warm, simple, and deeply personal, making this an ideal companion for regular reading.
Around the Wicket Gate
Charles Spurgeon
SermonSpurgeon's plain-English invitation to faith, addressed directly to seekers and doubters. Each short chapter clears away a different obstacle to believing in Christ, with Spurgeon's characteristic warmth and directness.
Orthodoxy
G.K. Chesterton
TreatiseChesterton's account of how he arrived at orthodox Christian faith, written with wit, paradox, and unexpected joy. It is the most entertaining apologetics book ever written, and has brought more skeptics to serious engagement with Christianity than almost any other.
The Pursuit of God
A.W. Tozer
DevotionalA passionate call to move beyond formal religion into a living, firsthand experience of God. Tozer argues that the soul was made for God and will remain restless until it learns to pursue Him above all else.
A Serious Call to a Devout and Holy Life
William Law
TreatiseWilliam Law applies the demands of the gospel to every ordinary part of life, from how one prays to how one works and spends money, arguing that a divided life is no Christian life at all. It shaped the Evangelical Revival before it began: both John Wesley and George Whitefield credited it as decisive in their conversion and devotion. Written by a nonjuring clergyman outside the established church, it carries the unflinching moral logic of someone with no institutional career to protect.
Coming soonThe Everlasting Righteousness
Horatius Bonar
TreatiseHoratius Bonar traces the biblical logic of imputed righteousness from the Old Testament sacrificial system to its fulfillment in Christ, arguing that the believer's standing before God rests entirely on the completed work of Another. Written against moralistic dilutions of the gospel and the widespread uncertainties about assurance common in his day, it insists that justification is a once-for-all verdict, not a shifting condition. Bonar was the foremost hymn writer of the Scottish church in his generation, and his theological writing shares the same clarity and warmth his hymns display.
Coming soonHoliness
J.C. Ryle
TreatiseJ.C. Ryle examines sanctification not as an experience to be claimed but as a lifelong pursuit demanding the mortification of sin and active obedience to God. Written in part against the quietist tendencies of the rising Keswick movement, it defends a Reformed understanding of growth in grace grounded in Scripture and pastoral realism. Ryle was the most influential Anglican evangelical of his generation, and this remains his most widely read theological work.
Coming soonWith Christ in the School of Prayer
Andrew Murray
DevotionalAndrew Murray structures thirty-one lessons around the prayers and teachings of Jesus, taking the disciples' request to be taught to pray as the organizing question of the Christian life. Each lesson is short enough for daily reading but carries a sustained argument that prayer is not a discipline added to the Christian life but its animating center. Murray was one of the most prolific devotional writers of the nineteenth century, and this remains the most focused of his works on the nature and practice of prayer.
Coming soonAll of Grace
Charles Spurgeon
TreatiseCharles Spurgeon wrote this short book as a sustained offer of the gospel to the unconverted, taking its title from Romans 3:24 and its entire argument from the freeness of God's saving grace. It is among the most widely distributed of his works and was written late in his ministry as a distillation of everything he had preached at the Metropolitan Tabernacle. Clear in its theology and warm in its appeal, it moves from conviction of sin to assurance of faith in fewer than 120 pages.
Coming soonHumility
Andrew Murray
TreatiseAndrew Murray argues that humility is not one virtue among many but the root from which all other Christian graces grow, and that its absence explains most of what is wrong with both the church and the individual believer. Drawing from the life of Christ as the supreme model, each chapter examines a different dimension of what it means to take the lowest place. Short enough to read in a single sitting, it has been consistently commended as one of Murray's most penetrating and searching works.
Coming soonMy Utmost for His Highest
Oswald Chambers
DevotionalCompiled from lecture notes and talks by Oswald Chambers's wife after his death in 1917, this 366-entry devotional asks readers to abandon lesser ambitions and give themselves entirely to God. Each entry is short but cuts deep, shaped by Chambers's training in Wesleyan holiness theology and his years of YMCA ministry in Egypt. Few devotionals of the twentieth century have been as widely read or as persistently demanding.
