The Imitation of Christ is a short devotional book written around 1420 by a Dutch monk, Thomas à Kempis, for the young men in his monastery. It is often called the most widely read Christian book after the Bible, and whether or not that is strictly true, it has been in continuous use for six centuries by Catholics, Protestants, and people who barely know what they believe. Its subject is simple: how to follow Jesus from the inside — with a humble mind, a quiet heart, and a love that prefers him to everything.
This guide explains what the book is, what its four parts teach, the lines everyone quotes, the things a modern reader should weigh, and how to read it in a way that actually changes something. The full text is free in the Ochorus library.
Who wrote it, and why
Thomas Hemerken was born around 1380 in Kempen, a small town near Cologne, which is why he is known as Thomas à Kempis, Thomas of Kempen. As a boy he was sent to a school in Deventer run by the Brethren of the Common Life, a movement of ordinary believers who lived simply, copied books, and pursued what they called the devotio moderna, the modern devotion — a Christianity of the heart rather than of the schools. Thomas entered the monastery of Mount St Agnes near Zwolle, was ordained, and stayed there for the rest of a long life, copying manuscripts (he copied the whole Bible by hand more than once), training novices, and writing. He died in 1471.
The Imitation was written for those novices. It circulated at first without an author’s name, which is fitting for a book whose first chapters warn against wanting to be known. It was copied and translated all over Europe within decades, and has never gone out of print since printing existed.
It is worth knowing that it was not written as a system. It is four short books of brief chapters, each chapter a page or two, each meant to be read slowly and then lived with. It is closer to a collection of counsels from an older brother than to a treatise. That is its strength and its whole method.
The four books
Book One: Counsels on the spiritual life. This is the part most people know. It opens with John 8:12 — “He who follows me walks not in darkness” — and then goes straight for the reader’s pride. The first chapter contains the line that sets the tone for everything:
What good does it do to speak learnedly about the Trinity if, lacking humility, you displease the Trinity?
Thomas à Kempis, The Imitation of Christ
Book One is about the ordering of a life: humility, silence, avoiding idle talk and rash judgement, bearing with other people’s faults, the value of adversity, resisting temptation, and the seriousness of death and judgement. It is practical to the point of bluntness. It assumes that the great obstacle to knowing God is not ignorance but self-importance, and it goes after that obstacle in every chapter.
Book Two: Counsels on the inner life. Shorter, and warmer. Here Thomas turns from behaviour to the heart: the kingdom of God is within you, so learn to withdraw into it. He writes about a good conscience, about loving Jesus above all things and having him as a friend, and about the cost of that friendship. The last two chapters, on the few who love the cross and on the royal road of the holy cross, are the summit of the book:
In the cross is salvation, in the cross is life, in the cross is protection from enemies, in the cross is infusion of heavenly sweetness.
Thomas à Kempis, The Imitation of Christ
This is Galatians 6:14 and Matthew 16:24 made into a way of life. Thomas does not soften the cross; he says that the whole life of Christ was a cross and a martyrdom, and that anyone who wants to follow him will find that the road is the same. But he also insists that it is the cross, and not comfort, that carries the sweetness with it.
Book Three: On inward consolation. The longest part, and different in form: it is a conversation. Christ speaks, and the disciple answers, back and forth, chapter after chapter. Here the book becomes prayer. The disciple confesses weakness, distraction, and fear; Christ answers with patience, correction, and promise. Many readers find this the part they return to most, because it gives them words — the words of a soul that wants God and knows it is not yet what it should be. It contains the observation that has stung readers for six hundred years:
For a small gain they travel far; for eternal life many will scarcely lift a foot from the ground.
Thomas à Kempis, The Imitation of Christ
Book Four: On the Blessed Sacrament. A set of meditations for receiving communion, in the same dialogue form. It is the most specifically Catholic part of the book, and the part Protestant readers have most often set aside. But even here the theme is the same as everywhere else: come to Christ humbly, hungrily, and often.
What the book teaches
If you had to reduce the Imitation to a few sentences, they would be these.
Humility comes before knowledge. Thomas was not against learning; he spent his life copying books. But he saw that knowledge without humility makes a person worse, not better, which is exactly what 1 Corinthians 8:1 says: knowledge puffs up, but love builds up. His most-quoted sentence after the one on the Trinity is “I would rather feel contrition than know how to define it.” That is the whole book in a line. A broken and contrite heart, Psalm 51:17, is worth more than a correct one.
The world cannot satisfy you, so stop asking it to. Thomas quotes Ecclesiastes 1:2 early and often: vanity of vanities. He is not sour about creation; he is realistic about the heart. Everything you grasp at slips, and everything you hold loosely stays sweet. This is 1 John 2:15–17 lived out: the world passes away, and its desire, but the one who does the will of God abides for ever.
Christ is to be loved for himself, not for his gifts. Book Two’s chapters on the friendship of Jesus draw a hard line between those who love him for consolations and those who love him in the dark. The test of love is what happens when the comfort is withdrawn. Job 13:15 is behind this: though he slay me, yet will I trust him.
The way is the cross. Not as a doctrine to believe but as a shape for a life: self-denial, patience under wrong, the acceptance of what God sends. Luke 9:23 is the verse Thomas returns to: take up the cross daily. Daily is the word.
Peace comes from inside. A person at peace with God can be at peace anywhere; a person at war with himself will find fault with paradise. Thomas keeps sending the reader inward, not to find themselves, but to find Christ, who according to Luke 17:21 has made his kingdom there.
Who has read it
The list is one of the reasons to read it. Thomas More read it; so did Ignatius Loyola, who kept it by him all his life. John Wesley read it as a young man at Oxford, and it was one of the books that turned him toward a serious pursuit of holiness; he later published his own English abridgement, The Christian’s Pattern, so that Methodists could carry it. John Newton read it. General Gordon carried it to Khartoum. George Eliot gave it to Maggie Tulliver in The Mill on the Floss as the book that changed her. Dietrich Bonhoeffer had it with him in prison. It has been the private companion of people who agreed about almost nothing else, which suggests that it touches something underneath their disagreements.
What to weigh as you read
An honest guide should say what the book is not.
It was written by a monk, for monks, and it shows. Its ideal is solitude, silence, and withdrawal; it has little to say about marriage, work, children, or the public good. Read it as a corrective and it is medicine; read it as a complete map of the Christian life and it will leave whole rooms of the house dark. Thomas himself would have said that the book is for the interior, and that the exterior is another matter.
Its tone about the world is often severe. Some of that is the fifteenth century, and some of it is a genuine tilt toward contempt for created things that Scripture does not share. Genesis 1:31 says that God saw everything he had made, and it was very good. Hold the Imitation against that verse and take what stands.
It is light on the gospel as announcement. Thomas assumes justification and writes about sanctification; he is a book for people already inside. If you are not sure you are inside, read Spurgeon’s All of Grace first, and then come back. The Imitation will mean far more once you know that the love it describes has already been given to you, as Romans 5:5 says, by the Holy Spirit.
And it is not a Protestant book, though Protestants have loved it. Book Four in particular assumes a theology of the Mass that most evangelical readers will not share. Wesley’s solution was to abridge. Yours can be to read Books One to Three with a whole heart and to read Book Four as the prayers of a brother in another room.
How to read it
A chapter a day. The chapters are short on purpose. One a day, morning or night, with a few minutes of silence after, is the pace the book was written for. Reading it straight through like a novel is the one way to make it not work.
Read it as prayer. Especially in Book Three, do not analyse; answer. When the disciple speaks, speak with him. When Christ speaks, let it be spoken to you.
Keep a pencil. Underline the sentence that stings. There will be one on almost every page, and it will be the one meant for you.
Read with your Bible open. Thomas quotes or echoes Scripture constantly, usually without a reference. When a line sounds like the Psalms, it probably is the Psalms. Finding the source doubles the meaning.
Give it a year, not a week. People who have loved this book have usually read it dozens of times over decades, a little at a time. It is not a book you finish; it is a book you keep.
Micah 6:8 asks what the Lord requires: to do justly, to love mercy, and to walk humbly with your God. The Imitation is a six-hundred-year-old training manual for that last clause. It will not make you learned. It may, if you let it, make you humble, and that, Thomas would say, is the only thing that was ever going to please the Trinity.
