Christianity's Gift to the World

1. The Spread of Christianity: The Greatest Movement in History

Begin with a single scene: a locked upper room in Jerusalem, sometime around 33 AD. Inside, eleven frightened men — fishermen, a tax collector, a former political zealot — huddle in fear. Their leader has been publicly executed. Their movement appears finished. They are nobodies in a forgotten province of the Roman Empire.

Two thousand years later, that movement has 2.4 billion followers across every nation on earth. Christianity is the largest and most geographically widespread movement in the history of the human race — and it began without armies, without political power, without wealth, and without a single printed page.

The sheer historical improbability of this fact demands explanation.

The Early Church: Three Centuries of Persecution and Growth

Within 300 years of the Crucifixion, Christianity had gone from a persecuted Jewish sect in a small Roman province to the official religion of the Roman Empire. This is one of the most extraordinary social transformations in recorded history — and it happened entirely through persuasion, community, and witness, not conquest.

The Roman Empire — the most sophisticated military and administrative machine the ancient world had ever produced — tried systematically to destroy Christianity. The Emperor Nero (54–68 AD) blamed Christians for the Great Fire of Rome and subjected them to public torture and execution. The Emperor Domitian persecuted the Church at the end of the 1st century. The Emperor Diocletian launched the Great Persecution (303–313 AD), burning churches, confiscating Scriptures, and executing clergy throughout the empire.

They failed. Every single time. The faith not only survived — it accelerated. The early Church father Tertullian, writing around 200 AD, observed what every Roman official had noticed with bafflement:

"The blood of the martyrs is the seed of the Church." — Tertullian, Apologeticus, c. 197 AD

The Apostles: Witnesses Who Died for What They Had Seen

The testimony of the Apostles is among the most powerful historical data points in the Christian case. These were men who claimed to have personally witnessed the risen Jesus — seen him, touched him, eaten with him, spoken with him after his death. And then, one by one, they gave their lives for that claim.

Peter was crucified upside down in Rome. Andrew was crucified in Greece. James the Greater was beheaded. Thomas was speared to death in India. Bartholomew was flayed alive. Matthew was martyred in Ethiopia. Only John, the youngest Apostle, died of natural causes — though he endured exile and attempted execution by boiling in oil.

The historical principle here is simple and decisive: people die for what they believe is true. They do not die for what they know is a lie. The Apostles were not passing along a story they had heard secondhand. They were testifying to what they personally claimed to have witnessed. Their willingness to die rather than recant — when recanting would have saved their lives — is the most powerful kind of testimony a human being can give.

Medieval Missions: Bringing the Faith to the Nations

The spread of Christianity did not stop with the Roman Empire. Missionary activity across the centuries carried the faith to the ends of the known world — and with it came literacy, education, and human dignity.

St. Patrick (389–461 AD), himself a former slave, returned as a missionary to Ireland — the people who had enslaved him — and converted the entire island within a generation. Ireland would become a center of Christian scholarship that helped preserve learning through the darkest centuries of European history. St. Boniface (675–754 AD) evangelized the Germanic tribes of what is now Germany, establishing churches and monasteries that anchored medieval European civilization. St. Cyril and St. Methodius (9th century) brought the Gospel to the Slavic peoples — and in doing so, invented the Cyrillic alphabet so they could translate the Scriptures into the local language. Their priority was always the people, not conquest.

The Jesuit missions to Asia, Africa, and the Americas represent one of the greatest intellectual and cultural exchange programs in history. Jesuits like Matteo Ricci in China and Roberto de Nobili in India learned local languages, studied local cultures, translated Scripture, built schools, and engaged indigenous scholars in genuine dialogue. They did not bring a sword. They brought a book, a school, and a hospital.

Christianity Today: Not Dying — Shifting

The popular narrative in secular Western media is that Christianity is dying. The data tells a different story. Christianity is not declining globally — it is relocating. The faith is growing at extraordinary rates in sub-Saharan Africa, where it has expanded from 10 million Christians in 1900 to over 685 million today. In China, despite official state atheism, there are an estimated 100 million Christians — a number that has grown entirely through underground churches and personal witness. South Korea, with no significant Christian presence before the 19th century, is now roughly 30% Christian and sends more missionaries per capita than any other nation.

What died in the upper room in Jerusalem two thousand years ago did not stay dead — and neither did the movement it spawned.

Rodney Stark

Sociologist, Distinguished Professor of Social Sciences, Baylor University

Author of The Rise of Christianity: How the Obscure, Marginal Jesus Movement Became the Dominant Religious Force in the Western World in a Few Centuries (HarperOne). Stark used rigorous sociological modeling to analyze the early Church's growth rates and concluded that Christianity's extraordinary spread was driven by its unique message of love, radical equality, and practical care for the sick and poor — not by political power or coercion. His work transformed academic understanding of early Christian history and remains a landmark in the sociology of religion.

2. The Christian Moral Code: A Revolution in Human Values

Volunteers helping those in need — a practice rooted in the Christian command to love one's neighbor — The Christian obligation to serve the poor and vulnerable transformed the ancient world — and it continues to transform ours.

Before Christianity arrived, the ancient world operated on a set of moral assumptions that most modern people would find grotesque. The Roman Empire — which prided itself on civilization, law, and philosophy — practiced widespread infanticide. Unwanted newborns, especially girls and the disabled, were routinely left exposed to the elements to die. This was legal. It was normal. It was unremarkable.

Slavery was universal across every ancient civilization, without exception. The sick and the poor were, in most cases, left to fend for themselves — their suffering was simply the natural order of things. The powerful were admired; the weak were despised. The philosopher Aristotle explicitly argued that some people were "slaves by nature." Even Plato's ideal Republic rested on rigid class hierarchy and the philosophical dismissal of ordinary people.

Christianity detonated this entire worldview.

Ideas That Changed the World

The Christian revolution in moral thought was not a gradual evolution — it was a series of radical claims, unprecedented in the ancient world, that have since become so embedded in Western culture that we mistake them for common sense.

Imago Dei — the image of God. Every human being, regardless of race, sex, social class, age, or disability, possesses inherent and inviolable dignity — because every human being is made in the image of God (Genesis 1:27). This single idea is the foundation of every human rights framework that has ever existed. It is not a Greek idea. It is not a Roman idea. It is a Jewish and Christian idea.

Love your enemy. Jesus taught: "Love your enemies, do good to those who hate you, bless those who curse you, pray for those who mistreat you" (Luke 6:27–28). No other ethical system in the ancient world — not Stoicism, not Buddhism, not Confucianism, not Platonism — taught anything remotely like this. This was not a philosophical abstraction. It was a command to be enacted in daily life.

Care for the poor as a moral obligation. "Whatever you did for the least of these brothers and sisters of mine, you did for me" (Matthew 25:40). In the ancient world, charity to the poor was admired as a social grace — a way to demonstrate wealth and earn honor. Christianity transformed it into a sacred duty. The poor were not unfortunate obstacles; they were Christ in disguise.

Universal equality before God. Writing in the 1st century AD — centuries before any political movement for equality — St. Paul declared: "There is neither Jew nor Greek, slave nor free, male nor female, for you are all one in Christ Jesus" (Galatians 3:28). This was not a statement about political organization; it was a statement about the nature of reality. And it planted a seed that, over centuries, would bear fruit in the abolition of slavery, women's suffrage, and the universal declaration of human rights.

Nietzsche Understood What Secularism Forgets

The philosopher Friedrich Nietzsche — a committed atheist and one of the most penetrating critics of Christianity in intellectual history — despised Christianity precisely because he understood its moral revolution so clearly. Nietzsche argued that Christianity had overthrown the natural "master morality" of the ancient world — the admiration of strength, beauty, and power — and replaced it with a "slave morality" that exalted humility, compassion, and care for the weak.

He called this a catastrophe. But he was absolutely correct that Christianity had inverted the ancient value system. What he could not bring himself to admit was that the inversion was a moral improvement — that a civilization built on compassion is more worthy of the name than one built on power.

Tom Holland

Secular Historian, Author of Dominion: How the Christian Revolution Remade the World

Tom Holland is a prominent British historian and self-described non-Christian who spent years researching the roots of Western values for his book Dominion. He entered the project expecting to confirm the standard secular narrative — that Western liberalism descended from ancient Greece and Rome. What he found, after years of research, forced him to reverse his position entirely. He concluded that virtually all modern Western values — human rights, equality before the law, compassion for the weak, the prohibition of torture, the concept of universal dignity — are derived entirely from Christianity. They are not Enlightenment inventions; the Enlightenment itself was built on a Christian moral foundation it had inherited without acknowledging.

"The West remains utterly saturated by Christian assumptions... the very notion of human rights is a Christian one. The very notion of equality before the law is a Christian one. I realized that I couldn't understand the modern world without understanding Christianity." — Tom Holland, secular historian, author of Dominion

3. Hospitals: Christianity Invented Them

A modern hospital corridor — an institution whose very concept was invented by Christians — The hospital — one of humanity's most vital institutions — was invented by the Catholic Church in the 4th century.

In the ancient world, if you were sick and poor, you died alone. There was no institution for the care of the sick poor. Greek medicine was real and sophisticated — but it was available only to those who could pay. Roman society had no public health infrastructure for the destitute. When plague struck a Roman city, the standard civic response was to expel the sick or simply leave them.

Christians behaved differently — and the difference was noticed. During the Antonine Plague (165–180 AD) and the Plague of Cyprian (249–262 AD), which together may have killed one-third of the Roman Empire's population, pagan Romans fled the cities. Christians stayed and nursed the sick — their own and their neighbors' — at great personal risk. The pagan Emperor Julian (who tried to reverse Christianity's spread) complained bitterly that Christians were winning converts precisely because of their practical compassion: "the impious Galileans support not only their own poor but ours as well."

St. Basil and the World's First Hospital

The first institution in the Western world that we would recognize as a hospital — with separate wards for different diseases, trained medical staff, free care for the poor, and a system of organized nursing — was built by a Christian bishop.

Around 370 AD, St. Basil of Caesarea founded what contemporaries called the Basileias — a vast complex outside the city of Caesarea in Cappadocia (modern Turkey). It included a hospice for travelers, a poorhouse, housing for workers, separate facilities for those with infectious diseases, and a section specifically for the treatment of lepers, who were otherwise universally shunned. Basil himself reportedly worked in the leper ward. It was staffed by physicians, nurses, and porters — an organized medical institution, not merely an act of private charity.

The historian Gary Ferngren, in his study Medicine and Health Care in Early Christianity, identifies the Basileias as the world's first hospital in the full modern sense of the word. Its model spread throughout the Christian world within decades.

The Knights Hospitaller and the Americas

The Knights of St. John — known as the Knights Hospitaller — were founded in Jerusalem around 1099 with a specific mission: to care for sick pilgrims. Their hospital in Jerusalem was one of the wonders of the medieval world, capable of treating up to 2,000 patients simultaneously, with dedicated beds, regular meals, and trained physicians. The Knights' commitment to care extended across enemy lines — they treated Muslim patients alongside Christian ones.

When Catholic missionaries and conquistadors reached the Americas, hospitals followed immediately. The Hospital de Jesús Nazareno in Mexico City, founded in 1524 by Hernán Cortés and Bishop Fray Juan de Zumárraga, is one of the oldest continuously operating hospitals in the Western Hemisphere — and it is still open today, still treating patients, nearly five centuries after its founding.

Today, the Catholic Church operates the largest non-governmental health care network on earth.

4. Universities: Christianity Invented Those Too

Rows of books in a great library — a tradition born from the Christian conviction that the universe is rational and knowable — The university — the Western world's greatest intellectual institution — was conceived and built by the Catholic Church.

The ancient world had schools, academies, and libraries. But the university — an institution with a formal curriculum, a system of degrees, the freedom to debate and challenge received wisdom, and a self-governing community of scholars — was a medieval Catholic invention.

Every major medieval European university was founded under the direct authority or sponsorship of the Catholic Church:

University of Bologna (1088) — the oldest university in continuous operation in the Western world
University of Oxford (~1096) — grew from the cathedral school tradition
University of Paris (~1150) — founded under the authority of the Bishop of Paris; home of Thomas Aquinas
University of Cambridge (1209) — chartered by the Pope
University of Salamanca (1218) — granted its royal charter by Pope Alexander IV

By 1500, there were over 80 universities in Europe — all of them founded under Catholic auspices. The lecture system, the doctoral degree, the concept of academic freedom, the disputatio (formal structured debate as a method of truth-seeking) — these are all Catholic inventions, inherited by every university in the world today.

The Jesuits and the Modern World

The Society of Jesus — the Jesuit order, founded by St. Ignatius of Loyola in 1540 — went on to build the most extensive private educational network in human history. The Jesuits have founded 189 universities worldwide, including Georgetown University, Fordham University, Boston College, Loyola University, Marquette University, and dozens of institutions across Asia, Africa, and Latin America. Their mission was explicit: education for all, regardless of social class, was an act of service to God and to humanity.

Why? Because the Universe Is Rational

The Christian investment in education and scholarship is not accidental. It flows directly from a theological premise: the universe was created by a rational God, and therefore the universe is rational — ordered, lawful, and knowable. To study the natural world is to read the mind of God. To seek truth is an act of worship.

This premise is precisely what made modern science possible — and it is distinctly Christian. As Alfred North Whitehead argued, modern science arose in Christian Europe and nowhere else because only Christian Europe believed in a universe governed by consistent rational laws established by a personal Creator.

Sciences Founded or Advanced by Catholic Clergy

The same Church that built the universities produced many of the scientists who built modernity:

Gregor Mendel (Augustinian friar) — founded the science of genetics through his meticulous pea-plant experiments in the monastery garden at Brno
Fr. Georges Lemaître (Catholic priest and physicist) — proposed the Big Bang theory of the origin of the universe, which atheist scientists initially resisted
Roger Bacon (Franciscan friar) — pioneered the empirical scientific method in the 13th century, insisting that claims about nature must be tested by observation
Nicolaus Copernicus (canon of the Catholic Church) — proposed the heliocentric model of the solar system
Albertus Magnus (Dominican friar, Bishop) — one of the greatest natural scientists of the Middle Ages, teacher of Thomas Aquinas, patron saint of natural scientists

The cliché that the Church was "anti-science" collapses entirely on contact with history.

5. Orphanages, Social Care, and the Abolition of Slavery

The First Orphanages

In the ancient Roman world, orphaned and abandoned children had no institutional protection. Infanticide and child abandonment were commonplace. Christianity changed this immediately. The Council of Nicaea (325 AD), the first ecumenical council of the Church, directed every cathedral city to establish a hospice — a xenodochium — that would care for the sick, the poor, pilgrims, and orphaned children. This was the first time in history that organized child welfare had been mandated on a civilizational scale.

St. Jerome (4th century) and the noblewoman St. Fabiola (who converted after a scandalous personal history and gave her fortune to the poor) established dedicated orphanages and hospitals in Rome. The model spread throughout the Christian world. By the medieval period, every major city in Christian Europe had Church-run orphanages, hospitals, and homes for the poor — funded by the tithes of ordinary believers and managed by religious orders.

The Abolition of Slavery

No institution in Western history has been more falsely accused of supporting slavery than the Catholic Church — and no institution did more, over a longer period of time, to undermine it.

From the earliest centuries, Christian thinkers insisted on the full humanity and spiritual equality of slaves. Popes from Gregory I onward released slaves as acts of piety. Pope Gregory XVI's apostolic constitution In Supremo Apostolatus (1837) explicitly condemned the slave trade — not merely in theory, but in direct condemnation of the Atlantic slave trade then still operating.

In Britain, the man who did more than any other to end the slave trade was William Wilberforce — a deeply devout Evangelical Christian who spent 26 years of his parliamentary career fighting for abolition specifically because of his Christian conviction that every human being bore the image of God. When the Slavery Abolition Act passed in 1833, Wilberforce was on his deathbed. He died three days later. His last great work was done.

In the United States, the abolition movement was driven overwhelmingly by Christians — Quakers, Methodists, and evangelical Protestants — who grounded their opposition to slavery in Scripture and in the Christian doctrine of human dignity. The Quakers were the first religious body in American history to formally condemn and prohibit slaveholding among their members, in 1688.

Prison Reform and Care for the Incarcerated

Elizabeth Fry (1780–1845), a Quaker Christian and the woman whose face appeared on the British five-pound note for many years, pioneered prison reform in Britain at a time when prisons were filthy, overcrowded warehouses of human misery. She visited Newgate Prison in 1813, was horrified by what she found, and spent the rest of her life fighting for humane conditions, education for prisoners, and rehabilitation rather than mere punishment — all motivated explicitly by her Christian faith.

In the modern era, the Prison Fellowship — founded by Charles Colson, President Nixon's former aide who converted to Christianity while facing prison himself — operates in over 120 countries, bringing volunteer mentorship, rehabilitation programs, and human dignity to prisoners worldwide.

Education for the Poor

Before Christianity, formal education was the exclusive preserve of the wealthy. In medieval Europe, the Church changed this: monastic schools educated anyone who showed promise, regardless of birth. Parish schools provided basic literacy across Europe. The Jesuit Ratio Studiorum — a comprehensive educational curriculum developed in 1599 — made rigorous classical education available to the poor across Europe and the Americas, centuries before the concept of public education existed.

6. Art, Music, and the Culture of the West

A great Gothic cathedral — the most ambitious architectural achievement of the medieval world, built entirely for the glory of God — The Gothic cathedral — Notre Dame, Chartres, Cologne, Salisbury — stands as the most ambitious architectural achievement in human history. Built by ordinary believers for the glory of God.

It is impossible to understand Western civilization without understanding Christianity — because Christianity built Western civilization, in the most literal sense. Its finest art, its greatest music, its towering architecture, and its most enduring literature all emerged directly from the Christian faith.

The Visual Arts

Michelangelo's Sistine Chapel ceiling (1508–1512) is the most celebrated single artwork in human history — and it is an act of theological proclamation. The Creation of Adam, the Prophets, the Sibyls, the Last Judgment — the entire program is a meditation on salvation history. Michelangelo, who spent four years on his back painting this ceiling, considered it an act of prayer as much as an act of art.

Raphael's frescoes in the Vatican's Stanza della Segnatura — including the School of Athens and the Disputa del Sacramento — place ancient reason and Christian revelation in dialogue as complementary paths to truth. Leonardo da Vinci's The Last Supper (1495–1498) remains one of the most analyzed and reproduced paintings ever made. Jan van Eyck, Rembrandt, El Greco, Caravaggio — the entire tradition of Western painting is inseparable from Christian patronage, Christian subject matter, and Christian theology.

Music

The greatest music in human history was composed in explicit service of the Christian faith.

Johann Sebastian Bach signed his manuscripts with the letters S.D.G. — Soli Deo Gloria ("To God alone the glory"). His Mass in B Minor is widely considered the greatest musical composition ever written. George Frideric Handel composed the Messiah (1741) — including the Hallelujah chorus — as a work of Christian devotion; he reportedly wept while writing it and said he felt he saw "the great God himself" before him. Mozart's Requiem, left unfinished at his death, is one of the most profound sacred works in the Western canon. Beethoven's Missa Solemnis (1823), which Beethoven himself considered his greatest work, was composed, as he wrote, "from the heart — may it speak to the heart."

Gregorian chant, the polyphony of Palestrina, the cantatas of Bach, the oratorios of Handel, the sacred works of Vivaldi, Verdi, Brahms, and Bruckner — Western music is, at its core, a 1,500-year act of praise.

Architecture: The Cathedral

The Gothic cathedral is the most ambitious thing human beings have ever built. Notre Dame de Paris (construction began 1163), Chartres Cathedral (begun 1194), Cologne Cathedral (begun 1248, completed 1880), Salisbury Cathedral (begun 1220) — these structures required generations of labor, breathtaking engineering innovation, and the organized sacrifice of entire communities. They were built not for kings or emperors, but for God — and for ordinary worshippers who would enter and be lifted, physically and spiritually, toward heaven.

The Gothic cathedral introduced pointed arches, ribbed vaults, and flying buttresses — engineering solutions that allowed walls to dissolve into vast windows of colored light. This was theology in stone and glass: an entire building designed to make the human being feel small before transcendence, then fill that smallness with light.

Literature

The greatest works of Western literature are Christian in their bones. Dante Alighieri's Divine Comedy (1308–1320) is the foundation text of the Italian literary tradition and one of the supreme achievements of the human imagination — a systematic poetic exploration of sin, purgation, and divine love. John Milton's Paradise Lost (1667) is the greatest epic poem in the English language, a theological meditation on the Fall and the possibility of redemption.

Fyodor Dostoevsky's The Brothers Karamazov (1880) is arguably the greatest novel ever written — and it is a sustained engagement with the problem of evil, the existence of God, and the redemptive power of love. J.R.R. Tolkien, a devout Catholic, described The Lord of the Rings as "a fundamentally religious and Catholic work" — its themes of sacrifice, eucatastrophe (the sudden joyous turn), and the hope that transcends apparent defeat are explicitly drawn from Christian theology. C.S. Lewis, who converted from atheism to Christianity after long conversations with Tolkien and others, produced in Mere Christianity, The Problem of Pain, The Screwtape Letters, and the Narnia series some of the most widely read Christian apologetics and literature of the 20th century.

Painting

Sistine Chapel, The Last Supper, Raphael's Vatican frescoes, Rembrandt's biblical scenes — the entire tradition of Western visual art is rooted in Christian faith and patronage.

Music

Bach's Mass in B Minor, Handel's Messiah, Mozart's Requiem, Beethoven's Missa Solemnis — the greatest music in human history was composed as acts of Christian worship.

Architecture

The Gothic cathedral — Notre Dame, Chartres, Cologne — remains the most technically daring and spiritually ambitious building program in human history.

Literature

Dante's Divine Comedy, Milton's Paradise Lost, Dostoevsky's Brothers Karamazov, Tolkien's Lord of the Rings — Christianity is the animating soul of Western literature.

"The West remains utterly saturated by Christian assumptions... the very notion of human rights is a Christian one. The very notion of equality before the law is a Christian one. I realized that I couldn't understand the modern world without understanding Christianity. Remove Christianity from Western civilization and you would not recognize what remained." — Tom Holland, secular historian, author of Dominion: How the Christian Revolution Remade the World

The Evidence Speaks for Itself

The critics of Christianity like to speak of what the Church has done wrong — the Inquisition, the Crusades, the failures of individual Christians and corrupt institutions. These are real. No serious Christian apologist pretends otherwise. Human institutions composed of fallen human beings will always carry the stain of human sin.

But the accounting must be complete. When you strip away selective history and look at the full record, the Christian faith emerges as the single greatest force for human flourishing in the history of civilization. It invented the hospital, the university, and the orphanage. It planted the seeds of science, abolished slavery, reformed prisons, educated the poor, and established the moral foundations on which every modern human rights framework rests. It gave the world its greatest art, its greatest music, its greatest architecture, and its greatest literature.

And it did this not because Christians were better people than anyone else — but because they were following a Teacher who told them that every human being was made in the image of God, that the last shall be first, that whatever they did to the least of their brothers and sisters they did to him.

A faith that produced that record does not merely deserve a fair hearing. It deserves to be taken seriously as the most transformative force in human history.
