Cluny Reform Movement: What 2 Kings 23 Teaches Renewal
Short answer: The Cluny reform movement was a renewal effort that began in 910 at the Burgundian monastery of Cluny and spread across western Europe over the following two centuries. Its aim was a church and a monasticism less entangled with feudal power, money, and local lords. Its instincts are not new. In 2 Kings 23:1-25, King Josiah responds to the rediscovered Book of the Law by gathering the people, reading the covenant aloud, purging idols, and restoring the Passover. Josiah's reform worked from the inside out: the Word was heard, the king humbled himself, the covenant was renewed, and only then were the high places torn down. Cluny worked the same way in its own sphere, not by conquering the world but by reforming a house at a time.
What the Cluny reform movement actually was
Cluny began as a single monastery founded in 910 in Burgundy, under the protection of the pope rather than a local nobleman. That detail mattered more than it sounds. When a monastery answered to a local lord, its abbot could be a layman, its lands could be seized, and its prayers could be traded like rents. Cluny's founders deliberately cut those strings, placing the house under the apostle Peter's oversight so that no bishop or baron could easily claim it.
From that independence grew a network of daughter houses that shared one abbot and one pattern of life. Monks gave themselves to the Psalms, to manual labor, and to a plain, unhurried worship that struck contemporaries as unusually sober. Prayer became Cluny's offering to a violent society, and the movement's influence spread through reputation rather than conquest.
It is worth saying plainly what Cluny was not. It was not a theological revolution, not a break with the church's institutions, and not an attempt to form a new church. It was a disciplined attempt to live the existing faith seriously, beginning with the daily life of a single community.
The problem Cluny answered, and the problem Josiah answered
The tenth-century church faced two persistent troubles. One was simony, the buying and selling of church offices. The other was clerical marriage and the family interests that came with it, which tied church property to dynasties. Behind both stood the same reality: the church had been folded into the feudal order until its offices looked like property and its ministers like vassals.
Judah's problem in 2 Kings 23 had the same shape. The temple was still standing and the ritual was still running, but the house of Yahweh had been filled with vessels made for Baal, and the horses and chariots of the sun stood at its entrance. Paganism was not outside the gates; it had been moved inside the sanctuary.
Josiah's reform did not begin with that furniture. It began when Hilkiah the high priest said, as 2 Kings 22:8 records, that he had found the book of the law in Yahweh's house. The Word of God was present in the building and unread, which is the most dangerous condition a religious institution can be in.
Why reading the book came before tearing down the shrines
The order of Josiah's actions is not incidental. He did not first shut the high places and then consult a scroll. The reading came first, then the king tore his clothes. The tearing of garments is the outward sign of a heart that has suddenly seen the distance between what God commanded and what his people had tolerated for generations.
Only after that does 2 Kings 23:1-25 describe the king sending, gathering the elders, and reading the covenant in their hearing. The sequence is consistent with 2 Chronicles 34 and with Nehemiah 8, where Ezra reads the law before the people rather than assuming they know it. Renewal in Scripture is not primarily a matter of new programs.
The practical lesson is uncomfortable but clear. Reform that begins with the removal of abuses will eventually run out of abuses to remove. Reform that begins with the hearing of Scripture keeps supplying its own agenda, because the Word continues to expose what the reformers did not yet see.
Josiah's reform: covenant, purge, and Passover
After the reading, Josiah stood by the pillar and made a covenant before Yahweh, and the text tells us the people joined him. Then came the purge. The vessels for Baal were brought out of the temple and burned. The idolatrous priests were deposed. The Asherah was cut down. The houses of the male shrine prostitutes were broken down.
The purge extended past Jerusalem to the high places throughout Judah and even into the territory of the former northern kingdom. Josiah also removed the horses that kings of Judah had dedicated to the sun, and he defiled the high places Solomon had built. Verse 25 gives the verdict that no king before or after him turned to Yahweh with such a whole heart.
Then came the Passover, and the text says no such Passover had been kept since the days of the judges. What is striking is that the reform climaxed in worship, not in demolition. The point of removing the false was to restore the true, which is exactly the shape the Cluny movement gave its own work.
How Cluny's reforms worked in practice
Cluny's reforms were concrete rather than sentimental. Abbots were chosen from within the community. Lay control of monastic property was rejected. The liturgy was performed with care and length, and monks were expected to be present for it. Manual work and hospitality to the poor were built into the day rather than left to impulse.
Because the monastery reported to the pope, its property could not simply be inherited by a noble family. That single structural decision freed Cluny to pursue its religious aims without constantly defending its land from the sons of its patrons. Later popes and councils took up similar concerns about simony and clerical marriage on a wider scale.
Whether Cluny's wealth in later centuries undercut its original simplicity is a fair question, and historians do not agree on how to weigh it. What is not disputed is that the movement began with the reform of a single household's daily obedience, not with a demand that the whole world change first.
From Hilkiah to Cluny to every generation: renewal is repetitious
One of the most sobering features of 2 Kings 23 is what follows it. Josiah's reform was real and its verdict is glowing. Yet the same book that praises Josiah also records that the judgment on Judah was not turned away, and within a generation the temple was burned. Josiah's own sons reversed much of what he did.
That pattern repeats through Scripture. Hezekiah's reforms are followed by Manasseh's apostasy. Ezra's revival is followed by Nehemiah's painful discovery that the covenant had been broken again. The risen Christ himself says to a faithful church in Revelation 2:4-5, that he has this against them, that they left their first love.
This is why renewal movements must be understood as recurring rather than final. Cluny did not end the church's problems, and no Christian reform ever has. Each generation receives the Word again, hears it as if for the first time, and does the unglamorous work of ordering its common life around what it has heard.
What a modern reader should and should not take from Josiah
Josiah's reform is a genuine model of how a community returns to God: Scripture read publicly, leaders humbled, covenant renewed, idols dismantled, worship restored. Those elements are not tied to ancient Israel's national politics and can be embraced by any congregation honestly.
What should not be imported is the machinery of a theocratic state. Josiah could command the destruction of shrines because he was a king over a nation with a covenant. Christians today are not commissioned to use civil force against other people's worship, and the New Testament nowhere authorizes it. The church's weapon is the Word and the witness of a reformed life.
So the honest transfer is this: let the book be read aloud and actually obeyed, let leaders be the first to humble themselves, and let the community put away what it has quietly tolerated. That is Josiah's method, and it is Cluny's method, and it does not require a throne.
Biblical fidelity check
2 Kings 23:1-25 establishes that Josiah gathered the elders, read the covenant, renewed it, purged idolatrous objects and personnel from the temple and the land, and restored the Passover. It establishes a genuine, divinely commended reform, and it presents the public reading of Scripture as the trigger for it. The passage does not promise that such reform will avert every consequence of prior sin, and it does not make political power the necessary instrument of renewal.
A common misreading treats Josiah's purge as a warrant for religious coercion, as though faithful Christians should seek state power to suppress other worship. That is wrong because the passage is about a covenant king in a covenant nation, a category that no modern believer occupies, and because the New Testament consistently advances the faith by proclamation and suffering rather than by the sword. Another misreading treats Josiah's reform as final, guaranteeing lasting revival. The following chapters show it was not; the reform was real and the decline after it was also real.
Other passages that speak to 2 Kings 23:1-25
Renewal under the Word runs through the whole canon. In 2 Kings 22:8-13, Hilkiah the high priest said, “I have found the book of the law in Yahweh’s house.” In 2 Chronicles 29:3-11, Hezekiah opened the doors of Yahweh’s house and repaired them, another reform led by a king. In Nehemiah 8:1-12, the people gathered as one man and asked Ezra to bring the book of the law of Moses, and the reading produced both weeping and joy. In Matthew 15:1-9, Jesus warns that worship can be taught by the commandments of men while the heart is far from God. These themes connect directly with 1 Chronicles 1: Adam to Edom's Chiefs, 1 Chronicles 10: Saul's Death and the Kingdom Given to David, 1 Chronicles 11: David Anointed King and His Mighty Men, and 1 Chronicles 12: David's Mighty Men and the United Kingdom.
Frequently asked questions
What was the Cluny reform movement?
It was a renewal that started in 910 at the monastery of Cluny in Burgundy and spread through a network of dependent houses over roughly two centuries. Cluny placed itself under papal protection rather than a local lord, chose its own abbots, rejected lay control of its property, and pursued a disciplined life of prayer, work, and hospitality. Its wider influence touched later efforts to address simony and clerical marriage. It was a reform of existing church life, not a new church.
How does Josiah's reform in 2 Kings 23 compare with movements like Cluny?
The parallels are structural rather than historical. Both begin with Scripture being heard and taken seriously. In 2 Kings 23:1-25, the king gathers the people and reads the covenant before any purge begins. Both reforms operate from the inside out, addressing the daily life and worship of a particular community before attempting anything broader. Both are also followed by later decline, which is why Scripture presents renewal as something each generation must take up again rather than inherit automatically.
Does 2 Kings 23 support using political power for religious reform?
No, not directly. Josiah was a covenant king over a covenant nation, and his authority to purge the land belonged to that specific office and setting. Nothing in the passage commands Christians to seek civil power to suppress the worship of others, and the New Testament consistently advances the faith through proclamation, suffering, and holy living instead. Faithful Christians differ on how much influence believers should seek in public life, but Josiah's purge is not a charter for coercion.
