The Separation of Church and State in France. 

When I think of the French Revolution, I envision a political earthquake. If we set aside the images of brutal violence and gore for a moment, the Revolution was a full-on reimagining of society, identity, and power. We might remember it for the beheadings, the storming of the Bastille and the fall of the monarchy, but some of the most significant changes came from something quieter but just as radical.

The attempt to pull religion out of politics altogether.

For centuries, the Catholic Church and the French monarchy were inextricably linked. The Church went beyond being a mere spiritual institution and was embedded in law, political power, land ownership, and almost everything in everyday life.

So, when the revolutionaries set out to build a new society, the separation of the Church from the state was more than an administrative decision. It was another revolution within the Revolution.

Why did the Church and state part ways, and why is it still relevant in France today? It helps to understand the pre-revolution background in more detail.

Before 1789, the Catholic Church was everywhere in French life. You couldn’t escape it, permeating almost all aspects of life. At the time of the Revolution, it was actually the only legally recognised religion in the kingdom, and it wasn’t just about faith. The Catholic Church controlled the schools, the hospitals. Everything from getting married to being buried had to pass through the Church’s hands, and they decided what was sanctioned and what wasn’t. If the Church disapproved of it, it probably didn’t happen — at least not officially.

In short, it was the unavoidable gatekeeper of all moral authority and all public services.

This power had some deeply established roots. It dates back to the early sixth century when King Clovis I was baptised, kickstarting France’s long-held identity as the ‘eldest daughter of the Church.’ Over time, Catholicism and royal authority became inseparable. French Kings were anointed by bishops, and the Church lent spiritual legitimacy to the monarchy.

The Church wasn’t only spiritually strong; it was economically enormous. It held ‘all the cards’, as Trump might say. It owned about 10% of the land in France and also collected a tithe (a kind of tax) from peasants and landowners alike.

All that wealth made it a target, especially among starving people, already buckling under the stresses and strains of high taxes and food shortages.

Even within the Church, though, things weren’t equal. The upper clergy, such as the bishops and abbots, often came from noble, wealthy families and lived comfortable, even luxurious lives. Meanwhile, the local parish priests were usually poor, and many of them sympathised with the grievances of the people they served.

On top of that, the Church had the power to censor books and ideas. Enlightenment thinkers like Voltaire, Rousseau, and Diderot often clashed with religious authority, and their work circulated quietly or even in secret.

Among the French revolutionaries and many citizens, the Church was seen not as a moral guide but as a substantial part of the oppressive system they wanted to overthrow and dismantle. They were cash-rich but morally bankrupt.

Yes, they certainly did. It wasn’t random; they had specific reasons for targeting the Church.

As the Church was intricately tied up with the monarchy, revolutionaries believed getting rid of kings also meant cutting the Church down to size. Both were seen as pillars of the old regime that needed eradication. You couldn’t strip out one without the other.

New ways of thinking influenced the revolutionaries. Ideals such as liberty, equality, and sovereignty of the people were directly at odds with the Church’s hierarchy and their privileges. The idea that ‘the people’ might decide on their future likely made them shudder, and for a system built on divine authority and inherited power, this type of change was unpalatable. The Church enjoyed the privileges that came with its power, and handing it to ‘the people’ wasn’t part of their plans. The revolutionaries needed them out of the way to achieve their aims.

And, of course, money. The revolutionary government was broke. France was deep in debt, and the Church’s land and wealth were too tempting to ignore.

In November 1789, they nationalised Church property, turning everything the Church owned into state-owned assets that could be sold to raise money to support the Revolution.

Then, there was the issue of overall control. The Church answered to Rome, not to the French people. Revolutionaries saw this as a danger to their national sovereignty. So, in July 1790, they passed the Civil Constitution of the Clergy, which aimed to turn the Church into a state-run organisation. The French would elect Bishops and priests, not appointed by some faceless cleric in Rome. All clergy members were required to swear an oath of loyalty to the Revolution.

Many didn’t like it and refused the revolutionary’s demands, splitting the clergy into two camps. Those who went ahead and swore the oath (known as ‘juring priests’) and those who didn’t (‘non-juring priests’).

The divide was bitter, and from then on, the non-juring priests were seen as enemies of the Revolution, unwilling to toe the line.

At the same time, Enlightenment thinking was growing. Writers and philosophers had been calling for more use of reason and less dogma. The Revolution gave those ideas a foothold in politics, and soon, things went further than most had imagined.

Between 1792 and 1794, France entered a period of dechristianisation. Churches were closed, priests were executed or persecuted, and Catholic symbols were torn down.

During a particularly blasphemous ceremony, the Cathedral of Notre Dame was renamed the ‘Temple of Reason.’

In place of traditional religion, some radicals introduced civic cults, such as ‘the Cult of Reason’ or ‘the Cult of the Supreme Being’, to unite people under new, secular values.

In short, they took a sledgehammer to the Church.

Not quite.

In 1795, the revolutionary government officially declared that the state would no longer financially support any religion and that all religions were free to practice. It was a big step toward secularism.

But it didn’t last.

France was in chaos. Wars raged inside and outside its borders, and the Revolution kept shifting. By 1801, Napoleon had taken power, and he wanted stability. So, he signed a Concordat with the Pope, a deal that brought the Catholic Church back under state control but in a more regulated form.

Under the Concordat, the state would pay clergy salaries, but priests had to swear loyalty to the regime. Catholicism was acknowledged as the faith of the majority but not the official state religion.

It was a compromise: the Church regained status, but the state kept its hand on the wheel.

Even during the brief separation in the 1790s, there were ongoing debates about religion’s role in society.

Some, such as the Catholic priest, theologian and philosopher Nicola Spedalieri, argued for a middle ground. He wanted something along the lines of a confessional state with democratic values. A controversial idea, but it shows how messy the conversation was.

Below are some of the major events and turning points in the church-state conflict during the Revolution:

• Abolition of the Church Tithe (August 1789): The Church lost a significant source of income overnight.

• Nationalisation of Church Lands (November 1789): Land and wealth were seized by the state and sold off.

• Civil Constitution of the Clergy (July 1790): The Clergy had to swear loyalty to the Revolution. Many refused.

• Papal Condemnation: Pope Pius VI rejected the Civil Constitution, worsening the divide.

• Persecution of Non-Juring Clergy: Those who refused the oath were branded counter-revolutionaries and often exiled or executed.

• Dechristianisation Campaign (1792–1794): Churches were closed, religious symbols destroyed, and radical secular cults promoted in their place.

• Formal Separation Decree (February 1795): Officially ended state support for religion. Although, this wouldn’t last.

SYes, but not right away.

After the Revolution, France swung between periods of secularism and religious restoration. The Concordat of 1801 brought back state-recognised religion, and that setup, where the Church had a role but remained under state control, stuck around for over a century.

It wasn’t until 1905 that France passed a formal, lasting law separating Church and state. The Law of Separation abolished public funding for religious organisations and terminated the Ministry of Religion altogether.

Article 1 of the law guaranteed liberty of conscience; Article 2 clarified that the Republic would no longer subsidise or recognise any religion.

The law introduced laïcité, a uniquely French approach to secularism. More than just religious neutrality, laïcité means the state doesn’t just tolerate religion; it actively keeps it out of public affairs. Faith is considered a strictly private matter.

Laïcité is still debated and controversial, especially in today’s multicultural France. But its roots stretch back to the Revolution and the bloody, chaotic, philosophical process of trying to separate two of the oldest and most powerful institutions in the Western world.
