History of candles in churches: from the Middle Ages to LED candles

The origins of light in places of worship

Light has held a central place in Christian symbolism since the very earliest days of the Church. Christ himself describes himself as "the light of the world" (John 8:12), and this foundational metaphor has profoundly influenced architecture and liturgical practices for two millennia. But before the candle as we know it, the history of religious lighting went through many stages.

Antiquity: oil lamps and early luminaires

In the first Christian communities, which often met in secret in the catacombs of Rome, light came from terracotta oil lamps. These lucernae, fuelled by olive oil, were both practical — one needed to see in the darkness of the underground passages — and symbolic. Light represented the divine presence, resurrection, and hope in the darkness of persecution.

With the legalisation of Christianity through the Edict of Milan in 313, places of worship emerged from clandestinity. The first basilicas were adorned with polycandela, those circular suspended chandeliers bearing dozens of oil lamps. The Hagia Sophia in Constantinople had hundreds of them, creating a luminous spectacle that impressed visitors.

The Middle Ages: the rise of the wax candle

It was during the High Middle Ages that the beeswax candle gradually established itself in European churches. Beeswax, considered pure because it was produced by insects that, according to medieval belief, did not reproduce, acquired an almost sacred dimension. The Church prescribed its use for liturgical candles, distinguishing it from tallow (animal fat), which was deemed impure and reserved for domestic lighting of the poor.

A luxury product reserved for the Church

Beeswax was extremely expensive in the Middle Ages. Only churches, monasteries, and the wealthiest lords could afford it in quantity. Abbeys often had their own apiaries, and wax tithes were a common levy. The chandler, a craftsman specialising in candle-making, was a respected profession governed by strict guilds.

The Paschal candle, lit during the Easter Vigil, became the quintessential liturgical symbol: large, imposing, it burned throughout Eastertide and represented the risen Christ illuminating the world. This tradition, codified in the 7th century, continues today in all Catholic churches and many Protestant ones.

Votive candles: the light of prayer

The practice of burning a candle as a sign of prayer developed from the 12th century onwards. The idea is simple and powerful: the worshipper lights a candle before a statue of a saint or an icon, and the flame continues to "pray" in their absence. The gesture is usually accompanied by an intention — healing of a loved one, giving thanks, requesting protection — and a financial offering placed in a collection box.

This practice, at the crossroads of popular devotion and theology, enjoyed immense success. The side chapels of Gothic cathedrals were lined with rows of candles whose flickering light created a unique atmosphere of contemplation. The candle trade became an important source of revenue for parishes — an economic reality that persists to this day.

The Renaissance and modern era: industrialisation of the candle

From the 18th century, the discovery of stearin (1823) and then paraffin (1830) revolutionised the candle industry. These materials, far cheaper than beeswax, enabled mass production. Votive candles became accessible to all worshippers, and their use became considerably more widespread in churches.

But this democratisation brought new problems: paraffin candles, derived from petroleum, produce more soot and smoke. The walls, vaults and artworks of churches suffered. Heritage restorers raised the alarm about the damage caused by centuries of combustion inside often poorly ventilated buildings.

The 20th century: first challenges

In the 20th century, fire safety concerns were added to questions of heritage conservation. Several dramatic church fires across Europe — including the Lignon church fire in Geneva in 2014 — highlighted the inherent dangers of open flames in old buildings filled with combustible materials.

At the same time, the decline in religious practice in Western Europe led to a reduction in parish staff. There are fewer sacristans, fewer volunteers to monitor candles, clean wax and ensure safety. Churches remain open but increasingly without supervision.

The 21st century: the advent of LED candles

The emergence of LED technology in the 2000s opened a new chapter in this thousand-year history. The first LED church candles were rudimentary — cold light, plastic appearance, lack of realism. But the technology has progressed rapidly.

A credible and respectful alternative

Today, modern LED candle holders like LumignonLED offer a visual experience that remarkably approaches the traditional candle. The warm light, the gentle flicker of the LED flame, the arrangement in rows on a metal stand — everything is designed to preserve the atmosphere of contemplation.

The worshipper's gesture is preserved: instead of striking a match, they press a button. The intention remains the same, the light comes on, prayer accompanies the gesture. Each LED candle shines for 5 hours, recalling the burning time of a traditional votive candle. And the LEDs last 50,000 hours — decades of use without replacement.

The push-button system: trust rather than a coin slot

A distinctive aspect of LumignonLED deserves highlighting: the choice of a trust-based push-button system rather than a coin mechanism. In a place of worship, lighting a candle is an act of devotion, not commerce. The worshipper lights their candle freely and deposits their offering in the collection box if they wish. This philosophical choice deeply respects the spirit of the votive gesture.

Tradition and modernity: continuity, not rupture

The history of candles in churches is one of constant evolution. From Roman oil lamps to medieval beeswax candles, from industrial paraffin candles to 21st-century LEDs, each era has adopted the best available technology to carry the same symbolism: light as an expression of faith, hope and prayer.

Switching to LED candles is not betraying tradition — it is perpetuating it with the means of our time, adding safety and environmental respect. The parishes of Grolley, Uvrier, Le Crêt, Villarepos and Yvoire have understood this: the gesture of light remains intact, minus the risk.
