Why do we light candles in churches? History and symbolism

Light as a universal symbol of the sacred

Since the dawn of civilisation, light has been associated with the divine. Long before Christianity, Greek, Roman and Egyptian temples were illuminated with flames in honour of the gods. This association between light and the sacred is deeply rooted in the human psyche: light dispels darkness, symbolises hope and guides souls.

In the Christian tradition, this symbolism takes on a particular dimension. Christ himself is described as the "Light of the world" (John 8:12). Lighting a candle in a church means participating in this light, performing a visible and tangible act of faith.

The origin of votive candles

The tradition of lighting votive candles (from the Latin votum, vow) dates back to the earliest centuries of Christianity. From the 4th century, worshippers lit candles before the tombs of martyrs and the relics of saints. This gesture had several meanings:

• Extended prayer: the candle continues to burn after the worshipper leaves, symbolising a prayer that endures
• Offering: at a time when wax was expensive, offering a candle represented a material sacrifice
• Presence: the flame "keeps company" with the saint or the Virgin before whom it is placed
• Testimony: each lit flame is a visible act of devotion

From the Middle Ages to the modern era

In the Middle Ages, the use of votive candles became widespread throughout Christian Europe. The side chapels of cathedrals and parish churches were lined with candle holders where worshippers came to light a taper while stating their prayer intention: healing of a loved one, success of a journey, gratitude for a grace received.

The Council of Trent (1545-1563) confirmed and encouraged this practice, which became an integral part of popular Catholic piety. Devotional candles became a central element of the worshipper's religious experience.

What theology says

From a theological standpoint, the votive candle is not a magical object. The Church teaches that it is not the flame itself that carries the prayer, but the worshipper's intention. The act of lighting a candle is a sacramental — a sacred sign that disposes the heart to receive grace.

The Catechism of the Catholic Church reminds us that sacramentals "prepare us to receive grace and dispose us to cooperate with it" (§1670). The candle is therefore a support, a concrete gesture that accompanies inner prayer.

This point is essential: it is the light and the intention that matter, not the chemical process of wax combustion.

The four dimensions of the votive gesture

1. The spiritual dimension

Lighting a flame means entrusting an intention to God. The flame — or the LED light — gives this intention a physical presence in the sacred space.

2. The communal dimension

A candle holder filled with multiple lights testifies to the community of prayer. Each light represents a person, an intention, a story. The worshipper entering the church sees they are not alone in their endeavour.

3. The aesthetic dimension

The flickering candlelight creates an atmosphere of contemplation conducive to prayer. It softens the space, creates shadows and reflections that invite introspection.

4. The temporal dimension

The candle that continues to burn after the worshipper leaves symbolises a prayer that does not go out. With a 5-hour duration per press, LumignonLED LED candles perfectly preserve this temporal dimension.

Why LED preserves the essence of tradition

Switching to LED candles sometimes raises legitimate questions. Yet, if we return to the essence of the tradition, LED preserves all its fundamental elements:

• Light is present: it is what symbolises prayer, not combustion
• The gesture is preserved: the worshipper presses a button, as they would light a wick
• Duration is respected: each LED remains lit for 5 hours, like a taper
• Beauty is intact: modern LEDs faithfully reproduce the warm appearance of flame
• Atmosphere is preserved: the contemplation afforded by a holder filled with golden lights is identical

As a Swiss parish priest said after installing his LumignonLED candle holder: "Worshippers still come to light their candle with the same devotion. The prayer has not changed, only the medium has evolved."
