In the Catholic tradition, individuals light candles for memorial purposes or to signify intercessory prayers for others. This practice is neither commanded nor prohibited in Scripture, yet it can be an outward expression of an inner petition. For example, if someone is praying for a family member or friend, the candle becomes a physical token of that prayer commitment even after the devotee has departed the sanctuary.

Lighting a candle in someone’s memory or while praying for them can remind the believer to bring that intention persistently before God.  The purpose of lighting a prayer candle, while not explicitly taught as a requirement in Scripture, can be understood as a meaningful act reinforcing biblical themes of light and devotion.
