Burning Candles on the Evening of Holy Thursday

On Great Thursday Orthodox Christians bring home from the service [of the reading of the Twelve Gospels] burning candles or a lantern with a flame.This is simply a beautiful Russian tradition. Matins for Great Friday is served on Thursday evening, during which the so-called “Twelve Passion Gospels” are read, in which the story of Christ’s Passion is related. Parishioners stand with lit candles for the entirety of the service, which they then take home. At home one lights one’s icon lamps from these candles. There exists the pious custom of maintaining this Thursday fire in one’s icon lamps until Pascha. In olden times the soot from burning Thursday candles was used to draw crosses on doorways.
The Thursday fire is a symbol of the enlightenment of the world with the light of the teaching of the Gospel. - Igumen Pakhomy (Bruskov),
