The Easter Vigil begins after sunset on Holy Saturday and continues into the early hours of Easter Sunday. It's considered the most important liturgy of the year, marking the turning point of the Sacred Paschal Triduum, the Passover of the new covenant, and Christ's passage from death to life. The vigil begins with a fire being blessed, and from that fire, the Paschal Candle (Easter Candle) is lit, symbolizing the light of Christ. Liturgy of the Word includes a series of readings from the Old and New Testaments, recounting the history of salvation. The Mass concludes with the celebration of the Eucharist, where Catholics receive the Body and Blood of Christ. The darkness of the church before the Service of Light and the subsequent illumination represent the darkness of death and the light of Christ's resurrection.
