The Easter Vigil commemorates Jesus' resurrection through rituals including the blessing of a new fire and Paschal candle, readings from the Old and New Testaments, renewal of baptismal promises, and Eucharistic celebration. It begins in darkness and ends in light, symbolizing the passage from death to new life in Christ through baptism and participation in the Eucharist. The various parts of the vigil are intended to help participants unite with Christ's victory over sin and death through faith and remembrance of their own baptism.
