Paschal candle
Once the candle has been lit, it is carried by a deacon through the nave of the church, itself in complete darkness, stopping three times to chant the acclamation 'Light of Christ' (Lumen Christi), to which the assembly responds 'Thanks be to God' or 'Deo Gratias'. As the candle proceeds through the church, the small candles held by those present are gradually lit from the Paschal candle. As this symbolic "Light of Christ" spreads, darkness is decreased.
