The name Tenebrae (the Latin word for “darkness” or “shadows”) has for centuries been applied to the ancient monastic night and early morning services (Matins and Lauds) of the last three days of Holy Week, which in medieval times came to be celebrated on the preceding evening.
Apart from the beautiful music that is traditionally part of this service, the most conspicuous feature of Tenebrae is the gradual extinguishing of candles and other lights in the church until only a single candle, considered a symbol of our Savior, remains. Toward the end of the service this candle is hidden, typifying the apparent victory of the forces of evil. At the very end, a loud noise is made, symbolizing the earthquake at the time of the resurrection (Matthew 28:2), the hidden candle is then restored to its place symbolizing Christ’s ongoing presence in the Body of the faithful, and by its light, all depart in silence.
