Tenebrae Service "Worship in Shadows"

Tenebrae is a religious service of Western Christianity held during the three days preceding Easter, and characterized by gradual extinguishing of candles, and by a "strepitus" or "loud noise" taking place in total darkness near the end of the service. 

This service is held to commemorate the suffering and death of Jesus, beginning with his journey to the cross and ending in the darkness of the tomb.
