Tenebrae is a chance to focus on the loss felt by Jesus' followers caused by his betrayal by Judas, his death on the cross and his burial in a tomb. This service reflects on the different shadows cast by these events, and this is symbolised by 13 candles. One by one each of these candles are extinguished leaving the church in darkness. This service reminds us that Jesus' suffered these shadows so that we might be restored to God and have eternal life.
