Tenebrae (Latin for 'shadows' or 'darkness') is a Christian religious service celebrated by the Western Church on the evening before or early morning of Maundy Thursday, Good Friday, and Holy Saturday, which are the last three days of Holy Week. The distinctive ceremony of Tenebrae is the gradual extinguishing of candles while a series of readings and psalms are chanted or recited. In the Roman Rite of the Roman Catholic Church the Tenebrae readings and psalms are those of Matins and Lauds.
Our Tenebrae featured the psalms and chanting of our choir and choristers. The service was a solemn reminder of the sinfulness of each of our hearts, and our coming redemption through Christ.
