The Office of Matins and Lauds this morning, according to the Divine Office prior to the debased modernist Liturgy of the Hours, is what is known as "Tenebrae." While it is now (since 1955), read or sung at the normal times of early morning, it was prior anticipated. Therefore, Matins and Lauds of Holy Thursday occurred on Wednesday night, after Vespers, and so on. The word "tenebrae" is from the Latin for shadows. A hearse, a candelabra, was placed in the centre of the sanctuary, The candles were extinguished one by one after each psalm and reading until only one remained, the Christ Candle which was then removed to a place behind the altar where only shadows were cast, from it. The choir would then bang their feet or pound their stalls in a great noise signifying the chaos of the universe at the betrayal and death of the Lord.

The Readings today are profound. They are indeed also prophetic. Not only for the days of evil which came upon Our Blessed Lord, but as one reads and prays them, one realizes that they are speaking to us, today. The very conditions of the Church today echo the Prophet Jeremias' Lamentations, St. Augustine's Treatise defines the traitors of then and now and St. Paul's Letter makes clear the condemnations that are now dismissed as meaningless.
