Please join us for the Tenebrae service tonight, Wednesday, April 17 at 8 pm at the Co-Cathedral of St. Thomas More. Tenebrae (Latin for shadows or darkness) is that part of Liturgy of the Hours that was celebrated in the evenings during the Triduum and dates from the 7th or 8th century. The mood is somber, quiet and reflective. The distinctive feature of the service is the gradual extinction of all the lights in the church as we contemplate the temporary triumph of the prince of darkness over the Light of the world.
