Tenebrae consists of the Offices of Matins and Lauds said in succession on Holy Thursday, Good Friday, and Holy Saturday. Traditionally, these offices were anticipated, i.e. said the previous evening (tenebrae = “darkness”). This is no longer possible, as the rubrical reforms of Pius XII and Bl. John XXIII have returned these offices to their “proper time” in the morning. I think this has made Tenebrae lose some of its sensual appeal – one does not get the sense of gathering darkness as each candle on the Tenebrae hearse is snuffed if the sun is rising.
