From Compline to Morning

The Grand Silence, sometimes called the Great Silence, is the extended period of enforced silence observed in Benedictine, Trappist and several other Western Christian monastic communities, running from the close of Compline, the last of the day's canonical prayer hours, until the community gathers again the following morning, a nightly practice rather than an occasional one, structured into the ordinary daily rhythm of monastic life rather than reserved for special occasions or retreats alone. The practice traces its authority to Chapter forty two of the Rule of Saint Benedict, the sixth century foundational monastic rule that continues to govern Benedictine and Trappist communities today, which explicitly instructs monks to observe strict silence after Compline, grounding the nightly discipline in a document with continuous, documented institutional authority across roughly fifteen centuries of Western monastic practice rather than treating it as a later addition to the tradition.
