Compline is descended from the night prayers said before bed at the end of the monastic round of daily prayer. Compline is a simple office including a confession of sins, one or more psalms, a short reading from scripture, versicles and responses, the Lord's Prayer, collects which ask for God's protection during the night to come, and the canticle 'Nunc dimittis.' This ancient service is sung by a schola cantorum in the darkness of candlelight and lasts approximately 20 minutes. Reception will follow.
