The Compline is the last of the four services in the Daily Office. It comes 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. A hymn for the evening may follow the short reading from scripture. The collects may be followed by a time of silence, along with free intercessions and thanksgivings.
Below is a Compline service done at St. Mark's Cathedral in Seattle, Washington. It's a bit longer than most Compline services because they have a men's choir devoted to performing the prayers and songs sung. So, if you can't attend an evening, please enjoy the podcast, and end your day with praise to the Father.
