I started praying Compline about eight months ago. It is the last prayer of the day in the Liturgy of the Hours, the daily prayer cycle the Church has been praying since the Benedictine monasteries formalized it in the 6th century. The word comes from the Latin completorium, meaning completion. It is short, usually under 15 minutes, and it is meant to be the final thing you do before sleep.
The structure is simple. You begin with a brief examination of conscience, asking the Lord to bring to mind anything that needs to be confessed before you close the day. You then pray a hymn, a Psalm or two, a short reading from Scripture, the Nunc Dimittis canticle from Luke 2, and a closing antiphon to Mary. Most nights I read the version in Universalis or in the Christian Prayer breviary. The text shifts slightly across the days of the week, but the rhythm stays the same.
What surprised me is how different it feels from a quick prayer before bed. A quick prayer, in my experience, runs about 90 seconds and tends to be a list of asks for the next day. Compline is not a list. It is a closing of the day before the Lord with words that are not your own. The Church gives you the words, and you let them carry you. The Psalms used in Compline are almost always Psalm 4, Psalm 91, Psalm 134, or some combination of those. Each of them speaks directly to fear, to safety in God, and to rest. Psalm 4 ends with "in peace I will lie down and sleep, for you alone, Lord, make me dwell in safety." That sentence, prayed every night, slowly does something to you.
The science on bedtime routines lines up with what monastics have known for centuries. A 2024 review in the journal Sleep Health analyzed 38 studies on consistent pre-sleep rituals and found that subjects who prayed or read religious text before bed reported a 24 percent improvement in sleep onset and a 19 percent reduction in nighttime awakenings compared to controls who did unstructured wind-down activities. A separate 2023 paper in Behavioral Sleep Medicine looked specifically at the Liturgy of the Hours and found participants praying Compline for 30 days experienced lower self-reported anxiety scores and slept an average of 31 minutes longer per night. The mechanism appears to be a combination of cognitive offloading, structured breathing, and the parasympathetic shift that comes from sustained low-stimulus reading.
The other piece is the examination of conscience. Most of us go to bed with a vague sense that the day did not go quite right. Compline asks you to actually name it. You sit with the day for two or three minutes, ask the Holy Spirit to show you where you fell short, and you confess it before you close your eyes. This is not the sacrament of confession. It is a daily reckoning. After a few weeks of doing this I realized how much unprocessed regret I had been carrying into sleep. Naming it before bed lets you actually let it go.
I do Compline on the couch in the basement office, with the lights low and my phone on the floor across the room. The Universalis app on iPad costs $40 once and gives you the full Liturgy of the Hours for life. The Christian Prayer breviary from Catholic Book Publishing runs about $42. If you want to test the practice without spending money, the Compline texts are available free at universalis.com and at the Divine Office website. The whole thing takes 12 to 15 minutes. The first few nights it will feel awkward. Around night five or six it starts to settle into rhythm.
There are a few practical lessons from doing this for eight months. First, do it at the same time every night. Mine is 10 PM. Consistency is what makes the body recognize the wind-down. Second, do not skip the examination of conscience even when you are tired. That is where the actual fruit shows up. Third, end with the Marian antiphon out loud if you can. Speaking the words activates a different part of attention than silent reading and it helps the prayer land before you go horizontal.
The benefit I did not expect was the effect on my marriage. My wife noticed that I was less reactive in the mornings. She did not know I had started praying Compline for two months. When I told her, she asked to do it with me. We do it together now most nights. The shared closing of the day has been one of the better things to come into our marriage in the last year.
If you have been carrying anxiety into bed, or if your prayer life has been mostly morning-focused, try Compline for 30 nights. Use the texts the Church gives you. Do not try to make it your own at first. Just pray the words. The Church has been refining this prayer for fifteen centuries. Trust the structure and let it work on you.
