I used the Coptic Compline Sunday night - took me about 25 minutes to pray.
And yes, the Agpeya prays all 150 Psalms on a daily basis.
And from what I can tell there is no cycle - the office is the same every day.
So far I’ve used the Coptic versions of Prime (the equivalent to Lauds), Vespers and Compline… And let me tell you. When you finish praying these Coptic offices, you feel like you just ran a spiritual marathon! This Office is not for the faint of heart or the spiritual novice!
I haven’t dared try to use the Midnight Office (Matins/Vigils) yet - it looks like it will take a little over an hour to pray and is just so intimidating!
Remember, this Coptic Office was developed by the great Desert Fathers like St. Anthony - it’s nothing to sneeze at.
If you want to pray every one of the hours, you will spend about 5 hours of your day in prayer. (Although when reading about the Benedictine Rite, I read that at one time their Office was so massive it would take 12 hours a day to pray).
Much different from the Roman Rite where you can pray every one of the hours in under 1 hour.
The OF Roman Rite Office, to me, feels like it was specifically designed for secular, busy parish priests and laity with jobs and families in mind - nothing wrong with that. But for those of us who want something a bit “heavier” and have more time on our hands, it’s great the Church offers us different versions of the Office such as the EF or the Coptic or the Byzantine Horologion. I’m still looking forward to the Anglican Ordinariate Office! I’m also excited for the new translation of the OF Roman Office.
I guess I just love the Liturgical Hours. I feel like they are such a neglected treasure - I see people constantly talk about the Rosary, yet many of them don’t even know what the office is - really it’s a shame, since the Church teachers the Liturgical Hours are the pre-eminent and most efficacious prayer the Church has to offer.
