I was just curious about how long (this is to all non-Chalcedonians) your Liturgy goes.
With regard to how long our liturgies last, it depends on the Church.
I've been told the Armenian Church uses a version of the St. Chrysostom liturgy, with some of St. Basil's mixed in. There are also some other influences, including some things borrowed from the Catholics during the Crusades. Typically, Armenian liturgies will go for two, or two and a half hours.
I think the Coptic liturgy is from St. Basil. The Coptic liturgies I've been to will last anywhere from two to three hours. They also have another rather short liturgy that was recorded by St. Cyril, but attributed to St. Mark. That one is not used so much. I've only been to one such liturgy.
The Syriac Orthodox Church uses St. James. It has been a long time since I have been to a Syriac Church, but I seem to recall the liturgy being at least a couple of hours long.
I don't know who the Ethiopians attribute their liturgy to. I know their traditions regarding chant, though, come from St. Yared. Their liturgies usually go for four to five hours. At least that is my experience here in Los Angeles.
