Indeed. The Coptic Orthodox liturgy is very beautiful. It seems like the Copts prostrate more often than us Byzantines (though where I come from, there are pews in the churches, so prostration's very hard or impossible to do on a normal basis ). I've never been to a Coptic church, though I know a few very basic things about their rite--such as the use of cymbals and triangles during divine services, which we can see in the video. There's a world of diversity among the various Apostolic churches...
