Mor, have any idea if the services in their prayer books correspond well to ours?
It depends on whether you are talking in general terms or specifically with regard to Bridegroom Matins. For instance, I know from a cursory reading of certain Coptic texts that there are some parallels with Greek texts. Beyond such an observation, I could not tell you much because I am not as familiar with Coptic services as I am with Byzantine services. We do have some Copts here, however, and I hope they come out of the woodwork to answer this one better.
I keep accessing the site referenced above to read the texts, but I get errors each time, and I cannot read them. Is anyone else having this problem?
