Well, dialogue has led to a greater belief of unity after all. It's a good thing. Have you ever been to a Coptic service, btw?
My sources show that Copts are still heretics, but that most (not all) have rejected Monophysitism. But, of course, my sources are too conservative for you.
I still think the Catholics and Protestants always held jesus in the same way as we have; the Coptcs didn't. Why should Copts receive Eucharist in the Orthodox Church and noth Catholics?
