Cronos from #796: "3. The Coptics DID break away in terms of a schism --> it was not power-politics, if you read the details of the councils the issue was over the nature of God "

According to Coptic history, it was Copts who held fast to their original beliefs, and the Orthodox at Chalcedon who wandered off into heresy.
Of course, I have no dog in this fight, but it does seem to me Copts have a stronger case.

Again, my argument is that none of these differences in theological opinions could matter a whit in the Eyes of Christ, but Christians rejecting and persecuting other Christians over such disputes must surely force out of Him tears of blood.

“but it does seem to me Copts have a stronger case” ==> why do you say that? Actually, I would modify what I said to a mutual schism — there was a problem of language to a large extent.
