There a has alway been many patriarchs. So what? It's no argument one way or the other.
Actually, it is. Both the Ethiopian Orthodox Church and the Coptic Church - the latter, of course, predates even the construction of Constantinople, claim to be the true church...anong with that of Greece. Now the split-off from the Russian Orthodox claims to be more true to Orthodoxy than the Russian one....There ain't no 'true church', just the One Church - as per the Scripture.
We all get it wrong, but, hey, that's fine: God loves and forgives us.
