That blog post is so wrong it’s not even funny. Well, okay…that’s not fair. It’s a little funny. But still, sheesh…don’t believe everything you read, okay? If the non-Chalcedonians could not distinguish between “Person” and “Nature” on account of their being Semitic-speaking people, then how do you explain the fact that:
(1) the Armenians and the Syrian Indians are among them (Armenian is an Indo-European language, so it is related to Greek and Latin, however quite distantly; the Indian Syriacs do not speak any Semitic language natively, and likely have never done so – most speak Malayalam, one of the Dravidian languages).
(2) Coptic is not a Semitic language. It is its own branch of Afro-Asiatic, much like how Armenian is its own branch of Indo-European, indicating a much, much more distant/primitive relationship between it and its nearest relatives.
(3) St. Cyril, whose Christology the non-Chalcedonians hold to (and whom the Chalcedonians recognize as Orthodox) wrote his famous “one nature of the incarnate Word” statement
in Greek (μία φύσις τοῦ θεοῦ λόγου σεσαρκωμένη), as the move to use the common language, which was contemporaneous with St. Cyril’s rule as Patriarch, was not entirely accepted at that time, as it was associated with the White Monastery and St. Shenouda the Archimandrite and other rather rustic people, to put it nicely. There was a feeling at that time that Greek was the language of the learned (and even St. Shenouda had knowledge of it, being educated himself), and Coptic was the language of illiterate slave-peasants.
(4) The non-Chalcedonians’ problem with the Tome and the Chalcedonian definition found acceptable on the basis of its supposed Orthodoxy is, as far as I can tell, that we do not divide Christ into two natures such that (as the Tome says) one nature performs miracles and the other receives insults. “Truly I believe that His divinity parted not from His humanity neither for a second nor for the twinkling of an eye”, as is said during our liturgy’s pre-Communion prayers. It is not a matter of not being able to separate ‘person’ from ‘nature’, but of not accepting any separation of ‘humanity’ from ‘divinity’
(natures) in Christ. Hence we accept the phrasing “from two natures” (hence,
we are not and have never been monophysites), but not “in two natures”, as we do not accept that the natures can be separated in the incarnate Word (and yet they are also not any sort of “mixed” or “hybrid” nature; this is Eutychianism, which we also reject).
Again: We’ve got Indo-European and Dravidian speaking non-Semites among us, so the “well, they’re all Semites, so their languages can’t make those distinctions anyway” characterization falls flat. Our Christology is based upon the Greek theological formulation of St. Cyril. We fully accept and preach Christ of two natures, united at the incarnation without confusion, mixture, or alteration. What exactly is the freaking problem, Mr. Blog Comment guy?
