Well I think it could still technically be on topic if the terms were compared to the Eastern Orthodox view and explained how they differ from eachother, and how it is seen as right/wrong from the Orthodox perspective. I'm not really sure how to contact the mods. I don't use this forum often, I mostly just lurk and read what other people are saying.
I mentioned that Syriac Orthodox use the term because i saw this mentioned by an Oriental Orthodox on a different site, although they didn't give an explanation as to how they were used or how common it is. But it's really difficult to find any materials on the Church of the Easts theology, or on specific theological views unique to different Orthodox jurisdictions. Mostly just due to language barriers.
I've tried looking up "kyana" and "Qnume" before and all I could find was a vague explanation. I was basically told that the CotE gets the explanation of why the Trinity is both three yet one better, because the three persons are actually the same exact reality, except when considered in number. Almost like they are different instantiations of one reality, but not in a modalistic way where they are just modes of one nature, but in a more separate way. I'm not sure how accurate this actually is to their official view, but it seemed to make some sense, although Saint Maximus says that the Trinity is not simply counted numerically, so maybe not. But then hearing that Syriac Orthodox might use the terms as well confuses me, since I'm certain they would say that they don't have the view of the Church of the East on anything.
