Originally the Caucasian Albanian and Caucasian Iberian (Georgian) churches accepted Chalcedonianism under the Byzantine Orthodox Rite by the 7th century, while the Armenian church schismed from Constantinople and adopted Apostolic Miaphysitism instead. Had Armenia accepted Chalcedonianism/Dyophysitism alongside Georgia and Caucasian Albania (Arran), then all three would’ve been clerically subjected to Constantinopolitan authority, so there would be no dominance of Armenian Apostolicism over Albanian-Udi Apostolicism; since all three South Caucasian nations would be equally religiously subservient to Constaninople, the Arabs, Persians, and Turks would have a much harder time assimilating and Islamizing the Caucasian Albanian population, as the Caucasian Albanian identity would be far more independent and strongly consolidated, and perhaps there would be upwards of 1,000,000 Udi in the world today instead of the relatively miniscule 10,000 Udi we have in OTL.
