I've been doing some reading about the Russian Old Rite recently, and while reading about the various priested hierarchies, I discovered that the Russian Old Orthodox Church (the Novobyzkov hierarchy) spawned a breakoff with the formidable name of the Slavo-Georgian Iberian Old Orthodox Church (bold for extra impressiveness). Apparently this small group uses the Georgian service books used prior to the 1800s, when invading Russians presumably brought the Nikonian reforms along with Russianising practices. Does anyone know anything about this Old Rite Georgian tradition? To what extent does it differ from the Russian one (since Georgia follows the Greek liturgical tradition rather than the Slavic)? Where can I find out more about this?
