I need some clarification, since it's general revelation, which is ought to be trusted. False Messiahs and prophets? It was fulfilled. It's all general revelation, but there is a need to filter inaccuracies. Like, the claim about Russia comes from the Kievan Synopsis, which contains a legend about Mesech. I looked up for the Meshechite races... and there was no Russians among them. Also, if the Russians were not Japhteic, then which race they come from?
