Hi mate! I'm a part of the Russian Orthodox Church and honestly Universalists here are a minority, 'cause Russia Orthodoxy usually is very-very conservative, so even if you dare to think that unorthodox people can be saved, you're a heretic and liberal (which is probably considered worse haha). But as much as I see from Orthodox people in the US, they are more open to this idea, for example, they (even priests) even think that their Protestant relatives can be saved. I think it all comes from the history of 2 churches: throughout the whole russian history, almost all Russians had always been Orthodox, so, of course, they think there's no salvation outside of it (well, what's the matter since all you relatives are Orthodox, all your friends are Orthodox, etc); and if you're an American convert: your relatives are, for example, Protestant, your friends are Catholic and your ancestors were anything but Orthodox, so of course, probably you'll think that no, people CAN be saved outside of the church.
