Hmm, not to pee on your parade or anything, but I was not aware you could convert to the "general auspices" (not sure what this means in this context) of something as vague as "eastern Christianity" (or, if you can, you could do that and retain whatever Buddhist things you do). Were you baptized in a particular church? Are you under a canonical Orthodox bishop? It's hard to tell what has actually happened here, so I don't know what I'd be congratulating you for.
