Georgians are usually Christian, just like the Russians, Greeks, Serbians, Romanians and Ukranians. As for the Georgians there are a few in my Church in New Jersey.
Stalin was a Georgian. Sooner or later, there's gonna be a lot of trouble with the former Soviet countries in the Caucasus Mountain area. Christian/Muslim issues, battles over the untapped oil reserves, etc., It's all simmering now just ready to explode, and Iran will certainly play a role in lighting the final fuse.
Byzantine or Orthodox?
