The Church is everywhere represented as one. It is one body, one family, one fold, one kingdom. It is one because pervaded by one Spirit. We are all baptized into one Spirit so as to become, says the apostle, on body.

What's really neat about the Orthodox church is that it's like walking back in time 2,000 years to the time of the Apostles, when they created these services. You walk into that and it's really like... living it. They have maintained the truth ever since the beginning.
