I’m aware of the Eastern Rite churches. I don’t think that’s what was being discussed though. I am fairly sure the original question pertained to Eastern Orthodoxy.

NRx is correct - the question pertained to Eastern / Greek Orthodoxy. You'll note how few Catholics were willing to answer that question, however.

What is this "question" of which you speak? About population counting, or theology? There are about a billion Catholics in the world, and about 350 million or so Orthodox. The billion Catholics doesn't include the 350 million Orthodox.

Is that the question you wanted answered?

Ask an Eastern Orthodox if a Roman Catholic can receive communion in their church.
