Another thing that might interested you is at the time intense dialogue between Orthodox and Anglicans...sometimes in the 20th century...
Sure it's interesting, and I agree that there shouldn't be anything that was too theologically disagreeable with many Roman Catholic or Anglican prayers in the eyes of the Eastern Orthodox. Yet they are still very different, and still not in communion. Archbishop Rowan Williams always seemed quite too conservative, for many of the more "progressive" Bishops under him.
Some would call The Episcopal Church here in the U.S. quite horrifying, defying Holy Tradition in support of what's novel and new going on in the political sphere under the guise of basic innate rights. They are part of the Anglican Communion as a whole. To be honest, I have the same conflict within myself which is one reason why I'm not sure I could ever be a Roman Catholic. Orthodoxy is a lot better, as they never felt the need to list a whole bunch of items or dogmas which had to be believed. The basics are the 7 Councils, and after that it seems to be up to opinions.
Yet I also know my own innate nature, my own struggles within myself when it comes to a lot of these subjects. I don't understand how a person can be happy, and deny himself so much and live as a monk.. or be celibate for the rest of his or her life. Our ancestors basic instinct was to build a family and procreate, yet Christianity asks us to go from living a human or animal life... to an angelic life. Easier said than done. However the whole message is empowering, that God reached out to humanity and offered a way out of what happened to us as illustrated in Genesis and the Fall.
