I have to jump into this one.
I constantly try to tell people that Roman Catholicism and Eastern Orthodoxy are not the same. Protestants especially, are guilty of making this association. I believe Eastern Orthodox are correct in their assertion that mainline Protestantism and Roman Catholicism are closer to each other than Eastern Orthodoxy and Roman Catholicism. The Eastern way is much different, the theology has developed much differently.
All that being said, I still chose to remain in communion with Rome, because I still believe in the oneness of the Catholic Church.
