I know its not my place but I think one way to re-unite the Catholic faith with the Orthodox would be to hold another ecumenical council. There are a variety of reasons to call one. The first being the spread of hostile religions that persecute Christians throughout the world. The second would be strengthening the ties between the various churches. The third would be discussing the various doctrines each church carries and their affects on the faithful. A key issue would be the discussion of why so many of the faithful tend to become lax in the faith; many ultimately leaving it all together. I admit I have alot to learn but I feel that the Greek Orthodox Patriarch should be the one to call it and head it as the issue at his Patriarchal See is in the most danger. The question is how can we suggest this to him without appearing as a bully? They’ve gone through enough hell in Turkey.
