Seraphim,
These are very good points. The Church has always struggled to bring people back into the fold and this is exactly why the word Syncretism should be used and not Ecumenism. It is just that many people don't understand the term Syncretism so for the sake of expediency, Ecumenism is more "universal" - no pun intended. This now makes me wonder, did the ROCOR condemn Ecumenism by name in 1983 or Syncretism?
I will take a petty exception to the meaning of the word Catholic and Ecumenical however.
The word Catholic, or "Katholicos", is a hybrid of two Greek words: "kata" which means "according to" and "holos" which means "complete and whole". I'm only writing this because this word is used in many Orthodox books and without its proper definition it is just simply confusing. In short, it really means "the fullness of the faith" or perhaps, "the pillar of real faith according to the Church". Orthodox books never use the word to mean "Universal" because only Westerners think it to mean this. Think about it, the Church began to call Herself Catholic to distinguish Herself from the heresies of the day, why would they call the Church "universal" to do this? But the definition I gave makes perfect sense - not that this needs to be proved, it is self-evident.
Patristically speaking, "Ecumenical" is derived from the Greek root "oixos" meaning inhabited and "nenon" meaning space. Again, patristically, it means of the entire empire, or within the imperial borders. The Romans never really considered barbarian lands "inhabited". When the title was given to the Patriarch in Constantinople, it had a very restricted meaning of
