Well for me personally Catholic or Orthodox does not say that it is probably the Roman Catholics that are right since I actually became more used to refer to the Eastern Orthodox Church as the Catholic Church since the EOC also refers often to herself in older documents as the Catholic Church you can check the Confession of Dositheus the Orthodox patriarch of Jerusalem which dates from 1672 it often uses Catholic Church the Confession does not even use the expression Orthodox Church except in the notes added by modern scholars it uses the word Orthodox only when referring to the Orthodox faith or the Orthodox worshippers However I realize now that you are probably correct in assuming that other users and readers could have thought of the Roman Catholic Church instead
