orthodox and catholic

orthodox means straight/normative (orthodontics, orthotics, orthoptics - straight teeth, straight [limbs], straight vision) teaching/opinion (doxa)

catholic means with respect to the whole (kata + holos)

so unless there is the either explicit or implicit linking of orthodox with eastern or greek or coptic, it just means true or right, teaching.

likewise, unless catholic is qualified by roman or marionite, it just means, this is the same thing all people believe.

i don't know whether we'll ever be able to retrieve either of these words for regular use, but it would be nice to be able to use them without qualification or substitution for wordy or unequal equivalents (such as universal or apostolic).
