Dear Tim,
Regarding the Greek, I'm not an expert, but here is what I understand:
Modern liturgical Greek is Koine, which was the common Greek of the New Testament era. The "high" Greek of that time would have been classical or Attican Greek.
Nowadays, the Greeks speak demotika and katharovousia (both probably misspelled by me). The government has adopted the demotika as official, while the conservatives, royalists, and upper class tend toward the katharovousia. It has become a real class and political distinction.
As I understand it, the Koine Greek of the scripture, canons, and litugy is closer to katharovousia than demotika is. Demotika is vastly simplified.
Liturgical Albanian and modern (Tosk/Southern dialect) Albanian are virtually interchangeable, with small revisions to liturgical books occurring in the 1960s and 1990s.
In Christ,
Andrew
