Thanks, fellas. All three references were great (in fact, I had forgotten I own St. Gregory of Nyssa's Moses). I wonder though, which school of thought is more prevalent, or accepted, within Eastern Orthodoxy?
Long story short: both are incorporated along with other interpretive methods, but with typology playing a central role as far I can tell in terms of its role it plays in early exegesis and popular interpretation within homilies and the like. (If you can actually argue for a distinction between typology and allegory.)
If you want a single volume introduction to hermeneutics (something close to my heart) within the Orthodox tradition, I cannot more highly recommend:
Scripture in Tradition: The Bible and Its Interpretation in the Orthodox Church - Fr. John Breck
http://www.amazon.com/Scripture-Tradition-Interpretation-Orthodox-Church/dp/0881412260Hermeneutics is understanding within the scope of the entirety of Tradition and living practice and Fr. John does a tremendous job of doing the impossible in attempting to give an account of how this happens with Eastern Orthodoxy. People can always complain about any attempt to cover such a vast subject within a single volume by a single author, but I doubt many on this board would steer you away from this text.
It is probably available from your library.
