So, I'm an undergrad coming close to finishing, and I intend to pursue a grad degree in either theology, Russian Studies, or possibly linguistics, when all is said and done. For a Rus Studies PHD, it is almost imperative that one have excellent Russian (I have this), excellent French or German (I speak fluent French), working Ancient Greek or Latin (one year of Greek in 9th grade, a few years of Middle School Latin, i.e., I know hardly anything of either language), and one addl Slavic tongue. For theology, Greek or Latin is a must, if not both.
My inkling is to begin taking Ancient Greek in September, as I've always wanted to do it, anyway, but I was curious, how useful would this be in terms of the Septuagint, the Fathers, etc.? These texts are mostly in Koine, correct? How does one transfer to another? I know that ancient-modern Greek is a total no-go, but I don't know much about Koine.
