Diaconia:
In our days I would say that Greek is the most valuable for Scripture study.
My priest agrees. He was saying that Latin is somewhat ambivalent. A statement may be able to be interpreted in one of several different ways. He was giving me examples of this, which went over my head, since I have not much Latin. Then he gave examples of how a statement could be read backward and it could mean the same thing. You really have to know the context of a Latin sentence to interpret it correctly.
Then he gave some similar examples of Greek (also over my head) and said it was a much more exact language and, therefore, more valuable for scripture study.
I had sat down with our priest to clear up a few things about the faith and we ended up having a talk about languages. Well, HE talked about languages while I sat somewhat spellbound at the extent of his knowledge!
