This summer I have the chance to delve into either Latin or Classical Greek in exchange for some Hebrew lessons. The problem is that I am having some trouble deciding. I know that classical Greek will bolster my current Koine Greek and help in the area of the church fathers, but Latin will also help in that area. Not only that, but I am fascinated with Catholic liturgy, so Latin would be helpful there.

If you could choose only one, which would you choose between Classical Greek and Latin, and why?
