Just a small caveat, you have to be careful about an evidentiary standard, so to speak, that’s as high as the one you propose. Very few biblical scholars, Catholic or otherwise, are fluent in the ancient languages. It’s entirely possible to get an advanced degree in Sacred Scripture without being fluent. One merely need to demonstrate a high degree of working knowledge. I have a Master’s in Theology with a Scripture concentration, and while I had about three semesters each of Latin, Greek, and Hebrew, I’m not able to simply converse in each one of them. I am well enough equipped in each to know how to work with them, to do research, to look things up, and to talk about nuances in meaning. Most priests, even if they’ve never had a class in Greek or Hebrew, know enough about the finer linguistic points of the texts to at least preach about how those things bear on what is being taught. We’re required to take a lot of scripture classes in seminary, and there, even for one who does little to no instruction on the languages, still picks up the facts of how certain things have to be interpreted.
