Okay, that analogy makes sense. As a technical and taxonomic language, yeah something really stable like Latin or Greek (also used a lot in medicine) is probably best. And yes, I was referring to the Church. Fortunately, Sun doesn't have that kind of influence or power, even if developers as a group can be quite dogmatic.

I wouldn't say that the medical profession uses as a "dead" language that is "no longer under active development". In fact, they invent new words in it all the time.
