We can make it even more interesting, after all the Catholic Church is a rather large Church that's been around for a long time. She uses both!
Consider the Latin Vulgate translated by St. Jerome. He caused quite a stir in the Latin speaking world in his day by specifically translating the Old Testament into Latin directly from the Hebrew rather than the Greek Septuagint!
That's one reason, for example, that you will find certain psalms off by a number between the East and the West, etc.
Go figure.
Really? I wondered about that!
