As a catholic, universal church, we ought to all be praying with the same words. We all have different languages. On top of that unity does not imply uniformity. Change the words and you change the meaning. And when you change the meaning, you change the faith.
Translators always change words.
It's part of the idea. There is no word for word translation from Hebrew to English. There's room for artistic, theological, literary interpretation. Not any more. The position that a general use of the word is exclusive is pure hogwash.
