What you say is very true. It must also have been very hard or even impossible to use a style and even a vocabulary which would translate into the various languages ( in centuries past as well as today in the periodic updates) in a manner pleasing to the ear or literary taste of the various tongues.
One has to wonder for example ( and there are at least a couple in most Chapters of every book) why such Latin words as " rugitus " would have been selected to describe the cry of Our Lord ( and David ) to the Father in the Passion prayer of Our Lord in Psalm 22 ( Nova Vulgata) in the second stanza. I’m sure Our Lord wasn’t " roaring " or “bellowing.” Surely this was a cry of the heart and mind not made vocally, even for David. Or again the phrase " …torquentes labia …" to describe the verbal taunting of Christ’s enemies in stanza eight. Perhaps though this is a " hebrewism or a similar colloquial expression from one of the other original languages.
One also finds in the various Latin versions a stanza expressed so differently in each that the meaning or translation into the vernacular is quite different. For example in stanzas 2 and 3 of the same Psalm we find in the Clementine " Deus Deus meus respice in me: quare me dereliquisti? longe a salute mea verba delictorum meorum." Whereas the N.V. has “… Deus , Deus meus, quare me derelinquisti? Longe a salute mea verba rugitus mei, Deus meus, clamo per diem, et non exaudis, et nocte, et non est requies mihi…” This is quite a difference in the Latin, and also in the vernacular rendering. However both meanings are quite possibly accurate or at least possible. Haydock’s commentary on this passage is very reasonable. On the other hand the vernacular translation of the N.V. is quite reasonable if you translate " rugitus " as " cry ." In fact my copy of the Psalms from the Confraternity of the Precious Blood translates the phrase in the second way as " …the cry of my words ( I would use " prayer " )…"
What do these facts teach me. First, use the Haydock commentary since he gives an excellent explanation of the text quite often. Secondly, reading the Latin is really an intellectual exercise for most of us and if we want to study Latin we may as well use the Latin Scriptures from whichever approved version we have access to. On the other hand, if we are reading for spiritual edification or prayer we should use an approved translation of the vernacular and there I suppose the Latin admonition " …degustibus non disputandum est…" applies. I use the Holy Text in both ways. I am interested in the Latin and I also like a good vernacular rendering. And for the latter, I would never trust myself to rely upon my own translations from the Latin.
