The New Jerome Biblical Commentary (c.1993) points out that there are very few official pronouncements about interpretations of the Catholic Bible.
So, undoubtedly, there is a slant by various translators and those who provide commentary.
I have been just re-reading the document on The Jewish People and their Sacred Scriptures in the Christian Bible" put out by the pontifical biblical commission, around 2005 (see here
ewtn.com/library/CURIA/PBCJWSCR.HTM).
This relatively recent document takes the documentary hypothesis for granted (“four sources”) and, it endorses the historical-critical method as valuable to understanding the topic of the paper.
That said, I would not be surprised to find footnote commentary to have some prejudice of some sort in it. Even the document referenced above has that tone to it, of Biblical material being redacted and having words attributed to Jesus, Mary, etc.
I spend time in Jewish commentaries, and Jewish scholars, from the same historical-critical point of view, say the same things about words and speeches being attributed to Moses, for example.
Commentaries are much more detailed than study bibles, as I have found. They can often incorporate alternate points of view about something. The ancient and modern Jewish commentaries are much more open to putting varying, even contradictory, opinions side-by-side, for the reader to consider.
That is one reason, alongside the whole issue of translation, why people who have already posted here have several Bibles for comparing. And, well they should.
In one of the opening visions of the book of Ezekiel, he sees a heavenly figure described as having a “writing case” on his belt or sash. Writing Case? Time to check the Septuagint (as in the Orthodox Study Bible) where it is translated more convincingly as a belt of sapphires. Some of us amateur, self-taught Bible readers have to pay sooner or later, one way or the other, to get through some problem like this one.
