Therein lies your mistake. That's the way "authority" works.
Furthermore, comparing a helpful, authoritative, clarifying addition to one whose only purpose is to promote a heretical doctrine no one ever heard of for 1500 years is hardly apt.
When will Protestants get it through their heads Catholics pointing out Protestants don't practice their own principles does not obligate Catholics to practice Protestant principles?

And herein continues Rome's error. Rome is not able to add to Scripture what is not in Scripture.

Except people have heard of by faith alone previously as demonstrated. For some reason Roman Catholics seem to gloss over the evidence presented.
The so called "helpful, authoritative, clarifying addition" is none of what is claimed. It adds to the text something not in the manuscripts.
That clearly goes against admonitions in Scripture to not add to the text.
And as noted, the NABRE is the only translation to do so.
And as noted, the translation noted by the Msgr is incorrect and the words interjected by the NABRE simply are not in the Greek manuscripts and goes beyond what the passage is dealing with.
This is not the first time Rome has taken great liberties with the texts and is not the first time Rome has committed great error in doing so.
