[Deo volente]

There are countless Catholic commentaries on the Bible, from the early Apostolic Fathers all the way up to the present. Several lifetimes would not be enough to read through all of them.

There is a new 17-volume commentary being produced right now, with the approval of the Pope:

The argument that it is somehow wrong that there has not been a commentary produced by the Vatican and declared infallible, ex cathedra, is bogus. Very few pronouncements of the magisterium are declared infallible in an explicit way.
The idea that for something to be authoritative it must be pronounced ex cathedra is a faulty premise.

There is no official magisterium commentary on the entire bible in 2000 years ..If the church is the only one that can interpret scripture then the church should have an infallible commentary of the entire scriptures .

What you have is bits and pieces done by various authors all giving their OPIS

There is no comprehensive commentary tying together ALL of the OT with the entire NT ...so Catholics have a puzzle missing many parts..
