The University of Navarra is a private university located on the southeast border of Pamplona, Spain. It was founded in 1952 by Saint Josemaría Escrivá de Balaguer, the founder of Opus Dei, as a corporate work of the apostolate of Opus Dei.
I can't speak highly enough of the Navarre series. One of my two main go-to commentaries. Not a line-by-line commentary, but very substantial in especially culling the spiritual meaning of various sections and passages, heavily relying on the Fathers and St. Josemaria. I often come across insights here that I have not come across elsewhere of had not considered myself. It is not uncommon for the commentary to take more space on the page than the text of Scripture. Outstanding also are the five introduction sections (to the Bible, New Testament, Gospels, Mark, and dates of the life of Jesus). A gem of a series that all serious Catholics should have handy.
I used/read the commentary when I wanted clarification or to go deeper on something. And the commentary was always enlightening and spurred me on to deeper wonder, faith and piety.
