Raymond Brown wrote in his book "Crises Facing the Church"
about orthodox Catholics who wanted an end to heretical catechisms,
“They do not hesitate to denounce catechisms approved by the Bishops with an incredible demand to return to the Batlimore Catechism”
He was speaking about the heretical catechisms that were so prevalent 15 years ago that some bad bishops had been approving at that time.
But in rejecting a return to the Baltimore Catechism, Raymond Brown obviously rejected clear teachings that had been handed down from the apostles, in other words, these were the fundamental teachings of the Gospel that they taught and preached. These are simply the basic teachings on the Trinity, the Creed, Sacraments, Commandments and Prayer to be which came from the apostles, and which did not come from exegesis of bible verses. These basic teachings are part of the hierarchy of truths that the Church says are central to the Gospel.
The General Directory for Catechesis states about this hierarchy of truths:
This is organized around the mystery of the Most Holy Trinity, in a christocentric perspective, because this is “the source of all the other mysteries of faith, the light that enlightens them”. (389) Starting with this point, the harmony of the overall message requires a “hierarchy of truths”, (390) in so far as the connection between each one of these and the foundation of the faith differs. Nevertheless, this hierarchy “does not mean that some truths pertain to Faith itself less than others, but rather that some truths are based on others as of a higher priority and are illumined by them”. **
Then it goes on to state this hierarchy of truths, after the Trinity, is centered on salvation history, then the Creed, Sacraments, Commandments and Prayer.**
The Baltimore Catechism, which was put out by the bishops in the 1800’s, simply clearly and explicitly presents these basic truths of the Gospel that the apostles handed down by their teaching and preaching, the same truths taught today in the Church.
It would seem to me, that by rejecting the Baltimore Catechism, which only taught the basic teachings of the Gospel as the Church has always taught from the time of the apostles, Raymond Brown was rejecting the fundamental truths of the Gospel, thus could not even remotely be Catholic, and possibly not even Christian.
To bad for years he was portrayed as the Guru on biblical exegesis and scriptural commentary, and as an editor of the Jerome Biblical Commentary, his teachings were given the highest respect by many leaders in the Church. Of course, now we can see why his exegesis was so off the wall. He simply rejected the truths handed down in Sacred Tradition by the apostles and their successors.
