I am speaking for myself and not the Catholic Church, although what I am going to say has some support within the Church. I believe that there is a hierarchy between and within Scripture. The words accredited directly to Jesus have the highest weight. The descriptions of the eye witnesses to Christ closely follow. The Old Testament gives us context and the Letters of Paul give us clarity. Next are other contemporaneous works not found to meet canon like the gnostic Gospels and historical works.
Jesus chose to speak to us in clear and simple words. I believe that if everything else but the Beatitudes was stripped away we would still have out path to salvation. I personally don't give much weight to the Book of Revelation because it is too cryptic and subject to misinterpretation..
Paul said he was taught by Christ Himself. That’s like saying, Well I believe Ezra, but not Jeremiah so much.” Revelation is spoken bt christ. It’s unbelievable, to me, a believer, that you don’t believe Christ’s revelation. Yet as a Catholic, you apparently have no problem with the words and traditions of men.
