Is there a fundamental difference in beliefs of the Book of revelations between Catholics and Protestants?
Yes. All modern day Catholics received the teachings that were authentically handed down by the apostles … one of whom was St. John … the writer of the book of revelation … so Catholics have always understood the symbolism, the dating, the sequences, and at least most of the many nuances of that extraordinary book. There’s no room for nonsense in the Catholic approach, as Catholics were there when the book was received, Catholics were taught the meaning of the book by the apostle John, and Catholics have always maintained high standards for accurate, authentic scholarship and tradition, since ancient times. Protestants seem to think that the bible and the Christian faith magically came into existence during the 15th century, that nothing existed before, and that only a strictly literal interpretation is appropriate, and then only according to the context of their own novel and particular faith tradition. That’s how you get wackiness like the rapture and the “Left Behind” series .
