Unfortunately, Bible Christians know little if anything of the first fifteen centuries of Catholicism
If you had to choose only one or the other would you choose the Bible or the traditions of the Catholic Church?
Before the Bible, there existed the Church. You pose a false choice. The infallible Church that pored over and interpreted the hundreds of written texts at the time and cross referenced it with the oral tradition, and after centuries of checking and cross-checking gave us the authoritative canonical text of the Bible in the Synod of Rome in AD 382. That version has since never changed. Besides, the oral word of God (Jon: 21: 25) did not disappear into the desert air. The words of the Bible (like any written text) must be understood and interpreted by those who were closest to Christ and his disciples and not through the lens of 21st century literalists.
