You gotta be kidding? Entire volumes have been written by Protestant scholars refuting age old Catholic doctrine. Protestantism, after all, is based on the refutation of the authority of the pope. After his initial complaints about some legitimate clerical abuses, condemning the office of the Pope and his teaching authority became Luther's constant, divisive theme and that's how he came to invent his doctrine on "sola scriptura" and "sola fide", (Bible alone and faith alone). According to Luther, (who was a veritable pope unto himself through his own teaching authority), the Bible was all Christians needed for their authority. Nevermind that for 1,400 years there was no printing press and Bibles were rare because they had to be hand printed by specialized monks. Nevermind that even up to Luther's times a great many people didn't even know how to read. Nevermind that for the first 400 years of Christianity there was no 'New Testament' that appeared under the cover of one book. Nevermind that for the first 90 years of Christianity the Bible hadn't even been completed yet. All these poor Christians who predated the Bible's completion, or who never saw a Bible because only a few thousand existed before the printing press, or who couldn't read, they all went to hell according to Luther's theology.
Luther was all full of himself --- the Christian Church was a TEACHING Church from the beginning, as the Apostles and disciples taught by mouth, so did their counterparts throughout the ages. The Church never was intended to be a book club. In fact, the Bible itself condemns this idea. 2 Peter 1:20 and 2 Peter 3:16 warns us NOT to interpret the Bible ourselves. And Jesus commanded the Apostles to "go and PREACH TO all nations",(Mark 16:15) not "go and write a bible and let them glean from it as they wish".
