The problem of the Bible versus 'tradition' can be viewed as a kind of 'Which came first, the chicken or the egg' problem.
When Protestants began speaking of 'Sola Scriptura' (Bible only) as a rule for doctrine and conduct, they perhaps did not immediately perceive the problems that would inevitably come after such a position was proposed. Nor were (Roman) Catholics initially prepared to properly refute Protestant excesses, anymore than Protestants were able to effectively combat Roman Catholic errors.
All these problems came historically in a certain order, and probably could only be dealt with one at a time.
Thus the tampering and eventual rejection of the Septuagint (Greek O.T.) by the non-converting Jewish authorities led the Christians to preserve and define their own Old Testament canon and text.
And the rejection of most of the New Testament by Marcion forced Christians to think and act more carefully about the Canon and text of the New Testament.
The corruption of the church in the Middle Ages (admitted by Catholic scholars) again led to a grassroots reaction by Christians, yet in each of these cases, ideas were first proposed in primitive forms, and not only details had to be practically worked out, but new problems had to be solved, and wild notions tamed by reason and experience.
So also with the idea of 'Scripture Only' as a guide. Some of the problems immediately arising were,
Which Scripture is really Scripture?
Luther reopened the question of the Canon of the O.T., and instead adopted the Canon of the Medieval Jews who had rejected the Messiah and His Holy Scripture as the Church had understood it for 1400 years.
Other protestants rejected letters from the New Testament formerly respected, such as Clement, and scholars began to question the authorship of some of Paul's letters.
In the end, there has still remained fundamental differences regarding the Canon of both Old and New Testaments between the four largest groups of believers, namely Catholics, Orthodox, Protestant,and Jew.
The text of the New Testament has also come under question as manuscripts began to be collected and compared for the purpose of printing a definitive text of both the original Greek and Hebrew.
Finally, the translation, both the general style and specific methodology of translation, as well as the necessary research and reference material has had to be painstakingly gathered, such as Hebrew and Greek grammars and dictionaries, and studies of the vocabulary and style of these languages throughout the history of their usage.
The question of doctrinal and theological bias in both translation and interpretation has also been raised by the very act of Protestants from the Reformation insisting upon going back to the text of the scriptures for all matters of doctrine and behaviour.
In the end, 'Sola Scriptura' has turned out to be a far more complicated proposition than the Protestants ever dreamed. And Protestant scholars are now among the first to insist upon long and careful study of all these matters.
As it turns out, many suspicions and skeptical attacks upon the bible have been proven to be unfounded by careful analysis, historical research, and Archaeology. But many other questions either remain, or have become even more acute problems.
This is why the Reformation could not be accomplished in 'a week', nor could all the problems or errors of Christians and the church be repaired so easily. In fact, the Reformation is just one small part of a long ongoing process prophesied long ago, that in the Endtimes, knowledge would be greatly increased, and yet paradoxically, so would confusion and apostacy.
Christians have to carefully examine what is 'sure' in our faith and doctrine, and defend it, while acknowledging humbly those parts of our knowledge and wisdom in which we 'see darkly' or lack true understanding.
