Martin Luther was fighting for the Bible in a day where the predominant religious mindset was that money influences God. He wanted to focus God’s people on what the Bible says rather than on what the religious institutions taught. There is a great article on Luther at DesiringGod.org. Luther elevated the Biblical text itself far above all other commentators, including the venerated Church Fathers. This is great lesson for us! We should exalt the Bible because the Bible exalts God.
