Martin Luther trusted the Word of God more than human tradition.
‘…where the Holy Scriptures do not rule, there I advise no one to send his son. Everyone not inceasingly busy with the Word of God must become corrupt; that is why the people who are in the universities and who are trained there are the kind of people they are. For this no one is to blame with the training of the youth. For the universities ought to turn out only men who are experts in the Holy Scriptures, who can become bishops and priests, leaders in the fight against heretics, the devil and all the world. But where do you find this true? I greatly fear that the universities are wide gates of hell, if they do not diligently teach the Holy Scriptures and impress them on the youth.’
