The hallmark of Protestant liberalism can be seen, in simplest terms, as the inversion of authority.  Dating from the Reformation, authority for the Protestant faith was rooted in the concept of "biblical authority," a scheme in which the Christian canon of scripture was considered to be an epistemological given backed by a divine guarantee, thus assuring an unquestionable source of certainty for Christian faith and practice.  While human reason was considered by the reformers to be part of the ''imago dei'' (the image of God within man), they nevertheless insisted that truth could only be understood when reason submitted to the authority of scripture.  Harnack and his colleagues essentially reversed this equation and proceeded on the assumption that truth could only be understood when everything, including scripture, submitted to the authority of reason.
