17th Century on Rational Faculties

Whereas the medieval doctors had assumed that the fall affected primarily the will and its affections and not the reason, the Reformers assumed also the fallenness of the rational faculty: a generalized or “pagan” natural theology, according to the Reformers, was not merely limited to nonsaving knowledge of God—it was also bound in idolatry. This view of the problem of knowledge is the single most important contribution of the early Reformed writers to the theological prolegomena of orthodox Protestantism. Indeed, it is the doctrinal issue that most forcibly presses the Protestant scholastics toward the modification of the medieval models for theological prolegomena.
