The major individualistic reform movements that revolted against medieval scholasticism and the institutions that underpinned it were humanism, devotionalism, (see for example, the Brothers of the Common Life and Jan Standonck) and the observantine tradition. In Germany, "the modern way" or devotionalism caught on in the universities, requiring a redefinition of God, who was no longer a rational governing principle but an arbitrary, unknowable will that cannot be limited. God was now a ruler, and religion would be more fervent and emotional. Thus, the ensuing revival of Augustinian theology, stating that man cannot be saved by his own efforts but only by the grace of God, would erode the legitimacy of the rigid institutions of the church meant to provide a channel for man to do good works and get into heaven. Humanism, however, was more of an educational reform movement with origins in the Renaissance's revival of classical learning and thought. A revolt against Aristotelian logic, it placed great emphasis on reforming individuals through eloquence as opposed to reason. The European Renaissance laid the foundation for the Northern humanists in its reinforcement of the traditional use of Latin as the great unifying language of European culture.
