Martin Luther (1483 - 1546)

He believed that the papal authority in granting indulgence by sale was being abused. After a long deplomatic protest against it, he led the German churches to sever from the Roman Catholic hierarchy. This marked the birth of the protestant churches. Luther agrees with Ockham that reason unaided by faith and grace cannot discover God. Reason is finite, faith infinite, thus things impossible to reason are possible by faith. Based on Romans 1:17, the just shall live by faith, Luther agreed that a christian has in his faith all that he needed, and needs no work to justify him. On politics Luther admonishes that the individual must obey the ruler no matter the perverseness of his command.
