Much of the history of the Reformation depends on the ideas of Martin Luther. Because of him, the revolt was more ecclesiastical than theological, except in the fundamental difference of Protestant dependence on faith for salvation and Catholic dependence on the sacraments of the Church. The basic principle on which Luther based his reconstruction of theology was that individual salvation from sin and its punishment was to be obtained by personal faith in Christ as a sufficient Savior rather than faith in the priest, the sacraments, and the whole system of Catholicism.
Martin Luther (1483-1546), the hero of the Reformation, was born in the village of Eisleben. He entered the University at Erfurt in 1501 and graduated with honors. In 1505 he entered an Augustinian monastery at Erfurt and was consecrated to the priesthood in 1507.
