“Though there were several precursors of the Reformation (John Wycliffe, John Hus, Savonarola), the Reformation proper began with Martin Luther of Germany (1483-1546)…The Reformation then began on Oct. 31, 1517 when he nailed his “95 Theses” to the door of the Wittenberg Church…Originally Luther felt Roman Catholicism could be salvaged; in time he and the movement saw this was hopeless and branched out — with God’s blessings.
Martin Luther was one of the most prolific writers of all time, and among the top 5 Christian writers in output…He wrote no formal systematic theology per se, but his views are summed up in his Short and Larger Catechisms. His commentaries on Romans and Galatians were his expository masterpieces. But most germaine to our study is his theological masterpiece: The Bondage of the Will.
Luther’s theology revolved around the doctrine of justification by faith alone, without works of the Law” (Curt Daniel, The History and Theology Of Calvinism, p. 18, Good Books, Springfield, 2003)
