Martin Luther (10 Nov 1483 – 18 Feb 1546) was a German friar, priest, professor of theology and a significant figure in the Protestant Reformation. Luther denounced a number of teachings and practices of the Catholic Church. He strongly disputed the claim that freedom from God's punishment for sin could be achieved through indulgence or other financial means. His translation of the Bible vernacular made it more accessible for common folk, which had a massive impact on German culture. Martin Luther died convinced of the correctness of his Reformation theology, and with his decree of excommunication by Pope Leo X effective up to date.
Martin Luther's 95 Theses is one of his most notable and significant works, one of keystones of Christian reformation. These 95 theses challenge traditional ways of Catholic Church, many of which appear immoral and senseless, like indulgences – papers granting God’s forgiveness, that anyone could by for money. A very thoughtful and educative reading, regardless of your relation to Christianity.
