Protestantism - Luther's 95 Theses

Luther's 95 Theses

In 1517, Martin Luther, a German Augustinian friar, published the 95 theses. Popular history holds that these were nailed to a church door in the university town of Wittenberg by Luther himself, but this claim has recently come under scrutiny (see article on Martin Luther for discussion). Luther's propositions challenged some portions of Roman Catholic doctrine and a number of specific practices.

Luther was particularly criticizing a common church practice of the day, the selling of indulgences. In Catholic theology, an indulgence was the full or partial remission of temporal punishment due for sins which have already been forgiven. However, Pope Leo X had declared that indulgences were not only for the remission of temporal punishment, but also for guilt itself. To Luther, it appeared that selling indulgences was tantamount to selling salvation, something that he felt was against both biblical teaching and Roman Catholic doctrine. At the time, Rome was using the sale of indulgences as a means to raise money for a massive church project, the construction of St. Peter's Basilica.

The Disputation of Doctor Martin Luther on the Power and Efficacy of Indulgences (commonly known as the 95 theses) was a request for a formal disputation that criticized the practice of selling indulgences. This kind of disputation was a common academic exercise during this era. Luther maintained that justification (salvation) was granted by faith alone, saying that good works and the sacraments were not necessary in order to be saved. A copy of the disputation eventually made it to the hands of the regional bishop, who in turn forwarded the disputation to Rome.
