Martin Luther condemned clerical abuses, especially the sale of indulgences in the Ninety-Five Theses. This document is considered the catalyst of the Reformation.
Martin Luther King Jr. did not write the 95 theses. Martin Luther, a medieval monk, wrote the 95 theses. This was a list of why the Roman Catholic Church was wrong in selling indulgences.
His cause of posting the 95 theses was because of the selling of indulgences. Indulgences was a thing that would take you directly to heaven even though you did a bad thing. Did this help:D
What he supposedly posted on the Wittenberg Castle Church door on October 31, 1517 was the 95 Theses or called " A Disputation on the Power and Efficacy Indulgences".
The 95 Theses centers on agreements within the Catholic Church regarding baptism and absolution. The Theses offer a view on the validity of indulgences (remissions of temporal punishment due for sins which have already been forgiven). They also view with great cynicism the practice of indulgences being sold, and thus the penance for sin representing a financial transaction rather than genuine contrition. Luther's theses argued that the sale of indulgences was a gross violation of the original intention of confession and penance, and that Christians were being falsely told that they could find absolution through the purchase of indulgences.
Luther posted the 95 theses, because he was upset about the indulgences that Johann Tetzel had been selling and the papal keys sold by the pope, because both were using the income for themselves not the church out of greed.
Martin Luther (NOT King!) wrote his 95 theses against indulgences and other church abuses, and nailed them on the door of the Castle church in Wittenberg, Germany in 1517.
