Even with the fact that it is difficult to determine the exact purpose of Luther's writing, it is only safe to assume that it stands as a basis for the Reformation movement. It is very probable that Luther did not actually intend this text to be an attack on the pope, as he actually wanted to question particular matters regarding the Catholic Church. One of his main concerns is obviously that of condemning indulgences, given that it was virtually impossible for a moral individual to understand them. In wanting to have local theologians actively engaged in discussing his topics, Luther went against the Church and led to one of the most important revolutions in the history of Christianity. Luther did not want to relate to God in his theses, considering that most of the subjects he discusses involve people and their inability to observe the injustices...

The German theologian wanted people to understand that they did not need mediators to create a connection between God and them. Also, in their supposed campaign to improve conditions in the world, some of the most influential members in the Catholic Church ignored those who were in reality suffering in favor of attending the needs of wealthy individuals, since they were willing to pay in order to receive preferential treatment.
Luther's perspective was not unique, since many of his contemporaries shared this view, as it would be absurd for one to consider that sins can actually be forgotten in exchange of money. He was reluctant to accept the concept that the pope was more than a tool in the hands of God, especially given that many popes went far beyond their sphere of influence at the time.
