Rationalists object to the phenomenological and functionalist approaches, arguing that they fail to understand why believers in systems of non-scientific knowledge do think they tell the truth and that their ideas are right, even though science has shown them to be wrong. We cannot explain forms of knowledge in terms of the beneficial psychological or societal effects that an outside observer may see them as producing. We have to look at the point of view of those who believe in them. People do not believe in God, practice magic, or think that witches cause misfortune because they think they are providing themselves with psychological reassurance, or to achieve greater cohesion for their social groups. They do so because they think their beliefs are correct – that they tell them the truth about the way the world is.
History records Martin Luther as a savior of Christianity. He was concerned with the well-being of the Catholic Church and its policy of granting forgiveness through indulgence rather than penance. Luther's actions were neither cinematic nor groundbreaking. The message of 95 Thesis gave the summary and expressed the feelings of many of his peers already had about the corruption of Christ's teachings.
Luther illustrated the spiritual, material, and psychological truths behind abuses in the practice of buying and selling indulgences. He was not out to pick a fight or to have his own way; his purpose was to uphold the truth, for the cause of Christ.
