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.
If you discover that another academic has written a thesis on a topic similar to your own, don't stress out. Carefully read the material to gain an understanding of what it is that the prior thesis has accomplished and consider ways your thesis might further develop the topic or might approach the topic from a totally different perspective. You are likely to find that the former thesis is not the same as the one you are considering after all. To be sure, show the competing thesis to your advisor; he or she can give you indispensable advice. If you discover that another graduate student is writing a thesis on the same topic you've chosen, you could also consider contacting that author to get an even better idea of whether your ideas overlap. (Be careful not to give away too much of your own thinking on the topic as you conduct this discussion.)
