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.
Marx sharply criticized the contemplative materialism of the Young Hegelians, viewing "the essence of man" in isolation and abstraction , instead arguing that the nature of man could only be understood in the context of his economic and social relations.  Marx argued that understanding the origins of religious belief were not enough in moving towards its elimination; instead declaring that it was the underlying social and economic structure which gave rise to religious belief and that it was a transformation of this which was a necessary precondition to the elimination of religion.
