Born 10th November 1483, Martin Luther was a member of a monastic order and a Roman Catholic priest who became the founder of the Protestant Reformation. The key objective of Luther was to reform the Roman Catholic Church and not to leave it. The sale of indulgences was one of his first disputes with the Church. The notion on which these indulgences were based was that an excess of merit was stored up by the saint beyond the requirements for their own salvation. This excessive of merit was a type of metaphysical treasury of merits.
These excess merits can be dispensed by the Church as indulgencies for shortening the time of other people present in Purgatory. For example, for the parish church, a new roof may be purchased by an adulterer and in return of it, he would be assured by a bishop that he will not spend time for his sin in Purgatory. Luther perceived that such type of system was immoral and cannot work.
Martin Luther had been a devoted religious scholar, a monk, and a disciple of the Catholic Church who served his life in teaching and practicing the central tenets of Christianity. However, he decided to split with the Catholic Church, as it was a matter of principle of integrity for him. He was disgusted by the practice Church’s hierarchy of providing absolution in return for compensation. This practice was disillusioned by the eminent fallibility was also known as the doctrine of indulgences.
Martin Luther witnessed this practice among his fellow-men of faith whose daily works appeared to be separated from the original meaning and world of the Bible. Changes were then agitated by Martin within the Church. He was overall a man of true integrity and faith who found it impossible to stay inside the Church due to the corruption prevailing over there.
