Luther was a monk who resided in Germany in the early 1500's. He strongly believed
in Christianity, and also was a member of the Catholic Church. He devoted his whole
life to his religion and promised to himself that he will never get married and
will regularly, and will fast to prove his faith in God. He studied Bible and extend
its teachings to other people in his town.
The Catholic Church has
belief and faith that good works will take you into heaven. Luther clearly
disagreed. He also didn't like the selling of pleasures.
