What were some of the major grievances Martin Luther had with the catholic church

Explanation:

Martin luther had proposed his 95 thesis to the catholic church. 

Which ended up getting him excommunicated by the pope. The 95 Thesis explained the true meanings of what the bible truly said, proving the pope to be a liar,cheat and wrong. The pope was telling the people that the way to getting into heaven was by paying the church, and paying money would clear them from their sins. Martin Luther began his 95 thesis conserning these rules. He began to change them into the correct wording. Meaning instead of lying to the people like the pope, Martin wrote the true words of God. One wrote "As long as you have faith in the lord, you are able to enter into the holly lands". 

Explanation:

Martin Luther (November 10, 1483–February 18, 1546) was a German professor of theology, composer, priest, monk and seminal figure in the Protestant Reformation. Luther came to reject several teachings and practices of the Roman Catholic Church. He strongly disputed the claim that freedom from God’s punishment for sin could be purchased with money, proposing an academic discussion of the practice and efficacy of indulgences in his Ninety-five Theses of 1517. His refusal to renounce all of his writings at the demand of Pope Leo X in 1520 and the Holy Roman Emperor Charles V at the Diet of Worms in 1521 resulted in his excommunication by the pope and condemnation as an outlaw by the emperor. Luther taught that salvation and, subsequently, eternal life are not earned by good deeds but are received only as the free gift of God’s grace through the believer’s faith in Jesus Christ as redeemer from sin. His theology challenged the authority and office of the pope by teaching that the Bible is the only source of divinely revealed knowledge from God, and opposed priestly intervention for the forgiveness of sins by considering all baptized Christians to be a holy priesthood. Those who identify with these, and all of Luther’s wider teachings, are called Lutherans, though Luther insisted on Christian or Evangelical as the only acceptable names for individuals who professed Christ.
