What were the main criticisms outlined in Martin Luther's 95 Theses that contributed to the Protestant Reformation?

Martin Luther's 95 Theses criticized several practices of the Catholic Church, mainly focusing on the sale of indulgences. Indulgences were payments people made to reduce punishment for their sins, which Luther believed distorted the true message of Christianity. He argued that salvation comes through faith alone and not through buying forgiveness, which he felt exploited the poor and misled believers. For example, Luther pointed out that the church's emphasis on money over genuine repentance was wrong and harmful. His theses sparked a movement that challenged the authority of the Church and led to the Protestant Reformation, as many people began to question and seek reforms in their faith.
