How did luthers ideas lead to a break with the church and to a new faith?

Martin Luther's ideas, particularly his emphasis on justification by faith alone and the authority of Scripture over Church tradition, challenged the Catholic Church's practices, such as the sale of indulgences. His posting of the Ninety-Five Theses in 1517 sparked widespread debate and reformist sentiment, leading many to question the Church's authority. This movement ultimately resulted in the formation of various Protestant denominations, marking a significant break from the Catholic Church and the establishment of new faiths based on Luther's teachings.
