Why was martin Luther known as catalyst of the protestant reformation?

Answer 1

Martin Luther is known as a catalyst of the Protestant Reformation primarily for his Ninety-Five Theses, which he famously nailed to the church door in Wittenberg in 1517. This document criticized the Catholic Church's practices, particularly the sale of indulgences, and called for a return to biblical teachings. Luther's actions sparked widespread debate and ultimately led to the formation of various Protestant denominations, challenging the authority of the Catholic Church and reshaping the religious landscape of Europe. His emphasis on faith and scripture laid the groundwork for modern Protestant beliefs.
