What is the essence of the teachings of Martin Luther?

The teachings of Martin Luther King were created in the late Middle Ages. It contained objections to Catholic orders and dogmas. The rise of Protestantism came after the publication of Martin Luther’s theses against indulgences. This became a fundamental factor in the development of further beliefs. The problem of abuse of authority by the Catholic Church was relevant in medieval society. People were outraged by the existence of indulgences – special letters that absolve sins, church taxes and the Inquisition.
