Protestanten are members of a branch of Christianity that originated in the 16th century during the Reformation. This movement sought to reform the Roman Catholic Church and led to the establishment of various denominations, including Lutheranism and Calvinism. Protestants emphasize the authority of the Bible and the importance of faith in Jesus Christ for salvation. Protestantism is characterized by diverse beliefs and practices, with each denomination having its own interpretations of scripture and worship styles. Common themes include the priesthood of all believers and the rejection of certain Catholic traditions, such as the veneration of saints and the authority of the Pope.
