During this time, long-existing beliefs stemming from the teachings of the Roman Catholic Church began to be understood from new perspectives as humanists—individuals who placed emphasis on the human body and its full potential—began to shift focus from the church to human beings themselves. Humanists began forming new beliefs in various forms: social, political, and intellectual. The ideals of the Renaissance were evident throughout the Protestant Reformation, which took place simultaneously with the Renaissance. The Protestant Reformation began with Martin Luther's rejection of the selling of indulgences by Johann Tetzel and other authorities within the Roman Catholic Church, resulting in Luther's eventual break-off from the Roman Catholic Church in the Diet of Worms. After Luther was excommunicated from the Roman Catholic Church, he founded what was then understood to be a sect of Catholicism, later referred to as Lutheranism. Luther's preaching in favor of faith and scripture rather than tradition led him to translate the Bible into many other languages. The Italian language was able to spread even more with the help of Luther and the invention of the printing press by Johannes Gutenberg. The printing press facilitated the spread of Italian because it was able to rapidly produce texts, such as the Bible, and cut the costs of books which allowed for more people to have access to the translated Bible and new pieces of literature. The Roman Catholic Church was losing its control over the population, as it was not open to change, and there was an increasing number of reformers with differing beliefs.
