Protestant communities are groups of Christians who follow the teachings of the Reformation, a movement that began in the 16th century. These communities emphasize the authority of the Bible and the belief in salvation through faith alone, rather than through works or church rituals. There are many different denominations within Protestantism, such as Baptists, Methodists, and Lutherans. Each denomination has its own beliefs and practices, but they all share a common foundation in the principles established during the Reformation. Protestant communities can be found worldwide, contributing to diverse cultural and social landscapes.
