Evangelicalism (), also called evangelical Christianity or evangelical Protestantism, is a worldwide, interdenominational movement within Protestant Christianity that emphasizes evangelism, or the preaching and spreading of the Christian gospel. The term evangelical is derived from the Koine Greek word euangelion, meaning "good news," in reference to the message of salvation through Jesus Christ. Evangelicalism typically places a strong emphasis on personal conversion, often described as being "born again", and regards the Bible as the ultimate authority in matters of faith and practice. The definition and scope of evangelicalism are subjects of debate among theologians and scholars. Some critics argue that the term encompasses a wide and diverse range of beliefs and practices, making it difficult to define as a coherent or unified movement.
The theological roots of evangelicalism can be traced to the Protestant Reformation in 16th-century Europe, particularly Martin Luther's 1517 Ninety-five Theses, which emphasized the authority of Scripture and the preaching of the gospel over church tradition. The modern evangelical movement is generally dated to around 1738, influenced by theological currents such as Pietism, Puritanism, Quakerism, and Moravianism—notably the work of Nicolaus Zinzendorf and the Herrnhut community. Evangelicalism gained momentum during the First Great Awakening, with figures like John Wesley and the early Methodists playing central roles.
