Christian radicalism

The Waldensians, also known as Waldenses (), Vallenses, Valdesi, or Vaudois, are adherents of a church tradition that began as an ascetic movement within Western Christianity before the Reformation. Originally known as the Poor of Lyon in the late 12th century, the movement spread to the Cottian Alps in what is today France and Italy. The founding of the Waldensians is attributed to Peter Waldo, a wealthy merchant who gave away his property around 1173, preaching apostolic poverty as the way to perfection.

The Adamites, also called Adamians, were adherents of an early Christian sect reportedly active in North Africa during the 2nd through 4th centuries. According to ancient sources, the group practiced ritual nudity, believing they had regained the primeval innocence of Adam and Eve before the Fall. Similar beliefs and practices were attributed to various groups in medieval and early modern Europe, whose adherents were also labeled Adamites by contemporary chroniclers.

Restorationism, also known as Christian primitivism, is a religious perspective holding that the early beliefs and practices of the followers of Jesus were either lost or adulterated after his death, and therefore require restoration. It is a view that often "seeks to correct faults or deficiencies, in other branches of Christianity, by appealing to the primitive church as normative model".

The Levellers were a political movement active during the English Civil War who were committed to popular sovereignty, extended suffrage, equality before the law and religious tolerance. The hallmark of Leveller thought was its populism, as shown by its emphasis on equal natural rights, and their practice of reaching the public through pamphlets, petitions and vocal appeals to the crowd.

Christian devotional practice

The Doukhobors (Canadian spelling) or Dukhobors (; ) are a Spiritual Christian ethnoreligious group of Russian origin. They are known for their pacifism and tradition of oral history, hymn-singing, and verse. They reject the Russian Orthodox priesthood and associated rituals, believing that personal revelation is more important than the Bible. Facing persecution by the Russian government for their nonorthodox beliefs, about one-third migrated to Canada between 1899 and 1938, where most of them reside .
