Devotio Moderna (Latin; lit., Modern Devotion) was a movement for religious reform, calling for apostolic renewal through the rediscovery of genuine pious practices such as humility, obedience, simplicity of life, and integration into the community. It began in the late 14th century, largely through the work of Gerard Groote,[1][2] and flourished in the Low Countries and Germany in the 15th century, but came to an end with the Protestant Reformation.[2] It is most known today through its influence on Thomas à Kempis, the author of The Imitation of Christ, a book which has proved highly influential for centuries.[1]
This movement largely believed in austerity for Christians at every level, from clergy to layman, and many followers of Devotio Moderna frowned upon such things as church-led celebrations of certain events.[3]
